US Congress Passes Bill To Help Advanced Nuclear Power (arstechnica.com) 333
An anonymous reader quotes a report from Ars Technica: Last week, the House passed a bipartisan bill that originated in the Senate called the Nuclear Energy Innovation Capabilities Act (S. 97), which will allow the private sector to partner with U.S. National Laboratories to vet advanced nuclear technologies. The bill also directs the Department of Energy (DOE) to lay the ground work for establishing "a versatile, reactor-based fast neutron source." The Senate also introduced a second bill called the Nuclear Energy Leadership Act (S. 3422) last Thursday, which would direct the DOE to actually establish that fast neutron reactor. That bill also directs the DOE to "make available high-assay, low-enriched uranium" for research purposes. The Nuclear Energy Leadership Act has not yet made it past a Senate vote. The report also mentions a recent U.S. Court of Appeals ruling to keep older reactors online. "The court said that subsidies for nuclear energy proposed by Illinois don't cause any interference with federal control over interstate power markets, which is prohibited," reports Ars.
"In 2017 the state of Illinois agreed to offer a Zero Emissions Credit that included nuclear energy (PDF). The credit was opposed by fossil fuel generators and by the Electric Power Supply Association, who sued the director of the Illinois Power Agency. But the Federal Energy Regulatory Commission (FERC) and the Department of Justice filed a joint brief in the case several months ago, saying those federal agencies had no problem with Illinois' credit system, according to Utility Dive."

Nice try, but France standardised reactor designs massivly driving down const of construction. Insurance is not as insane. ... stupid... arse backwards.... I'm trying to find words for the American process of insuring any risk but really the english languge doesn't quite have the necessary expressiveness. Decommissioning in general is only an issue if you expect on doing so.

Lifetime emissions of a nuclear plant are around 100g/kWh. Better than coal but considerably worse than wind/solar+battery.
Every once in a while I see a citation and a fact that challenges what I know. I follow the source. 9 times out of 10 the "fact" is a misleading representation of the citation. This is one of those misleading representations. The document has a table that provides the assessed minimum/median/maximum carbon emissions for a power source. This table gives following values for nuclear (in gCO2eq/kWh):
minimum: 3.7
median: 12
maximum: 110
Suffice it to say that the parent post, by approximately citing the maximum number, is quite misleading.
In comparison, here are a few other sources (in terms of min/median/max gCO2eq/kWh):
Nuclear: 3.7/12/110
Coal: 740/820/910
Gas (Combined Cycle): 410/490/650
Geothermal: 6.0/38/79
Hydropower: 1.0/24/2200
Concentrated Solar Power: 8.8/27/63
Solar PV—utility: 18/48/180
Wind onshore: 7.0/11/56
Based on these numbers (purely considering lifetime CO2 emissions--from your source), nuclear appears to be pretty competitive with wind/solar, etc.
Please help keep /. factual. Mod parent down or this post up. Thank you.

France at the moment produces 68% of its electricity with nukes. ...
The rest is mostly renewables. They are replacing nukes constantly with renewables.
And the electricity price is low, because the state is subsidizing it
If you ever had been in France, you would know that ;D

"Actually work"? You mean like Windscale, TMI, Tchernobyl, Fuckushima? Yes, all cheap to clean up, nobody injured, and who cares about the waste that stays dangerous for millions of years. On top of that, the TCO of nuclear (if nothing blows up and you disregard the waste problem) makes it one of the most expensive ways to generate electricity.

"You mean like Windscale"
All someone has to do to prove they don't care about actually generating power is say something like that.
Power generation tech to be viable has to have one of two characteristics. It either has to provide power when you say so, or it has to never stop. Solar and wind have neither of those properties.

Zero. If Joe Blow iron worker slips and falls to his death while working on a wind turbine, that's an industrial accident. Not a failure of wind power. Same as if Joe Blow is replacing an aircraft warning light on the side of a nuclear cooling tower and falls to his death, that's an industrial accident, not a failure of nuclear power.

Hmm, as of 2008, rooftop solar has caused 0.44 deaths per TWh produced. Nuclear is at 0.04 deaths per TWh.
Now, Fukushima has happened since then, so we should probably add the one (1) extra death (NOT per TWh) that happened as a result of Fukushima recently (saw it in the news last week or so). So, ~4500 TWh nuclear, one death, increases nuclear deathrate to 0.0402 per TWh.
Hmm, So, rooftop solar causes 11 times as many deaths as nuclear, even if you include TMI, Chernobyl, and Fukushima.
Well, we all know that nuclear is by far the most deadly form of power ever invented, so obviously, these numbers are fabrications....
Oh, and note for the "but, but, radioactive waste for BILLIONS of years!!!", it should be noted that the short half-life stuff that makes nuclear waste, well, seriously radioactive is pretty much gone a week after shutdown of the plant.
Medium half-life stuff will be useful for a few centuries (yes, useful - it's actually possible to extract usable power from that crap).
And the long half-life stuff? Not nearly so dangerous as airplane flight. When I was in the Navy, I got more dosage flying back and forth between the USA and Holy Loch than I got from spending a couple months in the engineering spaces of a nuke boat between flights....

As your parent pointed out: this is completely irrelevant.
And no one believes such numbers anyway ... during construction of a nuclear plant on average about 10 people die. Hundreds died in Australia due to open pit mining of uranium ore ... no idea where that pushes the numbers.

Solar power has caused ZERO deaths per Wh. Industrial accidents relating to solar installations have happened but the actual act of making solar power has literally zero deaths unless you can find some random guy that somehow got electrocuted. Nuclear energy undeniably has a body count attached to it. A low body count to be sure but the number is not zero. Construction accidents have happened with every form of power generation. Furthermore solar has not rendered any location permanently uninhabitable

It's been something like 40 years since Jimmy Carter stopped this dead.
Carter stopped fuel reprocessing in relation to breeder nuclear reactors and a plutonium economy. All the new MSR type reactors this bill is targeting are burner type reactors, that much is written into the bill.
The thing that you are referring to was re-implemented by Reagan. Carter wasn't stupid, Reagan was dumb.

Is looking more like the cultures in Biblical times that were very wealthy, powerful, influential, and very deadly to outsiders.. and then suddenly they fell due to mass deaths caused by disease, droughts, mass crop infestations, etc.
In this case, it will be caused by monocultures, mass sterilization of plants and animals, nuclear disasters, and the spread of technology. The spread of television (and possibly cellphones and internet) lowers birth rates more successfully than promotion of condoms, eugenicists should know that by now.

It was in the summary: "a versatile, reactor-based fast neutron source [wikipedia.org]". Depending on the reaction chosen, the resulting waste could have a half-life as short as 100 years.
Then there's fusion power, which has virtually zero waste products. But that's still under research.

The current fusion reactors leave behind a huge pile of radioactive waste: the reactor.
Perhaps we might evolve to "neutron less" fusion reactors after we get the "simple ones" running, but except for space fare ... it makes no sense. Wind and Solar and Biomass and perhaps oil from algae is much much much cheaper.
