FINAL REPORT:- DER.84-211 I b2FICIENCY. EVALUATION 50.55(e).

ARIZONA'PUBLIC SERVICE COMPANY (APS) x PVNGS UNITS 1, 2, 3 4I.- DescripEion'of'Deficidacy-During a routine site. audit, the following_ discrepancies between i design drawings and "as-built", configurations.were noted:

A. ' Combustion Engineering (C-E). Drawings N001-13.01-727 andL-728'

- specify 300 series stainless. stee1' instrument-to-bracket mounting '

hardware for Rosemount transmitters supplied by 'C-E.' NCR SJ-37121 documents the use in Unit 1 of numerous carbon ' steel nuts and .

bolts having no grade markings and strong magnetic properties. ,

B. - Bechtel Drawings 13-J-ZZS-161, -162, -165, -166,~ -167, -168,

-174, and .-178 specify ASTM A193,' CL2 and GRB8 bracket-to-panel

~

mounting nuts and bolts for certain Rosemount transmitters. NCR- 2 SJ-3713 documents nuts without proper marking cut many transmitter installations in Unit 1.

Following the initial routine site audit, an extensive walkdown was done in Units 1 and 2. "

'EvaluaEion The subject transmitters measure pressure, level, and flow-rates in several safety-related systems. (LPSI pump A discharge flow, reactor coolant system pressure,' steam generator level.and MSIV hydraulic-accumulator pressure). Specific tag numbers for transmitters are identified in referenced SFRs and NCRs.

These instruments require mounting hardware of specific grade

material, along with proper docunentation and identification mark to

+

permit traceability. Also, thecinstallation of these transmitters should strictly adhere to mounting procedures and. detail inspection and acceptance codes.

In the event of a DBE, instruments not properly mounted could become. ,

disengaged and not perform their intended safety function.

The. root cause for the deficiencies described herein is the craftsmen's failure to pro'perly install the ins'truments and the failure of field-engineers and quality control to identify the use of improper materials.

II. Analysis of Safety Implications l; Based upon the>abovei this condition is evaluated as reportable under L 10CFP50.55(e); since, if left uncorrected, it could represent a L 'significant safety hazard.

= .

l This condition is evaluated as not reportable under 10CFR Part 21

l. since it does not constitute a' defect in a basic component.

III. Corrective iction-In Units 1 and 2 mounting hardware (bolts and nuts) were replaced to

conform with material,and installation requirements. In certain cases, the vendor (C-E) advised that specific installed hardware were an acceptable substitute (e.g., carbon steel in lieu of 300 series ,

stainless steel). Where this occurred, the vendor prints were revised (see referenced FCR) to reflect the alternate acceptable '

material. The above corrective action will be implemented and documented -by referenced.SFRs/NCRs list in Section IV.

Specific instructions'(IOM-E-11465) have been issued to Construction

to assure proper installation and preclude recurrence of this deficiency in Unit 3. - Also, a walkdown of 26 sample Q-class installations per unit is being done per Project Validation of Q .

Instrument Procedure No. 5.26-08 to'further assure that other Q-class installations are installed per the requirements of the design documents.
