Dear Mr. Stolz:

Under separate cover, we are transmitting three (3) original and forty (40) conformed copies of an application for Amendment to Facility Operating License No. NPF-3 for the Davis-Besse Nuclear Power Station Unit No. 1.

This application requests that the Davis-Besse Nuclear Power Station Unit 1 Technical Specifications, Appendix A, be revised to reflect the change attached. The proposed change involves:

Technical Specifications figures 3.1-2a and 3.1-3a of Cycle 3 Reload Report BAW-1707 (Figure 8-5 and 8-10 of the report).

The attachment identifies the proposed change and its safety evaluation.

The proposed change is in reference to our previous submittal to the NRC (Serial No. 787 dated March 5, 1982) which enclosed the reload report (BAW-1707) for operation of Cycle 3 at the Davis-Besse Nuclear Power Station Unit No. 1 (DB-1). The regulating rod group position limits for 0 to 60 effective full power days (EFPD) for four and three reactor coolant pump operation (Figures 8-5 and 8-10 of BAW-1707 i.e. Figures 3.1-2a and 3.1-3a of the proposed modified Technical Specifications) as submitted with the referenced letter need be revised in light of the final burnup achieved by Cycle 2 (296 EFPD). This burnup lies in the 306110 EFPD window (see Toledo Edison submittal Serial No. 755 dated November 5, 1981 submitting revision 2 to the Cycle 2 Reload Report for extension of cycle length by complete withdrawal of the axial power shaping rods and coastdown of power level towards the end of cycle). Following a reanalysis by B&W, this burnvo has resulted in relaxation of the regulating rod insertion limits for the first 60 EFPD of Cycle 3 as depicted in the attached figures.
