A small, self-contained power plant that does not produce any emissions and needs to be refueled only once every five years might sound pertty perfect. But then we have to utter EcoGeek's forbidden word: Nuclear.
Hyperion Power Generation is promoting a new design for a small scale nuclear power system developed at Los Alamos National Laboratory that is being touted as a cleaner, greener method for providing nuclear power. "The portable nuclear reactor is the size of a hot tub. It’s shaped like a sake cup, filled with a uranium hydride core and surrounded by a hydrogen atmosphere. Encase it in concrete, truck it to a site, bury it underground, hook it up to a steam turbine and, voila, one would generate enough electricity to power a 25,000-home community for at least five years."
But the developers don't like to call it a "reactor" (in part, no doubt, because of the numerous negative connotations that "reactor" carries).
Though it would produce 27 megawatts worth of thermal energy, Hyperion doesn’t like to think of its product as a “reactor.” It’s self-contained, involves no moving parts and, therefore, doesn’t require a human operator.“In fact, we prefer to call it a ‘drive’ or a ‘battery’ or a ‘module’ in that it’s so safe,” Hyperion spokeswoman Deborah Blackwell says. “Like you don’t open a double-A battery, you just plug [the reactor] in and it does its chemical thing inside of it. You don’t ever open it or mess with it."
There are a lot of questions that need to be asked.
Even if it is a smaller, safer device, a lot of people are not going to want to have these in their neighborhoods, or anywhere near them. Could I dig one up in the middle of the night and use the materials inside to make a bomb? What to we do with the waste at the end of those five years? Where are we going to get all the uranium necessary? These are nuclear questions that nuclear experts tend to not want to answer.
We certainly hope that there is a lot more information forthcoming before anyone decides to start deploying and manufacturing this on any scale.

But I can see why other parts of the world would consider this.
If you did a cost/benefit analysis comparing deaths resulting from accidents with these devices and deaths from pollution caused by a coal-fired plant, these might well come out on top.
But from the point of view of citizens rather than corporations its going to be better to turn energy research dollars into making spray on solar/ultra-capacitors a reality.

I for one would volunteer this for my backyard.. Lets see now:
Option 1:
No electricity, industrial age over, no/little hear. Pray some one invents a non-polluting, non co2 energy source that will work without oil.
Option 2: Fridge size nuclear reactor, safely buried. VERY cheap electricity, electric heat, lights, charger for my new electric only car.
Of course 100% solar and wind would be better, but that isnt going to happen in this lifetime.
This is a no brainer.

Weapons grade material is not used in reactors, it's too pure.
What to we do with the waste at the end of those five years?
Recycle it to make more fuel.
Where are we going to get all the uranium necessary?
Same place we get our current uranium or we could make our own.
These are nuclear questions that nuclear experts tend to not want to answer.
No, you just don't want to listen to the answers.

1. You can make weapons with reactor fuel...if not atom bombs, then dirty bombs.
2. Using spent fuel to make more fuel doesn't work indefinitely, and it definitely does not work in this kind of reactor, which needs a very specific kind of uranium
3. Uranium mining is dangerous, costly, and environmentally harmful. I'm sure we could do MORE of it...but I'm not sure we want to.
When they do answer, I listen...but I don't especially like the answers.
written by EV, December 01, 2007
2. That's where breeder reactors come into play. Or we could just use better reactors that don't require one specific type.
3. And once we have enough, breeder reactors will give us the material we need for a few thousand years.
Never said you would.

just add: coal mining is bad too. and coal fuel burning puts a lot of bad stuff in the air (including radioactives). So going for uranium might not be that bad of a thing.

