Dear Sir:

Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 NUREG 0737, Item Il.K.3.14 NUREG 0737, item II.K.3.14 specifies a design change to the isolation condenser system isolation logic. The description as provided in the NUREG is incorrect for the Oyster Creek station. The isolation condenser system utilized at the Oyster Creek Nuclear facility door, not isolate upon a high-radiation signal in the main steam line leading to the isolation condensers.
Tne Oyster system utilizes excessive flow in the steam lines to and condensate lines from the isolation condensers as the only isolation signal for the system isolation valves.
Because the Oyster Creek system is different from the one described in'the NUREG, we feel no additional modifications are required to meet the objective of this NUREG ltem.
I f you should have any questions concerning this matter, p. ease call Mr.
James Knubel (201-455-8753).
Very truly yours, bll L/
