The regulatory objective of the Maintenance Rule, 10 CFR 50.65, is to require licensee monitoring of the overall continuing effectiveness of their maintenance programs to ensure the following:
- Safety-related structures, systems, and components (SSCs) and certain SSCs that are not safety related are capable of performing their intended functions.
- For equipment that is not safety related, failures will not occur that prevent the fulfillment of safety-related functions.
- Failures resulting in scrams and unnecessary actuations of safety-related systems are minimized.
