Reference:
(A) Telephone Conversation between J. Eckhardt and B. S. Kaplan on January 9, 1981 (B) ANPP-17236, dated February 5, 1981 (Interim Report)
Dear Sir:
The NRC was notified of a potentially reportable deficiency in Reference (A) and an Interim Report was transmitted by Reference (B).
At that time, it was estimated that a Final Report would be available by November 1, 1981.
Due to the extensive investigation and evaluation required, a revised Interim Report is attached.
It is now expected that this information will be finalized by January 30, 1982, at which time a complete report will be submitted.

INTERIM REPORT, REVISION 1 - DER 80-42 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2 AND 3 1.
Potential Problem As a result of a Bechtel Supplier Quality audit of ASME III bolt suppliers, Texas Bolt Company was suspended from the Bechtel Corporate Evaluated Suppliers List for supplying NCA3800 bolting material which is not size excluded by Code.
o Texas Bolt has failed to comply with the rules governing a Material Supplier (M/S) issuing a CMTR for material from a Material Manufacturer (M/M).
Code bolting material has been source accepted /
o shipped / installed with documentation not meeting ASME Section 111 requirements.
To evaluate the condition, Texas Bolt was visited by Bechtel to review how Texas Bolt purchases and certifies materials.
Texas Bolt buys heats of stock material and establishes heat /
lot treatability for the stock material. The stock material can be either coils of rods or bundles of bar.
The coils are always from one heat.
Texas Bolt does not weld rods together to make up a longer coil.
The bars that are steel strapped together are also from one heat.
For large orders (500 or more pieces), all bolts and studs 1\\" diameter and smaller are made from coiled rod.
All bolts and studs greater than 1\\" diameter and small orders of any size are made from straight bar.
All nuts are madelbrom straight bar.
The material test report from the stock material source states whether the product is coiled rod or straight bars, the melting practices and a chemical analysis of samples taken from the molten metal (Heat Analysis).
Each stud, bolt or nut ordered by Bechtel for ASME III applica-tions is metal stamped by Texas Bolt with a traceability code.
The traceability code is noted on the Certified Materials Test Report (CMTR) prepared by Texas Bolt, but the product form of the starting material is not noted on the CMTR. To determine if an item was made from a coil or straight bar, it is neces-sary to obtain the traceability code from the item, obtain the heat number from the Texas Bolt CMTR, and then determine the product form from the material manufacturer's material test report. The exact number of bars in a bundle is not recorded nor is there traceability between an item and a specific bar in a bundle.
Interim Report, Revision 1 i
DER 80-42 Page 2 All heat treating and mechanical testing is performed by Texas Bolt. The types and number of mechanical tests are performed as required by ASME II and III. As a minimum, the mechanical tests are done on each heat / lot of material.
Prior to February,1978, the chemical anaylsis (Heat Analy-j sis) provided by the stock material source was put on the Texas Bolt CMTR. After February 1, 1978, Texas Bolt has been using a Baird-Atomic cmission spectrograph to do an additional chemical analysis which the Code calls a product analysis.
The results of the chemical analysis performed by Texas Bolt is put on the Texas Bolt CMTR.
Between February 1, 1978 and December 11, 1980, Texas Bolt did one chemical analysis on each coil of rod and on one bar from each individually strapped bundle of bars. Since Decem-ber 11, 1980, the number of chemical analyses was increased so that every bar in a bundle is chemically analyzed.
Starting with the Winter 1975 Addenda of ASME III, NA-3767.4 (4) and subsequently NCA-3867.4(e), Materials Manufacturers (M/M) are allowed to use stock material. However, to do so, i
the M/M is required to do a chemical analysis on each piece of stock material.
For Texas Bolt, this means a chemical analysis on each coil and on each bar in a bundle. Texas Bolt has fully met ASME III, NCA 3867.4(e) since December 11, 1980 for bolting material made from straight bar and since February 1, 1978 for bolting material made from coiled rod.
II.
Approach To and Status Of Proposed Resolution The project is taking the steps necessary to obtain the required documentation to fully comply with ASME III NCA-3867. 4 (e).
For bolting material made from coiled rod prior I
to February 1,1978 and for bolting material made from straight bar prior to December 11, 1980, Texas Bolt will identify from the various quality verification document packages the traceability codes and product forms appli-cable to these categories.
Bechtel will then obtain one sample ( a bolt, nut or stud) representing each traceability code. The samples will be returned to Texas Bolt.
Texas j
Bolt will perform a chemical analysis on each sample and recertify the bolting material with a new CMTR.
l Application of Code Case N-242-1 or N-310-1 will be considered for those bolting materials made from bar stock where the required material properties are present and the traceability for each heat and lot of material can be established.

Projected Completion of Corrective Action and Submittal of the Final Report The steps necessary to resolve this condition as outlined in Section II are being implemented. The facts concerning this situation do not justify placing a project hold or j
restrictions on the continued use of Texas Bolt products.
i l
The plan to have the bolting material acceptable to ASME l
is expected to be completed and a Final Report submitted to the NRC by January 30, 1982.
