Memento1979 posted:Expect this to warm up more and more as the Arctic ice cap gets less and less. That area has been subject to amazing amounts of geological scrutiny in the past 3-4 years as Russia comes to realise that with around 4000km of passive margin that has previously been covered in ice on their northern shore, they want to get the data, get drills in place and make the best claim they can to the hydrocarbon resources that are almost certainly there, that Sweden, Norway, Denmark (through Greenland) and Canada will all want as well. Sweden hasn't had territorial waters in the Arctic since 1905.

Both my shoes and clothing checked out when I took them to work to get swabbed, and I'd been wandering around all over the place. However, there is a lot of broken glass. At least take shoes that are good for that.

The first C-5 I saw was after getting diverted to Steward ANGB from Newark Int'l after five landing attempts that had my neighbors thinking that they were going to die. We went to get refueled, and it was all: C-5, C-5, C-5, SAS A330, C-5

Snowdens Secret posted:It's always fun to see the scale of the Iranian centrifuges against, say, American ones. That's because everybody (Americans included) now think that centrifuges that long are nuts. EDIT: Americans got into some really long centrifuges back in the day, because of the higher efficiency of each enrichment stage. However, since centrifuges are AFAIK all vertical, that means higher and higher bottom bearing loads as a trade-off. This leads to higher maintenance, stricter monitoring, and more outages.

grover posted:They don't have to be vertical, as the pull of gravity is inconsequential at the speed they're spinning, but turns out combining vertical orientation with asymmetrical heating creates convection currents that dramatically increases centrifuge efficiency. Why wouldn't a convection current be just as inconsequential as gravity at the RPM's they're operated at?

Snowdens Secret posted:(This also puts the lie to the idea they were ever enriching uranium for civilian powergen purposes, if they couldn't or wouldn't keep fossil-fuel-fired steam turbines up they certainly wouldn't be able to do so with nukes.) Steam turbines for PWRs like Bushehr NPP are considerably less challenging to design and manufacture than steam turbines for modern (i.e. post-WWII) fossil fuel-fired plants.

Snowdens Secret posted:I'm genuinely curious how but I imagine the details are beyond the scope of this thread The big difference is the low inlet steam pressure, ca 70 bar(abs) instead of +140 bar. Also, almost no (relatively speaking) superheating of the steam (heating the steam to a temperature above the boiling point of the current pressure). This means smaller temperature transients between shutdown and operation. The lower temperatures and temperature changes makes design easier from material standpoint. Lubrication, sealing, bearing design also benefit.

TheFluff posted:PWR with heavy water as the moderator. The fuel was unenriched uranium oxide, which theoretically could be mined domestically. In the late 50's/early 60's the nuclear hype was fairly big in Sweden too and the idea was that we should become energy independent by building lots of nuclear reactors that could use our own uranium. There was a rather serious nuclear weapons program too but the entire thing was cancelled in the late 60's for political reasons and while the reactor intended to produce weapons grade plutonium was completed, it was never loaded and started. You're probably refering to Marviken (R4) here, but it was a legitimate reactor design which was planned to be a pre-pilot plant of a domestically designed nuclear fuel cycle (mine -> plant -> reprocessing) without enrichment facilities or imports for commercial power production. The intention to build pure plutonium producing plants had been nixed (public source, holocaust bloopers has made enough opsec violations for this thread) in the 1950's. Ågesta (R3), on the other hand, did absolutely produce weapons grade plutonium (public source), though not much. It was sent back to the US a couple of years ago. quote:The reactor vessel still exists today and has apparently been used for various failure simulations. Ågesta (R3) wasn't the one used for testing containment behavior after a loss of coolant accident. That was Marviken (R4). It is an incredibly well-studied experiment that was basically "hey watch this." (NRC stuff) It's pretty much the only full-size containment experiment we have to validate computer models with (other than Fukushima  ).EDIT: Also, Ågesta is awesome, and I wish they had public tours. All the equipment has the same enamel colour scheme as a 1960's kitchen. Groda fucked around with this message at 22:18 on May 2, 2014 |

This isn't some sort of third-handed retelling of all those plant seeds people irradiated to produce a variety of random-rear end mutations, one of which was improved growth etc.? The amount of radiation at Hiroshima is consistently overestimated in the public mind. The physics package was quite small (64 kg) compared to utility contexts, and the burn-up was something like 1/4 of what fuel in a nuke plant achieves (despite containing a ~100x high concentration of 235U). EDIT: Checked over my figures, and Little Man looked to have reached ~12 MWd/kg U. By comparison, fuel that leaves our reactors is in the 40-60 MWd/kg U range. The point I forgot to make was, the fallout is two things: The fission products (MUST come from a split nucleus) or activation products (nuclei which captured a neutron during the blast). The efficiency was quite low (~15% if you assume 100% 235U in the physics package), and the initial mass was quite small. Additionally, being an airburst, I wouldn't expect extreme levels of activation products in the surroundings, either. Groda fucked around with this message at 20:38 on Aug 3, 2014 |

Snowdens Secret posted:Is that not normal? A power plant has both opportunity and motivation to be as extremely efficient as possible with its fuel usage that a weapon design largely doesn't. Made an edit--basically saying there wasn't that much contamination to go around. However, the city was burned to gently caress, and, having been to Yellowstone a couple of years after the 1988 fire season, I can tell you that might have something to do with it.
