COLUMBIA GENERATING STATION LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION RAt 2.2-01
Background:
License renewal application (LRA) Section 2.1.1 states in part, "Consistent with NEI 95-10, the Columbia license renewal project scoping process establishes a listing of plant systems and structures, determines the functions they perform, and then determines which functions meet anyone or more of the three criteria of 10 CFR 54.4{a)."
Issue:
The following Updated Final Safety Analysis Report (UFSAR) systems could not be located in LRA Table 2.2-1, Table 2.2-2 or Table 2.2-3.
FSAR Section System 8.3.1.1.4, 120/208-Volt Non-Class 1E 120/208-Volt Non-Class 1E Instrumentation Instrumentation Power System Power System 9.1.4 Fuel Handling System Fuel Handling System
..... ~.~ Plant Lighting System Plant Lighting System 11.2 through 11.4 Radwaste Systems (Liquid, Gaseous & Solid) 11.6 Post Accident Sampling System Post Accident Sampling System Request:
Provide additional information to describe how the above systems were scoped for license renewal.
RAt 2.3.3-01
Background:
License renewal rule 10 CFR 54.21(a)(1) states, "For those systems, structures, and components within the scope of this part, as delineated in § 54.4, identify and list those structures and components subject to an aging management review." The staff reviews the full extent of the license renewal scoping boundary, along with the information contained in the LRA and other sources of plant-specific information to confirm that all component types subject to an aging management review (AMR) have been identified.
