Regulatory Guide; Issuance, Availability

The Nuclear Regulatory Commission (NRC) has issued a new guide in its Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques used by the staff in its review of applications for permits and licenses, and data needed by the NRC staff in its review of applications for permits and licenses.

Regulatory Guide 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities,” is being issued for trial use. Regulatory Guide 1.200 is being developed to provide guidance to licensees in determining the technical adequacy of a probabilistic risk analysis used in a risk-informed, integrated decision-making process.

Standard Review Plan Chapter 19.1, “Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities,” has been developed for the NRC staff to use in conjunction with Regulatory Guide 1.200.
