SUBJECT: NOTICE OF VIOLATION

NRC INSPECTION REPORT NOS. 50-528/529/530/93-12

This refers to the inspection conducted by J. Sloan, 4. Freeman,

A. MacDougall, F. Ringwald, and B. Olson of this office, on April 27 through

L May 31, 1993. The inspection included a review of activities authorized for

your Palo Verde facility. At the conclusion of the inspection, the findings

l were discussed with those members of your staff identified in the enclo, sed

report. -

Areas examined during the inspection are identified in the report. Within

these areas, the inspection consisted of selective examinations of procedures

and representative records, interviews with personnel, and observation of

activities in progress.

l Based on the results of this inspection, certain of your activities appeared

'

to be in violation of NRC requirements, as specified in the enclosed Notice of

Violation (Notice). This violation involved the failure to test snubbers as

required by Technical Specifications and is of concern because you had-

addressed this issue previously, but did not identify the violations and

implement corrective actions. In addition, one non-cited violation was

identified regarding an operator not following a procedure in response to the

April 21,1993, turbine trip in Unit 3.

The inspectors also identified two examples of weaknesses in operability

determinations. In ene case, APS personnel determincd that a feedwater

isolation valve was operable without adequate assurance that it could perform

its safety functior.. In another case, we noted that the troubleshooting

performed to cor. firm the initial operability determination of a containment

hydrogen control valve was delayed even though the root cause of the

deficiency was not clearly identified. Although these examples did not

represent violations of NRC requirements, we are concerned that further

management attention is needed to ensure that operability determinations are

performed in a timely manner and consistent with guidance of Generic Letter 91-18.

The inspectors also identified that the assembly and accountability drill

conducted on May 26, 1993, to correct problems encountered during the. steam

generator tube rupture event, allowed a one-hour assembly period prior to 4

beginning the 30-minute clock for accountability. In our view, this drill did

not demonstrate your capability to assemble and account for personnel within

the required 30 minutes. We strongly encourage you to assure yourselves that

you can meet assembly and accountability requirements during any future event.

You are required to respond to this letter and should follow the instructions

specified in the enclosed Notice when preparing your response. In your- l

response, you should document the specific actions taken and any additional

-

actions you plan to prevent recurrence. After reviewing your response to this

Notice, including your proposed corrective actions and the results of future

inspections, the NRC will determine whether further NRC enforcement action is

necessary to ensure compliance with NRC regulatory requirements.

In accordance with 10 CFR Part 2.790 of the NRC's " Rules of Practice," a copy

of this letter and the enclosures will be placed in the NRC Public Document

1

Room.

The responses directed by this letter and the enclosed Notice are not subject j

to the clearance procedures of the Office of Management and Budget as required 4

by the Paperwork Reduction Act of 1980, Pub. L. No. 96.511.

Should you have any questions concerning this inspection, we will be glad to

discuss them with you.
