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.

Deuterium-tritium fusion neutrons, peaked at 14.1 MeV, can activate the materials employed in a fusion reactor. The radioactivation characteristics and level of activation that occurs in a fusion reactor after shutdown depend on the elements that are activated, the neutron wall loading, the duration of the exposure, and the neutron flux spectrum present. The radioactivity resulting from potential elements considered in fusion reactor designs is discussed. The dominating radionuclides and the levels of activation resulting from exposure of these elements to the neutron flux spectrum in the first-wall region of a typical Li20 solid-breeder fusion reactor blanket are also given.
