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.

Recent fusion reactor conceptual designs include pressurized water as the coolant for the first wall and blanket. To determine design adequacy, the consequences of a pressurized water cooling tube failure within the blanket have been analyzed using the time-dependent computer code ATHENA. The ATHENA code, being developed by EG&G Idaho, Inc., simulates safety related transients in fusion blankets, first walls, and other reactor systems. The analysis showed that some blanket design modifications must be made to ensure module integrity following an internal cooling tube break.
