Electrical Components and Systems
.
a.
Review of Procedures
,
The IE inspector reviewed the following Fischbach ano Moore procedures to determine if appropriate and adequate measures have been established to provide the necessary details required for cable terminations and splices and dielectric measurements of insulation systems for cable and
'
equipment.
CP-307, Rev. 3, 1/8/79, " Cable Terminations and Splices."
CP-401, Rev. O, 1/12/79, "Hy-Pot Testing of Cable and Equipment."
CP-405, Rev, 4, 10/8/79, " Insulation Testing of Cable and Equipment."
No discrepancies with the requirements of 10CFR 50, Appendix B, IEEE Std 384-1974 or IEEE Std. 62 were noted.
b.
Observation or Work The IE inspector selected two 4160 Vac and two 125 Vdc cables that had previously been installed to determine if the installation had been accomplished in accordance with established design drawing, procedures and other documents.

In addition to the above, the IE inspector noted a hold tag and conditional release on the following 480 Vac MCC module.
480 Vac MOV Control Flow Control Valve 3AC-TMG46A MCC-3A313S F & M Hold Tag CR-8041 Conditional Release E-93 Inspection h port 317-28-02 No items of noncompliance or deviations were ident'fied.
c.
Review of Records The IE Inspector reviewed the records for the cables and MOV controls identified in item b above.
The record review did not identify any areas where the QA program and procedures were not being adequately implemented.
,
No items of noncompliance or deviations were identified.
5.
Reactor Control Element Drive Mechanism The IE inspector observed NISCO welding an upper canopy seal, Weld Number 35 on Drawing 3015-022, for the Control Element Drive Mechanism.
Seal welding was being accomplished with the automatic gas tungsten-are welding process using certified weld wire type ER NICRFE-5 (Heat No. H-66-75-07069A)
and qualified welders (1003, 1029 and 1037) as specified in weld procedure specification NPS 43.5.2.
The material text report and welder qualification reco-ds were reviewed and found to be consistent with the requirements in Section III of ASME B&PV Code.
No items of noncompliance or deviations were identified.
6.
Reactor Coolant and Other Safety-Related Piping a.
Review of Procedures The IE inspector selectively reviewed Tompkins - Beckwith welding procedures and supporting procedure qualification reports for welding reactor coolant and other safety-related piping for compliance with the ASME B&PV Code, Sections III and IX, 1974 Edition through summer 1976 Addenda. The documents reviewed included:

Observation of Work The IE inspector observed the Tompkins - Beckwith activities at various stages of weld joint completion.
The traveler (Q2+5 MS-1C-10 F/E) for Main Steam field weld FW-1 was reviewed for adequacy of welding preheat and postweld heat treatment specified for a weld thickness of 1.250 to 2.062 inches.
The requirements were consistent with the qualified welding procedure and section NC of the ASME B&PV Code. Welding of Safety Injection Piping was observed being performed on two field welds designated FW-1 on travelers Q1-SI-IC-20 E and Q2-SI-IC-102 F/E.
The welding material and qualification of welders were consistent with requirements of WPS 8.2.
Three welds in the component cooling piping, designated SW-18 on Traveler Q3-CC-LW3-CC-17 F/E and FW-1 on Travelers Q3-CC-1C-972 E and Q3-CC-1C-973 E, were observed and the welding materials traced to the certified material test reports.
Welding materials were consistent with requirements of WPS 1.8 for SW-18 and WPS 1.7 for FW-1.
The weld reinforcement on two feedwater pipe welds, FW-2 and FW-3 of Traveler Q3-FW-1C-862 F/E was inspected and found consistent with visual inspection Procedure TBP-26 requirements.
The in process testing of three welders was observed by the IE inspector. The welders were using the electrode, pipe material, welding process and welding position specified on the welder per-formance test record.
The three welder performance tests specified radiographic inspection for final acceptance but were unavailable for evaluation at the time of the inspection.
In the areas inspected, no discrepancies with the requirements of ASME B&PV Code Section IX were noted.
No items of noncompliance or deviations were identified.
