Licensee Action on previous Inspection Findings (Closed) Unresolved Item (498/499-8316-03) Failure to Identify Required Standards: Possible Nonconforming Installation._ During a review of the requirements placed on subcontractors providing material and services for South Texas Project (STP), the NRC inspector noted that the American Institute for Steel Construction (AISC) specification for the bolting of high strength materials had not been directly invoked.
In particular he was concerned with the AISC prohibition on the reuse or retorquing of galvanized A-325 bolts. This was considered to be an unresolved item pending further review.
!
A further review revealed that the contractor in question, Bostrum-Bergen, was awarded the contract to supply various steel parts and assemblies on July 30,1976. At this time the document in effect was the 7th Edition of the AISC specification for bolting. The prohibition on the reuse or re-torquing of galvanized A-325 botting material first appeared in the AISC 8th Edition, issued in 1980. This ban was introduced to avoid the question-
,
'
able tightening that could result when bolts with relatively rough thread surfaces are subjected to successive cycles of forceful torquing. Although the prohibition on retorquing was not specifically invoked, it.was included in the ordering data by reference.
The galvanized bolts as well as all other bolts furnished by this suppiter were tot shop assembled and tightened as permanent bolted connections.
Therefore, the galvanized bolts were not subject to tightening on the part of the supplier. The subsequent onsite torquing and use of these bolts does j
not appear to violate the AISC specification or present a potential deficiency I
within the suppliers scope of operations.

(Closed) Violation (498/499-8202-01) Failure to Report Desion or_
While conducting fonstruction Deficiencies Within the Required Time.
in investigation at STP, the NRC inspector noted an apparent violation of the timely reporting requirements of 10 CFR 50.55(e).
This regula-tion recuires that the holder of a construction permit notify the appropriate NRC Regional Office, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery, of any i

deficiency found in design or construction, which, if uncorrected, could adversely affect the safety of plant operations.
,
Contrary to this, two deficiencies were found by the applicant on or
'
about November 1980 and January 1981, respectively, but were not reported tc the NRC Region IV Office within the required 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
The original notification for each was received on May 8,1981, after a delay of approximately 4 months. This ' violation and the two specific examples are detailed in Investigation Report 498/499-8202.
The licensee agreed that there was a failure to report one of the items but determined that the second was not reportable pursuant to
!
10 CFR 50.55(e). This actual significance of the second item did
,
not becore apparent until the detailed findings of the Quadrex Report became available on May 7,1981. HL&P formally notified the NRC Region IV Office or. May 8,1981, the day following their receipt of the informa-tion necessary to fully evaluate the reportability.
,
As a result of this violation the deficiency riporting procedures have been revised and employees have been retrained in order to reduce the potential for a failum to comply with these reporting requirements.
Procedure PEP-4.01 was rewritten and reissued as PLP-02, " Reporting Design ar.t Construction Deficiencies to the NRC," dated May 18, 1982.
PLP-02 no. clearly state the requirements for reporting and change the lead risponsibility for initial notification of all deficiencies
>
solely te the Team Leader, Nuclear Licensing.
It also rumoved the distincticn between site and home office handling of deficiencies and clarified the role of engineering in the evaluation process.
The NRC ir.spector has reviewed procedure PLP-02 and subsequent revisions to deterr'ne its adequacy and clarity. The NRC inspector made a random selectior. of eight deficiency notifications received subsequent to this violatior, and verified that each had been promptly reported. Three of these wars originally reported as "potentially reportable" items and were lata, determined to be reportable. Following these reviews the NRC inspe-tor had no further questions.

(Closed) '_%esolved Item (498/499-8209 04). Structural plates and Bars and :lat Washers for Reactor Coo _lant System (RCS) Supports.
The NRC tr.spector noted an apparent conflict between the requirements of the ST.: FSAR and the Brown and Root (B&R) specifications for l
materials used in the RCS supports. The conflict in requirements was
,
identified when FSAR Section 3.8. 3.6.5.1 was compared to B&R Specification 1C11955015E/DCN dated June 2,1977. The STP FSAR specified that materials for RCS supports, structural plates, shapes and bars art to be ASTM A588 corrosion resistant, high strength, low alloy steel. The FSAR, in the same section, also specified that flat washers were to be quenched and tem-pered caroon steel. B&R Specification IC11955035E/DCN dated June 2,1977,
-
however, specifies the use of ASTM A36 material for thicknesses greater

-7-than 8 inches in this appitcation. A second discrepancy was noted wherein l
the B&R_ specification allows the use of ASTM A36 material for use as flat washers.
The response to this item stated that it is not a requirement that the F5AR reflect all materials and processes used on the project. It is the intent of the project that the FSAR identify only the basic materials and l
,
'
processes used. The response stated that an SAR change notice had been initiated to clarify this position and to identify the basic materials and processes which are being used.
The NRC inspector reviewed Section 3.8 of the STP FSAR and found that Revision 40 incorporated several approved changes. The material to be used for RCS supports is now clearly stated as ASTM A588. Section 3.8.3,6.4.1 has also been changed to allow the use of either quenched and tempered carthon steel or ASTM A36 material for flat washers used in the RCS supports.
The NRC inspector had no further questions following his review of SAR Revision 40.

