Document Control Desk Page two The enclosed program document describes the basis for the Turbine Maintenance and..
Testing Program-for Seabrook Station Unit 1. - This program encompasses periodic tests and inspections to preclude generation of turbine missiles as a result of material defects or turbine overspeed.
Inspection and testing intervals are based on the Seabrook Station Updated Final Safety Analysis Report (Section 10.2), the Seabrool Station Unit 1 Safet)-
Evaluation Report and the manufacturer's recommendations referenced in the program document.
As New llampshire Yankee acquires more operating exper'e.nce combined with industry experience and technological changes the maintenance program may-be revised. Changes to the program will be reviewed and approved by the Station Manager and the_ Executive Director Nuclear Production. A summary report of inspections aerformed in accorc'ance with thic program will be completed following each refueling outage and will be a_vailable for NRC review. The enclosed turbine maintenance program document completes NilY's commitment to submit its turbine maintenance progrr.m within three years of obtaining-an operating license.
