OF APRIL 11, 2024, PUBLIC MEETING WITH CONSTELLATION ENERGY GENERATION, LLC REGARDING PROPOSED ALTERNATIVE TO IMPLEMENT AMERICAN SOCIETY OF MECHANICAL ENGINEERS OPERATION AND MAINTENANCE CODE CASE OMN-32 (EPID L-2024-LRM-0050)
On April 11, 2024, a public meeting via webinar was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Constellation Energy Generation, LLC (Constellation). The purpose of the meeting was to discuss a potential fleet request to use American Society of Mechanical Engineers ( ASME) Operation and Maintenance (OM) Code Case OMN-32, Alternative Requirements for Range and Accuracy of Pressure, Flow, and Differential Pressure Instruments Usen in Pump Tests for Braidwood Station, Units 1 and 2; Byron Station, Units 1 and 2; Calvert Cliffs Nuclear Power Plant, Units 1 and 2; Clinton Power Station, Unit 1; Dresden Nuclear Power Station, Units 2 and 3; James A. FitzPatrick Nuclear Power Plant; LaSalle County Station, Units 1 and 2; Limerick Generating Station, Units 1 and 2; Nine Mile Point Nuclear Station, Units 1 and 2; Peach Bottom Atomic Power Station, Units 2 and 3; Quad Cities Nuclear Power Station, Units 1 and 2; and R.E. Ginna Nuclear Power Plant. The meeting notice and agenda, dated March 28, 2024, are available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML24101A222. The presentation material used by the licensee during the meeting is available at ML24100A767. A list of attendees is enclosed.
During the meeting, Constellation presented information regarding the planned alternative.
Constellation discussed the following topics as part of its presentation:
Alternative:
Constellation discussed the type of alternative that they plan to submit which will be pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.55(a)(z),
Alternatives to codes and standards requirements, to utilize ASME OM Code Case OMN-32. ASME OM Code Case OMN-32 provides alternative testing instrument accuracy and range requirements for flow, pressure, and differential pressure instruments used to Group A, B, comprehensive, and preservice pump tests. ASME OM
Code Case OMN-32 is not applicable for instruments measuring speed and vibration and will continue to meet the existing instrument accuracy and range requirements in ASME OM Code. Constellation stated that ASME OM Code Case OMN-32 would be an alternative for all pumps in the inservice testing (IST) program at each of Constellations 21 units. Constellation stated that implementation of ASME OM Code Case OMN-32 would allow sites to utilize permanently installed plant instrumentation to support pump testing which would eliminate the need to install temporary instruments reducing dose and person-hours.
Constellation stated that the most recent IST program plan will be submitted for each plant in the submittal to specify pumps within the scope of the request for each plant.
Submittal and Precedent:
Constellation stated that they are targeting submittal by the end of April 2024 with a plan to request approval in 1 year from the date of submittal. Constellation stated that the submittal will be the first in the industry for an alternative to utilize ASME OM Code Case OMN-32.
The NRC staff provided feedback on the following topics:
Constellation should include all the applicable NRC-approved alternative requests related to the pumps accuracy requirements within the scope of the request for each plant.
ASME OM Code Case OMN-32 is not accepted in Regulatory Guide 1.192, Operation and Maintenance Code Case Acceptability, ASME OM Code (ML21181A223), yet so the licensee will need to justify as plant-specific alternative for each applicable plant.
Constellation should review the applicable ASME OM Code edition for each plant for differences in accuracy requirements, and pump testing requirements (such as baseline and periodic pump verification testing).
The statement that analytical methods will be used is outside the scope of ASME OM Code Case OMN-32 because, when the NRC staff submitted a comment proposing that the proposed Code Case be revised to include this approach, ASME stated that such a change would require a new ballot. Therefore, the use of analytical methods is a deviation from ASME OM Code Case OMN-32 and should be justified separately from the justification for the use of the ASME OM Code Case OMN-32 approach.
The submittal should specify that the speed and vibration accuracy requirements in the ASME OM Code continue to apply regardless of proposed alternatives.
The submittal should specify 10 CFR 50.55a(z)(1) alternative request rather than relief request under 10 CFR 50.55a(f).
No regulatory decisions were made during the meeting. No members of the public were in attendance. No comments or questions from the public were received during the meeting.
