FLOG RESPONSE [This, response is plant specific for. Wolf Creek l Callaway and Comanche]
[ Peak.T Diablo Canyon'has provided a separate response;fTSTF-283, " Eliminate Section 3.8 Mode Restriction Notes" was not incorporated into the FLOG conversion applications since the traveler was still undergoing significant revisions at the time of submittal. The FLOG attempted to address these notes in the Bases through the application of LCO 3.0.5. These notes should not restrict the ability to credit post-maintenance testing that can be shown to provide satisfactory performance of Surveillances. As discussed in the telecon on December 10,1998,
_ the FLOG believes this traveler to be a high priority traveler and would like to see resolution of I
Attachm:nt 1 to TXX-98273 Page 4 of 9 this issue prior to issuance of the license amendment. However, the FLOG has revised the proposed ITS to incorporate the CTS requirements applicable to testing "during shutdown" to l
facilitate the schedule for issuing the amendment. Should this traveler be resolved prior to l
Issuance of the license amendment, the FLOG would work with the NRC to incorporate this i
traveler into the ITS.

CTS 4.8.1.2 states that CTSs 4.8.1.1.1.b and 4.8.1.1.2.g are applicable in Modes 5 and 6. ITS SR 3.8.2.1 states that corresponding ITS SRs 3.8.1.8 and 3.8.1.20 are not applicable in Modes 5 and 6, in conformance with the STS.
Comment: DOC 01-47-LS does not explain why the propoced changes are acceptable.
Revise the submittal to provide the appropriate justification for the proposed changes.
FLOG RESPONSE: ITS SR 3.8.1.8 is not required because thin SR tests the ability of the system to transfer from the normal operatina source tokthe attemate required,offsite 7
{seureel circuit. In MODE 5 or 6 only one power source is required, therefore, this capability is l
not required. DOC 01-47-LS 4 has been revised by the following insert:
t "and two 0"sitc sources bclng operab'e;the requirement to_ maintain.two;offsite power sources (only one offsite power; source is required in Medes MODE 5 and 6)."
ITS SR ?.8.1.20 is only required once every 10 years. The purpose of this surveillance is to demonstrate that diesel generator independence has not been compromised during the surveillance period by plant modification. This independancc is not casantla! wherc only cac ;
E@C is raqul red ic be operabla.1Therefore, the simultaneous diesel start is applicable only over L
longer periods as compared to shutdown versus operation. DOC 01-47-LS 4 has been revised by the following insert:
l
because, as stated in the Bases for SR 3.8.2.1, starting independence between DGs is not required to be demonstrated when one DG is not required to be OPERABLE."
For Wolf Creek and Callaway, ITS SR 3.8.1.8 is not applicable based on CTS.
