SUMMARY

OF PROPOSED CHANGES Section Description of Change 4.6.1.e) This change requires a station battery and associated battery charger to be declared inoperable when disconnected from its D.C. bus to perform an equalizing charge.

This change allows a station battery and associated battery charger to be disconnected from its D.C. bus for up to 5 consecutive days to perform an equalizing charge.

This change requires the bus tie breakers between the two D.C. buses to be configured such that D.C. bus independence is maintained and the disconnect switch for the PPS battery to be open when a station battery and/or battery charger is inoperable.

Basis This change updates the discussion on the D.C. power sources and the instrument power sources to be consistent with the proposed Technical Specification change and actual plant  ;

configuration as described in FSAR Sections 8.2.2.3 and 8.2.2.4.
