COMMENTS ON FORT ST. VRAIN UPDATED FSAR, REVISION N0. 4 ,

We have reviewed your submittal dated July 22, 1986 (P-86466) transmitting the Fort St. Vrain-Updated FSAR, Revision No. 4. This review included Attachment 1 C to your letter, and resulted in the following comments.

1. Section 3.4.12 - Your response to NRC Comment #27 is unclear.

Please clarify your internal schedule for justifying replacement of full-length reflector blocks with half-length blocks. This should be done in the next FSAR update.

i 2. Section 7.3.1.2.1, page 7.3-9, Rev. 4 .This section, as corrected-by Rev. 4, is in error since Figure 7.3-20 does not contain a line indicating manual adjustments by steps of the PPS setpoints as indicated in Section 7.3.1.2.1 (refer to Attachment C to P-86466, NRC Comment #4).

3. Table B.5 PSC's response to NRC Comment #20, Attachment C to P-86466, indicates that Table B.5-4 is on two sheets back-to-back.

If this is a correct statement, please provide us with a copy of this table. Our FSV FSAR copy appears to be incomplete.
