Reload #7 Proposed Technical Specification Change (MAPLHGR Curve)

Dear Sir:

Pursuant to 10CFR50.90, Boston Edison Company hereby proposes the modifications to Appendix A of Operating License No. DPR-35, which are provided as an attachment to this letter. These proposed modifications are required for our restart from Refueling Outage #7.

The proposed change involves Section 3.ll.A and the figures associated with it. Figure 3.11-7 is added to provide the maximum average planar linear heat generation rate (MAPLHGR) versus planar averagt exposure curves for fuel type BP8DRB300. BP80R8300 is to be used during Reload 7 at Pilgrim in addition to the fuel types currently reflected in curves found in Figures 3.11-1 through 3.11-6. The addition of this fuel to the Pilgrim core requires the addition of this Figure because this fuel type has not been previously licensed to I operate at PNPS.

. Proposed Change The proposed change involves the Pligrim Nuclear Power Station Technical Specifications, Appendix A, Section 3.ll.A and the figures associated with it. Specifically, the proposed changes are to am,end a reference in 3.11.A and add Figure 3.11-7.

Figure 3.11-7 is added to provide the maximum average planar linear heat generation rate (MAPLHGR) versus planar average exposure curves for fuel type BP80RB300. BP8DRB300 is to be used during Reload 7 at-Pilgrim, in addition to

' the fuel types currently reflected in curves found in Figures 3.11-1 through

'3.11-6.

Reason For Change The addition of General Electric BP8DRB300 fuel to the Pilgrim core requires the addition of this Figure because this new fuel type has not been previously licensed to operate at PNPS.

Safety Considerations This amendment request does not present an unreviewed safety question as defined in 10CFR50.59. It has been reviewed and approved by the Operations Review Committee and reviewed by the Nuclear Safety Review and Audit Committee.

Significant Hazards Considerations (1)' Will operation of the facility in accordance with the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Operating Pilgrim Station in accordance with the proposed amendment will not result in a significant increase in the probability or consequences of an accident because the characteristics of type BP8DRB300 fuel is not significantly different from fuel types previously reviewed and approved for use in Pilgrim's core.

Analysis demonstrating this has been performed by General Electric.

The method is contained in NEDE-24011-P-A-7-US of August 1985, which

' was submitted to the NRC September 24, 1985 for review in accordance with the criteria of Section 4 of the Standard Review Plan (NUREG 0800).

The Emergency Core Cooling System models used to determine the effects of a loss of coolant accident (LOCA) in accordance with 10CFR50.46 and Appendix K indicate no increased probability or consequences resulting from installing BP80RB300 fuel into the PNPS core. The results of that analysis did generate a new MAPLHGR curve, represented in Figure 3.11-7, which may be incorporated as an amendment to technical specifications.

Operating Pilgrim in conformance to Figure 3.11-7 results in no significant increase in the probability or consequences of an accident previously evaluated.

(2) Will operation of the facility in accordance with the proposed amendment j~ create-the possibility of a new or different kind of accident from any accident previously evaluated?-

Operating Pilgrim Station in accordance with the proposed amendment will not create the possibility of a new or different kind of

~

accident from any accident previously evaluated because the various analyses performed in accordance with the NRC approved methodologies and computer models identified above indicate that conformance to proposed Figure 3.11-7 is enveloped by previously evaluated accidents.

(3) Will operation of the facility in accordance with the proposed amendment involve a significant reduction in a margin of safety?

Operating Pilgrim Station in accordance with the proposed amendment will not involve a significant reduction in a margin of safety because analyses conducted in accordance with NRC approved methodologies demonstrate that the margin of safety remains substantially unchanged by the incorporation of BP80RB300 into the Pilgrim core. Such incorporation does require the addition of Figure 3.11-7. Operation in accordance with Figure 3.11-7 will ensure that no significant reduction of a safety margin occurs.

For the reasons provided above Boston Edison believes that this proposed amendment does not present a significant hazards consideration.

Schedule of Change This change will be put into effect upon Boston Edison's receipt of NRC approval. Please note that this amendment is needed prior to startup from RF0 #7.

Fee Determination Pursuant to 10CFR170.12, Boston Edison has enclosed a check for $150.00 as an application fee.
