Advanced Nuclear Reactor

The latter half of May has seen regulatory initiatives benefiting advanced reactors promoted across the government.   The US Nuclear Regulatory Commission (NRC) affirmed new guidance on non-light water reactor (non-LWR) methodologies, and the Department of Energy (DOE) showed support for a new, streamlined emergency preparedness framework for small modular reactors (SMRs) and new reactor technologies. 

Yesterday the US Nuclear Regulatory Commission (NRC) published its proposed rule to revise its Emergency Preparedness (EP) requirements for small modular reactors (SMRs) and other new technologies (ONT, such as advanced reactors). Comments for the proposed rule and accompanying guidance are due on July 27, 2020.

These amendments have been a long time coming,

In time for the Thanksgiving long weekend, we want to draw your attention to a number of interesting reports on advanced reactor developments that have come out over the past couple months:

  • Most recently, the Nuclear Energy Institute (NEI) issued a thoughtful white paper on regulatory and licensing issues for micro-reactors, in advance of the

The Nuclear Regulatory Commission (NRC) held two public meetings on November 15th and 20th to solicit feedback as to whether to compile a Generic Environmental Impact Statement (GEIS) for the construction and operation of advanced reactors. GEISs have the potential to materially reduce the licensing burden on NRC advanced reactor applicants, given that

The Nuclear Innovation Alliance (NIA) late last week published two papers on recommendations for addressing regulatory challenges related to advanced reactor licensing:

The blog authors had the pleasure of

April has seen significant milestones in licensing of advanced reactors.  We take a closer look at these developments, in particular the first submission of an advanced reactor license application in Canada.

On March 20, 2019, Global First Power (GFP), partnered with Ontario Power Generation and Ultra Safe Nuclear Corporation (Ultra Safe), submitted a license application

The U.S. Nuclear Regulatory Commission (NRC) recently released a staff paper-SECY-18-0096-seeking Commission approval of a new proposed methodology for establishing “functional containment” performance criteria for non-light water reactors (non-LWRs).  This methodology would step away from deterministic containment design parameters and embrace a concept of “‘functional containment’ as a barrier, or a set of

On Sunday, the popular TV show Madam Secretary gave a starring role to the climate and security benefits of nuclear power. The episode, titled “Thin Ice,” which is still available on the CBS website, proffered a full-throated defense of the climate benefits of nuclear power, turned a grassroots activist organization into a supporter of

NASA iTech and the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) are collaborating on a unique competition to identify transformational energy technologies that can address critical problems here on Earth that also hold great potential to solve critical technology challenges in future space exploration.  On that list: fission reactors.

NASA and

On April 4, the U.S. Nuclear Regulatory Commission (NRC) issued Regulatory Guide 1.232, Guidance for Developing Principal Design Criteria for Non-Light Water Reactors.  The regulatory guide’s generic set of Advanced Reactor Design Criteria cover most non-light-water technologies. The guide also includes technology-specific criteria for sodium-cooled fast reactors and high temperature gas-cooled reactors.

The regulatory
