NRC Requests Comments on New Regulatory Guide for Assessing, Monitoring, and Mitigating Aging Effects on Electrical Equipment

(View Federal Register Notice (FRN), DG-1393)

Stakeholders have until March 7, 2022 to comment on DG-1393, “Assessing, Monitoring, and Mitigating Aging Effects on Electrical Equipment Used in Nuclear Power Generating Stations.”  This proposed new Regulatory Guide endorses IEEE Std. 1205-2014 to constitute an acceptable method for use in satisfying the Commission’s regulations with respect to maintenance and aging management of applicable SSCs subject to aging stressors, aging mechanisms, and aging effects to ensure facility safety throughout the period of initial license operation, extended operation, and subsequent extended operation.  The staff believes that efficiency and effectiveness will be enhanced as there would be a common guidance document as the technical basis for maintenance practices and aging management of the subject systems, structures and components (SSCs) for license applications and other interactions with the NRC. In addition, this new RG would reduce the need for the NRC staff to request additional information from licensees and applicants where such information is rendered unnecessary by the new guide.
