Nuclear Regulatory Commission November 3, 2022 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Renewed Facility Operating License No. DPR- 51, issued to Entergy Operations, Inc., for operation of Arkansas Nuclear One, Unit 1 (ANO-1). The proposed amendment would revise the dose equivalent Iodine (I)-131 and the reactor coolant system (RCS) primary activity limits required by ANO-1 Technical Specification (TS) 3.4.12, ``RCS Specific Activity,'' and the primary-to-secondary leak rate limit provided in TS 3.4.13, ``RCS Operational LEAKAGE.'' For this amendment request, the NRC proposes to determine that it involves no significant hazards consideration. Because this amendment request contains sensitive unclassified non- safeguards information (SUNSI), an order imposes procedures to obtain access to SUNSI for contention preparation.

The U.S. Nuclear Regulatory Commission (NRC) is issuing a new Regulatory Guide (RG) 1.246, ``Acceptability of ASME Code, Section XI, Division 2, `Requirements for Reliability and Integrity Management (RIM) Programs for Nuclear Power Plants,' for Non-Light Water Reactors.'' This RG describes an approach that is acceptable to the NRC staff for the development and implementation of a preservice inspection (PSI) and inservice inspection (ISI) program for non-light water reactors (non-LWRs). It endorses, with conditions, the 2019 Edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (ASME Code), Section XI, ``Rules for Inservice Inspection of Nuclear Power Plant Components,'' Division 2, for non-LWR applications. This RG also describes a method that applicants can use to incorporate PSI and ISI programs into a licensing basis.
