RENEWED FACILITY OPERATING LICENSE NPF-30 APPLICATION TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-569, Rev. 2, REVISE RESPONSE TIME TESTING DEFINITION (LDCN 24-0008)
Pursuant to 10 CFR 50.90, Application for amendment of license or construction permit, Ameren Missouri (Union Electric Company) herewith transmits an application for amendment to Facility Operating License Number NPF-30 for the Callaway Plant. Ameren Missouri requests adoption of TSTF-569, Rev. 2, Revise Response Time Testing Definition, which is an approved change to the Standard Technical Specifications for Westinghouse pressurized water reactor nuclear power plants.
The changes proposed per TSTF-569 (Rev. 2) are related to the purpose and past use of several related topical reports, including WCAP-13632-P-A, Revision 2, Elimination of Pressure Sensor Response Time Testing Requirements, and WCAP-l4036-P-A, Elimination ofPeriodic Protection Channel Response Time Tests,2 as applicable to the Callaway Plant. Together, these topical reports justified eliminating response time testing for applicable instrument loops/channels, for all applicable devices/components in the loops/channels, within the Reactor Trip System (RTS) and Engineered Safety Features Actuation System (ESFAS). They provided detailed information that forms the basis for the methodology contained in Attachment 1 to TSTF-569, Rev. 2, which provides a means for allowing use of bounding response times (in lieu ofbeing measured) for newer/redesigned components in the applicable instrument loops/channels. Specifically, adoption of TSTF-569, Rev. 2, is being requested to support plant upgrades to instrumentation subcomponents as they are replaced 1 Refer to Revision 4 ofthe Standard Technical Specifications (STS), Volumes 1 and 2 ofNUREG-1431, Standard Technical Specifications, Westinghouse Plants, 2 Accession No. ML003688411: Application ofWCAP-14036-P-A For Response Time Testing Elimination at Callaway Plant, Unit 1 (TAC No. MA7283) 83 15 County Road 459 Steedman, MO 65077 AmerenMissourLcom
