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…

Recently, the Hill has been taking a flurry of legislative actions that impact the advanced reactor community across all spectra.  We provide a summary of some of the major bills going through Congress below, including a couple which have recently become law or may become so soon.

Nuclear Energy Innovation Capabilities Act (NEICA) (S. 97).…

A bipartisan group of nine U.S. senators has introduced the Nuclear Energy Leadership Act (NELA) (S 3422), a bill designed to help the United States return to its lead in nuclear energy technology.  The bill sponsors explain that the U.S. has yielded this position to Russia and China–weakening our energy security, economic competitiveness, and national…

This month, the NRC published an early draft regulatory guide on the content of license applications for non-LWRs.  The document is designed to help license applicants apply the NRC’s movement towards a risk-informed/performance-based regulatory approach towards the drafting of an actual license application.

The document is in part the result of the Southern Company-led Licensing …

The NRC staff recently publicly released a major new paper embracing regulatory reform to advance risk-informed regulation for advanced reactors.  Included in this paper is a concept of a “10 CFR Part 53”—a potentially entirely new process for licensing advanced reactors.

SECY-18-0060, “Achieving Modern Risk-Informed Regulation,” proposes “several significant and specific revisions” to the…

A recent headline in the energy trade press would not likely have caught the attention of the advanced nuclear industry: “Trump’s DOE punishes Obama-era solar success story.” A casual reader might quickly dismiss the story as indicative of a Trump Administration bias against renewable energy. The details reported in the story, however, convey a far…

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…

The U.S. Department of Energy (DOE) this week announced the award of approximately $60 million to 13 advanced reactor projects—the first under the funding opportunity announcement (FOA) “U.S. Industry Opportunities for Advanced Nuclear Technology Development.”  The 13 projects cover a diversity of steps in the commercialization process:

  • 4 concern modeling and development pathways;

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…
