DEFICIENCY EVALUATION 50.55(e)= .l ARIZONA PUBLIC SERVICE COMPANY (APS)-

PVNGS UNITS 1, 2,'3- i 1

I. Description ~of Deficiency During a routine site audit,'the following discrepancies'between design drawings and "as-built" configurations were noted:

j; A. Combustion Engineering '(C-E) Drawings N001-13.01-727 and -728

. specify 300 series stainless steel instrument-to-bracket mounting hardware for Rosemount/Barton transmitters supplied by C-E.E NCR l SJ-3712 documents the use in Unit 1 of numerous carbon steel nuts and bolts having no' grade markings andl 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/Barton l o transmitters. fNCR SJ-3713 documents nuts without proper marking.

. on many transmitter installations in Unit 1.

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

, Evaluation l 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 i- material, along with proper documentation and identification mark t'o i permit traceability. Also, the installation 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 craf tsmen's failure to properly install the instruments and the l failure of field engineers and quality control to identify the use of

- improper materials.

l

! II. ' Analysis of Safety Implications Based upon the above, this condition is evaluated as reportable under.

j.

-10CFR50.55(e); since, if left uncorrected, it could represent a significant safety hazard.

L-This condition is evaluated as not reportable under.10CFR Part 21 -

, - since it.does not constitute a defect in a basic component.

3 ' III. Corrective Action In Units 1 and 2 mounting hardware (bolts and nuts) were replaced to

~

' conform with material and installation requiremetits. 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/NCRa 1ist in Section IV.' - A definitive

~

list of the affected Rosemount/Barton transmitters is given 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 Valide.cion 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.

Recognizing the need to address the generic implications of improper

Q-Class instrumentation installations, the ANPP has initiated a l comprehensive review of Q-Class instrumentation deficiencies. This

review will evaluate Q-Class instrumentation installations to provide

assurance that Q-Class instruments are installed per the requirements

of applicable design documents. The scope of the evaluation and the results, including the sample walkdown conducted above, will be included in the final report for DER 84-27.
