SUMMARY
OF DECEMBER 8, 2022, PUBLIC MEETING WITH DUKE ENERGY CAROLINAS, LLC, REGARDING PRE-APPLICATION MEETING TO DISCUSS THE PROPOSED LICENSE AMENDMENT REQUEST TO REVISE TS 3.7.11 CONTROL ROOM AREA CHILLED WATER SYTEM (CRACWS)
(EPID L-2022-LRM-0086)
On December 8, 2022, an Observation public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Duke Energy Carolinas, LLC (Duke Energy, the licensee). The purpose of the meeting was for Duke Energy to discuss a proposed license amendment request (LAR), for Catawba Nuclear Station, Units 1 and 2, to revise Technical Specification (TS) 3.7.11, Control Room Area Chilled Water System (CRACWS).
The meeting notice and agenda, dated October 25, 2022, are available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML22298A092. The licensees presentation is available in ML22336A038. A list of the meeting attendees is provided as an enclosure to this letter.
Background
The CRACWS provides cooling water to the air handling units that provide air temperature control to the control room, control room area, and essential switchgear rooms. If both CRACWS trains are inoperable, TS 3.7.11 currently requires Unit 1 and Unit 2 to enter Limiting Condition for Operation (LCO) 3.0.3, which requires a shutdown of both units. The licensee is proposing to allow 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to restore one train to operable if both trains are inoperable. The presentation included an overview of the CRACWS system, the design bases, the proposed TS changes, the proposed mitigating actions, and the planned site modifications to be put in place to allow operation for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with both trains of CRACWS inoperable.
Discussion During the teleconference, Duke Energy followed the presentation.
The NRC staff discussed the following issues:
Given that the proposed control room temperature limit is <80 degrees Fahrenheit (°F) and the control room upper bound limit is 90°F, upon reaching the 80°F limit, the NRC questioned if there is a need to include a discussion if the control room will heatup beyond the 90°F upper bound during the time it takes to
shutdown both units (LCO 3.0.3 requires shutdown to Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />).
Actions for structures, systems and components (SSCs) for any potential impact to control room and essential switchgear rooms for equipment above 90°F.
Consideration of the design bases, TS, and impact on the safety-related SSCs, including the essential switchgear, that will be affected by two inoperable CRACWS for a 24-hour period.
Any CRACWS modifications that will be credited, such as defense-in-depth, mitigating actions, and compensatory measures.
The licensee stated they will provide similar technical justification and level of detail in the June 30, 2017, Byron Station and Braidwood Station application (ML17181A276). The NRC staff noted that there may be differences between the precedent and Catawba and suggested that the LAR should reflect their own licensing basis and site specific design.
Consider including the proposed TS bases change pages, for information only.
No members of the public were in attendance.
No regulatory decisions or commitments were made during the meeting.
