Licensee Action on Previous Inspection Findings (Closed) Noncompliance (50-498/79-13; 50-499/79-13):
Pittsburgh-Des Moines (PDM) (site) Failed to Maintain QA Manual Per Procedures.
The RRI reviewed Section 16.5 of the new manual and found that it described the use of supplements for site specific QA manuals.
This item is closed.
(Closed) Noncompliance (50-498/79-13; 50-499/79-13):
Failure to Describe How Auditors are Qualified. The RRI reviewed Section 15.6 of the PDM QA manual, which now describes the basis of auditor qualification.
This item is closed.
(Closed) Noncompliance (50-498/79-13; 50-499/79-13):
Failure to Properly Maintain PDM Manuals 16, 132, 152 and 177. The RRI determined that the QA manuals were reviewed and corrected.
This item is closed.
(Closed) Noncompliance (50-498/79-13; 50-499/79-13):
Failure to Follow PDM Audit Procedure.
The RRI reviewed the missing audit (77-202) and verified that annual audits had been performed.
Corrective action blocks had been signed on torms sent to the site file. Audit 77-202, which was missing from the file during the inspection, also indicated that reaudit had been accomplished. The recurring deficiency, reported in audit 79-203, was in error and should not have been reported as an audit finding.
This item is closed.

(Closed) Noncompliance (50-498/79-13; 50-499/79-13): Faihire to Delineate Organizational Changes in the PDM QA Manual. tus RRI verified that PDM organizational chart, page 0.7, Rev. 6 (8-2-79) properly described the organizational structure.
This item is closed.
(Closed) Unresolved Item (50-498/79-13; 50-499/79-13): Qualificatica of PDM Inspection Personnel. The RRI verified that current inspector personnel were qualified in accordance with commitments.
This item is closed.
(Closed) Unresolved Item (50-499/79-15):
Protection of Concrete Placements from Weather. The RRI was informed that the applicable construction procedure was revised. However, the Region II NRC Inspector found the revision to be unacceptable in NRC report Nos. 50-498/79-19; 50-499/79-19.
Therefore, this matter is considered closed relative to report 79-15, and remains an unresolved item in report 79-19.
This item is closed.
3.
Site Tours The RRI inspected various areas of the site, which included the following:
Units 1 and 2 Reactor Containment, Mechanical, Electrical Auxiliary and Fuel Handling Buildings; various laydown areas; and Essential Cooling Pond areas.
The RRI identified and informed the licensee of isolated storage / handling conditions, which were considered minor deficiences. However, "on the spot" corrective action was taken, and the RRI has no further questions regarding this matter at this time.
No items of noncompliance or deviations were identified.
4.
Safety-Related Piping (Welding)
The RRI reviewed the app sie NDE reports and inspected radiographs of the following field wel<
n Reactor Containment Building (RCB) No. 1:
Residual Heat Removal ystem Field Weld No.
'
RH 1304 FW0002 Safety Injection System Field Weld No.
SI-1206 FW0019 SI-1106 FW0049 SI-1105 FW0017 SI-1205 FW0017

.
The RRI located each completed weld and observed the quality of the final pass as well as the surface condition relative to interpreting radiographs.
The RRI reviewed the weld data card for Unit 1 Weld No. 0002 in RH Line No. 1304-KB for compliance with requirements with ASME III, Class 2.
Data on the card included identification of the drawing and specification, specification of base and filler materials and completion of the required inspections.
No items of noncompliance or deviations were identified.
5.
Containment Structural Steel Welding The RRI visually inspected the following welds made on the liner plate for RCB No. I dome:

Welders 109 and 168 were using 1/8" and 5/32" E7018 welding rods, respectively, l
and the current coming from each power source was checked to assure that l
the specified amperage was used.
The tongs used to check amperage had been calibrated and were next due for calibration on May 13, 1980.
Preheat, polarity, welding rod material and size were as required by procedure.
One very small area on one seam exhibited excessive weave on the cover pass. This was discussed with the PDM Site QA Manager who stated he would look into the cause of the excessive weave. He also stated that the area will be repaired.
Since the area was so small, in comparison to the total area welded, the inspector had no further questions on this matter.
No items of noncompliance or deviations were identified.

Follow Up on Construction Deficiency (10 CFR 50.55(e))
The RRI reviewed and inspected several construction deficiencies as follows:
a.
RCB-2 Liner Plate Bulae Repair
,
The RRI observed the start of repair of the liner plate. The vertical
stiffeners (3" angle iron) had pulled away from the 5" horizontal
,
channel, when the overpressure bulged the liner plate. The maximum bulge appeared to be approximately 4" toward the center of containment.
The concrete between the 3" angle iron (on 15" centers) failed.
The concrete just below the top 8" horizontal channel was found to be honeycombed adjacent to the void.
The honeycomb area was approximately 8-10" in height and extended 3-4" into the wall.
b.
Excessive Hydrostatic Pressure Under the Essential Coolina Pond The RRI reviewed the licensee's final report relative to excessive pressure. After evaluation, tha licensee considered the item not to be reportable within the context of 50.55(a).
The pond was observed to have had approximately two feet of water added to counter the potential hydrostatic pressure reported.
This matter is considered closed.
c.
Voiding in Unit 1 Lift 15 The RRI reviewed the configuration of horizontal and vertical stiffeners welded to the liner plate to determine the original and present design.
The following drawings were reviewed:
Unit 1 Unit 2 2-C-26-1-S-1004 (Rev. 0-3)
2-C-26-2-S-1004 (Rev. 0-2)
The purpose of the review was to determine if the toes of the 8" horizontal channel pointed up or down. Review of the drawings established that the channels pointed up in all cases and, therefore, would not have contributed to the void.
7.
Pittsburah-Des Moines Central QA Program The RRI reviewed selected portions of the subject program as follows:
Area Comment Organization The present staff consists of a QA manager, an inspector, 9 welders, 2 helpers and a foreman, a superintendent, and a site engineer.

Area Comment Design The Engineer Corrective Action Request (ECAR)
log was reviewed including ECAR Nos. F-63 (6-13-79) to F-86 (4-17-80).
Only one outstanding ECAR was noted.
Personnel Qualifications The Welding /NDE Inspector files need to be updated.
,Nonconformances The Nonconformance (CAR) log was reviewed for the period 1-1-79 to present.
Audit Audit No.80-203 had been performed by PDM Corporate office.
No findings were recorded.
