History and promise of high temperature gas cooled reactors

By: Diarmuid Foley A small modular nuclear reactor to replace coal plants could be on the market within 5 years. In 2014, the Generation IV international forum[1] confirmed the Very High Temperature Reactor (VHTR) as one of 6 promising reactor technologies that should be pursued in order to develop advanced reactors suitable for deployment in…

NuScale Getting Ready For Design Certification Submission

NuScale remains on track to submit a high quality design certification application to the Nuclear Regulatory Commission by the end of 2016. That statement might surprise people who follow small modular reactor developments closely enough to be aware that the company received a status report earlier this week from the NRC that gave a grade…

No obstacles prevent China from rapidly building floating nuclear power plants

No obstacles prevent China from rapidly building floating nuclear power plants

Credible entities in China have begun lining up the supply chains required to produce reliable electrical power from barge mounted nuclear fission power plants. There are no technical, industrial, or regulatory hurdles that prevents the first of those machines from being in service by 2020. China has a pressing need for the electricity those movable…

Bechtel will “pursue” accelerated mPower development

I’ve relearned a valuable lesson — read press releases and other PR material closely, paying special attention to wiggle words. On Friday, March 4, Bechtel issued a press release titled Bechtel, BWXT to Pursue Acceleration of Small Modular Nuclear Reactor Project. In my excitement, I missed the key word in the headline and in the…

Bechtel and BWXT have announced an acceleration of Generation mPower

Note: For an update on this topic see subsequent post titled Bechtel will “pursue” acceleration of mPower project. On March 4, 2016, in a press release issued from Reston, VA, Bechtel and BWX Technologies (BWXT) announced that they would be accelerating their Generation mPower small modular reactor project. Bechtel will take over the project lead…

DOE and UAMPS sign agreement for siting at INL

At the 12th annual Platts Nuclear Energy Conference, John Kotek, the Acting Assistant Secretary of Energy for Nuclear Energy just made a major announcement. Yesterday, February 17, 2016 Rick Provencher and Doug Hunter signed an agreement between the U.S. Department of Energy and UAMPS (Utah Associated Municipal Power Systems). It provides UAMPS with a use…

Treasure trove of documents about the ML-1, the US Army’s trailer-mounted, nitrogen-cooled, atomic fission-heated generator

I recently published an article featuring a video from the Army Nuclear Power Program that focused on the Army’s mobile, low power closed cycle nitrogen cooled nuclear reactor designated the ML-1. The article generated a good discussion that indicated a strong desire for more information about the program. My initial searches didn’t turn up a…

X-Energy introduced its company and first product to Virginia chapter of ANS

On Tuesday, October 27, three leaders from X-Energy spoke to the Virginia ANS chapter about their company and the Xe-100, the high temperature, pebble bed gas reactor power system that they are designing. During the presentation, meeting attendees learned that X-Energy is an early phase start-up with a total staff of a few dozen people,…

SMRs – lots of noise but DOE budget that’s 1% of annual wind tax credit

I’ve been spending some time watching, rewatching and clipping interesting excerpts from the Senate Appropriations Energy and Water subcommittee hearings on the FY2016 Department of Energy budget. It’s not everyone’s idea of entertainment, but it’s fascinating to me to watch publicly accessible discussions about how our government makes decisions, sets priorities and spends the money…

Tour of NuScale control room and test facility

Tour of NuScale control room and test facility

Disclosure: I have a small contract to provide NuScale with advice and energy market information. That work represents less than 5% of my income for 2014. On October 20, 2014, I had the opportunity to visit NuScale’s facilities in Corvallis, OR. Though the company now has offices in three cities, Corvallis, the home of Oregon…
