have be changed to require QCI changes to be reviewed by the licensee before issue.
This item is considered closed.
(Closed) Violation 81-06-03 pertaining to solenoid valves not identified with hold tags in accordance with procedural requirements. The inspec-tors reviewed nonconformance report no. 7834 and the associated corre-spondence which documents the deficiency and disposition. Documentation indicated that hold tags had been placed on all the non-conforming solenoid valves. At the time of the inspection the solenoid valves were in place and had been reinspected. The inspectors verified that the solenoid valves were reinstalled.

This item is considered closed.
(Closed) Violation (81-07-01) pertaining to installed damper control assembly for HDM-17508A&B not conforming to certified drawings of the procured system. The licensee also noted four additional deviations from the drawings during the investigations of this problem. As a result, sn inspection was performed on all control dampers ordered from American Warming and Ventilation Co., which were installed in Unit #2.
The inspectors verified that the changes have been corrected and instal-lation modification were inspected.
This item is considered closed.
(Closed) Unresolved Item (388/81-07-02) pertaining to the mounting plate for the Damper control assembly.
The inspectors reviewed Design Change Package 532 which implemented reinforcement of solenoid valve mounts for the pneumatically operated dampers to meet seismic qualification require-ments. The modifications were verified to be accurate by seismic quali-fication tests documented on vendor prints 8856-M396-3-1 and 8856-M396-S-1. The inspections, results, and corrective actions taken were documented in the disposition of NCR 7834.
The inspectors reviewed the disposition of NCR 7834 and found it to be acceptable.
This item is considered closed.

a.
The inspectors reviewed the following applicable documentation and procedures used by construction personnel:
--
Field Procedure (FP)-E-1, Revision 5, " Procedure for Handling and Storage of Electrical Cable"
--
Field Procedure (FP)-E-Z, Revision 7, " Procedure for Installa-tion and Computer Documentation of Electrical Raceways'!
--
Field Procedure (FP)-E-4, Revision 6, " Procedure for Installa-tion of Permanent Plant Electrical Equipment"
--
Field Procedure (FP)-E-5, Revision 6, " Procedure for Cable Card Control and Installation of Electrical Cables" Field Procedure (FP) E-8, Revision 2, " Procedure for Cable

Electrical Cables" The above documents were updated as required by the program documen-tation and signed by the responsible personnel.
No violatioas were identified.
b.
The inspectors witnessed a cable pull for cable Bk2V14515 from 2C 236A to 20624. On review of the applicable cable pull card, it was noted that the scheduled length for the cable was 103', but the actual length recorded on the card was 300'.
The QC Inspector and General foreman were questioned about the large discrepancy between the cable lengths. They stated that the raceway length was actually measured, but it is not recorded. The Electrical Superintendent determine * t v cable length to cut using pull card length and a safety Dutm D;e cable cut from the reel is recorded on the pull card e etb personnel also stated once the cable is terminated, the y aec A is returned to the shop and the amount is subtract-ed fd m the ce#1e length on the pull card. The cable length on the pull card is used to document the actual cable length. The pull card data is entered into the computer program and is the data that produces the information in the Circuit Schedule Control Document.
The inspectors determined that the licensee has not defined what is excessive cable length and the numbers stated by the licensee varied from 5 feet to 30 feet to 10% of the cable pulled length. Neither the cable installation procedure FP-E-5 Revision 6 nor the termina-tion procedure FP-E-8 addre-'es the subject of up-dating the pull

card cable lengths with the field cable cut length data.
To verify this condition the inspectors reviewed the following cable pull cards:
Circuit Cable No.
Scheduled Length Actual Length CF200803A 252'
265'
CF2Q3002A 142'
180'
PF2V2600A 233'

275'
PP2S1201A 491'
555'
RK2Q7002Q 395'
560'
The inspectors determined that the " Circuit Actual Length" value on the pull card was the "as cut" length and not the "as terminated" length. A review of the Electrical Circuit Schedule data verified that the data is the "as cut" length of cable and not the "as terminated" length.
The "as built" design of the safety related cable system appears to have cable length data that is on an average of 40% over the installed figure. This was also identified by the licensee in their Performance Evaluation Summary report objective number CC-4.
This item is unresolved pending NRC review of licensee's evaluation and resolution.

Electrical Cables and Terminations - Quality Records The inspectors reviewed quality related records relative to electric cables, terminations and related equipment to ascertain whether these records reflect work accomplishment consistent with NRC requirements and licensee commitments.
a.
The inspectors reviewed the records of two licensee formal Quality Assurance audits and ten informal audits associated with cable installation, raceway installation, and cable termination to ascer-tain whether the records confirmed that the required audits were performed and that the deficiencies identified were corrected and documented.
No violations were identified.
b.
The inspectors reviewed ten licensee nonconformance reports relative to cables, terminations and related equipment to ascertain whether the records are current, complete, reviewed ad reflect that appro-priate corrective action was taken.
No violations were identified.
c.
The inspectors reviewed five cable tension calculation worksheets to ensure that cable pull procedures were being followed, calculations were completed in accordance with the licensee guidelines and that pulling (tension) limits were not exceeded.
No violations were identified.
d.
The inspectors reviewed thirteen safety-related cable termination Cards including the associated quality control inspection records and megger test data sheets. Minor discrepancies were identified by the inspector which were corrected by the licensee before the inspectors left the site.
It appeared that the discrepancies were due to carelessness in recording dates and data.
No violations were identified.
e.
The inspectors reviewed nine safety-related cable pull cards includ-ing the associated quality control inspection record.
The following discrepancy was noted:
Cable PPZSIZ01A indicated that the cable was machine pulled and
--
that a dynamometer was used, but the maximum tension allowed block was signed as "N/A" (not applicable), and no maximum tension was stated on the QCIR as required by procedure.
The discrepancy was immediately brought to the attention of the licensee. The licensee supplied the inspector the appropriate cable
O V
pull tension calculation worksheet and verified that the maximum tension was not exceeded. A memo to file was entered by the licensee to correct the pull card.
No violations were identified.
.4 7.
power, Voltage and Relay Study The licensee is preparing a power, voltage and relay study for the present design of the Unit 2 electrical systems. The inspectors informed the licensee that due to the wide tolerance on cable pull length, refer-ence paragraph 4, the calculation used in the power and voltage calcu-lations could have errors on an average of over 40%.
This item is unresolved pending NRC review of licensee's evaluation and resolution.

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items or violations.
Unresolved items identified during this inspection are discussed in Details, paragraphs 4 and 7.
