Observation of Electrical Work Activities a.
The RIII inspector observed the following installed conduit hangers as located per S&L drawing No. E30-1004-01A-E1H, Revision D:
Hangers JS-F-2 JS-F-3 TS-1A TS-1B JB-2 JS-5 Where applicable, the above supports were installed in accordance with Baldwing Associates Traveler No. E30-1004-0A-JS-F-2, Revision 1, No.
E30-1004-01A-JS-F-3, Revision 1; No. E30-1004-01A-TS-1A, Revision 00; No. E30-1004-01A-TS-1B, Revision 00; No. E30-1004-01A-JB-2, Revision 00, No. E30-1004-01A-JS-5, Revision 00.
The components, dimensions, tolerance, number of assemblies and spacing were as specified except as follows:
(1) The inspector observed the traveler for hanger JB-2 and determined that there was no plan view to provide orientation of pall box dimensions. The inspector observed nine (9)
other travelers each of which included hanger plan views.
The licensee stated that a plan view is to be included for each hanger traveler.

k (2) The inspector observed that a clip dimension on hanger JS-5 was 35" x 25" x 5" x 8" instead of the required 3\\" x 2 " x
\\" x 6".
The licensee stated that this hanger would be reinspected.
Hanger velds exhibited no lack of fusion, cracking, porosity, overlap, or excessive undercut. There was no sign of rust on any of the welded joints. The inspector was unable to inspect all welds due to installation of fire proofing material at the hanger locations.
No items of noncompliance were identified.
b.
The RIII inspector observed sheet 3 of 4 of hanger Field. Change Request (FCR) 6196 installed on a rack of working drawings located in the Control Building. During the inspection of hanger E30-1004-01A-JS-F-2, sheet 3 of FCR 6196 was mistaken for S&L hanger location drawing E30-1004-01A-E1H, Revision D by licensee personnel. The inspector observed that the two drawings are identifical except for the drawing revision number and a handwritten notation to identify sheet 3 of FCR 6196. The inspector observed several other sheets
'
of various hanger FCRs on the same rack of working drawings. The licensee stated that appropriate corrective action would be imple-mented. This matter is unresolved.
(50-461/81-01-01)
c.
The RIII inspector questioned the licensee concerning the implementa-tion of S&L design changes to completed electrical raceway hangers.
Specifically, the inspector inquired as to procedures the licensee would follow to identify, prior to completion of turnover, all out-standing design changes to previous 1/ installed hangers. The licensee stated that this concern was undergoing review and that appropriate action would be implemented. This matter is unresolved.
(50-461/81-01-02)
d.
The RIII inspector observed installed electrical penetration IEE28E.
The Containment Building and Auxiliary Building ends were covered with a fireproof material which also provided a shield against dust and debris. -No damage was observed; the length of the flange bolts was as specified; the penetration was located per the location drawing; the pressure gage indicated proper pressurization.
e.
The RIII inspector observed the in process lasta11ation of electrical penetration IEE18E. The penetration was installed with care and precision in accordance with Conax Proc'edure No.
IPS-272, Revision A.
A Baldwin Associates inspector was present during the installation activities.
Areas inspected included the condition of the penetration after transport and uncrating, prelininary dimensional check and subsequent dimension adjustment, location, and orientation, allignment/ configuration, and cleanliness /
fitup.

Record Review of Electrical Work Activities a.
The RIII inspector reviewed Baldwin Associates Traveler JV-667 and Quality Control Support Fabrication / Installation Checklist JV-668 pertaining to the aforementioned conduit hangers. The records identified the inspector, welder, type of observation, results, acceptability, and identified related documents. The records were identifiable, retrievable, and appropriate for the activities inspected.
b.
The RIII inspector reviewed the qualification records of the visual weld inspector responsible for inspection of the previously mentioned hangers. The licensee indicated that the inspector cas qualified per ANSI 45.2.6 at the Level II position. The inspectors qualifica-tion records stated that the four years of previous inspection and test experience required by ANSI 45.2.6 were waived substituting 120 hours0.00139 days <br />0.0333 hours <br />1.984127e-4 weeks <br />4.566e-5 months <br /> of on the job training and 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> of self-study courses.
The inspector's qualifications were limited to fillet welds. The records included appropriated practical and visual examinations which the inspector passed.
c.
The RIII inspector reviewed the qualification records of the welders of the aforementioned conduit hangers. The records indicated proper qualification per AWS Dl.1.
.
d.
The RIII inspector reviewed the installation record for penetration IEE28E. The installation was properly documented on travelor 1EE28E, Revision 0 which was undergoing final review by Technical Services and Quality Control. The inspector observed NCR 3474 dated July 21, 1980, written during initial installation of electrical penetrations. The NCR stated that all of the 7/8" bolts received from Conax to be used to torque down the primary header plate to be attained. Disposition was to send the subject bolts back to Conax for rethreading. The licensee informed the inspector that the rethreading process was complete for all installed penetrations.
No items of noncompliance were identified.
