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.
Nuclear Criticality Safety Division Topical Meeting (NCSD 2022)

Wednesday, June 15, 2022|8:00–9:45AM PDT|Laguna A
Session Chairs:
Kaushik Banerjee (PNNL)
Justin B. Clarity (PNNL)
Session Organizer:
In this panel session, each panelist will discuss their country-specific approach to post-closure criticality safety in view of the final geological disposal of spent nuclear fuel and high-level radioactive waste. The discussion will include and reflect key topics presently being considered by the new international, waste management organization (WMO)-level collaboration initiative on post-closure criticality safety under the IGD-TP framework (https://igdtp.eu/). Each speaker will give a 10-minute summary with a Q&A afterwards.