(Closed) Un esolved Item'(498/499-8322-04) 88R Calibration and Control of Gaces and Other Inspection and Test Tools Reautring Calibration.
During a review of records in the calibration laboratory, the NRC inspector reviewed a number of recalibration records where the calibration status of the equipment, as received for recalibration, was not recorded, precluding determination that the equipment was within calibration when returned. The identification numbers of l
seven gages and/or tools were listed as examples. This item was considered as unresolved pending further review of calibration l
procedures and implementation.
The NRC inspector reviewed the calibration records of the specific tools and gages listed in the inspection. This review revealed that six of the seven itens were "Go-No-Go" thread ring gages and
l the seventh was a crimping tool.
Instrument Engineering Instruction IEI-42 did not require an entry in the " Data as Received" l
and " Data After" sections of the calibration record since these data l
l sections are not applicable to ring gages. The seventh item, a l
crimping tool, was placed in a " hold" status on May 14, 1980, and has never been issued for use. In these instances the calibration lab
'
was correct in not entering data in the "as received" sections.

Records Office was still being progressed through the review cycle j
prior to issuance. An Ebasco staff member stated that interior
'
guidance would be provided to personnel handling records until the procedure is fully implemented (end of September 1982). Because of the small number of documents being processed at the time of this inspection, the response was acceptable to the NRC inspector, pending
_
'
his further review following the procedure issuance.
The NRC inspector has reviewed QAI-016. " Control of Site Quality Records",
as issued for use on September 13, 1982. Based upon the issuance and implementation of this procedure within the specified time, the NRC inspector had no further questions.

IE Bulletin Followup
-
The NRC inspector rtviewed the available documentation pertaining to the IE Bulletin (IEB) listed below, to assure that the Itcensee management had
,
l
'
received the bulletin, that a review for applicability was performed, and, if applicable, that the required actions had been taken; i.e., conducting an evaluation to demonstrate that the materials were suitable for intended service, or replacing discrepant materials with materials which have been
manufactured in full compliance with Section III of the ASME Code and the
'
applicable procurement specification requirements.
IEB 83-06 Nonconforming Material Supplied by Tube-Line Corporation Facilities at Long Island City, New York; Houston, Texas; and Carol Stream, I
IEB 83-06, dated July 22, 1983, was received by HL&P, and an investigation was conducted by them and their architect-engineer, Bechtel.
With respect to IEB 83-06, HL&P provided a final response to the NRC in a letter dated April 30, 1984. This response stated, in part "... we have not identified any Tube-line material that has been supplied to the STp for use in safety-related systems... we reviewed the STP purchasing for safety-related pipe fittings and flanges of the type supplied by Tube-Line and identified 35 vendors that could have supplied Tube-Line material to the project... Each of the 35 vendors was then provided with the project's purchase order listings and asked to identify any Tube-Line ASME Code Section III material furnished to the project. All 35 vendors have responded, stating that no Tube-Line ASME Code Section III material for use in safety-related systems had been supplied to the STP."
The NRC inspector reviewed copies of the available Bechtel letters and the responser, received from 19 vendors. All of the vendors, except one, indicated that they had not provided Tube-Line material to STP.
The resp 6'nse from Guyon Alloys, Inc., stated that several items from Tube-

