- Attended exit interview 2.
Exit Interview On June 5, 1980, the inspector met with the licensee representatives noted in paragraph 1 above and summarized the scope and findings of the inspection of safety-related pipe welding and steel structures within the containment.
The status of noncompliance 556-56 /80-03-01 was discussed and the licensee agreed to further evaluate the 95 radiographs reviously rejected and later accepted by CB&I. The licensee was informed ti.at this inspection resulted in no new items of noncompliance or deviations.
3.
Licensee Action on Previous Inspection Findings (0 pen) Infraction, 566/567/80-03-01, Failure to establish adequate measures to control radiography.
All re-radiography detailed in the TVA letter of response dated April 28, 1980 had not been completed at the time of the inspection.
The inspector reviewed the licensee corrective actions taken to date. This included a review of a sample of re-shots plus a review of a sample of the 95 film originally nonconformed by CB&I and later accepted. During review

of the sample from the 95 film, the inspector noted one radiograph (ASSY.
A7, sm. A2, interval 38-39) where the shim appeared to be in the weld. This film needed further evaluation to determine whether the shim was in the weld.
The licensee agreed to further evaluate the 95 film originally nonconformed and later accepted by CB&I. This item will be examined further after all licensee actions have been completed.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort The following areas of interest were examined by the inspector:
a.
A general plant tour was made and general construction activities observed in the following areas:
-
Reactor Building (Units 1 and 2)
Waste Management Building
-
i
-
Fuel Building (Units 1 and 2)
l Fabrication Shop
-
-
Stainless Shop
-
Pipe Shop b.
Two TVA welders were observed in the process of qualifying; one on test GT-7-0-1-L(a) for stainless pipe welding and one on test SM-4-H for carbon steel plate.
The inspector observed completed safety-related piping welds 2VA0151, c.
2VA00137, 2VA00180, 2VA00124 and 2VA00123 on weld map 2VA0011 in the final welded condition.
Safety-related piping is being welded in accordance with the ASME Boiler aad Pressure Vessel Code,Section III,
!
1974 Edition including the summer 1976 addenda. Weld appearance and size were examined.
d.
Rod Room # 1 was examined for control of storage, issue, and temperature.
,
The inspector reviewed QCIR No. 23340 which covers rejectable welds on e.
control building structural steel furnished by Mississippi Valley Steel Company. The welds were rejected at receipt inspection for undercut, under size fillets, porosity, overlaps and generally poor surface con-ditions. The inspector observed a sample of the rejectable conditions.
At the time of the inspection, this problem was being evaluated for reportability to the NRC. This item will be identified as Inspector Followup Item No. 566/80-09-01.
Within the areas inspected, no items of noncompliance or deviations were identified.

Steel Structures and Supports - Welding Procedure Specifications (Unit 1)
.
The inspector reviewed CB&I containment Welding Procedure Specifications (WPS) and quality assurance procedures to determine whether specifications and procedures have been established, qualified and controlled in accordance with NRC requirements, SAR commitments, licensee's QA program, and ASME code requirements, as applicable. The applicable code for this welding is the ASME Boiler and Pressure Vessel Code,Section III, subsection NE, 1974 Edition with addenda through the summer 1976. Any changes made since the last review (See IE:RII reports 566/567/79-13 and 566/567/7a-17) to the following procedures and specifications were reviewed:
a.
" Nuclear Quality Assurance Manual For ASME Section III Products" Division 4, Section 8 b.
Welding Procedure Specification E7018/74200 c.
Welding Procedure Specification EH-14 (Twin)/860 0. D./74200 d.
Welding Procedure Specification EH-14/860 0. D./74200 e.
Welding Procedure Specification E705-2/E7018/74200 Within the areas insepcted no items of noncompliance or deviation were

Steel Structures and Supports - Welding Material Control (Unit 1)
i The inspector reviewed any changes made to the CB&I program for control of welding materials since the last review (see IE:RII reports 566/567/79-13 and 566/567/79-17). See paragraph 6 above for the applicable code.
The following specific areas were examined:
a.
" Nuclear Quality Assurance Manual For ASME Section III Products" Division 4, Section 8.2 including Supplement I b.
Material identification c.
Welding material issue station d.
Welding material receiving records for the following materials were reviewed for conformance with applicable procedures and code require-ments:
(1) Submerged Arc - EH-14 Wire: Ht. 036152 Flux
- Lot H H (2) Shielded Metal Arc - 1/8" E7018: Ht. 412E7191 5/32" E7018: Ht. 401H0741

Steel Structures and Supports' - Observation of Welding Activities Within Containment (Unit 1)
The inspector observed in process welding activities of containment structural
.;
field welds as described below to determine if applicable code and procedure
'
requirements were being met.
See paragraph 6 above for the applicable code.
