U.K. vision for fusion
The U.K. government has announced a series of initiatives to progress fusion to commercialization, laid out in a fusion strategy policy paper published March 16. A New Energy Revolution: The UK’s Plan for Delivering Fusion Energy begins to describe how the government’s £2.5 billion (about $3.4 billion) investment in fusion research and development over five years will be allocated.

The Criticality Safety Support Group (CSSG) was formed in response to Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 97-2, Continuation of Criticality Safety at Defense Nuclear Facilities in the Department of Energy (DOE) Complex. The CSSG functions as the technical support group to the DOE Nuclear Criticality Safety Program (NCSP) Manager, providing operational and technical expertise pertinent to the criticality safety needs of DOE missions. This expertise is relevant to integral experiments, nuclear data, analytical methods, training, and organizational structures supporting the development and execution of the NCSP. Additionally, the scope of CSSG activities also includes reviewing: • Activities or conditions that have the potential for serious degradation of nuclear criticality safety at DOE facilities • New nuclear facility designs where criticality is a credible hazard • New or revised DOE orders, standards and guides related to criticality safety • Contractor nuclear criticality safety programs at DOE facilities in support of DOE line management Although most CSSG Taskings and Responses are openly available, they are not often discussed in an open forum. This session will include an open discussion of recent CSSG activities to help the nuclear criticality safety community better understand the work and current issues around the DOE Complex.
