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 Spinrad three-group theory of the fast effect is formulated. Recipes are presented for determining the necessary cross sections directly from fundamental data and three-group cross sections for various materials are tabulated. A comparison is made between the three-group theory and one-group theory with respect to the calculation of R, the ratio of fast-to-thermal fissions, and it is found that the three-group theory appears to give better agreement with experiments. The three-group values of Є — 1 are about 20% higher than those calculated from the one-group formula.
