What are the known technical or regulatory issues with the current version of the Regulatory Guide (RG)? RG 1.133, Revision 1, “Loose-Part Detection Program for Primary System of Light- Water-Cooled Reactors,” published in May 1981, establishes the U.S. Nuclear Regulatory Commission’s (NRC) guidance on loose-part detection program for the primary system of light-water cooled reactors. Section A of the RG references Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Part 36, and several paragraphs that are no longer applicable per the current Standard Technical Specifications. This part of the RG should be corrected in a future revision. Section A of the RG also references Paragraph 20.1(c) of 10 CFR Part 20. The paragraph numbering system in 10 CFR Part 20 has been revised. Subpart part A, Paragraph 20.1003 now provides the definition of as low as reasonably achievable (ALARA). The occupational dose rates are now contained in Subpart C, Section 20.1201. Section C.6 of the RG references Regulatory Guide 1.16 for notification requirements. However, this RG has been withdrawn and this reference needs to be deleted in a future revision. The staff did not identify the need to revise the RG at this time. However, the NRC plans to complete a detailed evaluation of regulatory issues and references to assess their impact on RG 1.133. The NRC will publish a report on this evaluation, including a determination of the future need to revise RG 1.133, in approximately
