Plant-Specific, Risk-Informed Decisionmaking: Inservice Testing
The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 1 to Regulatory Guide (RG) 1.175, "Plant-Specific, Risk- Informed Decisionmaking: Inservice Testing." This RG has been revised to incorporate additional information since Revision 0 was issued, particularly information to be consistent with the terminology and defense-in-depth philosophy provided in RG 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis," as well as to endorse a standard by the American Society of Mechanical Engineers Boiler and Pressure Vessel Code for Operations and Maintenance.
