A few days ago, Dan Yurman at Neutron Bytes published a blog post that is now titled Flash: NuScale executive says firm may build SMRs at Idaho lab. It was a follow-up to an earlier post in which Dan speculated about the Idaho National Lab’s potential as a good site for a new nuclear power […]
Small Nuclear Power Plants
The Canadians are coming
Hugh MacDiarmid, the Chairman of the Board for Terrestrial Energy, Inc., gave a talk to the Economic Club of Canada on September 24, 2014. That talk included a brief description of TEI’s integral molten salt reactor technology, but most of the talk was visionary in nature and aimed at exciting his Canadian audience about the […]
HTR-PM – Nuclear-heated gas producing superheated steam
The first HTR-PM (High Temperature Reactor – Pebble Module), one of the more intriguing nuclear plant designs, is currently under construction on the coast of the Shidao Bay near Weihai, China. This system uses evolutionary engineering design principles that give it a high probability of success, assuming that the developers and financial supporters maintain their […]
Fission is an elegant way to heat a gas
What if it was possible to combine the low capital cost, reliability, and responsive operations of simple cycle combustion gas turbines with the low fuel cost and zero-emission capability of an actinide (uranium, thorium, or plutonium) fuel source? Machines like that could disrupt a few business models while giving the world’s economy a powerful new […]
SMRs – Why Not Now? Then When?
I have shamelessly borrowed the title of one of the talks given during the first day of the Nuclear Energy Insider 4th Annual Small Modular Reactor (SMR) Conference as being representative of both the rest of the agenda and the conversations that I had in the hallways during the breaks. For the past five years, […]
SUNY Maritime Student Advocates Commercial Nuclear Ship Propulsion
Stimulated by early atomic optimism, naval successes and Eisenhower’s Atoms for Peace initiative, four nations built ocean going ships with nuclear propulsion plants. The US built the NS Savannah, Germany built the Otto Hahn, Japan built the Mutsu, and Russia built a series of nuclear powered icebreakers. For reasons that are beyond the scope of […]
NEI Small Reactor Forum Report – Part 2
The Nuclear Energy Institute (NEI) hosted its biannual Small Reactor Forum on February 25, 2014. The agenda for the one day event included six well-organized sessions with presentations from three small reactor vendors, the industry trade group, the regulatory agency, and several outside observers with a significant interest in the technology from a variety of […]

Argentina pours nuclear grade concrete for CAREM, a 25 MWe SMR
On February 8, 2014, Argentina poured its first nuclear grade concrete for CAREM-25, an integrated pressurized water reactor (iPWR) whose design has been in intermittent progress for more than 24 years. Will Davis wrote an informative piece titled Argentina carries torch for SMR construction about the design and the project at ANS Nuclear Cafe. Argentina […]
Westinghouse’s Roderick shifts resources from SMR to AP1000
NuScale was the sole winner in the latest round under the DOE’s Funding Opportunity Announcement (FOA) for small modular reactors (SMR). The DOE announced its decision in December 2013. As a result of that decision, Westinghouse has shifted internal resources from working on a 225 MWe SMR to focus more on continued refinements and completion […]
NuScale wins second round of DOE SMR funding under FOA
On December 12, 2013, the US Department of Energy (DOE) announced the selection of NuScale as the winner of the second round of funding under the Department of Energy Funding Opportunity Announcement (FOA). That announcement, which had been due since sometime in September, must have been quite welcome to a lot of really talented and […]
Root cause of Naval Reactors policy of strict secrecy about nuclear propulsion plant design
As a Navy nuke, I was carefully taught to believe that everything we learned about atomic energy had to be strictly protected from release to anyone who was not “cleared”, especially anyone who was not a US citizen. I started to question that policy after I completed my tour as the Engineer Officer on the […]
