Port-A-Nuke

Roland Piquepaille writes "Researchers at the U.S. Department of Energy (DOE) are designing a self-contained, tamper-resistant nuclear reactor that can be transported and installed anywhere in the world. In 'US plans portable nuclear power plants,' New Scientist writes that the sealed reactors would last 30 years and deliver between 10 and 100 megawatts. The largest version would be about 15 meters high and 3 meters wide, with a weight of about 500 tons, allowing for transportation by ships or very large trucks. The DOE thinks that this kind of nuclear reactor -- named SSTAR for 'small, sealed, transportable, autonomous reactor' -- would help to deliver nuclear energy to developing countries while significantly reducing the risk of nuclear proliferation associated with the use of nuclear power. What do you think of this idea? Is it a good one or a crazy one? Leaving a nuclear reactor in a developing country which can potentially become unstable during the 30 years of service of the reactor doesn't seem to be terribly safe. Read more before deciding. Anyway, there will be no prototypes before 2015."

It's not like a big box with a lock you break of and grab the fissile material and run. To get to that they need big heavy equipment, specialized training and a good bit of time.

      Irrelevant. These people have guns and can threaten the authorized operators. They can own ("pwn") the site for days if necessary.

      Are you trying to prove you didn't read the article? These units are self contained and sealed. Noone works there. You CANT JUST OPEN THEM UP. There is noone to take hostage. Here let me help you: (2nd and 3rd paragraph from the article):

      The aim is to create a sealed reactor that can be delivered to a site, left to generate power for up to 30 years, and retrieved when its fuel is spent. The developers claim that no one would be able to remove the fissile material from the reactor because its core would be inside a tamper-proof cask protected by a thicket of alarms.

      Reactor in a box

      Known as the small, sealed, transportable, autonomous reactor (SSTAR), the machine will generate power without needing refuelling or maintenance...

You can be fairly assured the government/military will not give you a few days time playing with that thing. What they will do if they can't send in a special forces team is probably just drop a very big bomb on it. Kill everone there, minnimal radiation leak if any, just drop off a new reactor later.

      It's quite easy. Wilderness borders, such as between the USA and Canada, are not hard to penetrate. Expecting border guards to catch 100 pound weapons is not realistic.

      The border between the USA and Canada is a bogous example, because getting the material into Canada in the first place without getting noticed is just as difficult. All border stations have radiation detectors that would go off the scale if you carried a few pounds of fissile material around.

      Bringing it directly into a port city by ship works too. Cargos aren't inspected today, although they will be soon- but even when that happens, the inspectors won't visit cargo vessels until they're already inside the port.

      First, you don't need to inspect cargo to find radioactive material, especially several pounds of it. A few radioactivity meaters will do just fine, and they are already in use in almost all airports, sea ports, and along highwars and all over major cities. People in New York keep getting arrested after radioactive treatments for cancer when they are trying to use the metro (Google for those stories - make for a funny reading). These systems are in place, and they pick up small changes in radioactivity quite readily.

      Wheather the material is in the port is irrelevant (as explained in the portion you decided to leave out in your response). A dirty bomb is still just a regular bomb, the radioactivity has virtually ZERO lethal effect, especially if you're not in a densely populated area (like a sea port). Even then the best you can hope for is to give a few people cancer if you're lucky. IT'S JUST HYPE. The government would hand out iodine pills if something like this happened, and you'll maybe get a situation where the local populations develops a barely noticable higher chance of getting cancer.

Half the core is replaced every 18 months. Burn-up is about 100 GWd/t, and coolant outlet temperature is 850C with a target of 1000C. It is being developed by General Atomics in partnership with Russia's Minatom, supported by Fuji (Japan). Initially it will be used to burn pure ex-weapons plutonium at Tomsk in Russia.

      A smaller version of this, the Remote-Site Modular Helium Reactor (RS-MHR) of 10-25 MWe has been proposed by General Atomics. The fuel would be 20% enriched and refuelling interval would be 6-8 years.

      A third full-size HTR design is Areva's Very High Temperature Reactor (VHTR) being put forward by Framatome ANP. It is based on the GT-MHR and has also involved Fuji. Reference design is 600 MW (thermal) with prismatic block fuel like the GT-MHR. Target core outlet temperature is 1000C and it uses and indirect cycle, possibly with a helium-nitrogen mix in the secondary system. This removes the possibility of contaminating the generation or hydrogen production plant with radionuclides from the reactor core.

      HTRs can potentially use thorium-based fuels, such as HEU with Th, U-233 with Th, and Pu with Th. Most of the experience with thorium fuels has been in HTRs.

    If I recall right, the intention was to provide light (from a shoreline) for ships or to provide heat to stranded sailors in the wilderness, or something similar.

    Unfortunately, the article I read this in was an article looking at how terrorists were/are able to readily find radioactive material throughout the world, but particularly in Russia.

    These things were spread around during the cold war, and then forgot about after the fall of communism. Russia is now playing a "catch-up" game of having to locate and retrieve all these little powerplants, and at the time of this article, they were unable to locate several of them, and of the ones they'd found, several were missing the "vital pieces".

    Similarly, of the ones that they had found, some had been tampered with, some had simply been broken open, probably by nature (with the contents located generally near the remains), and some were a little scarier: Some had been found by unsuspecting people in the area (local residents, hunters, etc), and these people of course became very ill, and in many cases passed away as a result of finding a cracked open, and mysterious case.

    One that sticks with me was a guy talking about how he had found this unusual rod laying on the ground, with all the snow around it melted. He took it home to his family as an oddity...

Both of these countries have significant resources to bring to bear against the problem but have suffered the consiquences of accidents. How could Hati, Trinidad, or some other less sophisticated, resource poor nation deal? The answer is pretty obvious. If something goes wrong, they couldn't.

I took it out and found its white plastic case had turned brownish - and it was obviously failing from the heat. A second one started exhibiting the same symptoms shortly afterwards, so I went back to regular 60 watt bulbs.)

    The "100 watt + vs. 30 watt LCD monitor" suggestion isn't that sensible either, really. If you have a good CRT (like my Sony Trinitron 21"), where's the sense in disposing of it to save some watts of power?
