The Nuclear Power Thread

In summary, the author opposes Germany's plan to phase out nuclear power and argues that the arguements against nuclear power are based primarily on ignorance and emotion. He also argues that nuclear power is a good solution to a number of issues, including air pollution, the waste situation, and the lack of an available alternative fuel. He also notes that the research into nuclear power has been done in the past, and that there are potential solutions to the waste problem.

COVERT TOWNSHIP — Thanks to federal funding announced Wednesday, the Palisades nuclear facility in Michigan is poised to be the first shuttered plant to resume nuclear energy generation. Officials say Palisades, and the energy it produces, will be key to meeting goals for lowering carbon emissions.

The company that owns Palisades Energy LLC, Holtec International, will receive up to a $1.52 billion conditional loan from the U.S. Department of Energy. The funding will allow the 800-megawatt-capacity plant to resume energy production, company officials and U.S. Secretary of Energy Jennifer Granholm said Wednesday morning.

Palisades is a unique PWR that uses cruciform control rods and consequently a unique fuel design to accommodate the control rods which are function between fuel assemblies rather than in particular fuel assemblies.

From ASTM E531.

Neutron Spectrum Calculations – neutron spectrum calculations involve two tasks: (1) determination of the neutron source distribution in the reactor, and (2) transport of the neutron source through the reactor environment to determine the neutron fluence rate distribution at the surveillance location of interest. The specific computational method applied must be validated by comparing results with measurements made on one or more representative benchmark experiments.

Palisades was the first commercial NSSS provided by Combustion Engineering. The CE Nuclear brain trust in those days included a number of Argonne labs luminaries. So I always saw their fingerprints in the almost BWR like aspects of the reactor design.

In any event, it will be interesting to see how the re-licensing process goes. I'm thinking a couple of well-heeled intervenors could really throw a wrench into the works.

I met some of those folks during projects with utilities and CE.

In Europe, more than 70 nuclear reactors have already closed down and it is estimated that dozens more will follow in the coming years. It therefore won't be long before they fall due for dismantling. Recycling and re-using the maximum quantity of materials makes it possible to reduce the ecological footprint of dismantling. And that is what this project is all about: a desire to create a circular economy in dismantling.

Not what I expect when I read the title.

Including Marius Stan, who plated Bogdan in Breaking Bad? Can't get more famous than that.

No, the guys I'm talking about were much earlier. Walter Zinn, Harold Lichtenberger. That era.

In Wyoming, Bill Gates moves ahead with nuclear project aimed at revolutionizing power generation
https://apnews.com/article/bill-gat...-electricity-23176f33200b22b9ede7f4ccf4f2ec3b

Bill Gates and his energy company are starting construction at their Wyoming site for a next-generation nuclear power plant he believes will “revolutionize” how power is generated.

Gates was in the tiny community of Kemmerer Monday to break ground on the project. The co-founder of Microsoft is chairman of TerraPower. The company applied to the Nuclear Regulatory Commission in March for a construction permit for an advanced nuclear reactor that uses sodium, not water, for cooling. If approved, it would operate as a commercial nuclear power plant.

The site is adjacent to PacifiCorp’s Naughton Power Plant, which will stop burning coal in 2026 and natural gas a decade later, the utility said. Nuclear reactors operate without emitting planet-warming greenhouse gases. PacifiCorp plans to get carbon-free power from the reactor and says it is weighing how much nuclear to include in its long-range planning.

In case anyone was wondering, Kemmerer is in western Wyoming, about 50 miles northeast of Salt Lake.