Well I have been looking from some of the science papers from these people so I can figure out exactly how this things works, but I have had no luck. If anyone knows where I can find the full technical break down could you email me?
But with out the full break down it is hard to see how good/bad this thing might be, but my gut reaction is that it will have the same problems (in the US at least) as other nuclear power plants. And if it needs a special Uranium isotope then the mining problem just because way out of hand (but I think it might need a special H isotope not U). I guess we will just have to wait and see
But it could be very useful for some specialized cases. Personally I want to put one at the south pole so we can have enough on site power generation for our research so that we don't have to fly EVERYTHING in... I'll check back once some one has lost it over that comment, but I'm not really worried about the terrorist stealing it there.

I am not sure that this, or any reactor, would just be left unguarded and buried. If that were the case, the application would never pass the NRC's mail room.
As for where all that uranium comes from, well, we could further develop the technology to recover the fraction that is part of seawater (3ppb) and that would power the planet for longer than humans have inhabited it. This would all but eliminate the mining issues.
Uranium from seawater is currently expensive, but, the cost of fuel is a tiny fraction of the cost of nuclear operations, so even if it cost three times as much the impact on the bus-bar cost of electricity would be negligible. As for the environmental impact of this, it is benign is done correctly.
But anti-nuclear folk will always raise the other issues, like cost and waste and bombs and things that are not really problems. if you take all of the spent fuel waste ever generated in the us, it is about a football field wide and long and about 10 yards tall. And nuclear is the only energy generation field that takes care of there waste, or at least cognizance of it.
I think i could go on and on, but as most studies on public perception of nuclear power go, there are those that are pro, those that are anti and those that are apathetic... the apathetic ones are the only ones whose opinions change.

Excusing my limited knowledge of chemistry and physics, but it works something like this:
The low levels of radiation produced by the uranium hydride causes the surrounding hydrogren to turn into tritium which is radioactive (but which poses little hazard). As the tritium deteriorates through its short half life, that energy is converted into electricity.
The uranium hydride used has less atomic mass than is required for bombs and would need enrichment. Thus only those with massive amounts of the stuff, plus an enrichment facility, plus means to transport it, etc. It's very unlikely it could be stolen and smuggled without being noticed.
Of course, that explanation is based on high school physics, 101 college science and Isaac Asimov books. Somebody else probably (read: undoubtedly) has a better answer; please put me out of my misery if you have a better explanation.
If the automakers stopped screwing around and started working with the energy industry to do this, we could have electric cars and homes with no emissions at all. They've both got cash, so they should get off their rumps and do the R&D!

It'd require 12,000 Nuclear stations in America alone. 320,000 if you wanted to extend the concept to the world.
The first question, of course, would be "who gets to put this in their backyard." Especially in urban areas where there's millions (or hundreds of millions) of people and not much space to keep micro-facilities like that away from housing. But it goes further than that.
Needing to be refueled every 5 years sounds like a good idea, until you think about the fact that it's one of the numbers above (depending on how far you'd like to see the idea implemented) worth of uranium that'd need to be replaced (i.e. the old material discarded) every 5 years.
It sounds like a fantastic idea when you think about just one of these facilities. But if you scale it out to the number needed to cover the country - or the world - you can begin to see where the waste management problem comes in. This ain't no ordinary waste.
You also have to wonder about the level of security needed for those 12,000 (or 320,000) sites. Who's going to stop someone from messing with them? That's a lot of new micro-sites to manage. This is one of the reasons why we tend to build large facilities today. It's easier to defend one large facility than a thousand small ones.
The next question would be "HOW do you replace the fuel?" If it's been buried and encased in Concrete, does that mean that each of these 12,000 (or 320,000) sites is going to have to undergo major construction efforts every 5 years to un-bury and expose the core so that the spent fuel can be removed and new fuel inserted?
This is beginning to sound like a less and less efficient idea.

