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

November 3, 2015 By Rod Adams 11 Comments

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

October 30, 2015 By Rod Adams 48 Comments

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, […]

Using portable nuclear generators to break petroleum logistical dependence circa 1963

October 27, 2015 By Rod Adams

Note: The initial version of this post was written based on an incorrect interpretation of the Roman numeral date stamp at the end of the video. The film was made in 1963, not 1968. The post was revised after a commenter provided the correct production date. End note. I have a theory about why the […]

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

March 29, 2015 By Rod Adams

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 […]

Elite international experts to debate SMRs’ role in nuclear co-generation and hybrid systems

February 3, 2015 By Rod Adams

Atomic Insights is a media partner for the 5th Annual Small Modular Reactor Summit, scheduled for April 14-15 in Charlotte, NC. Conference value increases when information about the event reaches people who are keenly interested in the topics that will be discussed. We will be running several pieces that will help Atomic Insights readers decide […]

Tour of NuScale control room and test facility

October 24, 2014 By Rod Adams

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 […]

UAMPS stepping forward to serve customers

October 19, 2014 By Rod Adams

The established nuclear energy industry has taken a wait-and-see approach to the idea of developing and deploying smaller, simpler fission power stations that can take advantage of the economy of series production. The industry’s trade organization, the Nuclear Energy Institute, has expressed cautious optimism and has engaged in a moderate effort to identify regulatory obstacles […]

Prospective customers lining up at NuScale

October 16, 2014 By Rod Adams

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 […]

The Canadians are coming

October 4, 2014 By Rod Adams

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

June 27, 2014 By Rod Adams

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

June 26, 2014 By Rod Adams

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?

April 1, 2014 By Rod Adams

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, […]
