Dear Ms. Adensam:

PARTIAL FEEDWATER HEATING HOPE CREEK GENERATING STATION DOCKET NO. 50-354 Public Service Electric and Gas Company (PSE&G) requests that License Condition 2.C.12, " Partial Feedvater Heating",

be moaified. At present this license condition does not affect the ability of PSE&G to safely operate the facility under its low-power license and Technical Specifications.

Thus, no amendment of the present low-power license is being sought. We request that this change be incorporated into the full power license for the Hope Creek Generating Station. This license condition currently reads as follows:

"PSE&G shall not operate the facility (other than for normal start-up or shutdown) with the feedwater inlet temperature less than 424.5 F."

We request that this license condition read as follows in the full-power license:

"The facility shall not be operated with partial fcedwater heating for the purpose of extending the normal fuel cycle without prior written consent of the staff."

This request is made because feedwater temperature varies with the operating power level. At a rated steam flow of 105%, the feedwater inlet design temperature is 424.5'F.

At 100% rated steam flow, the feedwater inlet design temperature is 419.7 F (Process Flow Diagram Heat Balance & Legend, M-0900-0). Feedwater temperature continues to drop with decreasing power level while all feedwater heaters are

/g)bl in service. The effect of this license condition as written ( 9 8605130246 860508 PDR ADOCK 05000354 P PDR

,J

Director of Nuclear 2 5-8-86 Reactor Regulation is to preclude operation at reduced power levels for extended periods. For example, if the reactor was continuously operating at 75% rated power, the process heat balance predicts an inlet feedwater temperature of 397.9 F (M-0900-0).

To meet the license condition as stated, PSE&G would have to declare the plant to be in the normal start-up or shutdown mode, which is not a true statement. This does not meet the intent of the license condition, which is to prohibit fuel cycle extension by partial feedwater heating without written approval of the staff.

The requested modified license condition does not set any new precedents as it is already listed in the operating licenses of River Bend, Susquehanna 2, Grand Gulf I, and Limerick 1 power plants, among others.

If you have any questions in regard to this matter, please do not hesitate to contact us.

Sincerely, L _ _g C D.H. Wagner USNRC Licensing Project Manager R.W. Borchardt USNRC Senior Resident Inspector
