Operating Reactor Maintenance Effectiveness

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.