I wonder how small these things are. If they were truly small (like the size of a car battery), the government could probably buy up a couple hundred square miles in a midwest state and throw the entire thing in there... then just secure that site. But I can't seem to find any size estimates anywhere at the moment, so I don't know how feasible that would be.
In regards to the energy usage in other countries, I think it would still be safer to assume that one day these countries may/will use as much energy as we do. There was a time, not long ago, when China hardly used any energy in comparison to us. Their economic surge turned that tide quicker than anyone ever predicted. It's always good to prepare for the worst (or best I guess, if you're in one of those countries and would prefer to have more power available) case scenario I think.
I do like the idea of it not producing any waste water, which the manufacturer's site claims.
If the manufacturer would take care of the logistical problem of refueling, that could be good... as long as there's an efficient way to do so. If they went out of business with the time/costs needed to do the refueling, we'd be right back to where we were before. The manufacturer's site says that they have to open the device to refuel it, which definitely implies unearthing/removing it from the concrete first.
All I can say is that I wouldn't want to pay that company's maintenance bills. =)

The number provided that it could power 25000 homes can not be projected to a world wide total because it most likely meant 250000 American homes which are energy drains compared to other countries.

These small reactors are safe, affordable, scaleable, and make good sense. Also, these units can be designed so that the entire concrete vault is lowered by crane to it's "vault", and when it is time to refuel, they replace the "spent" device, like a battery, and they can take the old one back for referbishing. Less down time, lower cost. The article states that these units are about the size of a hot tub (about 8 feet square?), so they would easily fit on a flat bed truck for transportation, or even a secure railcar.
About the US consumption of electricity... I do not consider it gluttony, but progress. When you upgraded your processor, you decided to use more poewr. Your air conditioner, water treatment plants, the servers over at Google, even the printing of your paycheck was run by electricity!

Therefore, let's not complain about our electricity usage, but augment our capabilities to reduce the true problem- petrolium and coal based energy!

So for Los Angeles with it's 20 million people, you can install 400 units in one site, and 400 units in another site.
Instead of taking 400 small ones and put them together, why wouldn't they just make one big one? As it was stated before, large plants have greater efficiency and are easier to protect.
I thought I'd throw this out there for people concerned with meltdowns and other safety issues:
I recently visited Indian Point, and one of the things they told us and demonstrated to us was the speed with which they could shut the plant down. To go from full power to no power takes less than 2 seconds. With responsiveness like that, it would take a large scale combination of mistakes and failures to create a real problem. While this such occurrence is not impossible, the chances of it happening are astronomically small.

Never put all your eggs in one basket. even though well protected, if only one large plant is attacked or goes off line, there needs to be redundant systems to pick up the slack. This is why there are normally many small turbines at dams and other power facilities, instead of less larger sized Units.
Also, these units do not produce electricity, but HEAT. They are to be connected to a Steam Turbine in order to produce the steam to power the generators. Therefore, they can also be used in existing plants that burn coal to heat the water into steam. Just replace the boilers with these new units.
these were designed to be small so that they would not overheat and melt down. Increasing the size increases the heat, meaning they will have to be monitored and then there is more room for mistakes and a higher cost of operation. These were specifically designed for small towns and third world countries with limited technitions and funds, but have a wide application when scaled. Just hook up the water input to each unit, and connect the steam out to a common manifold, and you can connect say 10 small units to one large steam powered generator. So the Generators can be large scale, but the "nuclear Batteries" stay small and easier to manage. Also, with multiple batteries, when one goes down, the plant does not go offline, it only has to reduce it's capacity accordingly.
Hopefully the department of energy is reading this blog and taking notes, as many of the commentors have great ideas!

these were designed to be small so that they would not overheat and melt down.
The original design for these plants was not to decrease the likelihood of meltdown, but to provide a lasting energy source to remote areas. While its true their purposefully small design was engineered to reduce the probability of meltdown, all reactors being designed today have this feature, called passive safety.
Gen IV nuclear reactors, such as the pebble bed systems, have been designed by the major power firms all have this intrinsic safety feature in their design such that engineers could simply walk away or major control systems could malfunctions and the reactors would safely turn off. The nuclear power industry has learned from past designs (and more notably flaws) and created incredibly safe reactors by anyone's standard.
As for the DOE, as a student of nuclear engineering let me state that the government and the industry are way ahead of bloggers on this. I'm sure if any ideas of merit come out of the blogs though the industry would leap on them and probably even call them their own :-.
Still, these small "battery" reactors only make sense for places like Alaska where the demand for heating and power are great while conventional energy sources just can't cut it, but in large cities with great transportation systems it makes no sense to bury something so expensive that you can't refuel. There's a good reason that systems like these weren't built as the first nuclear reactors even though we had all the technology for these back in the 60s; they're in efficient for large scale power production.
And finally @ Will
Instead of taking 400 small ones and put them together, why wouldn't they just make one big one? As it was stated before, large plants have greater efficiency and are easier to protect.

