RE:
Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 Final Report on Location of Governor Lube Oil Cooler /
Standby Diesel Generator
[RDC 45(82)]
Dear Mr. Keppler:
This letter serves as a final report pursuant to 10CFR50.55(e) concerning the governor lube oil coolers on the standby diesel generators supplied by Trans-america Delaval.
Initial notification relative to this report was made to Mr. John Streeter of your office by Mr. Emanuel Riley of The Cleveland Electric Illuminating Company (CEI) on January 14, 1982.
This report includes a description of the deficiency, an analysis of the safety implication, and the corrective action taken.
Description of Deficiency Transamerica Delaval is supplying four (4) diesel generator units (Model DSRV16) for the Perry Nuclear Power Plant (PNPP) for use as a safety-related standby power source. The engine governor and governor lube oil cooler were manuf actured by the Woodward Governor Company of Fort Collins, Colorado, and were installed and piped on the engine by Transamerica Delavel.
The potential defect exists in the mounting location of the governor lube oil cooler.
If the lube oil cooler is installed above (elevation) the oil level indicator of the governor, the possibility exists that air might become trapped in the system when the oil level in the governor is low.

Analysis of Safety Implications If. air is trupped in the governor's oil system, engine starting, and thus standby electric power availability, may be affected.
Design Criterion 17 of Appendix A to 10CFR50 and Section 8.3.1.1.4 of the PNPP PSAR require an available standby power supply to provide for safe shutdown of the reactor and to maintain the plant in a safe condition.
Corrective Action Initial notification of this potential defect was submitted to CEI by Trans-america Delaval in a letter dated December 18,'1981.
Upon receiptoof this-notification, a visual inspection of all four (4) engines was conducted by Perry Project personnel along with a Transamerica Delaval technical repre-sentative. This inspection verified that the lube oil cooler was mounted on the turbocharger support bracket, above the governor oil level indicator.
Nonconformance Report PiS 0002 was then issued to control modification.
Information supplied by Transamerica Delaval states that moving the governor lube oil cooler.to a location below the governor oil level indicator will eliminate this deficiency. Transamerica Delaval has been notified of the existance of this deficiency at PNPP and will supply mounting instructions and materials (tubing).
The relocation of the cooler will take place during engine assembly under the direction of a Transamerica Delaval service ro.presentative.
Completion of this modification is presently scheduled for July 1,1982.
