2.
Site Tour The NRC inspector walked through various ccnstruction and storage areas to observe construction activities in progress and to inspect the general state of cleanliness and adherence to housekeeping recuirments. The tour included the Reactor Building, Reactor Auxiliary Building and the Fuel Handlina Building.
No violations or deviations were identified.

Follow-Up Actions Taken Following Arrests Related to Marijuana Use (PNO-RIV-81-09)
On March 17, 1981, Louisiana Power and Light Company (LP&L) informed Region IV of the arrest of eight individuals for drug related criminal conduct.
Eight construction workers at the Waterford, Unit 3 construction site were arrested and booked on charges of possession and sale of marijuana
'
by the St. Charles Parish Sheriff's Department ending a four month under-cover investigation. A preliminary inquiry revealed that subcontractor pipefitters, electricians and other craftsmen were involved.
No 0A/0C personnel were implicated. Of the eight workmen, only one, a welder, had l
been involved in safety-related work. The NRC inspector, by reviewing weld records, determined that the welder in question had been involved in the production of twenty-one pioing joints for the Safety Injection System. These included root passes, repair welds and completed welds.

The 'NRC inspector reviewed the radiographs. of fifteen of these welds to
,
verify that the quality of safety-related welds deposited'by the arrested
.;
.welderL had not been compromised. The results of the NRC review were com--
'
_
pared to the attendant radiographic interpretation sheets and found'to;
'be'in-accord. All.-twenty-one sets of radiographs:had been examined by
-
one Level II inspector _ from Tompkins-Beckwith (T-8) and another from.Ebasco...
-
Additionally, two LP&L'Ouality Assurance engineers had performed a review
of the' film between the time of the i. rests and the arrival of ~ the NRC.
-
-inspector-with the same'results.. It has been' determined, based on the above
.
-
. film reviews, that n'o substandard: safety-related work was performed by the
'[
arrestad welder. Without going-into; detail with the NRC inspector, an ~
f Ebasco representative stated that an ongoing program has been -initiated to
- minimize or eliminate.the possession,' sale.and use of any controlled substance at the Waterford, Unit No. 3 site. '
\\
No violations or' deviations were. identified.

- Status'of Previously Identified Items F
(Closed)1 Infraction-(50-382/80-03): Failure to Follow Insoection Procedures.
.h The NRC ' inspector reviewec T-B Procedure TBP-41, Revision D and verified that provisions are now includest to provide-a final visual inspection followino
.
- any NDE inspections; Inspection Form 11009 contains a signature block for QC' inspection personnel.. This signature now indicates that the-final visual
.r inspection was satisfactorily-performed. A review of T-B. surveillance records
indicates-that all Class 3 piping welds completed prior to the procedure
revision have been reinspected visually and that all meet the surft:e con-
!
dition requirements. The weld cited in the infraction (Drawing 8469-2516-R,
!
Isometric No.~5, FW-2) was visually re-examined by the NRC inspector. The
- _
- rejectable surface condition had been' adequately removed and the welded joint
'
- appeared to comply with the'ASitE Boiler and Pressure ' Vessel (B&PV) Code
!
requirements as stated in Section III, Subsection ND.

(Closed) Infraction (50-382/80-07): Failure to Verify Nonconformance with

!
Documented Drawings. The eight "D" stops identified in IE Inspection Report i
No. 50-382/80-09 were returned -to the manufacturer,-Industrial Engineerino i

'
designed configuration. The unrepaired parts were later returned to the l
site by IEW who stated they were not capable of performing the rework An

on.-site subcontractor, Gulf Engineering, agreed to make the required repairs j

This was j
l begun on December 30, 1980, and completed on January 9,1981. Gulf Engineering
documentation indicates that all ' work was accomplished by qualified welders and
,
'
was inspected by Peabody Testing personnel. The parts were subsequently l
inspected by Ebasco and LP&L personnel and found to be in conformance with l
Ebasco. Drawing 1654-9555, Revision 1 and IEW Drawing 2662Q-114, Revision 2.

Visual inspection by the NRC inspector was not possible as the cold-leo "D"
[
stops have been installed and are no longer accessible.

Field Changes to Engineering Drawings During the investigative review described 'in paragraph 3, a problem unrelated to the subject of the investigation was identified. The NRC inspector,'while reviewing radiographs. attempted to locate the individual weld joints on the isometric drawings.
Field Welds FW-016 and FW-017 were joints on the isometric drawings.
Field Welds FW-016 and FW-017 were represented by radiograohs, but a controlled copy of Isometric No. 886 for the Safety Injection (SI) system did not. indicate the location or existence i
of these welds. A check of isometrics in the engineering departments of-T-B and Ebasco gave no indication of the existence of these piping welds.
Interviews with cognizant perscnnel did nothing to clarify the situation.
.The NRC inspector and an LP&L QA engineering technician located the
, piping system and line in question and conducted a visual inspection of
.the identification numbers of each welded joint.
FW-016 and FW-017 were found; but their locations were designated as Shop Welds "D" and "G" on the isometric drawings.
By contacting the area welding supervisor, it was determined that two shop welds had been cut out, two field welds made in their place, and the as-built condition recorded.in red on the con-
'
struction copy of the controlled drawing..These changes were neither forwarded to files nor transferred to any other drawing.
'
Pre 5ently, changes are not made on other copies of the drawing until fabrication and installation are completed for the entire isometric.
Under given conditions, this is allowable under Ebasco Procedure ASP-IV-37, Revision I.
In i.his case, all steps taken were procedurally correct; however, the two field welds were made and inspected dur%g August 1980, with the only record of tne changes being retained in the construction area for seven months. Discussions with Ebasco and T-B engineering-revealed a general concurrence that this method, although allowed, is not considered to be. good practice. T-B verbally agreed to revise Procedure ASP-IV-37 to include a provision for T-B field changes to t,e made in the T-B engineering office, and to require that the file copy or
" stick drawing" of the isometric will also be modified to incorporate the changes at the same time.
In addition, T-B agreed to purge the constructicn areas of all single-copy, red-line drawings ud transfer all pertinent data to file copy drawings as soon as possible.
This will remain as an unresolved item entil verification of implementation of these changes can be made during a subseauent NRC inspection.
6.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, violations, or deviations.
One new unresolved item was disclosed during the inspection as discussed in paragraph 5 (failure to transfer field change records to file drawings).
