Response 13 The only technical specification and design change necessary to effect long term resolution of the items expressed in IE Bulletin 79-06A is a modification to the pressurizer safety injection logic. This modification would delete the level coincidence and alter the pressure coincidence to a 2 out of 3 low pressure logic.

The design change and technical specification change requests are presently being routed through normal company channels for implementation and submittal to the Commission.
