History Made as NuScale Files First SMR Application With U.S. Nuke Regulators

Two years ago, NuScale committed to filing a license application for its eponymous SMR design with U.S. regulators by the end of 2016. Just three months before two company executives used a custom pen on the cover letter of the ~12,000 page design certification application, even NuScale insiders were doubtful that the task could be…

Terrestrial Energy Announces Plans To License Their Integral Molten Reactor In The U.S.

Yesterday, Terrestrial Energy USA (TEUSA) informed the U.S. Nuclear Regulatory Commission (NRC) that they planned to begin pre-license application discussions with a goal of being ready to file a design certification application no later than Oct 2019. Here is a brief video that provides an overview of Terrestrial Energy‘s Integral Molten Salt Reactor (IMSRTM TEUSA…

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…

Will China convert existing coal plants to nuclear using HTR-PM reactors?

It would be a huge benefit to the earth’s atmosphere if China, India, Brazil and the US could reduce direct coal burning while still making use of much of the capital that they have invested in building coal fired power plants. It would make an even larger difference in reducing air pollution in the areas…

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…

How Did the MOX Project Get So Expensive?

Over the past week or so, I’ve engaged in a “root cause analysis” project to determine why the US is having so much difficulty implementing a plan to take 34 metric tons of nearly pure plutonium 239 — a fissile isotope with virtually the same energy value as uranium 235 — out of our nuclear…

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…

Lightbridge metallic alloy fuel provides upgrade path for LWRs

Lightbridge metallic alloy fuel provides upgrade path for LWRs

Lightbridge, a company that was originally incorporated as Thorium Power, Inc., has achieved significant technology developments after making a strategic turn in 2010 from thorium based fuels to low enriched uranium metal alloy fuels. As funding dried up from the government agencies supporting their thorium work, the company chose to use its assembled nuclear engineering…

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…

U-Battery – Micronuclear power with intriguing business model

U-Battery was one of the more intriguing presenters at the Advanced Reactor Technical Summit (ARTSIII) held at the Oak Ridge National Laboratory last week. Even though this was a technical summit, the segments of the presentation that captured my attention were the business model and the funding source. However, certain technical choices are vital to…
