Dear Sirs:

Subj ect:

Palo Verde Nuclear Generating Station (PVNGS)

Unit 1 Proposed Technical Specification Change to Section 5.3.1 Design Features of the Reactor Core Fuel Assemblies File: 91-056-026; 91-005-419.5 In accordance with 10 CFR 50.90, Arizona Public Service Company (APS) submits herewith a request to amend Facility Operating License NPF-41, for PVNGS Unit 1.

The proposed amendment adds a

sentence to Technical Specifications, Design

Features, Reactor Core Fuel Assemblies, Section 5.3.1, to allow the substitution of up to a total of 80 fuel rods clad with advanced zirconium-based alloys other than Zircaloy-4 in two fuel assemblies for in-reactor performance evaluation purposes.

Description of Proposed Technical Specification Amendment Request Purpose of the Technical Specification Need for the Technical Specification Amendment No Significant Hazards Consideration Determination Safety Analysis for the Proposed Change Environmental Impact Consideration Determination Marked-Up Technical Specification Change Pages Enclosure B

includes five copies of a proprietary report entitled

~SaEee Evaluation Re ort for Use of Advanced Zirconium Based Claddin Materials in PVNGS Unit 1 Batch F Demonstration Fuel Assemblies, containing specific descriptions-of the elemental composition of eight advanced alloys and testing results.

In accordance with 10 CFR 2.790, ABB Combustion Engineering, the owner of this

report, requests that this proprietary report be withheld in whole from public disclosure on the grounds that the specific alloy information in the report is considered to be confidential commercial information.

The affidavit required by 10 CFR 2.790 (b)(1) to sQpport this request for confidentiality is also included in Enclosure B.

Non-proprietary information from this proprietary report was used to prepare the Safety Analysis in Enclosure A.

Spec.

Change to Section 5.3.1 Page 2

The Safety analysis in Enclosure A provides a basis for the conclusion that 10 CFR 50.46 criteria will be satisfied for the advanced alloys because the behavior of these alloys is expected to be essentially the same as that of conventional Zircaloy-4.

However, an application for an exemption to 10 CFR 50.46 is included in Enclosure C, along with an exemption request for 10 CFR 50, Appendix K, and 10 CFR 50.44.

APS intends to install the two fuel assemblies containing advanced alloy clad fuel rods during the next Unit 1 refueling outage, scheduled to begin in February 1992.

The vendor does not intend to fabricate these fuel assemblies prior to NRC approval of this request.

Therefore, APS is requesting NRC approval by January 2, 1992.

APS is available to meet with the NRC Staff, if necessary, to support the review and approval of this amendment.

Pursuant to 10 CFR 50.91(b)(1),

a copy of the proposed amendment is being forwarded to the Arizona Radiation Regulatory Agency.

If you should have any questions, please contact Michael E. Powell of my staff at (602) 340-4981.
