I ENCLOSURE 1 RESPONSE TO NRC BULLETIN 96-02

V In accordance with the requested action of NRC Bulletin 96-02, APS has performed a review of plans and capabilities for handling heavy loads while the reactor is at power in accordance with existing regulatory guidance.

Re uired Res onse1 Required. Response 1 states:

(1) For licensees planning to implement activities involving the handling of heavy loads over spent fuel, fuel in the reactor, core, or safety-related equipment within the next 2 years from the date of this bulletin, provide the following:

o A report, within 30 days of the date of this bulletin, that addresses the licensee's review of its plans and capabilities,to handle heavy loads while the, reactor is at power (in all modes other than cold shutdown, refueling,, and defueled) in accordance with existing regulatory guidelines. The report should also indicate whether the activities are within the licensing basis. and should include, if necessary, a schedule for submission of a license amendment request. Additionally, the. report should indicate whether changes to Technical Specifications will be required.

~Res onse NUREG-0857, "Safety Evaluation Report Related to the Operation of Palo Verde Nuclear.

Generating Station, Units 1, 2, and 3," Supplement 5, Appendix D, "Control of Heavy Loads. at Nuclear Power Plants, Palo Verde Nuclear Generating'Station, Plants Number 1, 2, an 3 (Phase I)" documents the acceptance of Palo Verde's control of heavy loads.

This included a review of the establishment of safe load paths necessary to meet the requirements of Guideline 1 of NUREG-0612, Article 5.1.1(1) as well as the method for deviating from approved load paths. Supplement 7, Section 9.1.4 to the SER documents that Phase II of NUREG-0612 did not need to be implemented.

In order to ensure continued compliance with Guideline 1 of NUREG-061 2, Article 5.1 1'(1),

~

APS performed a review of plant procedures used to implement safe. load paths for heavy loads at PVNGS. The review has determined that load paths currently in use meet Guideline 1. of NUREG-0612, Article 5.1.1{1).

It is concluded. that no license amendments or Technical Specification-amendments will be required at this time.

II Re uired Res onse 2 Required Response 2 states:

(2) For licensees planning to perform activities involving the handling of heavy loads over spent fuel, fuel in the reactor core, or safety-related equipment while the reactor is at power (in all modes other than cold shutdown, refueling, and defueled) and that involve a potential load drop accident that has not previously been evaluated in the FSAR, submit a license amendment request in advance (6-9 months) of the planned movement of the loads so as to afford the staff sufficient time to perform an appropriate review.

~Res onse At the present time, APS does not plan on performing activities involving the handling of heavy loads over the spent fuel, fuel in the reactor core, or safety-related equipment while the reactor is at power and that involve a potential load drop accident that has not been previously evaluated in the PVNGS licensing basis; i.e., the PVNGS and CESSAR SERs.

Should the need arise, APS will submit a license amendment request in advance as requested in the Bulletin, as appropriate.

Re uired Res onse 3 Required Response 3 states:

(3) For licensees planning to move dry storage casks over spent fuel, fuel in the reactor core, or safety-related equipment while the reactor is at power (in all modes other than cold shutdown, refueling, and defueled) included in item 2 above, a statement of the capability of performing the actions necessary for safe shutdown in the presence of radiological source term that may result from a breach of the dry cask, damage to the fuel, and damage to safety-related equipment as a result of a load drop inside the facility.

~Res onse PVNGS does not currently have plans for the movement of dry storage casks over spent fuel, fuel in the reacotr core, or safety-related equipment while the reactor is at power.

Appropriate evalautions will be performed, and submitted as necessary, when plans are made to utilize dry storage casks.

Re uired Res onse 4 Required Response*4 states:

(4) For licensees planning to perform activities involving the handling of heavy

'loads over spent fuel, fuel in the reactor core, or safety-related equipment while the reactor is at power (in all modes other than cold shutdown, refueling, and defuefed), determine whether changes to Technical Specifications will be required in order, to allow the handling of heavy loads (e.g., the dry storage canister shield plug) over fuel assemblies, in the spent fuel pool and submit the appropriate information. in advance (6-9 months) of the. planned movement of the loads for NRC review and approval.

~Res ense No changes to Technical SpeciTications are required at this time.
