I U.S. Nucl:ar Regul: tory Commission 2- November 18,1997 The proposed Technient Specification amendment request stated that, pending approval of the use of the 1996 Addenda of the ASMF Code and the integration of weld metal surveillance programs, new pressure tempc.,. are (P/T) curves would be submitted to the Stalt i'er conversations with the Staff, Comed has been requested to submit the attached supplement to the proposed Technical Speelfication before the final approval of the 1996 Addenda of the ASME Code and the integration of weld metal surveillance programs.

We understand that approval of the 1996 Addenda of the ASME is imminent. Comed will be submitting a revision to the description of weld metal surveillance program integration (WCAP 14824)" Byron Unit 1 IIcatup and Cooldown Limit Curves for Normal Operation and Surveillance Weld Metal Integration for Byron and Braidwood "

to the Staffin November.

l The following attachments reflect incorporation of the 1996 Addendum and the revised WCAp-14824:

- WCAP-14940 "flyron Unit 2 Ileatup and Cooldown Limit Curves for Normal Operation" and Erratta Sheet (Westinghouse letter CAE 97 210, CCE 97 289);

- WCAP 14970 "llraidwood Unit 2 Heatup and Cooldown Limit Curves for Normal Operation" and Erratta Sheet (Westinghouse letter CAE 97-210, CCE 289);

- Revision to " Byron Unit 1 Pressure and Temperature Limits Report" and "Braidwood Unit 1 Pressure and Temperature 1.imits Report" which includes the following:

- Note added that 1996 Addenda was not used for Byron and Braidwood Unit 1 Pfr curves;

- Tenable temperature revised ts 200 F based on WCAP-14824 Revision 2  ;

data

- Revised Table 2.1 and Figure 2.3 for clarity;

- Revised Table 4.1-4.6, to incorporate WCAP-14824, Revision 2;

- References modified to incorporate WCAP-14824, Revision 2 throughout the document; Editorial changes to address typos, page numbers and minor comments; and

- Revision to "Hyron Unit 2 Pressure and Temperature Limits Report" and "Braidwood Unit 2 Pressure and Temperature Limits Report" which includes the following:

- Incorporated revised WCAP 14940 (WCAP-14970 data for Braidwood) ,

into Tables 4.1 through 4.6;  !
