Two steps forward for U.K. advanced nuclear
This week, two significant announcements have emerged from the United Kingdom’s advanced reactor sector.
On June 14, Rolls-Royce, the United Kingdom National Nuclear Laboratory, and the Japan Atomic Energy Agency announced that they had signed two trilateral memorandums of cooperation to collaborate on “advanced modular reactor (AMR) technology, specifically high-temperature gas-cooled reactors (HTGR), and the coated particle fuel these reactors will use.”
Separately, on June 16, Bellevue, Wash.–based TerraPower announced that its Natrium reactor design has been formally submitted for U.K. regulatory review. The company also announced the formation of a new subsidiary, TerraPower UK Ltd.

The U.S. Nuclear Regulatory Commission has recently published a new Regulatory Guide 1.233 that endorses a DOE-industry initiative called the "Licensing Modernization Project" approach for a licensing framework for advanced non-LWR reactors. An NRC-sponsored project has been developing a recommended approach for fitting large external hazards such as large earthquakes and high winds into the LMP framework in a seamless way. This panel session will discuss the technical and regulatory elements of the proposed approach, ongoing work to try out the framework on a few sample problems, and issues with implementing it in a way that designers can use easily.
