Dear Mr. Denton:
As stated in section 7.7 of Supplement No. 1 to the Shoreham Safety Evaluation Report (SER) the Long Island Lighting Company had committed to conduct a review to demonstrate that failures or malfunctions of power sources or sensors providing power or signals to two or more control systems will not result in conse-quences outside the bounds of the FSAR Chapter 15 analyses or beyond the capability of operators or safety systems.
In fulfillment of this commitment, LILCO, via the reference (1) letter, had forwarded a report entitled " Control System Failures Evaluation Report".
Per the reference (2) letter, the staff conducted a preliminary review of this report and determined that, while the report appeared to satisfactorily address the effects of power supply failures, it did not address control system failures caused by common sensors such as hydraulic headers and impulse lines.
LILCO subsequently performed and completed an evaluation of control system failures caused by common hydraulic headers or common impulse lines.
As stated in Ref. 3, this evaluation concluded that these failures will not result in consequences outside the bounds of the FSAR Chapter 15 analyses or beyond S
