DOCKET NOS. 50-445 AND 50-446 ADVANCE FSAR SUBMITTAL-SECONDARY CYCLE WATER CHEMISTRY LIMITS Gentlemen:

This'1etter provides an advance copy of a change to be included in a future

.FSAR amendment. This change revises a table to reflect typical pH limits of~

the secondary cycle water. chemistry.

In order to facilitate NRC Staff review of this change, the attachment is organized as follows:

1.

Draft revised FSAR pages, with change portions indicated by a bar in the margin, as they are to appear in a future amendment.

2.

A detailed description / justification for the change...

3.

A copy of a related SER section.

4 A page containing the title of a " bullet" which consolidates and categorizes similar individual changes by subject and related SER section.
