Industry Comments on Draft Regulatory Guide (DG) 1363, Draft Revision 4 to RG 1.105, Setpoints for Safety Related Instrumentation; 85 FR 49685; Docket ID NRC-2020-0171 Project Number: 689 Submitted via regulations.gov
Dear Ms. Jennifer Borges:
The Nuclear Energy Institute (NEI)1, on behalf of its members, submits the following comments on DG-1363, Draft Revision 4 to RG 1.105, Setpoints for Safety Related Instrumentation. We greatly appreciate the effort to revise RG 1.105 by endorsing the ANSI/ISA 67.04.01-2018 Standard without exceptions and appreciate the opportunity to comment on the draft revision. We are considering an industry workshop to ensure practitioners have a better understanding of the RG 1.105 revision and its impact on the maintenance of instrument setpoints. If initial plans for a workshop are developed, we will reach out to the NRC for participation.
Please contact me at sjv@nei.org and (202) 739-8163 if you have any questions or concerns.
Sincerely, Stephen Vaughn 1 The Nuclear Energy Institute (NEI) is responsible for establishing unified policy on behalf of its members relating to matters affecting the nuclear energy industry, including the regulatory aspects of generic operational and technical issues. NEIs members include entities licensed to operate commercial nuclear power plants in the United States, nuclear plant designers, major architect and engineering firms, fuel cycle facilities, nuclear materials licensees, and other organizations involved in the nuclear energy industry.

NEI Comments on DG-1363 1
Affected Section Comment/Basis Recommendation
- 1. Section B.1 ANSI/ISA S67.04-2018 should be ANSI/ISA S67.04.01-2018 Change ANSI/ISA S67.04-2018 to ANSI/ISA S67.04.01-2018.
- 2. Section B.2.1 First sentence. The term anticipated conditions is not commonly used and causes confusion. The term accident conditions is a more appropriate term because any of the non-normal conditions are not anticipated.
Change the term anticipated conditions with accident conditions. Consider other events that would rely on safety-related systems and/or components (e.g., Anticipated Operational Occurrences (AOOs)).
- 3. Section B.2.2.1 Paragraph 3 reaffirms the NRC staffs approval of Option B of TSTF-493, Revision 4 but there is no mention throughout the DG-1363 of Option A of TSTF-493, Revision 4.
State that Option A of TSTF-493 is still a viable path.
- 4. Section B.2.2.3 This section refers to drift as though is mentioned in the footnote under 4.6 of the standard; however the footnote in the standard only mentions test acceptance criteria and TLU.
Clarify the language to address the inconsistency.
- 5. Section B.2.2.5 The term (Performance Acceptance Criteria) should be (Performance Test Acceptance Criteria)
Change the term (Performance Acceptance Criteria) to (Performance Test Acceptance Criteria).
