Joseph M. Farley Nuclear Plant Response to Request for Additional Information Regarding TSTF-432-A, Rev.1 Enclosure 1 Response to NRC RAI

Enclosure 1 to NL-16-0572 Response to NRC RAI NRC RAI As required by section 50.36 of Title 10 of the Code of Federal Regulations (1 0 CFR 50.36), "Technical Specifications," the licensee must provide a summary statement of the bases or reasons for such specifications as part of the LAR submittal. This information may be reviewed for consistency with the associated TS changes. Based on the above, please explain the discrepancies between the TS changes and TS bases that were submitted:

  • The Bases discussion for Required Action 0.1 and 0.2 from TS 3.8.4 still includes a Mode 5 end state reference SNC Response to NRC RAI This sentence in question should have been deleted when FNP submitted to adopt this TSTF Traveler. Enclosure 2 provides the revised TS Bases markup with this sentence deleted. (Please note that it's Required Actions C.1 and C.2 from TS Bases 3.8.4 that contains the erroneous sentence, not Required Actions 0.1 and 0.2.)

DC Sources- Operating B 3.8.4 BASES ACTIONS B.1 and D.1 (continued)

Conditions B and D represent one Auxiliary Building or SWIS DC electrical power subsystem with connection resistance not within the specified limit. Consistent with the guidance in IEEE-450, connection resistance not within the limit is an indication that the affected battery requires attention to restore the resistance to within the limit but is not a basis on which to declare the battery inoperable. Therefore, the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Time allowed to restore the battery connection resistance to within the required limit is a reasonable time considering that variations in connection resistance do not mean the battery is incapable of performing its required safety function, but is an indication that the battery requires maintenance.

C.1 and C.2 If a required SWIS DC electrical power subsystem is inoperable or the connection resistance is not restored to within the limit and the associated Completion Time has expired, the Service Water System train supported by the affected SWIS DC electrical power subsystem must be declared inoperable. The capability of the affected SWIS DC electrical power subsystem to fully support the associated train of Service Water is not assured. Therefore, consistent with the definition of OPERABILITY, the associated train of Service Water must be declared inoperable immediately, thereby limiting operation in this condition to the Completion Time associated with the affected Service Water System train.