* Cut oil demand: 50% by 2020
We must reduce oil imports from around 65% to 10%. We can reach these goals in part by getting the 100 mile per gallon (mpg) car into the marketplace, pushing fuel economy standards to 50 mpg by 2020, and setting a life-cycle low-carbon fuel standard that reduces the carbon impact of our liquid fuels by 30% by 2020, including increasing use of alternative fuels.
* Change to renewable sources for electricity: 50% by 2040
I am calling for a national renewable electricity source portfolio standard of 30% by 2020 – which will rise to 50% by 2040. This is aggressive, but necessary as we start using more electricity for automobiles. I will push for an energy productivity law requiring a 20% improvement in energy productivity by 2020. We could save customers $21 billion a year by 2020.
* Dramatically reduce greenhouse gas emissions: 90% by 2050
20% by 2020, and 80% by 2040 -- ten years faster than scientists say is necessary, because we must lead the world, and we can’t afford the possibility of backsliding and inaction. We will start with a market-based cap and trade system for greenhouse gas emissions to create incentives for the electric and industrial sectors to make significant reductions in their carbon emissions. . Economists say the world can protect itself from drastic climate change at a cost of 1-3% of our economic activity. We can afford to protect the climate. Given the risks of catastrophic climate change, we can’t afford not to.
* Lead by example and restore America as the world’s leader
We must return to the international negotiating table and support mandatory world-wide limits on global warming pollution. We will work closely with fast-growing nations and, as President, I will cooperate with the European Union, the World Bank, and other allies to help finance the incremental cost of “doing it right.” I will create a North American Energy Council with Mexico and Canada, which supply about 20% of our oil, and make sure our relations with these neighbors are firm and friendly. As we reduce our demand for foreign oil, we should work with the Persian Gulf nations, and our partners in consuming nations and the United Nations Security Council, to try to create a multilateral system for protecting the Gulf so that within 10 years the U.S. presence there could be sharply and safely reduced.
* Get it all done without breaking the bank
We will raise some revenue from the sales of carbon permits, for example. Further, I will get out the “green scissors” to cut back on wrongly-placed tax subsidies. Over time, this program will yield huge productivity increases in our economy, as well as significant budget savings and revenues. We will create more than 10 times as much value in the American economy by reducing our oil imports as we spend to make this program happen. And everyone - every American - must make an effort to make us energy independent and combat global warming. Our national security and our planet depend on it.

I find this sort of sanctimonious bullshit so tiring. Why would it possibly matter how much energy we're "gluttonously" consuming as long as it's sourced from an ecologically sane resource and won't endanger us? Speaking personally, I think that reverting to the year 1800 in some Amish-esque, self-flagellating rejection of technology and energy wastage is pretty goddamned silly.
Now, don't get me wrong; as an ecologist I'm probably more aware than most of the damage that our current gluttony is doing to the planet and to our society. I think efficiency is something we desperately need to learn. I think we could use a third of our current energy use if we creatively apply technology and good sense to the problem.
But! I refuse to take seriously anybody sanctimoniously bitching about gluttony (while on their computer) while not presenting any cogent solution to the problem. I'd like to figure out a way to live in a way that is simultaneously sane and comfortable. I think it's possible, as long as we stop dragging our asinine fears and finger-wagging into the debate.

