Gene Stanley and Ken Graesser (Commonwealth Edison) letter to NRC Document Control Desk,
" Conversion to the Improved P
'ard Technical Specifications," dated Decembc.3,1996 As requested in the December 15,1997 meeting between representatives of Commonwealth Edison (Comed) and the NRC staff, Corned has identified the deviations between TSTF-135 Revision 0 and the Comed submittal (Reference 1) for Section 3.3 LCOs 3.3.1 and 3.3.2. The following paragraphs discuss the differences we have noted.
The generic changes (TSTFs) included in the Comed submittal for the LCOs and bases for Section 3.3 are TSTF 135 Revision 0, identified as Justification for Difference (JFD) C3 and TSTF-169 (WOG-80), identified as JFD C. the NRC staff 5
approved TSTF 169 during the October 1997 TSTF meeting.
Another deviation from TSTF-135 Revision 0 is a beyond scope change included in Section 3.3 and identified in Attachment 5 for tiie Split Report. The change was identified as. item #3 in the attachmeiit, addressing Auxiliary Feed Water pump inoperability of LCO 3.3.2 and justified at a plant specific change to the NUREG LCOs, P e, and a less re,stpctive change to CTS, L7 i

U.S. NRC Januaru 29,1998 There are 35 other plant specific changes made to TSTF-135 Revision 0, and identified in the Jusufication for Differences to the NUREG-1431 LCOs section of the ITS submittal. Thirteen of the identified changes delete conditions and footnotes not required per the current Byron /Braidwood Technical Specifications, or are reflected in another applicable condition of the LCO. These changes are identified in Attachment A.
Also identified, are 16 plant specific changes to TSTF-135 Revision 0 that reflect current plant requirements, wording, and design. These changes are identified in Attachment B.
There have been two plant specific changes to TSTF-135 to match the intent indicated in the bases:
Pi2 TSTF-135 LCO 3.3.2, Required Action P.1 is revised to match the Bases which indicate the unit must be put in a Mode for which the Function is not required.
P4s ITS LCO 3.3.1 Required Actions D.1, J.1, and L.1, and LCO 3.3.2 Required Actions B.1, D.1, F.1, G.1, H.1, K.1,0.1, and 0.1 are revised to match the intent as described in the associated Bases. Each of 3
these Required Actions are revised from " Restore channel (s)..." to
/
" Restore all but one channel..."
Three other plant specific changes to TSTF-135 revise the NUREG specified wording to reflect proper function:
P7 TSTF-135 Table 3.3.1-1, Function 11, Footnote (g), and associated Bases have been revised to reflect one function rather than two separate functions Psi TSTF-135 Table 3.3.1-1, Function 15, Footnote (f), and associated Bases have been revised to reflect the Mode of Applicability for the Turbine Trip Function.
Ps TSTF-135 Table 3.3.2-1, Function G.a and Function 6.b and t
associated Bases have been revised to combine the two Functions.
This identifies all deviations from the generic traveler, TSTF-135 Revision 0. We hope this will assist you in your review of the Byron and Braidwood ITS submittal for 'he Instrum 2ntation Section 3.3.
