Subject s ~ License Amendment Application to Revise the Post-Accident Monitoring Specification Tables 3.3-10 and 4.3-10 and Refueling Operations Instrementation Specification (TAC Number M75236) v Gentlemen:
The enclosed application requests that the Davis-Besse Nuclear Power Station (DBNPS), Unit Number 1 Operating License, Appendix A, Technical Specifications be revised to' reflect the changes attached. The proposed changes involve Technical Specification (TS) 3/4.3.3.6, Post-Accident Instrumentation, Table 3.3-10, Post-Accident Monitoring Instrumentation, Table.4.3-10, Post-Accident Monitoring Instrumentation Surveillance Requirements, and TS 3/4.9.2,
. Refueling Operations-Instrumentation.
The DBNPS has been using the excore neutron flux monitors supplied with'the
' Babcock and Wilcox (B&V) nuclear instrumentation system to meet both TS 3/4.9.2 and TS 3/4.3.1.1,. Reactor Protection System Instrumentation, Table
,3.3-1 and 4.3-1, Item 11 (Source Range, Neutron Flux and Rate - Startup and Shutdown). However, the B&W-supplied nuclear instrumentation system is not environmentally qualified.
Two excore neutron. flux monitors qualified to meet the requirements of Regulatory Guide 1.97, " Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess Plant and Environs Conditions During and Following an Accident", were installed during the fifth refueling outage at the DBNPS and vill be available to be used to comply with
\\.
TS 3/4.3.3.6 following the sixth refueling outage and also with TS 3/4.9.2
)-
during the sixth refueling outage. This request proposes the addition of
" neutron flux (vide range)" and " neutron flux (source range)" to Tables 3.3-10 and 4.3-10 to reflect the appropriate surveillance requirements for the new monitors for demonstrating operability.
Additionally this request proposes TS 3/4.9.2 be changed to require calibration of the neutron flux monitors prior to entry into Mode 6 in order to allow either the new monitors or the existing s~, u ", ".ity g,t,o be,u, sed to comply with this specification.
