Subject:

Revision to Technical Specification Amendment-Sections 1.0, 2.2, 3/4.1, 3/4.3, 3/4.10.

Dear Sir:

At the time the Reference (1)letter was submitted, it was assumed that the Temperature Dependent Shutdown Margin Technical Specification Amendment, Revision 0, (Reference 2)would be approved and therefore the Shutdown Margin graph, of Fig.3.1-1A would be used for Cycle 1 operation.

Based on that assumption, the Cycle 2 Shutdown Margin amendment, Attachment 2 of the Reference (1)letter, was developed accordingly.

However, during the Cycle 2 reload review, an error in the Inadvertent Boron Dilution Event analysis was identified.

As a result of'he reanalysis, the Technical Specification Amendment of the Reference'2).letter, concerning the Temperature Dependent-Shutdown Margin graph, required changing.Because of the change made to the Cycle 1 Shutdown Margin Technical Specification amendment graph the same change is required for the Cycle 2 graph.The justification for the change is given in the Reference (3)letter.The change to the Cycle 2 amendment is Specification changes and not the Cycle 2 justifications as discussed in the Reference graph requires replacement.

Attached is the the result of the Cycle 1 Technical reanalysis, therefore, the reasons and (1)letter remain the same and only the revised page.By copy of this letter, we are agency.also forwarding the revision to the appropriate state 8708260ih5 870820 PDR~ADQCK 05000528 p PDR oo4>)L I t I USNRC Document Control Desk Revision to Reload Technical Specification Amendment-Attachment 2, Shutdown Margin 161-00454 Page 2 August 20, 1987 Xf you have any questions, please call W.F.Quinn, at (602)371-4087.Very truly yours, 4 P~p.G.Haynes Vice President Nuclear Production JGH/LJM/ls Attachment cc: 0.M.E.E.A.C.J.R.J.B.G.N.E.A.C.E.De Michele (all w/a)Van Brunt, Jr.Gehr Ball Martin Knighton Licitra Tedford
