Subject:

Palo Verde Nucleax'enexating Station (PVNGS)

Units 1, 2 and 3 Docket Nos. STN-50-528/529/530 Pile: 83-056-026 G.1.01.10 Refex'ence: CESSAR Safety Evaluation Report Supplement No. 2 (NUREG-0852), dated September, 1983.

Dear Mr. Knighton:

The referenced document, Section 4.4.6.2(b) discusses CPC/COLSS overall uncertainty factors. In particular, page 4-24 states, "for each plant referencing CESSAR, the as-built error components should be compared to these generic values to verify that the generic values are bounding".

Combustion Engineexing has reviewed oux's-built components and determined that the PVNGS error components are bounded by the generic CESSAR values.

We believe this information adequately responds to the CESSAR SER section 4.4.6.2(b) (page 4-24) statement.

If you have any questions, please contact me.

Very truly yours, E. E. Van Brunt, Jr.
