Atomic Show #277 – Simon Wakter, pro-nuclear engineer in an ambivalent country

Simon Wakter is a strongly pro-nuclear engineer in a country that passed a referendum officially phasing out nuclear energy since several years before he was born. He has to round up to be called a thirty-something. Simon works in the nuclear energy branch of AFRY, a well-established 17,000 employee, all-of-the-above. engineering company that recently adopted…

Atomic Show #276 – HolosGen Claudio Filippone and Chip Martin

Atomic Show #276 – HolosGen Claudio Filippone and Chip Martin

HolosGen has attacked the nuclear power plant cost and schedule challenge from the opposite direction chosen by many nuclear reactor developers. Claiming to be agnostic about the reactor specifics – as long as it produces reliable heat in a small-enough configuration – HolosGen founder Claudio Filippone decided to focus on radical improvements to the “balance…

X-300 Blazing a Different Kind of Trail in Smaller Nuclear Reactor Development

GEH spent about half a billion dollars designing, testing and certifying the ESBWR. Despite that investment, the 1,520 MWe Enhanced, Simplified Boiling Water Reactor (ESBWR) design documents are just gathering dust with no active projects in sight. GEH is a joint venture between US-based GE, a $95 billion annual revenue conglomerate and Hitachi, a Japanese…

Atomic Show #270 – Fastest Path to Zero

Suzanne (Suzy) Hobbs Baker serves as the Creative Director for Fastest Path to Zero. I recently spoke with Suzy and Steve Aplin, a consultant to the Canadian nuclear industry and frequent Atomic Show guest, about the work that Fastest Path to Zero has done and plans to do in the near future. Fastest Path to…

Atomic Show #268 – Jigar and Jake

Atomic Show #268 – Jigar and Jake

Oklo Power recently announced that it had filed the first non-light water reactor combined license application ever submitted to the Nuclear Regulatory Commission. Their 1.5 MWe fast spectrum, passively safe reactor represents a complete paradigm shift for nuclear energy. It’s not a big, slow to build, hugely expensive project requiring complex financing structures. It’s a…

Oklo has filed first combined license application (COLA) with the NRC since 2009

Oklo has filed first combined license application (COLA) with the NRC since 2009

Oklo, Inc. announced yesterday that its combined license application (COLA) to build and operate an Aurora at INL was undergoing acceptance review at the Nuclear Regulatory Commission. Key project specifics Oklo’s Aurora is a 1.5 MWe liquid metal fast reactor with heat pipes to move fission heat out of the reactor core and into the…

What exploded in Russia on Aug 8? My estimate is a (chemical) booster rocket for a nuclear powered cruise missile.

A cruise missile with a nuclear reactor heated turbofan engine and a liquid fueled booster rocket is the most likely description of the Russian developmental weapons system that exploded while being tested on August 8. It’s likely that the explosion occurred during maintenance or fueling operations on a barge floating off shore and not during…

Project Pele – Part II. Enabling technologies

Project Pele – Part II. Enabling technologies

Building mobile nuclear power plants will be a challenge, but successfully meeting the challenges could alter the future trajectory of the energy and fuels supply industry. That is one of the largest and most consequential sectors of our modern, mobile, industrialized economy. There are no guarantees, but compared to many research and development projects, Project…

Project Dilithium – Boldly going back to a place our ancestors visited and prematurely abandoned

Project Dilithium – Boldly going back to a place our ancestors visited and prematurely abandoned

In January 2019, the Strategic Capabilities Office (SCO) of the U.S. Department of Defense officially informed the world that it was interested in learning more about small, mobile, nuclear generators. The SCO said it wanted to find out if there was technology available that could supply a forward operating base with abundant, emission-free electricity for…

Turning nuclear into a fuel dominated business

Under our current energy paradigm, nuclear power has the reputation of needing enormous up-front capital investments. Once those investments have been made and the plants are complete, the payoff is that they have low recurring fuel costs. Just the opposite is said of simple cycle natural gas fired combustion turbines. They require a small capital…

Fission heated gas turbines address MIT Future of Nuclear challenges. Easier, straighter, less costly path

Addressing Recommendations of MIT Future of Nuclear Energy In a Carbon Constrained World The Massachusetts Institute of Technology (MIT) is a world renowned institution that has produced thousands of highly educated engineers and scientists. It is generously supported by foundations, corporations and governments. In 2003, the MIT Energy Initiative, began publishing a series of reports…

NuScale announces a major step in the NRC’s review of its passively safe SMR

NuScale, a leader in the increasingly competitive field of advanced nuclear reactor design, has announced that the U.S. Nuclear Regulatory Commission (NRC) reviewers issued a document that formally agrees that their design does not require any electrical power to achieve safe shutdown. It’s difficult to explain the importance of that regulatory position. People with experience…