While I'm still against having our harbours used as parking spaces for nuclear-powered ships, I think we are in a unique position (with only 4 million people) to have virtually the entire country's power supplied by zero-emission nuclear generators.
New Zealand (with appropriate backing/sponsorship from a nuclear-energy company) could lead the way by becoming the first country to have its power-grid supplied entirely by Zero Emission generators. This idea fits perfectly into the 'Clean, Green' image that New Zealand is renown for, but due to pressure from 'environmentalists', reasonable discussion regarding nuclear power is near-impossible.
The fact is that the safety of nuclear technology has come a long way since the accident at Chernobyl and breeder reactors do a very good job of reducing waste. The way I see it, a situation where you have all the nasty substances concentrated in a single place where you can manage and store them (nuclear waste) is a far better alternative to having the toxins spread out thinly over the globe (radioactive isotopes from burning coal). At least clean up is actually possible with nuclear waste - try cleaning up all the rubbish that coal plants spew into the atmosphere!
Another potential bonus from using nuclear is any surplus power could be utilized to produce hydrogen from water, thus making a hydrogen-powered economy actually feasible from both a economic and environmental standpoint.

How about Canada and Australia...the 2 biggest exporters / reserves in the world? Do you even inform yourself before asking questions?
> These are nuclear questions that nuclear experts tend to not want to answer.
No, these are nuclear questions that people who have no idea about nuclear technology ask.

Guess what? We've already had a rocket with a nuclear payload blow up. Zero radioactive material was released as the material was in a case designed to withstand just such an accident. The material was then reused on a later spacecraft.
nuclear payload fear mongering...

>I would hate to see it blow up in the atmosphere with a nuclear payload, then were in for bigger problems.
- Big unmanned spacecraft (like Cassini) use nuclear 'batteries' (the same concept as in these tub-sized devices). They've already flown over our heads many, many times. Get over the fear mongering, be constructive for once in your life.
--That was shielding there reactors, here we are talking about the using a shuttle in the same purpose as a garbage truck, It is more suitable to use a site like yucca mountain, the wolf river batholilth or even salt domes to store radioactive waste. There have been numerous studies on launching radioactive waste into space but it always comes back to the safety and economics of space travel. It is far safer and cheaper to bury waste at these sites even though there are challenges associated with all these site. Yucca mountain is near seismic activity and is not clear if a facility could isolate the waste for long enough for radioactivity to demise. The wolf river batholith is feared to be part of larger aquifer system that might have drainage into the great lakes. Salt domes are known to have isostatic rebound.
-Launching our nuclear waste into space is science fiction and nothing more. If you think people are pissed off at nuclear reactors (which I support) try to tell them this is how the waste will be eliminated by and you will see a stronger push against reactors than you can imagine.

Furthermore, nuclear power in a life cycle analysis is not carbon neutral. The power it generates does not offset the carbon produced as a result of the creation, maintenance, and fueling. Uranium is heavy, comes from the ground, and needs to be disposed of in ways that will prevent the radiation from hurting us. This all results in CO2 being generated. Granted it is less than a coal plant, but it is still much more than a wind turbine (which offsets it's carbon footprint after about 10 months).
It is VERY POSSIBLE that these two problems concerning nuclear power could be overcome. The issue is that they have not been resolved. On the other hand, technologies like wind power have already been demonstrated as effective at taking care of our energy needs. Using PROVEN technology, instead of relying on possible future technology is very important to moving to sustainable energy creation.

One thing that came to my mind for dealing with the waste is : fungus! there are 2 species (that i know of) that can absorve the radiation and transform it into energy, just like photosyntesis. Maybe we can save worlds hunger too! haha just kidding.
Ps: of course we all know that these are not solutions but patches. the real issue here es capitalism, the use and distribution of products. (example, today we produce food for twice the population of the world, but still people die of hunger)

And this is only the beginning.
Just we have to prepare of something worse may happen at one time, just because of some dangerous minds out there.

