NRC’s Inspector General issues report
Overall findings of a survey of Nuclear Regulatory Commission personnel indicate that while the NRC maintains a few strengths compared to external benchmarks, results have declined since 2015 in a number of areas, according to a recent report from the NRC’s Office of the Inspector General (OIG).
The survey was conducted in February 2020 by Willis Towers Watson, a global risk-management, insurance brokerage, and advisory firm that has partnered with the OIG for more than 20 years to assess the NRC’s safety culture and climate, as well as other aspects of employee experience.

The ratio R(D-D)/R(D-3He) of yields of fusion reactions was used as a diagnostic tool for studying the effective ion energy of plasma produced in the 1-MJ plasma focus device at Frascati. The device is operated in the neutron-optimized mode at energies of 250, 390, and 490 kJ. The reaction yields are determined by measuring the activity induced in the 63 Cu(p,n)63 Zn (Ep = 14.6 MeV) and 115 In(n,n')115m In (En = 2.45 MeV) reactions. A detailed discussion of the energy slowing down of neutrons is given and a new calibration of the (p,n) cross section of the monitor reaction is performed. The measurements are carried out simultaneously for the end-on and side-on positions, and no significant differences are observed. A comparison with other experimental data is given. Conversion of the ratio of fusion reaction yields to ion temperatures or effective ion energies of streams interacting with a cold gas medium gives kTt ≅ 14 keV or Ed(kTe = 0.5 keV) = 72 keV, respectively.
