Equipment stored at this area does not require maintenance during storage. The inspector observed that all items have been tagged " Hold" and were adequately stored.
No items of noncompliance were identifie.
.
7.
Steam Generator Supports The inspector observed unloading of the steam generator supports which had arrived at the site by barge and~their storage on wood blocking in an area adjacent to the reactor building.
The inspector discussed preparations for the lift with the responsible inspector and reviewed his partially complete Inspection Report HE-AA-0010 which showed proof tests of the lifting slings and shackle and NT of the hook. The inspector also examined the Eauipment Lift Record Cards (ELRCs) for the 4600 W crawler crane and the 4100 V ringer crane which were used for the unloading and storage.
The rigging, inspection, and records conformed to the requirements of:

.
Supports", which establishes requirements for ELRCs as a Class 'B'
specially designated lift.
FCP-702, " Rigging Guidelines" which designates the classification
.
of special lifts.
No items cf noncompliance were identified.
8.
Review of Deficiencies Reported by Vendors
.
During 1978 the Fairbanks Morse Engine Division of Colt Industries had reported deficiencies in its Type PC-2 Diesel Generators in accordance with 10 CFR 21. A number of these units have been furnished to or are on order for nuclear plants, including two units on order for the Beaver Valley 2 plant.
The deficiencies and corrective actions reported to have been taken consist of:
a.
Defects in fuel oil lines. This is written up on VSG N&D No. 23.
The oil lines have been replaced with a modified design. The engine was qualified by 300 start cests on Beaver Valley Unit B and other units.
b.
Defects in fuel injection pumps.
Injection pumps for all Engines were changed out. The engines were qualified by a 300 start test on a Seabrook Unit. VSG N&D No. 26 covers additional redesigned delivery valve springs.
c.
Defects in exhaust rocker arms.
The rocker arms were replaced on both BV-2 units.
Replacement of rocker arm on BV-2 Unit B is covered by VSG N&D No. 24. The units were qualified by 300 start tests on BV-2 Unit B and other units.
a
a
d.
Lube oil header failure. Redesigned lub oil headers were installed on all units. The units were qualified by 300 start tests on a Seabrook Unit.
' Additional deficiencies in the same units were reported by Colt Industries in 1380. These deficiencies and the corrective actions reported to have been taken consist of:
a.
Omission of oil plugs.
The omission resulted in an inadequate aupply of oil to the thrust bearings.
Inspection of the BV-2 units showed the oil plugs to have been installed and no corrective action necessary.
b.
Failure of engine thrust bearing. This failure was identified on a SNUPPS unit and was determined by the manufacturer to be due to in-adequate clearance between the bearing halves to allow for thermal expansion. The failed unit was modified and was shop and contract tested to qualify the modification.
However, a 300 start test was not conducted on this unit or any of the units modified for failure of the thrust bearing. The BV-2 units are being modified to the revised design requirements.
c.
Failure of adaptor in the air start modification package. This failure was reportedly due to excessive drilling while preparing the female part for threading which resulted in insufficient wall thickness.
These adaptors have been replaced on the BV-2 units.
This item remains unresolved pending review by an NRC inspector of corrective actions taken and justification by the licensee for lack of requalification of the units by a 300 start test following replacement of the failed thrust bearing or performance of this test.
9.
Review of Nonroutine Events Reported by the Licensee On May 21, 1980, the licensee submitted a revision to their report of a significant deficiency which had been submitted in accordance with 10 CFR 50.55(e). The revision reported identification of 20 No. 11 bars of rein-forcing steel which had been omitted from a 10 foot section of a cubicle wall which frames into the crane wall.
The inspector examined an internal DLC-SQC memorandum which recommended that, in view of the reinforcing steel discrepancies on the crane wall a similar review be performed for all Category I concrete.
The initial review was limited to the reactor building.
The missing cubicle wall steel was identified and documented on N&D No.1204. Thereafter a random i
review of all Category I concrete placements was instituted. This review
.
is'still in progress. No additional nonconformances have been identified to date.

The inspector had previously reviewed documentation and corrective actions concerning-this item during Inspections 79-08, 79-09 and 80-03.
The inspector examined N&D No.1204 which had been dispositioned, corrected and signed off; and also examined results of the service building concrete review.
The inspector had no further questions concerning this item.
10. Licensee Actions on Previour Inspection Findings (Closed) Unresolved Item (80-02-01):
Performance of internal audits by Power Piping Company (PPC). The inspector reviewed PPC Procedure AP-1,
" Procedure for Scheduling, Planning, Performing, Reporting and Documenting Management QA Internal and Vendor Audits and Reporting and Documenting External Audits". This procedure requires the use of Corrective Action Requests (CARS) to correct discrepancies identified during audits.
The DLC Audit No. DC-2-80-20, conducted during May 29-June 3,1980 verified the actions taken to correct the CARS identified durirg the 1979 PPC manage-ment audit.
In addition, the inspector verified that S&W had audited PPC QA program during July 20-27, 19/9 and had audited corrective actions on January 18, 1980.
The inspector had no further questions concerning this item.
(Closed) Unresolved Item (80-02-02):
PPC training prot, ram not adequate.
The inspector discussed the PPC training program, corrective action to correct the discrepancies identified during 1978, and reviewed a matrix developed by PPC to show the training required for each QC assignment.
During DLC Audit No. DC-2-80-20, the auditors had reviewed the training requirements of QC and production personnel and had audited the corrective action by PPC including a PPC audit of training conducted March 31-April 1,1980.
The inspector had no further questions concerning this item.
11.
Exit Interview The inspector met with licensee and contractor representatives (denoted in Paragraph 1) at the conclusion of the inspection on July 10, 1980.
The inspector sumarized the scope and findings of the inspection as described in this report.
