Diesel Generator 4160 Volt Cable Terminations The inspector examined the diesel generators (DG-X-1 A and DF-X-1B)
4160 volt cable teminations from the output of the generators to the bus connector located within the diesel generator teminal box.
The inspector found that the six 4160 volt cables from the DF-X-1 A generator unit had no cable temination lugs, while the six 4160 volt cables from the DF-X-1B generatur unit were terminated in 1/0 - 4/0 UIT (set screw-type cannector).
The inspector reviewed the Colt Industry drawing 11856085, Sheet 1, Revision 6 (B&R File #4300-0110) which specifies Burndy YA-34-2LN lugs for 500 MCM crimp type cable terminals.
The licensee recorded this deviation on Deviation Report 0764 datt.d May 25,1977.
The method of terminating the 4160 volt cables fre.n the diesel generators and mounting the cables onto the three i phase bus in the diesel generator teminal box was under review by engineering during this inspection period.
(
This matter is considered to be unresolved (320/77-20-01).

3.
Vendor Documentation For DH-3-LT-1 The inspector exmnined receiving inspection reports for the Borated Water Storage Tank Level Transmitter No. DH-3-LT-1 and observed that no vendor documentation had been required to be submitted.
This iten was identified on the instrument classification printout as Quality Class 4 and Seismic Class I (for mounting only). The Purchase Order requirements for documentation had not been estab-lished prior to completion of the inspection.
This item is considered to be unresolved (320/77-20-02).
4.
Responsibility for Storage and Cleanliness During Partial Turnover The inspector observed that the responsibility for storage and cleanliness during partial turnover had not been documented in procedures or instructions although in many cases parts of equip-ment had beca turned over to startup.
As exmnples, certain cables within cabinets were turned over to startup as part of a system while the remaining cables and the cabinet itself had not been turned over.
This item is considered to be unresolved (320/77-20-03).

5.
OC Records of Instrument Components The inspector examined the records shown below f'r conformance to the requirements of the applicable specification s and procedures.
a.
Receiving Inspection and Vendor Documentation Receiving inspection reports and required vendor documentation including performance tests, seismic qualification tests, equipment calibration reports, and certificates of conformance were examined for the following items:
(1)
