During this inspection, the Region III inspcctor performed a general inspection of the Auxiliary Building and the Unit 2 Containment. This inspection consisted of reviewing cable tray and conduit for separation, support, proper bolting practices, and proper training of cables within the cable tray. Approx-imately 2,000 feet of cable tray and 800 feet of conduit were inspected. During this general inspection, non-safety-related cable 2AS-132-C2B was observed in safety-related riser (vertical run cable tray) 2R257-C2E and non-safety-related cables 2AS-127-C2B, 2AS-128-C2B, and 2AS-129-C2B were observed in safety-related riser 2R253-C2E.

Further investigation revealed that these four cables are associated with the " Steam Generator Blowdown Isolation Valves" and are classified as

" Quasi-Safety-Related Cables."

Quasi-Safety-Related Cables are cables which are part of a Class 1E circuit (serve a safety-related function) and have a portion of their routing in a Category II structure (Turbine Building). For that portion of the cables routed in the Turbine Building, the cables are routed in conduits dedicated to Quasi-Safety-Related cables. When these cables enter the Auxiliary Building, they are routed in safety-related raceway of the same division. Quasi-Safety-Related cables are associated with:

(1) Turbine Stop Valves; (2) Turbine Pressure Switches; (3) Feedwater Regulating and Bypass Regulating Valves; (4) Turbine Impulse Pressure; (5) Condenser Steam Dump Valves; and (6) Steam Generator Blowdown Isolation Valves.

No violations or deviations were identified during the inspection of MCCs 231X5 and MCC 232X5 or during the general inspection of Unit 2 Containment and the Auxiliary Building.

4.

Review of Electrical Records a.

During this inspection, the Region III inspector reviewed the Material Receiving / Inspection Reports (MRR), vendor documentation packages, and installation documentation for MCCs 231X5 and 232X5.

(1) MCC 231X5 was received from Westinghouse on MRR 7691, dated October 8, 1979.

Interim acceptance was given on November 2, 1979 (quality documents accepted) and final acceptance was given on August 18, 1980 (engineering documents accepted).

S&L's documentation acceptance letter was on file.

HECo installation records included: Weld Record Cards 11470, dated May 27, 1982 and 41414, dated December 13, 1982; weld inspection reports dated June 16, 1982 and December 14, 1982; QC inspection checklist dated Decemhr 8,1982. DR1798 documented that one of the panel coors was sprung. The door

was repaired and DR1798 and the open inspection report was closed on September 2, 1983. Documentation for this MCC was found acceptable by the inspector.

(2) MCC 232X5 was received from Westinghouse on MRR 7870, dated November 15, 1979.

Interim acceptance was given on December 6, 1979 with final acceptance on July 23, 1980. S&L's documentation acceptance letter was on file.

HECo installation records included: Weld Record Card 11474, dated June 3, 1982; weld inspection report dated June 15, 1982; QC inspection checklist dated December 8, 1982. DR1825 was prepared to document missing bolts.

The bolts were replaced and DR1825 and the open inspection report was closed on July 28, 1983. Documentation for this MCC was found acceptable by the inspector, b.

During this inspection the inspector reviewed the trend analysis of electrical work activities. A trend analysis is performed quarterly by HECo and annually by Pittsburgh Testing Laboratory (PTL) for the licensee. The inspector reviewed the HECo third quarter trend and the PTL annual trend report dated May 22, 1985. No adverse trends were identified in the electrical area.

No violations or deviations were identified in the area of electrical records.

Review of I&C Work Activities and Records

,

a.

During this inspection, the Region III inspector selected six safety-related instruments for review. This review ' entailed the verification of sensing line size, slope, support and that the high and low sensing lines are properly tenninated at the instrument and process line.

In that the traveler package was used for the walkdown, the installation. records were reviewed in conjunction with the walkdown. Except as noted, the installations and records were found acceptable.

Following are the details of this review:

-

(1) Instrument - 2FT-CS016, located on instrument rack 2PL81JB.

