Risk-Informed Decision Making in Generic Safety Issue Resolution and Rulemaking

  • S. D. Weerakkody
Conference paper

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. 1

    GSI-189: “Susceptibility of Ice Condenser and Mark III Containments to Early Failure from Hydrogen Combustion during Severe Accidents.”

     
  2. 2

    GSI-191: “Assessment of Debris Accumulation on PWR Sump Performance.”

     
  3. 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. 4

    Risk-informing circuit analysis.
