Abstract
In this NUREG, the staff of the U.S. Nuclear Regulatory Commission (NRC) discusses the applicable regulations for the inservice testing (IST) of pumps and valves and the examination and testing of dynamic restraints (snubbers) at commercial nuclear power plants. The information in NUREG-1482, “Guidelines for Inservice Testing at Nuclear Power Plants,” Revision 0, issued April 1995, and Revision 1, issued January 2005, has described this topic in the past. This NUREG report replaces Revision 0 and Revision 1 to NUREG-1482 and is applicable, unless stated otherwise, to editions and addenda (up to the 2004 Edition including 2005 and 2006 addendas) to the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code), that are incorporated by reference in which Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(b) incorporates by reference. In addition, the staff discusses other IST program topics such as the NRC process for the review of the OM Code, conditions on the use of the OM Code, interpretations of the OM Code, and development of IST programs for new reactors. In Appendix A to this NUREG, the staff provides guidance included in Revision 1 to NUREG-1482 that has been updated to reflect IST lessons learned and operating experience since issuance of that NUREG. Appendix B contains guidance related to inservice examination and testing of snubbers.
