Dear Mr. O'Reilly:
Subject:
Oyster Creek Station Docket No. 50-219 Response to DRO Bulletin No. 74-16 In DRO Bulletin No. 74-16 dated December 13, 1974, you alerted us to the possibility of having improperly machined pistons in Colt Industries (Fairbanks-Morse) diesel-generators.
At our Oyster Creek Nuclear Generating Station, we presently utilize two different types of diesel engines. The emergency diesel-generators were manufactured by the Electro-Motive Division of General Motors Corporation, LaGrange, Illinois.
The fire diesel engines were manufactured by Cummins Engine Company, Inc.,
Columbus, Indiana.
Since these engines are not of the type described in your bulletin, no further action is planned on our part.
V ry truly yours, Donald A. Ross Manager, Generating Stations-Nuclear cs 9604230306 960213 PDR FOIA f

-J-(c) The torus fatigue characteristics when subjected to forces resulting from opening of relief valves.
(d) The predicted maximum number of relief valve openings, i.
singly and collectively, during plant life.
(c) Surveillance requirements, including frequency of inspections, for verification of torus structural integrity.
2.
For the steam quenching vibration phenomenon, operating procedures should be developed, and changes to the Technical Specifications should be proposed to preclude the development of elevated temperatures of the torus pool water and provide for inspection of the torus as appropriate to identify any damage in the event of an extended relief valve operation.
In this effort, consider the results of your review required by Regulatory OperationsBulletin 74-14, "BWR Relief Valve Discharge to Suppression Pool", dated November 11, 1974, and the interim recommendations of the General Electric Company to BWR owners (References 4 and 5).
3.
Submit a description of your program and.your proposed changes to the Technical Specifications.
A suggested review schedule with major milestones and dates is enclosed for your consideration; if these dates are not satisfactory, adjustments may be possible af ter discussion with us.
If you do not intend to initiate a program for verification j
of the torus and/or proposed surveillance requirements, we require that you submit appropriate justification.
Your submittals are requested in accordance with the proposed schedule.
Three signed and notarized originals and thirty-seven (37) copies of your submittals are needed for our review.
Sincer~ly, e
