Licensee Action on Previously Identified Items
.
(Closed) Unresolved Item (77-07-03): Screenhouse (Service Water Pump Structure) housekeeping was poor.
,
The inspector verified that the licensee has taken appropriate action to attain and maintain an acceptable level of cleanliness in the service j
water pump structure.
l 3.
Fuel Receipt and Storage
{
The inspector verified the integrity of the security controls for the new fuel storage area, and that provisions for control of the new fuel
!
storage environment were in effect. The inspector noted~that the j
ventilation plug for the drywell head area was unsecured and available for use as emergency egress from the upper levels of the drywell. A a
j second watchman was being utilized on the refueling floor to maintain access control at this point.
No items of noncompliance or deviations were identified.

Followup on the Quality Confirmation Program i
a.
Review of Voided Nonconformance Reports
>
The inspectors reviewed an additional 27 essential nonconformance
reports (NRs) which had been " voided" rather than " superseded."
>
The review consisted of determining if the exact problem described
!
!
on the original (voided) NR had been copied on the superseding NR.
I The review was performed after each voided NR and superseding i

!-
document had been submitted to and approved by a review committee per Procedure 15-QA-04, Revision 0, " Review and Processing of Voided Nonconformance Reports."
The inspectors determined that the exact problem found on NR E-131 had not been copied on Revision 1 to E-131.
The original NR identified a gouge in a steel plate, whereas Revision 1 identified a procedural problem (i.e., the gouge was repaired using a procedure.which was not qualified to repair the depth or total thickness involved). The licensee agreed that the exact problem had not been copied on the superseding document and stated that the problem would be dispositioned on a new nonconformance report.
In addition, the inspectors identified a concern with the dir-position of NR E-861, Revision 1, which superseded the origina?
voided NR E-861.
The concern was two-fold:
(1) The NR identified a problem with defective pipe supplied to the site by a vendor which was known by the inspectors to have supplied other pipe with similar defects in the recent past. The licensee stated that this would be looked at under their vendor program.
(2) The amount of pipe shown in the disposition to have been installed in plant systems and the amount of pipe shown to have been ultrasonically tested in the field per the dis-position were not identical. Approximately 200 feet of questionable pipe appeared to have remained installed in plant systems without having been subjected to.the required ultrasonic testing.
These concerns are considered to be open items and will be followed up in a future inspection (50-358/81-29-01).
b.
Review of Weld Test Program The inspector observed the performance of a test program con-ducted by the licensee to determine if visually rejectable weld defects could be detected through a thin (1-3 mils) coat of galvanox paint.
The licensee reported that final results from the test program were indeterminant and that no further effort would be expended on this program at this time. Therefore, the licensee will remove all paint from all weld surfaces prior to performance of visual weld examination.
c.
Review of Overall Quality Confirmation Program Administration The inspector commenced a review of the administration of the QCP. This review is continuing and will be the subject of a future inspection report.
No items of noncompliance or deviations were identified.

Observation of Graded Emergency Exercise The inspectors participated as part of the NRC team inspection of the Zimmer graded emergency exercise. The finding: of that team inspection are the subject of Inspection Report No. 50-358/81-30.
.
6.
Plant Tours The inspectors conducted frequent plant tours throughout this inspec-tion period. The below listed items were identified and the licensee is taking or has taken appropriate corrective action:
,
a.
Two WR System isolation valves (1WR020 and 1WR011) were found to have one or more retaining bolt nuts backed-off at the motor to motor-operator housing connection.
In one case this resulted in leakage of lubricating oil from the drive motor.
b.
Ten pieces of E7018 weld rod were found lying uncontrolled in the drywell, elevation 535'.
The Site Weld Manager stated that the weld rod (as identified by lot number) had not been recently issued. Weld rod issued under the present system, which includes both rod and stub counts at issue and return to the rod shack, would be traceable directly to the responsible welder.
c.
Appropriate steps had not been taken to control the cleanliness of heat exchangers for the VX and VC systems. This was brought to the attention of an H. J. Kaiser QC Inspector who immediately rectified the condition.
The piping to these heat exchangers was being reworked under an engineering change request (ECR) which referenced NR E-2433. The items identified as nonconforming on the NR had not been tagged per Procedure QACMI G-4, "Nonconformances," and the disposition had not been accepted by the Material Review Board prior to
j commencement of rework. This was brought to the attention of the Kaiser QA Manager.
No items of noncompliance were identified.
7.
Management Exit Interview The inspectors met with licensee representatives (denoted in Paragraph 1)
at the conclusion of the inspection on December 1, 1981. The inspectors
'
summarized the scope and findings of the inspection.
