Abstract
This paper discusses several major issues the U.S. Nuclear Regulatory Commission (USNRC) has risk-informed in its regulatory actions. The major issues discussed are:
-
1
GSI-189: “Susceptibility of Ice Condenser and Mark III Containments to Early Failure from Hydrogen Combustion during Severe Accidents.”
-
2
GSI-191: “Assessment of Debris Accumulation on PWR Sump Performance.”
-
3
10 CFR 50.48 (c) or NFPA 805 Rule. The NFPA 805 standard is titled “Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants.”
-
4
Risk-informing circuit analysis.
