U.K., Japan to extend decommissioning partnership
The U.K.’s Sellafield Ltd. and Japan’s Tokyo Electric Power Company have pledge to continue to work together for up to an additional 10 years, extending a cooperative agreement begun in 2014 following the 2011 tsunami that resulted in the irreparable damage of TEPCO’s Fukushima Daiichi plant.

Neutron emission spectra from targets bombarded by 14-MeV neutrons have been calculated using three nuclear models. The elements studied included aluminum, iron, copper, nickel, and niobium and were selected because of their potential importance in fusion reactor design and because measured cross sections and evaluated cross-section libraries were available for comparison with the calculations. Contributions from statistical, pre-equilibrium, and direct reactions are included to achieve a good fit to the data. The calculated spectra are also compared with the predictions of the ENDF/B-IV and the Livermore ENDL neutron libraries.
