' Plant Tour (Units 1 and 2)
A tour of the site was made to observe the status of the work and contruc-tion activities in progress.
The inspectors examined work items for any obvious defects or noncompliances with regulatory requirements or license conditions.
Areas observed included:
storage of piping and structural steel in the laydown areas; the status of form work and rebar installation in Unit 2; and preparation for placement, placement and testing of con-crete for the RPV support pedestal.
No items of noncompliance were identified.
3.
Hanger Installation During a walk-thru inspection the inspector noted hanger 1-PBE-049-H07 was not installed correctly.
The hanger was installed such that contact with 4 supporting lugs was not possilbe.
Only two of the four lugs mated to the hanger.
After further review it was found that the hanger is classified as non "Q".
The hang 7r supports the condensate return line which is Non "Q".
However, it also appears to provide some support for a "Q" listed line which connects to the condensate return line below the hanger.
For that reason the inspector questioned classification of this line as Non "Q".
Information was not available on site to resolve this question.

Piping Documentation a.
The inspector examined documentation for the items listed below for conformance to the requirements of the following:
Specification 10855-P-201(Q), Rev. 3, " Technical Specification
.
for Shop Fabricated Piping for Nuclear Service" Specification 10855-P-202(Q), Rev. 3, Add.1, " Technical Specif-
.
ication for Field Fabrication and Installation of Piping for Nuclear Service" Specific Work Plan / Procedure SWP/P-P-108, Rev. 0, " Fabrication,
.
Alterations and Modification of ASME III Components" SWP/P-P-54, Rev. 0, " Installation of Process Pipe Systems"
.
QCI-P-1.10, Rev. 3, " Piping Subassembly Fabrication, Installa-
.
tion and Rework" QCI-R-1.00, Rev. 5, " Receiving Inspections.
.
The examination covered vendor manufacturing, inspection, NDE records, manufacturers quality release forms and receiving inspection reports for the following items:
Spool pieces No. 1-BE-047-S03 and 1-BE-047-SO4 for the core
.
spray system Expansion Joint No. 1-XJQ-30 and spool pieces No. 1-BE-019-SO9,
.
1-BC-044-S09, 1-BC-044-510, 1-BC-088-S04 and 1-BC-088-S05 for the RHR system Spool piece No. 1-BJ-001-S01 for the HPCI system
.
Spool piece No. 1-FC-007-501 for the Reactor Core Isolation
.
Cooling System.
b.
The inspector also examined Nonconformance Reports (NRC) concerning piping which had been written during the period January to to July, 1979.
The inspector observed that five of the ten NCR's written during this time concerned wall thickness less than the minimum specified.
This item was discussed with representatives of the licensee and the inspector was informed that an investigation was in progress to determine the extent and significance of this problem.

The results of this investigation will be reviewed by an NRC inspec-tor during a subsequent inspection.
No items of noncompliance were identified.

Visua1 Examination of Safety Related Welds The inspector selected (5) five completed welds in the core spray line and performed a visual examination to determine whether the following characteristics conform to the applicable code, construction spacification, and the contractor welding procedure.
Weld surface finish and appearance, and weld location length size
.
and shape Weld reinforcement height and transition between different wall
.
thickness Joint configuration
.
Surface defects
.
The welds were audited visually for compliance with the ASME Boiler and Pressure Vessel Code,Section III Winter 74 Addenda.
No items of noncompliance were identified.
6.
Welding Specification and Procedure Qualification Review The inspector examined Bachtel welding specification P1-AT-LH Revision 1 and associated procedure qualifications, P.Q.R.8, 17, 17A and 18 to ascertain whether they conform to Chapter 17 cf the SAR and Section IX of the ASME B&PV Code.
The following specific areas were reviewed.
Welding specification contains all essential variables, supplementary
.
essential variables and nonessential variables.
Welding specification details applicable preheat, interpass tem-
.
perature and port weld heat treatment.
Essential variable limits are controlled and consistent with Sec-
.
tion IX of the ASME Code.
Mechanical tests have been performed and are within acceptable ranges.
.
Changes and revisions of essential variables are supported by requa-
.
lification and are properly identified by revisions.
No items of noncompliance were identified.

Welding Material Control The ir.:pector examined the Bechtel weld control station to ascertain con-formance with covered electrode storage controls.
This included a review of the material certifications for welding materials held in heated ovens and ready for issue.
The fo: lowing items were audited.
Selectively sampled and reviewed welding materials purchasing and
.
receiving records to determine if required test were performed on covered electrodes for the following electrodes:
--
P0F5781, HT-421C4281 Lot 02-3-E824S 1/8" dia.
E7018 electrodes P0F5781, HT412A7671
--
Lot 02-2-E703P-KB 3/32" dia.
E7018 electrodes Determine whether welding material storage procedures contain require-
.
ments for moisture control, and specify holding times and temperature and assure actual practices follow tha requirements.
Determine whettier distribution of welding materials are controlled
.
in accordance with approved procedure and unused electrodes are returned and placed in holding ovens.
All areas reviewed met the applicable procedure for procuring, storing, issuing, and returning electrodes.
No items of noncompliance were identified.

The review included chemistry analysis, yield and tensile strength and nondestructive examinations where applicable.
No items of noncompliance were identified.

Licensee Action on Previous Inspection Findings (Closed) Noncompliance (79-03-01):
Failure to cap containment piping penetrations in storage and after installation.
The inspector reviewed CAR No. 22280 issued by PDM which required capping of all penetrations and Bechtel letter BLP-#38, 385 which states that the required corrective action had been performed.
(Closed) Unresolved Item (79-03-03):
Specification for weld surface cleanliness. The inspector examined PDM Specification WS-3.
Revision
"V" to this specification deletes the reference to SSPC-3. This
-
clarifies the requirunent for weld surface cleanliness.
10.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, or items of noncom-pliance.
An unresolved item identified during the inspection is discussed in Paragraph 3.
