Dear Mr. Randolph:

~

l The Nuclear Regulatory Commission staff is reviewing Union Electric Company's proposed.

license amendment to convert the current technical specifications for Callaway Plant, Unit 1 to the improved Standard T.echnical Specifications. Union Electric Company provided their proposed license amendment request by letter dated May 15,1997.

The staff has reviewed selected portions of the application. Based on its review, the staff has determined that additional information is needed in Section 2.0, Safety Limits and Secuon 3.0, Limiting Condition for Operation Applicability / Surveillance Requirement Applicability. as discussed in the enclosure. Since you worked with three other utilities in preparing your submittal, the enclosure contains the request for additional information (RAI) questions for all

~ four utilities. However, you need only reply to the RAI questions associated with Callaway Plant, Unit 1 as identified in the table within the enclosure.

To assist the staff in maintaining its review schedule, please respond to the questions pertaining to Callaway Plant, Unit 1 within 30 days of the date of this letter, if you have any questions regarding the RAI, please contact me at_(301) 415-1362. If all four utilities would like to have a common discussion, a single meeting, or phone call, it can be coordinated by contacting the NRR Lead Project Manager, Timothy J. Polich at (301) 415-1038.

Sincerely,.

FOUR LOOP GROUP (FLOG) IMPROVED TS REVIEW COMMENT 8 SECTION 3.0 - LIMITING CONDITIONS FOR OPERATION APPLICABILITY /

SURVEILLANCE REQUIREMENT APPLICABILITY l

3.0 1 ITS SR 3.0.3 CTS SR 4.0.3 (All FLOG Plants)

DOC 1-20-A Comment: The CTS Markups of CTS SR 4.0.3 for all FLOG plants do not accurately reflect the ITS end product, SR 3.0.3 (ITS 3.0.3 is compatible with the STS and acceptable). Correct CTS Markup, or revise ITS Markup and provide justification.

FLOG Response:

3.0 2 ITS SR 3.4.13.2 / Administrative Controls Section 5.5.9 I

CTS 4.0.6.4a (Comanche Peak)

DOC 1-15-A i

Comment: The ITS revises the wording of CTS 4.0.6.4a.8. Is this also applicable to the other FLOG plants in which the location of this paragraph is CTS SR 3/4.4.5; is it generic?

FLOG Response:

3.0-3 ITS LCO 3.0.5 Bases (All FLOG Plants)

Comment: The STS Bases has been revised to address "the performance of required testing" versus the " performance of SRs," to be consistent with the TS. Submit a TSTF to revise the STS. Suggest that the first instance this wording is to be revised to state,"the performance of required testing including applicable SRs," since testing to restore equipment to an operable state will frequently include the performance of SRs.

FLOG Response:

3.0-4 ITS SR 3.0.2 Bases (All FLOG Plants)

Comment: Justify the revised STS SR 3.0.2 Bases. The STS provides an explanation for the inapplicability; the ITS does not.

FLOG Response:

K 3.0 5 ITS LCO 3.0.1 & 3.0.2 CTS 3.0.1 & 3.0.2 (All FLOG Plants) l DOC 1-01-A Comment: The markup of CTS 3.0.1 and 3.0.2 do not agree with the markup of STS LCO 3.0.1 and LCO 3.0.2. The markup of STS LCO 3.0.1 and 3.0.2 are correct. Revise the CTS markup.

FLOG Response:

3.0-6 ITS LCO 3.0.4 CTS 3.0.4 (All FLOG Plants)

DOC 1-02-LS1 Comment: The markup of CTS 3.0.4 does not agree with the markup of STS LCO 3.0.4. The markup of STS LCO 3.0.4 is correct. Revise the CTS markup.

FLOG Response:

3.0 7 ITS LCO 3.0.4 Bases (Diablo Canyon)

Comment: The redline / strikeout markup of the STS LCO 3.0.4 Bases is incorrect. Correct the markup of the STS LCO 3.0.4 Bases.
