October 4, 1985 RFW-0634 Mr. John Zwolinski, Chief Operating Reactor Branch No. 5 Division of Licensing U.S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Mr. Zwolinski:
Subject:
GPU Nuclear Corporation Oyster Creek Nuclear Generating Station Docket No. 50-219 Environmental Qualification (EQ) of Equipment Important to Safety This letter is a follow-up to our March 27, 1985 and March 30, 1985 letters regarding the equipment environmental qualification status for the Oyster Creek Station.
Our ongoing review of the Oyster Creek EQ program has identified two new temperature elements (TE 40B&C) requiring qualification by Reg. Guide 1.97 and which have already been added to the EQ Equipment Master List (See revised page of Oyster Creek EQ Status - attached). These two temperature elements will be replaced with qualified components by November 30, 1985 as required by 10 CFR 50.49. The attached Justification for Continued Operation OC-85-53, Rev. O provides assurance that failure of the existing temperature elements will not jeopardize plant safety.
This review also resulted in deletion of some components from the EQ Equipment Master List.
In such cases, identification of the deleted devices and justification for their deletion is documented and available in GPUN's Corporate Office.
GPUN reconfirms the mini-outage planning for October,1985 and expects tht, based on the progress being made, all equipment requiring environmental qualification will be qualified by November 30, 1985, barring unforeseen circumstances related to equipment procurement activities. At this time we do not foresee any such problems.
'Very trdly yours, 0510110214 851004

JCO-0C-85-53, Rev. 1 October 1, 1985 Page 2 of 2 COMPONENTS Tag Numbers TE-408, TE-40C Description Containment Spray Temperature Elements OBJECTIVE The objective of this discussion is to determine that the failure of these components will not degrade any safety function nor mislead the operator.
COMPONENT LOCATION Temperature elements TE-40B and TE-40C are located in the northeast and southeast quadrants of the Reactor Building at elevation 23'6" respectively.
COMPONENT FU'NCTION These components provide the operator with indication of the Containment Spray System water temperature.
TE-408 and TE-40C measure the temperature of the water leaving the containment spray heat exchangers.
EVALUATION These temperature elements only provide indication to the operator.
There are no automatic safety actuations associated with these temperature elements.
In addition, the temperature elements are not required to function in order to mitigate a LOCA or HELB either inside or outside containment.
Further, their failure will not degrade the performance of the Containment Spray System.
Finally, since there are no operator actions required in the Emergency Operating Procedures based on these temperature elements readings, the operator will not be misled for those actions required to mitigate the accident.
CONCLUSION Failure of these temperature elements does not degrade the effectiveness of the Containment Spray System to perform its function and would not be misleading to the operator.
