ASME Certification S stem TI 2512
Field fabrication and installation of nuclear service piping in all three Palo Verde units is governed by the 1974 Edition of the ASME Boiler and Pressure Vessel Code through and including the Winter 1975 Addenda.
Bechtel Power Corporation is the only construction organization per-forming work involving the fabri cation and installation of Palo Verde nuclear piping.
An ASME survey team visited the site on July 24-26, 1978 and evaluated the implementation and enforcement of Bechtel's quality assurance program being applied to code related wor k.
Based on the satisfactory findings of that survey, the ASME issued to Bechtel the following certificates of authorization:
1
certificate no.
N-1915-2 for the (N) symbol stamp certificate no.
N-1916-2 for the NA) symbol stamp certificate no.
N-1917-2 for the (NPT) symbol stamp Each certificate bears the authorization issue date of September 1,
1978 and the expiration date of September 1, 1981.
The inspector also verified that the activities being performed by Bechtel included the responsibilities defined in the applicable paragraphs of subsection 3000 of ASME Section III.

Safet Related Pi in Installation and Weldin a
~
Observation of Work and Work Activities Inprocess piping installation and welding activities were observed for Units 1 and 2.
These observations included pipe storage, cleanliness, rigging, fitup, tack, filler metal storage, welding, grinding and non destructive testing.
In addition the inspector ob-served the performance of two gC inspectors conducting tack, fitup and purge inspections prior to commencement of welding.
The pipe storage and cleanliness conditions were observed in the laydown/receipt inspection area, outside containment and inside Unit 1 containment and the Unit 1 and 2 auxiliary buildings.
All piping stored outside was on dunnage and the endcaps were inplace and taped to prevent entry of foreign material.
The pipe spools stored inside and awaiting installation wer e properly stored and protected from dirt as required by the applicable procedures.
The filler metal storage conditions, issue and disposition of unused material were observed by the inspector at Rod Rooms 2, 7, 6 and 10.
All filler metal was observed to be properly stored and issued in accordance with procedure HPP/gCI 100, Weld Filler Metal Control.
The Filler Metal Issue Logs for September 19, 1979 were reviewed and found satisfactory.
The inspector observed inprocess and completed welding on the following weld joints in the Unit 1 containment and Units 1 and 2 Auxiliary Building S stem or S ool PC-E-052-HCBA CH-283-HCBA S I-E-218-CCBA SI -F-157-CCBA SI-E-157-CCBA CH-N-087-GCBA CH-N-088-GCBA RC-A-051-BCAA SI-A-240-BCAA SI-E-236-CCBA SI-E-236-BCAA SI -E-157-BCAA 2SI-089-S-003 Fabrication Shop Pine Size 3 inch 3 inch 3 inch 3 inch 3 inch 3 inch 3 inch 16 inch 16 inch 3 inch 3 inch 3 inch 10 inch Weld No.

The welders were observed using the specified filler metal and were qualified for the process and positions being employed.
A liquid penetrant examination of weld 007 on line SI-A-240-BCAA was observed by the inspector.
The NDE technician conducting the examination was knowledgeable of the requirements of the procedure and performed the examination as required.
During the observation of piping and welding activities the inspector noted the cold springing of pipe on two occasion ~
Discussions with gC inspectors, cognizant licensee personnel, and review of procedures indicated that although the amount of cold springing allowed is specified in Specification 204, the item was not considered during gC inspections conducted by either the piping or welding gC inspectors and was not listed on the Construction Inspection Planning (CIP) record for piping.
The adequate control of the amount of cold springing and inspection by OC inspectors/Field Engineers is an unresolved item.

a.
Observation of Work and Work Activities Containment Liner (Unit 2)
Installed Unit 2 containment liner was examined to ascertain compliance with Bechtel specification 13-CM-370, "Installation Specification for Erecting the Containment Building Liner Plate System...".
In particular, rings 6, 7, 9, 10; 13, and 14 were examined for fitup, alignment, distortion, and location tolerance.
Vertical and horizontal seam welds for these rings were examined for coarse ripples, abrupt changes in thickness, and excessive undercut and reinforcement.
Evidence of welder identification was also observed.
In addition, a vacuum box in use was examined to determine calibration status
.
The field welding of Unit 2 dome liner plate segments into sections prior to installation was observed.
No deviati.ons or items of noncompliance were identified.
(2)
Polar Crane Brackets The installed Unit 2 polar crane brackets were examined and compared with applicable drawings and specification 13-CM-370.
Unit 3 polar crane brackets were observed stored in the out-side laydown area and met the storage requirements of ANSI N 45.2.2 for level D material.
No deviations or items of noncompliance were identified.
(3)
Steam Generator Lower Suppor ts and Safety Injection Tank Support.
The Unit 2 steam generator lower supports (both steam generators)
and safety injection tank support studs were exam-ined to ascertain compliance with specifications 13-CM-308 and 13-CM-365.
The steam generator lower supports were installed, but not yet grouted and the sliding base was not yet installed.
The safety injection tank support studs were in place and waiting placement of the foundation concrete.
No deviations or items of noncompliance were identified.
