Site Tour The IE inspectors toured the Unit 1 Containment and Mechanical /Electricai '
Auxiliary Buildings, the Level B and C Warehouses, and the cable storage yard to observe activities in progress and to inspect housekeeping.
No items of noncompliance or deviations were identified.
3.
Reactor Coolant Pressure Boundary Piping and Cther Safety-Related Piping ' Units 1 and 2 The IE inspector determined, by observation of work activities in the Mechanical / Electrical Auxiliary Building for Unit I and the Reactor Containment Building for Units 1 and 2 and review of welding material requistion records issued from three Material Distribution Stations (MDS-2, -3, and -4), that the stop-work order for E&R welding was being effectively implemented.
In the areas inspected, no welding of safety-related materials or components was observed.
No items of noncompliance or deviations were identified.

Reactor Containment Liner Dome - Unit 2 The IE inspector observed the welding and related activities of the Pittsburgh-Des Moines Steel Company for installation of replacement , stiffeners onto the reactor containment liner dome. Welding was observed being accomplished on stiffener weld No. 7 identified on Drawing E80B/0 for Course 2RD, Assembly S4-8, Seam B, and stiffener welds No. I through , 11 identified on Drawing E78AB/0 for Course 2RB, Assembly S2-5 to S2-9, Seam 25.
Welder 008 was welding on stiffener weld No. 7 while welder , 156 was welding on stiffener welds No. I through 11.
Both welders were using electrode type E7018 (ID 13601) as required in Welding Procedure Specification (WPS) 67-61, Revision I for the shielded metal-arc welding process.
The welding electrode identified with ID 13601 was traceable to a Certified Material Test Report representing electrode type E7018 of Lot No. 22926 and having chemical and mechanical properties consistent with requirements of ASME Section II, Part C, SFA 5.1 for type E7018.
The welding of the stiffeners was being monitored by a Level II QC inspector. The documentation for visual acuity and Level II certification for the QC inspector was reviewed and found to be current.
No items of noncompliance or deviations were identified.
5.
Electrical Cable and Raceway Installation The IE inspector reviewed QA procedure SI-QAP-2.3, " Examination and a.
Certification," and the training and certification records for all of the electrical QC personnel.
The licensee had initiated a memorandum to Mr. Warnick (B&R) from L. D. Wilson (HL&P) defining five areas of concern related to the recent certification of QC inspectors. The site discrepancy memo
D-032, dated April 16, 1980, requires a response by May 7, 1980.
! During the IE inspector's review of the electrical QC certification
j records, it was noted that a number of the inspectors did not have
four years of previous testing and/or inspection experience as required for Level II certification by paragraph 3.1.2 of ANSI N45.2.6-1973, " Qualification of Inspection, Examination, and Testing Personnel for the Construction Phase of Nuclear Power Plants."
At the present time, the Level II certification of electrical QC inspectors allows one hundred percent credit for previous inspection experience, fifty percent credit for previous electrical craft experience, and the utilization of proficiency testing vhere the total experience level does not meet the total four year require-ment of ANSI N45.2.6 - 1973, paragraph 3.1.2.
This standard allows

The proficiency tests are administered by corporate Level III inspectors and were not available on site.
The IE inspector reviewed the answer sheets and test results, but was not able to review the actual test questions to determine if the tests were actually a measure of proficiency for the electrical inspectors who do not meet the experience requirements of ANSI N45.2.6 - 1973.
, This is considered as an unresolved item pending the IE inspectors review of the six different tests that were administered for pro-ficiency qualification of Level II QC inspectors during April 1980.
b.
The IE inspector reviewed the Nonconformance Report (NCR) and Corrective Action Report (CAR) Logs for the previour eighteen months.
Six NCRs and two CARS were reviewed to determine if the nonconformances were properly identified, and if the corrective action was both appropriate and timely.
No items of noncompliance or deviations were identified.
The IE inspector reviewed the following procedures and drawings for c.
compliance with 10 CFR 50, Final Safety Analysis Report, and appli-l cable industry standards: A040KP ECP-6, Revision 4, " Electrical Installation" , A040KP ECP-9, Revision 5, " Cable and Raceway Installation Documentation" E-0-100 through E-0-109 Electrical Installation Notes and Details The IE inspector was informed by the responsible Quality Engineer (QE) that the above listed procedures and drawings are presently under review and revision, based on the learning process being developed through the use of these procedures and drawings in nonsafety-related applications.
The IE inspector observed the pulling of nonsafety-related cables and discussed with the QE several areas of concern in the above listed procedures and drawings and their application. The QE was aware of these areas of concern and had already initiated appropriate actions.
No items of noncompliance or deviations were identified.

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or deviations.
An unresolved item related to training of electrical inspectors is discussed in paragraph 5.a.
7.
Exit Interview The IE inspectors met with licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on May 8, 1980, and summarized the purpose, scope and findings of the inspection.
