Functional or Program Areas Inspected 1.
Observation of Electrical Installation Activities a.
The Region III inspectors selected four Division One Class IE electrical cables which had been installed in Unit 1.
The routing of each cable was compared with the routing require-ments identified on the respective pull cards. The inspectors observed the following:
(1)
125 volt, DC power cable 1DC001 was observed to be routed correctly from 125V DC ESF Distribution Center IDC05E to 125V DC Battery 111, Rack 2.
(2)
125 volt DC power cable 1DC002 was observed to be ~ routed correctly from 125V DC Battery 111, Rack 2 to 125V DC Battery 111, Rack 1.
(3)
125 volt DC power cable IDC003 was observed to be routed correctly from 125V DC ESF Distribution Center 10C05E to 125V DC Battery 111 Rack 1.
(4) 600 volt' control cable IDC067 was observed to be routed correctly from 125V DC ESF Distribution Center IDC05E to routing point 1R477. At this point the cable was coiled pending installation of raceway bridge-12?14C. The Region III inspectors observed that in some instances routing points were identified with temporary markers.
The licensee was documenting the use of these temporary markers on Inspection Correction Reports.

The Region III inspectors observed that the raceway internals were free of hazardous debris and sharp edges. Conduit bushings were installed as required. The cables and raceways were properly identified and undamaged. No separation problems were identified, b.
The Region III inspectors observed the installation of a Class IE
cable identified as 1AP045 between 4160 volt ESF Switchgear IAP06ES and Main Control Board Panel IPM01J and determined the following:
(1) The size and type of cable pulled was as specifi. on the cable pull sheet.
(2) The raceway was clean and undamaged.
(3) Contractor QC inspections had been made to ascertain loca-tions where the cable might be subjected to abrasion or unusual strain. The Region III inspectors observed that workmen were stationed at sufficient intervals to guard against damage to the cable.
(4) Temporary raceway markers, where installed, were documented on an Inspection Correction Report.
(5) The cable was being routed as designated on the cable pull sheet.
c.
The Region III inspectors observed the follo, ing raceway instal-lation drawings located in the Reactor Containment and Auxiliary Buildings:
(1) 20E-0-3062H, Revision J (2) 20E-1-3252A, Revision F (3) 20E-1-3252H, Revision C (4) 20E-1-3283, Revision G (5) 20E-1-3285, Revision F (6) 20E-1-3252, Revision B The Region III inspectors verified that the above drawings were of the current revision.
2.
Review of QA Implementing Procedures The Region III inspectors reviewed L. K. Comstock procedures relative to raceway installation, cable installation, cable termination, and cable protection and housekeeping. During this review, the inspectors identified areas of concern relative to the following procedure:

L. K. Comstock Procedure 4.3.9, dated May 28,1981, " Cable Termination Installation."
a.
The procedure does not address electrical cable separation re-quirements to be observed during the " training in" of cables into equipment during terminatica.
The licensee stated that while field personnel have been instructed not to bundle Class IE and Non-class 1E cables, the separation distance to
be maintained between redundant cables and between Class IE
,
"
sud Non-class IE cables is still being developed.
b.
The procedure does not address the subject of torquing require-ments for cable terminations.
These items are considered open.
