SUBJECT:

RE-REVIEW OF GRAND GULF TECHNICAL SPECIFICATIONS As requested by your memorandum dated February 27, 1984 we have re-reviewed the following sections of the Grand Gulf Technical Specifications, including j

the applicable bases section, which are in the Power Systems Branch (PSB) l areas of, primary responsibility.

The Technical Specificatters as written do not include the surveillance requirements for the turbint overspeed protection system.

It is our understanding that these Technical Specification requirements were ina dverten ti,5 deleted frca the original Grand Gulf Technical Specifications Centact:

a March 8,1984 E

Roger J. Mattson l issued in June, 1982.

Therefore, we require that these Technical Specifications be reinstated into the Plant Technical Specifications.

Because of the unique-ness of the Grand Gulf Turbine Generator system, the wording of the turbine overspeed protection system surveillance requirements should be the same as the Commanche Peak turbine overspeed surveillance requirements which has the same type of turbine generator system.

Based on our review, we conclude that the Grand Gulf Technical Specifications are acceptable except as noted above and in the attached marked up sectiodof the Technical Specification.

Enclosed are copies of those specifications which have been marked with the appropriate corrections to bring them into l

conformance with the 5,tandard Tec,hnical Specification and the FSAR.
