SUMMARY

OF THE AUGUST 11, 2021, CATEGORY 2 PUBLIC MEETING HELD TO DISCUSS PROPOSED REVISION 5 TO REGULATORY GUIDE 1.9, "APPLICATION AND TESTING OF SAFETY-RELATED DIESEL GENERATORS IN NUCLEAR POWER PLANTS On August 11, 2021, the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Reactor Regulation (NRR) and Office of Nuclear Regulatory Research (RES), staff met with representatives from the Nuclear Energy Institute (NEI), Institute of Electrical and Electronics Engineers (IEEE), Electric Power Research Institute, licensees, and other members of the public. The meeting was held to discuss and provide additional clarification on submitted comments during the solicited public comment period, which closed on February 18, 2021 (86 FR 5267) in regard to the staff's proposed changes to Regulatory Guide 1.9, Revision 5, "Application and Testing of Safety-Related Diesel Generators in Nuclear Power Plants.

The meeting followed an agenda provided by the NRC staff that posted on July 29, 2021 meeting notice, found in Agencywide Document Access Management System (ADAMS)

Accession Number ML21223A163. The NRC staff provided a presentation ADAMS Accession Number ML21221A191) summarizing the proposed changes to Regulatory Guide 1.9, Revision 5, addressing the following sections:

• Section 2, "Background," "Onsite Emergency Alternating Current Power Sources," last paragraph addressing mission time of the emergency diesel generators (EDGs).

• "Staff Position 2," Section C-2, o Section 2.1, Testing environmental parameters o Section 2.3a and 2.3b, Operation of the EDG in parallel

• "Staff Position 3," Section C-3, o Section 3.8a and 3.8b, Operation of the EDG in parallel CONTACTS: Liliana Ramadan, NRR/DEX Stanley Gardocki, RES/DE 301-415-2463 301-415-1067

J. Johnston, et. Al Afterwards, NEI presented its concerns and recommendations for the specific issues it identified during the public comment period. NEIs presentation can be found in ADAMS Accession Number ML21223A100.

After the NEI presentation, the meeting was open for additional comments and questions from the public and NRC staff. Comments were made regarding the scope of IEEE Standards from other participants. No regulatory decisions were made at the meeting.
