e Surr:y meets the intent of the Generic letter recommendations by maintaining the system operable and having procedures in place to test the overfill protection system.

However, operability and surveillance requirements for the steam generator overfill protection system are not included in the existing Technical Specifications. An enhancement to the Reactor Trip and Engineered Safeguards Actuation Instrument Operating Requirements (Tables 3.7-1, 2, and 3) is currently being completed.

Operability and surveillance requirements for the steam generator overfill protection system will be incorporated into this Technical Specification change. This proposed Technical Specification change is scheduled for submittal in the near future.
