s Sir:
Reference No. 3 transmitted a revised page 509:2, for replacement in the Facility Hazard Sur:: mary Report (FHSR) for the Yankee Atomic Electric Plant at Rowe, Massachusetts.
The revised page incorporated surveillance requirement for portions of the Safety Injection System, reference No. 1.
l In our preparation of the revision, we inadventently used a draft page prepared for submittal to the AEC some years ago. The draft, however, was never formally submitted. We are including with this Supplement a new page 509:2, based on the current page dated 9/15/59, and revised to include the l
surveillance requirement for portions of the safety injection system.
1 We trust you will find this information satisfactory; however, should l
you desire additional information, feel free to contact us.
Respectfully submitted, YANKEE ATOMIC ELECTRIC COMPANY 44k k.

All red scran tests will be nada during scheduled reactor shutdcwn er during varicus energency shutdcwns.
Safety Injectien Systen - Weekly, during pcwer cperatien, all of the punps and valves of the safety injecticn systen will be operated individ-ually frcu the safety injecticn centrol panel in the centrol reca to determine their serviceability and correct light positien indicaticn. The punps will be operated cnly en by-pass to the safety injectien-shield tank cavity water stcr-Loop fill valves will only be opened with the injection valve closed age tenk.All locked-cpen and Iceked-closed valves cutside the vapor centainer tight.
