Impact of Construction (Under a Combined License) of New Nuclear Power Plant Units on Operating Units at Multi-Unit Sites

摘要

The U.S. Nuclear Regulatory Commission (NRC) staff is issuing its Final Interim Staff Guidance (ISG) COL-ISG-022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML112630044). The purpose of this ISG is to provide staff guidance for assessing combined license (COL) applicant compliance with the requirements of Title 10 of the Code of Federal Regulations, (10 CFR) 52.79(a)(31). This regulation requires applicants for a COL intending to construct and operate new nuclear power plants (NPPs) on multi-unit sites to provide an evaluation of the potential hazards to structures, systems, and components (SSCs) important to safety for the operating units resulting from construction activities.
