tified and identified leakage, as well as the basis for and appropriate actions needed for various levels of leakages)i, no specific safety concerns have been identified with RG 1.45. Nonetheless, the staff will continue to monitor operating experience at operating power plants to ensure that its regulatory guidance with regards to reactor coolant pressure boundary integrity, instrumentation, and operational leakage rates remains effective. In particular, the staff intends to monitor experience in implementing RG 1.45 and the below regulatory documents related to reactor coolant pressure boundary leakage. • Inspection Procedure 71111.22, “Surveillance Testing,” particularly section 02.02.b.17. • Enforcement Guidance Memorandum, EGM-09-001, “Dispositioning Violations of NRC Requirements for Operability of Gaseous Monitors for Reactor Coolant System Leakage Detection (ADAMS Accession No. ML090300467) • Technical Specifications Task Force (TSTF) Traveler (TSTF-513), “Revise Operability Requirements and Actions for RCS Leakage Instrumentation,” for Pressurized Water Reactors (PWRs), and TSTF-514 for Boiling Water Reactors (BWRs) • Information Notice (IN) 2005-24, “Nonconservatism in Leakage Detection Sensitivity” (ADAMS Accession No. ML051780073) Enclosure - 2 - 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? Since there are no specific issues identified with RG 1.45, there is no impact on internal or external stakeholders for not updating the RG. 3. What is an estimate of the level of effort needed to address identified issues in terms of full-time equivalent (FTE) and contractor resources? Not applicable. 4. Based on the answers to the questions above, what is the staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise,
