l DOC 02-17-LS-2 is comusing Comment: As worded, it appears that the CTS requirements to verify no visible l corrosion and to verify electrolyte temperature are being deleted. Apparently, I however, the intent of this DOC and associated change is to delete these requirements only following a battery discharge or overcharge. If this is correct, the DOC should be revised accordingly.

FLCG RESPONSE: DOC 02-17-LS-2 has been revised to added the following insert:

02 18 LG The definition of degradation provided in the battery service test SR would be moved to the SR Bases. The number L of connected cells that constitutes the ITS SR 3.8.6.3,

" representative cells" requirement would be moved to the Bases. This constitutes moving details that are not required to be in TS and, therefore, is acceptable. This change is consistent with NUREG 1431.