This panel is located in the Auxiliary Building, 346' elevation, column V/21. Drawing T549-2FT-CS016, Revision 5,.was used to perform the walkdown. The following records,were'a part of the traveler package: FCR No. F-36383, dated October 16, 1985.

Revised instrument mounting details; hanger calculation sheet; hanger travelers; flexible hose date sheets; weld traveler; bill of material; instrument attachment record that verifies:

instrument identification, fastner size, torque verification, mounting details and proper termination of the high and low.

pressure sensing lines; pipe bend inspection record; and NCR 361, dated October 22, 1985. This NCR was prepared to document that the vendor tubing on 2PL81JB was modified without engineering (S&L) approval. As of December 12, 1985, NCR 361 is still open and the final walkdown of this instrument system has not been completed.

(2)

Instrument - 2FIS-611, located on instrument rack 2PL81JB.

Drawings T548-2FIS-611, sheet 1, Revision 5 and sheet 2, Revision 3, were used to perform the walkdown. The following records were a part of the traveler package: FCR No. F-35830, dated May 21, 1985, added instrument mounting plates; FCR No. F-36408, dated October 16, 1985, provide a hanger modification; bill of material; hanger calculation sheet; flexible hose data sheet; weld traveler; pipe bend inspection record; final walkdown record; open NCR 361; and field work request (FWR) 5188, dated November 22, 1985, was issued to rework sensing line welds per the disposition on NCR 361.

This panel is located in the Auxiliary Building, 364' elevation at column M/24. Drawings T447-2FT-AF013, sheet 1, Revision 4

-

and sheet 2, Revision 5, were used tp perfonn the walkdown.

The following records were part of the traveler package:

FCR No. F-36242, dated September 20, 1985, revised the instrument mounting details; weld traveler; bill of material; instrument

,

attachment record; pipe bend inspection record; and final walkdown inspection record.

.

Revision 5 were used to perforra the walkdown. The following records were part of the traveler package:

FCR No. F-36242; instrument attachment record; weld traveler; bill of material; pipe bend inspection record; and final walkdown inspection record. During the walkdcwn of this system, it was observed that four hanger clips had not been installed. This deficiency was corrected on FRR 5254 prior to the inspector leaving the site on December 13, 1985.

(6) Instrument 2FIS-610, located on instrument rack 2PL81JA. This parel is located in tne Auxiliary Building, 346' elevation at column W/19. Drawings T541-2FIS-610, sheet 1, Revision 10, sheet 2, Revision 5, and sheet 3, Revision 2, were used to perform the walkdown. The following records were part of the traveler package: pipe bend inspection record; open NCR 360; FWR 5189, dated November 22, 1985, was issued to rework the sensing line welds per the disposition on NCR 360; FCR No. F-36387, dated October 18, 1985, was issued to revise the sensing line hangers on 2PL81dA; instrument rack installation traveler; FCR No. F-35830; hanger calculation sheets; hanger travelers; weld records; instrument attachment record; bill of matericl; and the flexible hose data sheets. Two instances of reverse sensing line slope had been documented on Fabrication /

Installation Surveillance Report (FIS) dated October 8,1985.

FWR 5123, dated November 4, 1985, was issued to correct the reverse deficiencies identified on the ISR.

(7) During the walkdown of the containment spray (CS) sensing lines, it was observed that one U-bolt or hanger 2FT-CS012-H127-3 was not double-nutted in accordance with the drawings and specifications. A research of the records indicated that PAP had previously identified this deficiency during their final walkdown on October 21, 1985, and appropriate action was being taken to have the deficiency corrected.

.J b.

During a general tour of, Unit 2 Containment and the Auxiliary J

o Building, the following observations were made:

,

,

'

(1)- The cable trough hanger was damaged on instrument rack 2PL50J.

. /

This. instrument rack is located in Unit 2 Containment, 377'

elevation, azimuth R342*.

PAP prepared FIS 3060 to document the observed damage. This report is forwarded to CECO'for corrective action by HECo.

(2) At instrument rack-2PL84JB, observed the set-up and hydrostatic

'

test of: sensing lines associated with instrument 2FT-AF016
