Inspection on November 6-8,1979 (Report No. 50-412/79-08)
Areas Insjected:
Routine, unannounced inspection by two regional based inspectors.
Tiid-iiispectors examined the QC programs for handling and installation of safety related piping; and for receipt, storage, handling, and installation of pipe hangers and supports; and, review of the status of outstanding items.
The inspection involved 40 inspector-hours on site by two NRC regional based inspectors.
Results: Of the two areas inspected, no itens of noncompliance were identified in one area and one iten of noncompliance was identified in one area (Infrac-tion - failure to comply with specifications for preservation of oipe hangers and supports while in storage, Paragraph 3).

Plant Tour The inspector made a tour of the site to observe work activities in prog-ress, completed work and construction status.
Work items were examined for obvious defects and for evidence of noncompliance with regulatory requirements and licensee commitments.
Evidence of QC activities and qua-lity control of the work was observed.
Specific activities observed by the inspector included observation of installation and welding of piping; and, removal of improperly placed concrete in crane wall.
3.
Storage of Pipe Hangers and Supports The inspector observed storage of pipe supports and restraints fabricated by Power Piping Company in storage at area "L" located in Shippingpor.
Storage area "L" is a controlled access outside or Level D type storage area as stated in 2BVS-981, Stone and Webster's Design Specification for storage and maintenance.
Conditions observed included storage of variable spring hangers and threaded portions of hanger assemblies unprotected from the weather resulting in rusting of these items.
Duquesne Light Company (DLC) Site QC (SQC) Receiving Inspection Plans (RIP)
59-R2 and 59-2-R2 require that variable spring hangers be stored in accord-ance with Level C requirements - Level C being inside unheated storage.
Stone and Webster Design Specification 2BVS-59, " Design and Fabrication of Power Plant Piping Supports," Revision 0, states in the " Shop Painting" section that threads and machined surfaces of piping supports shall be coated with a preservative.
Additionally, Attachment 3 to 2BVS-981 requires that fabricated piping supports be recoated, repainted, or resealed as necessary during storage.
RIP-59-2-R2 and RIP-59-R2 do not specify the requirement to recoat, repaint, or reseal threaded portions of piping supports as necessary prior to storage.
There is a requirement in 2BVS-981 to maintain the preservative on the threads during storage, however, there is no maintenance history card in the maintenance system to either keep a record of inspections or to remind the licensee to perform a periodic inspection.
The improper storage of variable spring hangers, the lack of preservative on threaded portions of the hanger assemblies, the lack of a requirement to verify preservation prior to storage, and the lack of an effective pro-gram to maintain preservation during storage is an item of noncompliance relative to Criterion XIII of Appendix B of 10 CFR 50 (412/79-08-01).
4.
Rebar Omitted From Crane Wall Concrete Placement The licensee had reported as a significant deficiency that twenty-eight No. 11 "J" bars and seventy-eight No. 4 shear bars had been omitted from a concrete placement for the crane wall at elevation 755' 10" to 762' 5" between approximately azimuth 97 to 134.
The inspector examined N&D No.1159 which identified this nonconformance and prescribed a partial disposition.
The final disposition will be pro-vided following removal of the concrete in the nonconforming area.
The inspector also examined the applicable drawings and discussed the cause and resolution of the nonconformance with the licensees representative.
This item will be reviewed following corrective action.
5.
Installation of Safety Related Piping The inspector observed installation, handling, and protection of pipe spools CCP-473-2 and 473-3, SIS-5-5A and 5-6, and CHS-423-1 during various stages of installatio.
.
Records examined showed issuance and use of proper materials; cleaning in accordance with applicable procedures prior to use; performance of pre-scribed NDE activities; and, use of calibrated and controlled Measuring and Test equipment.
The inspector reviewed experience, training, and qua-lification records of inspectors assigned to this work.
The inspectors had been qualified for their assigned duties.
Installation, handling, and protection of pipe conformed to the requirements of the following:
Specification 28/S-920, Revision 4, " Field Fabrication and Erection
-
of Piping ASME Section III, Classes 1, 2, and 3 and ASNI B31.1.0, Class 4."
Field Construction Procedure FCP 205, dated March 16, 1979, " Scheduling
-
and Monitoring Piping Systems, Piping Materials, and Piping Supports."
FCP-221, dated June 2, 1978, " Cleaning and Maintaining the Cleanliness
-
of Piping, Tubing, and Associated Components."
Inspection Procedure IP-7.2.2, "ASME Section III Class 2 and 3 Buttwelds."
-
No items of noncompliance were identified.
6.

The QA implementing procedures address the specific areas of audits and their frequency, control of design and field changes, in process and final QC inspection, contractor QA programs, and procurement document require-ments for technical adequacy, pertinent acceptance criteria, and sufficient documentation.
The inspector verified that the work procedures specify support / restraint spacing and clearance requirements, welder and weld procedure qualifica-tion requirements, methods of identification, requirements for integral and nonintegral attachments to supported pipe, cold and hot adjustments of constant and variable load supports, use of updated drawings, and require-ments for integrity of threaded connections.
No items of noncompliance were identified.

Review of Nonroutine Events Reported By the Licensee By letter dated January 19, 1979, the licensee reported cracking of the reactor containment liner plate at an overlay pad at elevation 719.
A final report of the analysis of this failure including a metallurgical study and tests by S&W, an investigation of the problem by an inde-pendent consultant and a review of the liner plate serviceability by a second consultant was submitted to the Region I office of the NRC Office of Inspection and Enforcement and has been reviewed by that office.
The inspector examined N&D No. 9167A which had been closed on October 18, 1979, and inspection reports of surveillance which verified weld repair and grouting behind pad.
The inspector had no further questions concerning this matter and this item is resolve.

Potential Defects in NEMA Size 3 Starters and Contactors By letter dated September 13, 1979, Gould, Inc. had reported, in accordance with 10 CFR 21, defects in their NEMA Size 3 Motor Control Starters and Contactors.
This report indicated that some of this equipment may have been shipped to Beaver Valley Unit 2.
This information was also furnished directly to the licensee.
The inspector reviewed documentation on site which showed that a review of receiving records identified no NEMA Size 3 assemblies as having been received on site, transferred to off site storage or transferred to Unit 1.
Some NEMA Size 2 starter assemblies had been received.
Discussions by the licensee with representatives of Gould, Inc. confirmed that the Size 2 assemblies were not affected by this problem and also that Gould, Inc. had secated the NEMA Size 3 assemblies ordered for this project and would correct the problem or replace them prior to shipment.
The inspector had no further questions concerning this matter.
9.
Licensee Action on Previous Inspection Findings (0 pen) Unresolved Item (79-05-03):
Requirements for NDE of sleeve to forg-ing welds of flued head penetrations.
N&D No. 9169 has been dispositioned to provide for radiographing these welds as required by the ASME III.
One weld in a penetration which has been cut out for other reasons has been radiographed for technique approval.
The results are considered acceptable and the technique has been approved.
This item remains unresolved pending completion of radiography and repairs as necessary and review of the results by an NRC inspector.
10.
Exit Interview The inspector met with licensee and contractor representatives (denoted in Paragraph 1) at the conclusion of the inspection on November 8, 1979.
The inspector summarized the scope and findings of the inspection as described in this report.
