Re: Seaborg MSR: liquid moderator

There is also recent patent application for this Seaborg MSR design, with a description of the moderator fluid (hydroxide), published by the World Intellectual Property Organization in December 2018:

Seaborg MSR: liquid moderator

Reading through the IAEA SMR Book (see below, p. 201-204) I came across the Seaborg MSR design. Seaborg is a Danish company which has presented an innovative MSR design in the sense that their reactor design makes use of a liquid moderator (proprietary and patent pending), instead of graphite, makin...

Re: Belgium nuclear developments

Not a very smart decision to replace nuclear power plants with natural gas fired power plants, if you deem CO2 emissions important, as Belgium and the EU (based in Brussels) do. Belgium once generated 60% of its electricity with the help of its nuclear power plants. It also has to do with a failure ...

Re: Transatomic Power has published a technical white paper

Is the winding down of Transatomic Power also not a tacit admission that the unique selling point of their MSR design, the zirconium hydride moderator, is basically unworkable ?

Re: Monju FBR decommissioning

Like pretty much every other country, Japan made sodium-fast-breeders, operating on the U-Pu cycle, the centerpiece of its plan for how to deal with the considerable wastes from PWRs and BWRs. They were trying to execute the "two-phase" plan I refer to in this article. And it has failed. They need ...

Re: Hitachi to build ABWs in the UK

Ha Ha Ha The Government is desperate to avoid the appearance of state ownership of anything, because if they admit that state ownership is not evil, the Overton window will shift drastically in Corbyn's favour. They spent all their time attacking him for wanting state ownership - they can't be seen...

First new reactor of any kind in the United States in 40 yrs

Yes, it's tiny, but still it's the first new reactor of any kind in the United States in 40 years, according to LANL/NASA:

Re: Polish nuclear - and a market for GenIV nuclear?

Europe has banned Russian nuclear plants and some have been discontinued in an advanced construction stage. The West European nuclear industry is in a bad state. German companies have discontinued nuclear due to domestic ban on all nuclear. Areva has broken up after getting in trouble all over. The...

Re: Westinghouse eVinci Micro Reactor

This Westinghouse eVinci reactor is somewhat akin to the concepual MegaPower reactor which is being developed by Los Alamos National Laboratory (LANL), judging from the words 'monolith' and heat pipes. The LANL MegaPower reactor apparently uses commercial grade LEU-UO2 fuel pellets, according to the...

Re: Westinghouse eVinci Micro Reactor

Interesting. It seems that more and more companies are busy with developing micro-reactors. One such example is the Swedish company LeadCold (https://www.leadcold.com) which is developing a 3 to 10MWe lead-cooled fast reactor, with a focus to supplant diesel generators in the Canadian Arctic. It als...

Canadian pressure tube SCWR

Canada is part of the Generation IV consortium. Its main nuclear lab, CNL (former AECL), is focusing on developing a supercritical water reactor which uses pressure tubes (1200MWe in power), building upon its experience and its familiarity with CANDUs. The CNL Nuclear Review dedicated a whole issue ...

Canadian private equity firm Brookfield buys Westinghouse (or what remains of it):

Bad news IMO, private equity means stuffing a company with debt and milking a company's cash flow to the max.

Re: France plans to close up to 17 reactors by 2025

Reality has set in in France regarding nuclear power: the goal to cut the share of nuclear power to 50% and close up to 17 reactors by 2025, is unattainable. It's "too brutal and unrealistic" according to the French environment minister Nicolas Hulot: http://www.france24.com/en/20171107-france-hulot...
