Which term describes the ongoing monitoring required to verify operability and licensing compliance of an LCO?

• A. Surveillance Requirements
• B. Action Statement
• C. Normal Operating Procedures
• D. Alarm Response Procedures

Answer: (A)

Surveillance requirements are the ongoing checks and tests that prove a system remains operable and continues to meet the licensing conditions for its LCO. They’re built into the technical specifications with defined frequencies and acceptance criteria, so you’re continually verifying performance rather than just testing once. These activities—functional tests, measurements, instrument verifications—ensure that the equipment stays within its required limits and remains in compliance with the license.

Other items describe different roles: an action statement tells operators what to do if the LCO isn’t met, rather than continuously verifying operability; normal operating procedures provide guidance for routine operation; alarm response procedures outline steps to take when alarms occur.
