i like nuclear power and thers like lots of uranium in the sea and its not hard to centrifuge the uranium out because its so heavy and also u can make fresh water from the salt water and irrigate the planet

Can I say I like this pro-science bender you've been on

Also imagine if we manufactured our fossil fuels out of seawater during the slack time of a reactor's operation (11 pm 6 am) We could also just take the carbon out of the sea water and use it elsewhere

Nuclear power: it's the poo poo

Dude's right, aside from Thresher there's literally no record of even a minor nuclear accident happening in the US Navy. They are really drat good at nuclear power. For that matter, if you exclude the Soviets/Russians the safety record in Naval projects generally is fantastic

I was at a Democratic platform meeting last night and this older lady used her speaking time to rant about nuclear power. Then she got back in line, waited patiently, and gave another three minute anti-nuclear rant. I don't get how someone can be pro-science and anti-nuclear at the same time.

You know how conservatives kinda believe in stuff just for reactionary/historical reasons? (Like for example wind and solar are bad because liberals like it)

that's not a very subtle cross there

"The whole airplane has to be dragged into a specially constructed hanger/hot room, where the reactor has to be removed by remote control, and placed in a pool. Meanwhile, the nose is on the other side of several feet of lead and concrete, and the squidgy organic bits can deplane in relative safety. The actual plane itself would have to have a 'massive' amount of shielding, which is just the thing aeronautical engineers like to hear. The people who made this design study still figured this would not be enough to protect the crew against significant radiation exposure, and figured that training flights would be kept to a minimum, and restricted to low power at that. The crew would undertake one actual mission on a full power profile - and then they would have received the maximum safe lifetime exposure to radiation, and would never fly the atomic hate needle ever again."

1950s Life: Military not giving up on the whole 'atomic airplane' idea

You have to admire their perseverance, I suppose.



The main debate among the brains of the time was "should we modify an existing airframe or design a new one?" The main concern was of course a atomic plane gap with the Soviets.



This concept is interesting, though like the last atomic atomic bomber we've seen, it places special emphasis on putting the crew far away from the reactor, which tells me even 1950s engineers were not so confidant about the the whole 'lightweight radiation shield' problem.



The atomic powered early warning aircraft makes sense, assuming you could build it big enough so that the crew isn't forced to live in Type VII U-boat squalor in a tiny shielded compartment at the front for weeks at a time. I'm not seeing the advantages of a nuclear powered B-57, though :/



Launching ICBMs from a nuclear powered airplane is, ah, interesting. You guys have been talking about servicing the past few pages - imagine the service bulletins that thing would generate. It has *twin* reactors, and carries something like 2 Titan IIs fueled on its wings, in the upper atmosphere, during all weathers. The "low level supersonic ramjet bomber" is probably actually less problematic from a maintenance standpoint, since I think Ramjets don't need moving parts. I also can't imagine it'd be more dangerous to its crews than the B-58. Then again, the accidents would probably be memorable in a way that a supersonic bomber merely exploding and crashing with a thermonuclear bomb on board positively dull.



Given how the 1950s rolled with Health and Safety, I think we should be glad it never happened.

from a biological angle it's kind of doubtful anything with a DNA repair scheme much more elaborate than our own would have ever had the spare energy to get big brains and flexible niche behaviors the way we have. DNA repair is an energy-intensive process, and the one we have is really drat good for the few resources it requires. single mutations are handled by a backup copy, and double-mutations that corrupt both copies can be repaired through end-joining. it could be more effective a couple of ways, but all those ways require either some really serious glucose and lipid input (and therefore hurt our chances to survive mundane famine) or some really funky chemistry that makes our homeostasis a lot easier to shock. naked mole rats basically went the former route, but the extra energy they put into hostile environment survival left relatively little left over for brain size. brains are insanely energy hungry.

prly doesn't matter in the long run, CRISPR will likely allow you to back up an idealized version of your DNA and allow you to undergo an IV treatment forcing it back into your body like a memetic virus in 30 years or something

OK this is hilarious:

The state of Georgia wanted to build two new nuclear reactors at a nuclear complex known as "Vogtle". South Carolina also wanted two new nuke plants. In 2007 construction of these plants started, with figurative nuclear giant Westinghouse dreaming of build all four plants as "modules" greatly reducing construction costs. The contractors for this are Toshiba, which bought Westinghouse (the company that popularized AC electricity!!) and another construction firm named Chicago Bridge & Iron Co . With energy prices spiking and worries about global warming, there was a shitload of federal cash to subsidize this project. These next generation plants were going to be more efficient and use interchangeable parts, driving down costs. It was supposed to be start of a atomic power renaissance

It is now 2017. The plants are half finished and billions overbudget. Georgia has been "pre-billing" its customers to pay for the expansion for years, and will presumably continue to do so after the project is done. Westinghouse has declared bankruptcy. Toshiba is taking billions in losses.

there are reasons for this

  • Some sort of Louisiana swamp magnate bought the company that used to do lots of nuclear plants, Stone & Webster Inc. They of course were just a hollow shell of what they once were, having no plants to construct for the past 30 years.
  • Swamp magnate manages to use the name of Stone and Webster to land a shitton of construction contracts
  • Big surprise, Swamp magnate sucks at building nuclear reactors, as does Stone & Webster, having in essence forgotten how to do it
  • Swamp thing sells his construction company to Chicago Bridge & Iron Co. for 3.3 billion in 2012
  • Three years later, Chicago Bridge & Iron Co. sells swamp thing construction company to Westinghouse/Toshiba for 230 million
  • Apparently even this was too much, and Toshiba accused Chicago Bridge of inflating the value of swamp thing construction by 2 billion or so
  • Sues, court case, renegotiation, etc
  • Meanwhile, all sorts of new regulations get thrown up, complicating construction
  • and constant mistakes in construction mean expensive things are done wrong and have to be redone
  • Westinghouse takes on all the liabilities all these delays cause, something it extremely regrets and these penalties and debts drive it into bankruptcy
  • MOAR pure comedy: the price of electricity has declined quite a bit thanks to the 2008 + economic catasterfuck so these costs will have to be absorbed over a much longer time period

TL,DR: People tried building a bunch of nuke plants and it turned out very poorly, suddenly people are all like "renewables, eh?"
