Dear F!r. Crutchfield:

With respect to your correspondence of June 12, 1981 concerning SEP Topic IX-3 " Station Service and Cooling Water Systems." The Oyster Creek facility differs from your assessment in that the Turbine Building Closed Cooling Water System uses hydra::ine rather than chromate as a rust inhibitor and make-up to the system is manually provided rather than automatically.

In addition, the control rod drive pumps thrust bearing and gear box coolers are not cooled by the Reactor Building Closed Water System as conveyed in Amendment No. 42 to the provisional operating license.

We anticipate that the subject SEP Topic will be re-evaluated as other SEP topics identify additional cooling water systems that are important to safety.

If additional information is required, please contact bir. J. Knubel at (201) 299-2264 Very truly yours,

//
