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.

Simplified cost-scaling relationships are employed to identify the key economic drivers for fusion power systems. These economic drivers are examined in the context of compact reactor design trends. On the basis of this examination, four areas are identified as being critical paths in the development of compact designs. Two areas are physics in nature and concept dependent. These are the scaling dependence of energy confinement and the limitations on beta. Two areas are technological in nature and generic. These are the development of first-wall materials capable of operating at high wall loading (>5 MW/m2) and with useful lifetimes (∼1 yr) and maintenance approaches compatible with high availability and first-wall replacement times of ∼1 yr.
