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 minimization of active waste from the operation and decommissioning of a fusion power plant is a common goal of fusion development programs in Europe and in the US. Approaches differ, according to national regulations, and include reuse and recycling, clearance for non-active disposal or free-release recycling, and shallow land burial. Adopting the minimization of active waste volume as a design requirement leads to a Low Activation Design if properly optimized for materials choices. Power plant studies, both ARIES in the US and the PPCS in Europe, are adopting strategies to meet such requirements. International collaboration, particularly in the frame of an IEA co-operative program, provides benefits in the development of waste management strategies.
