The NRC "Description of Issue" and the corresponding PVNGS responses are provided as Enclosure 1 in a tabular format similar to the RAI. ITS 3.5 submittal pages, as modified by responses to the RAI, are provided as Enclosure 2.

The response to RAI issue 3.5.5-2 is not provided in this submittal, and will be provided in a future submittal. This deferral of RAI issue 3.5.5-2 to a future submittal is necessary in order to properly address the issue yet still provide the other RAI responses to the NRC on an accelerated schedule, as requested by Mr. Charles Thomas of the NRC staff.

Generic change TSTF numbers 058, 059, and 078 to NUREG-1432, Revision 1 are incorporated into ITS Section 3.5.