-g-Line had been furnished to STP; however, the Bechtel purchase orders (PO)
'
had not required processing in accordance with their quality program and only certificates of compliance were required.
It was established that the subject PO's were not for safety-related material.
The NRC inspector reviewed 14 documentation packages consisting of PO's, vendor documentation, and receiving inspection reports pertaining to
'
i l
materials provided by Gulfalloy, Inc., 1 of the 19 vendors.
The Gulfalloy, Inc., response letter to Bechtel was dated April 13, 1983, and stated, in parts ",,, Gulfalley has not supplied any matarials either manufactured or supplied by Tube-Line for the South Texas Project...."
i One of the 14 documentation packages contained a Brown & Root Inc.
(the original architect-engineer for STP) P0 to Gulfalloy, Inc.,
No. 35-1197-19432, dated July 18, 1979, for 200 each, 1-1/2", Schedule 40, A-234 WPB, Long Radius, Socket Weld, 900 Elbows.
l The P0 states, in part, "This is a ' Nuclear Safety-Related' Order
... Vendor shall furnish... Certified Material Test Reports (CMTRs) For Each Heat / Lot of Materials Delivered... And Evidence Conformance to the i
i Requirements of ASTM A-234...." Additional documents in the package consisted of a CMTR from Tube-Line. Inc., Long Island City, New York, and a
'
i B&Rreceivinginspectionreport(RIR). The CMTR is dated Ju-ly 20,1979, and shows 200 each,1-1/2", 90o long radius elbows, of A-234 WPB material.
B&R's RIR No. 3558 shows that 200 elbows were received on August 6, 1979, accepted and released. Thus, there is an apparent conf 1fet between the data
>
contained in the documentation package, the Gulfalloy response to Bechtel, and the HL&P bulletin response to the NRC.
In addition, with respect to the Tube-Line CMTR, the ASTM Material Specifica-
i tion A-234 requires that when CMTRs are requested by the purchaser, the manufacturer shall report the results of the chemical analysis, tension test results, and the applicable heat treatment applied to the material and to the test pieces. The Tube-Line CMTR did not address heat treatment.
It should also be noted that this documentation package was reviewed for i
adequacy by Bechtel on August 16, 1984, and accepted as evidenced by a Bechtel stamp with number.
Another concern pertaining to the HL&P/Bechtel evaluation deals with Bechtel's
!
I data accumulation and usage.
Prior to the issuance of IEB 83-06 on July 22, 1983. Bechtel received infonnation about potential 10 CFR Part 21 reports
'
filed with the NRC by Capitol Pipe & Steel Products Company and Babcock &
Wilcox Company on December 6,1982, and January 10, 1983, respectively,
,
dealing with Tube-Line, Long Island City, New York. Subsequently, but still prior to the issuance of the bulletin, Bechtel sent letters to certain vendors (Gulfalloy Corporation, Capitol Pipe & Steel Products Company, McJunkin Corporation, ar.d Guyon Alloys, Inc.) requesting confinnation that no Tube-Line material had been supplied to STp.
The letters also orovided the PO numbers and referenced only 2-i_nch

Allegation Followun
_ _ -An allegation was received via telephone by the NRC Region IV Office concern-
{
The alleger ing the QA program of a major supplier of steel to the STP site.
stated that Sheffield Steel Corporation was supplying large quantities of structural steel to the STP construction site although the company had no quality program to assure that the material shipped confomed j
l'
to the P0 specifications.
In NRC report 83-21 it was stated that PO 35-1197-6001 was issued to J
Amco Steel in 1975 to supply all of the concrete reinforcing steel Prior to issuing this P0 i
to be used for the construction of STP.
a review was made of the Armco Steel Quality Assurance Manual by HL&P l
HL&P coments were incorporated into the manual and the personnel.
program was accepted as being in compliance with all applicable requirements.
i When Amco Steel was sold and the name changed to Sheffield Steel, the only I
change made to the QA Manual was in the name.
!
The Sheffield Steel QA Manual was reviewed by the NRC inspector and was
,
found to be complete and comprehensive. Personnel responsibilities, l
document control, program requirements, personnel qualifications, training, audits, nonconfomances, corrective action and vendor i
requirements are delineated in detail. The NRC inspector also reviewed several of the Sheffield Steel procedures utilized in the testing, storage, and shipping of reinforcing steel and all were found to be in compliance with the QA manual.' The NRC l'nspector reviewed a sample of the test records received for various lots of reinforcing steel. Each contained quantitative results for yield, tensile, elongation, and chemical analysis of each heat
of material.
The NRC inspector's review of the QA manual, material test records, and quality engineering evaluation of documentation revealed no conditions onsite to ' ndicate that the Sheffield Steel QA program, as stated, was not Because of the nature of the allegation, it was being fully implemented.
forwarded to the NRC Region IV Vendor Inspection Branch for further evalua-tion.

the three items be acted upon and that records and results of these actions
!
be provided for NRC review.
As a result of this request records were presented to the NRC inspector to document the following:
a.
On May 11, 1984, HL&P issued a letter to Bechtel requesting that
'
specific actions be takcn and answers provided concerning the quality program at Sheffield Steel.
b.
A joint audit of Sheffield Steel was performed by Bechtel and HL&P during the period May 23-29, 1984, which resulted in ten findings.
Three stop shipment orders were issued because of these findings.
On June 1,1984, a Nonconformance Report (NCR) BC-00452 was issued.
c.
This NCR placed a " Hold" on all questionable reinforcing steel until it could be reinspected.
d.
On June 12, 1984, Sheffield Steel reassigned all of their inspectors to the Quality Control (QC) organization rather than production. This was done as a result of the NRC inspection and the finding of the joint audit. On this day Bechtel also removed the stop shipment order based
,
upon the results of the reinspection performed.
e.
On June 18,1984, Bechtel issued a letter to Sheffield Steel listing 13 heat numbers of material which were to be quarantined and pemanently barred from shipment to STP.
f.
On June 30,1984, a reaudit of Sheffield Steel was conducted by Bechtel.
The results of this reaudit indicated that all previous findings had been adequately addressed and the proper corrective actions taken. Although no additional adverse findings were identified, all of the documentation for each future Sheffield Steel shipment will be reviewed by Bechtel l
r'eceiving inspection personnel.
i Based upon the NRC inspector's review of the audit and inspection findings and of the actions taken, this item appears to have been adequately addressed.
