Columbia additional request for additional information: Exigent license amendment request to extend Technical Specification 3.8.7, Distribution Systems - Operating, completion time (EPID: L-2020-LLA-0181)

By letter dated August 20, 2020 (Agencywide Documents Access and Management System (ADAMS)

Accession number ML20233A976), Energy Northwest (the licensee) requested a license amendment to revise the Columbia Generating Station Technical Specification (TS) 3.8.7, Distribution Systems -

Operating. This license amendment request (LAR) would add a one-time extension of the Completion Time (CT) of TS Action 3.8.7.A, from 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />, specifically associated with Division 2 Alternating Current (AC) electrical power distribution inoperability caused by inoperability of Division 2, 120/240V Power Panel E-PP-8AE during repairs on its supply transformer E-TR-8A/1. The NRC staff has reviewed the LAR and determined that additional information is required to complete the review. The NRC staff issued request for additional information (RAIs) on August 22, 2020, and August 26, 2020. The NRC staffs additional RAI is listed below. The staff may have additional RAIs. The staff held an RAI clarification call with Energy Northwest on August 31, 2020. The Energy Northwest staff requested, and NRC agreed, to a RAI response by September 1, 2020.

The NRC staff considers that timely responses to RAIs help ensure sufficient time is available for staff review and contribute toward the NRCs goal of efficient and effective use of staff resources. Please note that if you do not respond to this request by the agreed-upon date or provide an acceptable alternate date, we may deny your application for amendment under the provisions of Title 10 of the Code of Federal Regulations, Section 2.108. If circumstances result in the need to revise the agreed upon response date, please contact me at (301) 415-3168 or via e-mail Samson.Lee@nrc.gov.

RAI No. 8 Based on the proposed Technical Specification (TS) changes, the TS 3.8.7.A will have two Notes:

NOTES

1. Until October 1, 2020, a Completion Time of 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> is applicable for replacement of E-TR-8A/1.

[Note 2 is from a previous amendment]

The licensee has not provided the justifications from both deterministic and risk perspectives if the above Completion Times (CTs) are entered at the same time.

Please either provide requisite justifications if both CTs are entered at the same time or suitably revise the TS Notes so the two CTs cannot be entered at the same time.