Efficiency is the 1st best step to take. You can reduce your usage considerably without affecting your lifestyle. I have reduced mu electricity usage by about 40%. If everyone did similar, then theres a considerable reduction with little effort.

1) Well, why don't you reduce the amount of power you use? There's no reason the US should have to buy power from Canada, or having scheduled blackouts. It's ridiculous. Wake up and realize your using more then you can produce, and THAT'S a problem.
2) Look at what every other country is doing. Are they going to nuclear power? No. Wind power? Yes. Solar power? Yes. The list goes on and on...
3) Do you honestly believe this is going to give you cheaper power? The answer should be no. Why? If everyone actually switched to this, the company running the show would simply jack prices as they now have a monopoly. You certainly can't run it yourself. I bet you think they wouldn't do that. Right... because that's never happened before.
Personally I believe we should all move off the grid. Generate our own power, supply our own water, so what if we have to use less. They maybe we'd actually have some respect for what it means to have such luxuries.

By way of introduction:
I'm the guy who invented the telecommuting feature that lets someone call you at your company's office and the PBX (phone system) transfers the call to your home office.
At my house, "purge water" from the shower (the cold water that is in the pipes before the hot water reaches the shower) goes into a storage tank for use as input to the laundry. And the used water from the laundry goes into another storage tank to flush the toilet. And the washer uses 10 watt-hours per pound of laundry (e.g. 60 watt-hours for a 6-lb load).
I built my own refrigerator/freezer system that saves 1,000 KWH (1 megawatt hour) per year compared to the wasteful old thing that came with the place.
As I write this, my household temp is 62.6 Fahrenheit, and I'm snug & warm in long underwear, knit cap, and scarf, using a 40-watt heating pad on my body instead of a 1,000 watt portable heater for supplemetary warmth.
And my total refuse output per week is less than a 5-gallon bucket, including recyclables.
So I think it's safe to say that, short of going into hunter/gatherer mode, I'm doing more than my share to cut energy & resource consumption and also develop technologies that can be used in the wider market to help others cut consumption levels as well.
With that in mind, I wholeheartedly support these micro reactors, for a reason you haven't heard yet.
There are numerous places that a) have gusty wind that's strong some of the time and weak some of the time, b) are rather remote, and c) only have enough space for a small wind installation, by which I mean 50 MW or less.
These sites are not economically viable to develop for wind power, primarily because of the cost of running the transmission lines to them unless those lines could be kept "full" or nearly so most of the time.
However, with a micro-reactor on the site, that problem is solved. The micro reactor can make up the difference in the power output when the wind isn't blowing, and adjust its output automatically as the inverse of the wind output. Suddenly it becomes viable to pay for those transmission lines. And the micro reactor, running as "backup" to a small wind farm, would need to be refueled far less often.
One could do likewise for solar sites, as backup power overnight (rather than large battery banks that also have to be replaced every five to ten years) and in cloudy weather conditions. You could have a city with photovoltaics on every roof, and a couple of micro-reactors.
In essence, these Hyperion micro-nukes could give us an effectively 100% renewables-based grid, by providing the backup power to overcome the intermittency of wind and sun.
About tritium (re the person who posted that the system relies on turning hydrogen into tritium): the stuff is sufficiently harmless that British Telecom used it to power the lighted dial on their Trimphone in the 60s and 70s. Under the dial number-plate is a capsule of tritium. Has a nice turquoise glow, and is perfectly safe to have on the bedside table. (You can still find these phones around as collectors' items, but by now the tritium has decayed to the point where the glow is very faint.)
And yes, I'd gladly have one in my backyard or in my basement. With one difference. I'd want to install it above-ground, under a small concrete dome for the "retro-cool" look of classic nuclear plant design!

Secondly, as far as renewable energy is concerned, we're only on the first generation of clean energy solutions. The 1970's could be called the beta testing period, and our current renewable energy systems are at stage 1.0. There's no reason why we cannot implement these strategies now and improve on them in the future.
