Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

A high power gyrotron is designed and tested. The design is based on the TE31,8 1 MW gyrotron. The higher power design is realized by choosing TE31,12 higher order oscillation mode. A basic test of the high power gyrotron is performed in JAEA test stand with short pulse and long pulse. In the short pulse experiments, 1020 kW output is confirmed with expected output beam pattern. In the long pulse experiments, it is successfully achieved stable 1 MW operation (1030 kW/2 s). The longest shot is 550 kW/~200 s. These results show successful design and fabrication of the TE31,12 high power gyrotron.
