Service (salt) water system life-cycle management evaluation. Final report
- Stone and Webster Engineering Corp., Boston, MA (United States)
This document provides a description of how the Integrated Plant Assessment for Aging required by 10 CFR Part 54 was tailored at Calvert Cliffs Nuclear Power Plant to a system which had known reliability and availability concerns. This customizing of the requirements of the License Renewal Rule allowed many short term benefits to be gained from the implementation of a regulation normally associated only with extended plant operation. The Important to License Renewal Screening of the Salt Water Cooling System at Calvert Cliffs identified four important to license renewal functions performed by the system. The next step in the Integrated Plant Assessment for Aging would normally be to evaluate whether existing practices at the plant were effectively managing the age-related degradation of the components of the system so that these components could continue to perform the important functions through a license renewal term. In the case of the CCNPP Salt Water System, it was recognized early on that portions of the existing system needed to be replaced with an alternate design due to reliability, availability and maintainability concerns. Therefore, instead of evaluating the existing components for aging as part of the IPA process, it made more sense to determine the most beneficial replacement option for these components and design the new system components with aging management programs in mind. This report describes how the Salt Water System Life Cycle Management Evaluation was conducted, from its inception to the planning stages of implementing its results.
