    Only one company makes and sells BWRs, that being GE. You'll never guess but their first model was the BWR-1. The second was the BWR-2. And so on. The newer the reactor the safer the design and the higher the power output. After awhile, like tech companies, they selected cooler names like the ABWR (advanced) and SBWR and friends. The S stood for something else, but everyone calls it the "safe BWR" instead. The "ESBWR" supposedly stands for "economical (whatever) BWR" but I kid you not people call it the "extra safe BWR" instead. Probably because safe cannot be trademarked.

    These reactors don't have concrete containment shields.

    Not so, not even close. BWR model 3 (example is unit 1 at this site) had a mark1 concrete containment system and BWR model 4 (examples are units 2 and 3 at this site) could have been built with mark1 or mark2 containment systems.

    A gross simplification is mark1 is a big concrete building with a little concrete building inside it and a steel shield inside that little building. In all the pics you can see the big building popped pretty much as designed and the little building inside it is still claimed to be undamaged. Mark1 designs look a lot like really tough office buildings; they look like a telco central office or a modern data center, sorta.

    Mark2 is about the same but for a variety of boring engineering reasons looks like some really giant soda cans (or like a grain elevator). I don't see anything like that on site. I'm guessing either I haven't seen the right pic, or the ancient BWR-4s onsite have a mark1 containment system.

    The newer stuff like the Mark3 look a lot like a swimming pool. I don't know if the undamaged reactor #6 is new enough to have a Mark3.

    Those reactors are already destroyed. They will never be operational gain (it says that in the article I linked to).

    Careful, reactors 1 / 2 / 3 were online hot and currently self destructing due to decay heat. On the other hand, 4 / 5 / 6 were off for maintenance and as far as I know are cold shutdown. They will be restarted in the future assuming they didn't take too much tsunami damage and/or explosion damage from 1/2/3 popping. You will not be too surprised to learn that 1 / 2 / 3 are the oldest reactors, some 40 year old clunkers. The newer design 4 and 5 are not too bad and 6 is actually pretty decent. And they're planning on building some new ABWRs 7 and 8 onsite. One new ABWR generates almost as much power as 1, 2, and 3 put together.

    So the idea is to minimize contamination and damage to reactors 4 / 5 / 6. Remember only one of Chernobyls reactors melted down, the other continued generating power for a decade or something like that.

    All the generators in all of Japan? washed away? I am still here and there are generators around for festivals and the likes, so no. There must be a reason they could not use alternative power sources to power their pumps, and I am curious as to why that is.

    Compare the power level required to flash some light bulbs vs the power level required to inject 50000L/min at a couple hundred PSI...

    One requires a portable honda generator, the other requires a large diesel electric locomotive, or a string of them. Even here, it would be a PITA. There, on the coast, where the tsunami washed away the tracks, and they mostly use electric rather than diesel electric locos...

    To the best of my knowledge they can't even use ship power because either you need a very long megawatt grade power cord, or the ship coolant water intakes will clog.

  10. Re:Journalism on Third Blast At Japan's Fukushima Nuclear Plant · · Score: 5, Interesting

    Sorry to dampen you optimism, but these reactors are going to be totally useless after this. The reactor vessel will almost certainly be beyond repair and it is central to the entire plant. Economically it would be easier to just build a newer design of plant.

    They were planning to build two new reactors onsite, # 7 and #8. They'll probably end up with new ABWRs to replace the old clunkers. Note that a single ABWR outputs as much power as three BWR-3s or two BWR-4s so yanking three 40 year old dinosaurs does not necessarily mean they need to build three new ABWRs to take their place... My guess is they'll get one.

    I'm hardly on their board of directors but most likely instead of adding 2 new ABWRs they'll probably simultaneously build the currently planned two, decon the old units 1 / 2 / 3 and build a nice new ABWR on top of the old site of 1 / 2 / 3.

    Its is possible, that after this excitement, they'll yank all the old BWR-4s and the one decent BWR-5 and replace the whole works with ESBWRs. A pity GE gave up on the SBWR... That design would have been pretty much inherently safe in this situation. Of course I'm a little fuzzy on dates, I think the SBWR design was done a decade or two after the BWR-3 and BWR-4 were built at Fukushima and I don't remember why GE gave up on the SBWR design anyway (maybe the navy or other govt considered it too "sensitive", despite the navy's fondness for PWRs?)

    So what? What use is there in bringing back satellites? That's an utterly stupid requirement

    You have to realize it was a cold war requirement to F with the soviets low altitude photorecon satellites. Back then they launched with actual photographic film, you know, like light sensitive celluloid or whatever. So the threat that we could scoop them up:

    1) Made them launch higher, thus lower res, less payload = less film.

    2) Made them threaten to put a little self destruct mechanism in the satellites, making them waste payload mass (and volume, I suppose)

    Another idea was we'd deploy military sats, and if they didn't work, rather than leaving them up there for the soviets to mess with, or even worse, having them land on soviet territory, we'd just pick em up and take em home.

    The last idea was, of course, being all things to all people all the time, some doofus promised we'd have 100 launches per year, so if we're up there on a .mil mission anyway every 3 days or whatever, why not stick to high res chemical photography for our own sats? Kind of like a mini-orbital unmanned space station.

    So there were very solid cold war reasons to bring back sats.

    You have to realize, all the design work was done in the early 70s, forty years ago. Very few electronic products have forty year runs.
