Development of an Ex Situ Performance Testing Protocol for Nuclear Power Plant Flood Penetration Seals
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft NUREG, NUREG-2240, ``Development of an Ex Situ Performance Testing Protocol for Nuclear Power Plant Flood Penetration Seals.'' This draft NUREG summarizes a research project that developed a test protocol for evaluating flood penetration seals using simulated flooding conditions in a laboratory setting.
Changes to Subsequent License Renewal Guidance Documents Regarding Reactor Vessel Internal Components in Pressurized Water Reactors
The U.S. Nuclear Regulatory Commission (NRC) is soliciting public comment on draft interim staff guidance (ISG) that proposes changes to the NRC's subsequent license renewal guidance documents. Specifically, this ISG revises guidance contained in NUREG-2191, ``Generic Aging Lessons Learned for Subsequent License Renewal (GALL- SLR) Report,'' and NUREG-2192, ``Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants.'' NUREG-2191 and NUREG-2192 were published in July 2017 and are not scheduled to be updated for several years. The proposed changes to these documents are contained in a draft ISG entitled, ``Draft SLR-ISG- PWRVI-2020-XX; Updated Aging Management Criteria for Reactor Vessel Internal Components in Pressurized Water Reactors.''
