Licensee Identified Items (0 pen) Item 369/79-28-03, Barton Transmitter Environmental Qualification Testing. The licensee has returned the seven Barton Lot I differential
.
-2-pressure transmitters to the manufacture (Barton) for the additional testing.
The expected date for return of the transmitters at the McGuire site is December 1, 1979.

Independent Inspection An inspection was made f Safety Injection (SI) Pump 2B and its associated safety-related components within the pump room of Unit 2.
During this inspection it was noted that nonsafety-related black cable number 2N717 was routed with three yellow color coded safety-related power cables to the motor operator for SI valve number 2NI136B. Af ter exit f rom the yellow color coded safety-related cable tray, the non-safety-related black cable entered a junction box which contained red color coded safety-related cable number 2*NI958. Within the junction box, the outer cable jacket was removed from both cable number 2NI717 and 2*NI958, and their conductors routed to the limit switches for SI valve number 2NI136B. The inspector questioned whether the non-safety-related black cable (number 2NI7I7) violated the safety-related cable separation criteria which requires no non-safety-related cables be mutually common to redundant safety-related cables. The licensee agreed to investigate this concern and provide additional informa-tion. This item is identified as Unresolved item 370/79-22-02, Safety-related cable separation at Safety Injection valve number 2NI136B.
.
The inspector was informed that for Unit I the corresponding non-safety-related black cable was routed with the red color coded cables connected to the valve's limit swiches.

Electrical (Components and Systems I) - Observation c; Work and Work Activities - Unit 2 The inspector selected the Class IE 4160-volt bus 2 ETA, the preferred power and the emergency diesel generator feeder breakers to this bus, the supply breakers associated with the Class 1E 480-volt switchgear and the supply breakers for the 4160-volt motors of this bus for examination.
For the above listed equipment, the inspector examined documentation for; receipt inspection, identification, installation and inspection, calibration and trip setting data. The location, separation, and the protection and cleanliness preservation of the equipment were observed.
Within the areas examined, no items of noncompliance were identified.
8.
Electrical (Components and Systems I) - Review of Quality Records - Unit 2 The inspector reviewed the quality records for the components identified paragraph 7 above. The records review was in the areas of equipment receipt inspection, material certification, and installation procedures and inspec-tions. The equipment receipt inspections were documented in accordance with Quality Assurance Program (QAP) Procedure P-1, " Receiving Inspection".
Material Certification was documented by the vendors in accordance with the Quality Assurance Manual (QAM). The equipment installation and inspection 1937 112

The "Special Surveillance" audit report number SS-125 was reviewed. This audit was of the site transmission department conducted on September 26, 1979 by the site QA department.
Within the areas examined, no items of noncompliance were identified.
9.
Electrical (Cables and Terminations I) - Observation of Work and Work Activities - Unit 2 The inspector selected the five safety-related power cables as listed below for physcial examination.
Cable No.
Description 2*EPE537 4160-volt power feeder cable 2*ND550 4160-volt power feeder cable 2*EPC621 4160-volt power feeder cable 2*EPC623 4160-volt power feeder cable
.2*EPE502 600-volt power feeder cable Work and work records for storage and handling, indentification and control of issue, identification of nonconforming material and QC inspection proce-dates were reviewed.
The cable routing, protection, separation, type and identification were examined.
These cables were pulled, documented, and QC inspected using QAP Procedures M-40, " Electrical Cable Installation and Inspection" and M-41,
" Electrical Equipment Installation Inspection.
During the examination of safet y-related cables 2*EPC62: Ind 2*EPC623, it was determined that the " Cable Installation Data Cards" did not list the correct " exit" cable tray junction points. These two cables were routed via the same cable trays and had the " exit" cable tray junction point listed as 14802 located in the penetration room.
The actual " exit" cable tray junction point is 14800 located just inside the Diesel Generator number 2A room. The cable routing installation inspec-tions had been completed and were verified satisfactory by a QC inspector's signature on the " Cable Installation Data Card".
Supplemental Inspection Instructions (Form M-41B), serial number 014, implemented by QAP Procedure M-41 for caMe routing inspections, requires the QC inspector to verify that cables are correctly located by cable tray junction points and the
" Cable Installation Data Card" list the " exit" cable tray junction points for safety-related cable. This item is a deficiency and is identified as 370/79-22-01, Failure to follow QAP Procedure M-41B, serial number 014,
" Cable Routing Installation Inspection".
