3.0 Licensee Actions on Previous Ins ection Findin s
(Closed) Construction Deficienc Re ort 84-00-19 Twelve reels of Rock-bestos class IE multi-,conductor cable with insulation damage were shipped to the licensee.
Of the twelve reels shipped to the Nine Nile Point Unit 2 site, eight reels were in storage and no cables were pulled from these reels.
All eight reels were returned to Rockbestos for replace-ment.
The return cable reels were documented on Returned Material Report Form No.84-116 The cables that were used from the four remaining reels were identified and re-pulled from the plant.
This task is identi-fied in N&D report No. A069.
The following inspection reports were used in the reinstallation and acceptance per NKD No.

E4078453 E4009181 E4077483 E5A40503 2FMSAGC003 2HVPBYC001 2RHSAGC043 The defective parts of the cables were removed from four (4)
reels remaining at the site and the rest of the cable reels were used in safety-related installations.
The Rockbestos Company letter of May 25, 1984 stated that in each case, the cable reels had received final electrical tests and were acceptable for use.
The test data to support Rock-bestos statement is on file in the licensee'
data system at this site.
This item is closed.
(Closed) Construction Deficienc Re ort 82-00-09 An audit by the licen-,
see s quality assurance organization of the General Electric (GE) documentation files could not produce data that demonstrated that the High Pressure Core Spray Diesel Generator complied with the requirements of IEEE 323-1971 and the environmental envelope for the Nine Mile Point, Unit 2 site.
A justification data package on this diesel generator is being prepared by the licensee in accordance with the criteria of IE Bulletin 79-01B and
CFR 50.49.
Supporting test data from the General Electric phase III test program and engineering analysis of similar type of data are presently being pr epared in support of their equipment qualification program.
The NRC is presently reviewing the licensee's test data and analysis as part of the near term operating licensee (NTOL)
program.

Ins ector Followu Item 83-18-12 - Cable 2RHSBY C027 not installed in conduit 2CC098YA as indicated in inspection report E3007337.
The personnel who performed the work disregarded the requirement that FgC must witness all category 1 cable pulls, which also
includes removal of cable from raceways, to facilitate instal-lation of other cables.
The original inspection report ( IR) No.
3007337 identified the cable as installed and IR No.
3008542 was generated for the removal of this cable without FQC presence.
Inspection of quality records indicate that this was an isolated case since no other areas were identified with this similar condition.
The electrical craft personnel were retrained using course No.
NMC-DI-EG0440.
Training records were reviewed to determine that electrical craft personnel requiring training did receive and complete the course.
This was verified by the inspector using computerized training record sort CTR SR 05B dated May 7, 1985 and discussions with electrical craft personnel.

Unresolved Item 83-18-01 8 83-18-02 Electrical raceway inspec-tions have been signed off as acceptable when the attribute for separation barriers has not been met (barriers have not been installed).
Specific attributes for separation barriers for raceway are not included in the inspection procedures.
The licensee's approach was to have quality control acceptance of raceways contingent upon the installation of approved bar-riers at a later date.
The NRC inspector observed that al-though barriers were shown on the design drawings, there were no procedures available for installation or inspection of these barriers.
Stone and Webster Engineering Company (SWEC) Field Quality Con-trol ( FQC)
has revised the quality control inspection plan N20E061AFA002 on January 15, 1984 to add an attribute for se-paration barriers'and to document an "L" (meaning later)
when the separation barriers are not installed.
The licensee's quality assurance organization verified on June 13, 1984 that the following events had occurred:
Inspection plan N20 E 061A FA002 was revised with the re-quired "L" attribute.
SWEC FQC has retrofitted the "L" status on those raceway tickets that had been previously accepted without the se-paration barrier inspection being performed, and Performed inspection of, raceways to assure that raceway tickets reflect the status of the installed field condition pertaining to separation barrier installation A computer program has been established which lists items that have been classified with an "L".
In addition to the
"L" listing, the attribute that the "L" represents is also listed as W06.
On a random basis the inspector selected
items from the April 12, 1985 computer run for verifica-tion.
The computer run and the selected items were veri-fied to be correct by the inspector during an inspection of the pull cards and cable locations at the site.
This item is considered closed.

Unresolved Item 81-13-05
CFR 50, Appendix A, Criterion 30 requires that means be provided for detecting reactor coolant leakage.
Regulatory Guide 1.45 provides the mini-mum acceptable method for detecting reactor coolant leak-age.
The Regulatory Guide states that one of two required methods shall be by Radiation Monitor of a sample.
No such provisions have been made in the licensee's design.
The licensee submitted their response to the Reactor Co-olant Pressure Boundary Leakage. Detection Systems concern in their Final Safety Analysis Report (FSAR) submitted for sections 5.2.5. 1, 5.2.5.9 and 11.5 in October, 1983 amend-ment 5.
Section 5.2.5.9 Regulatory Guide (RG) Compliance describes the licensee compliance with RG 1.45 position CI through C9.

Unresolved Items 83-18-13 83-18-14 83-18-84 83-18-73 83-18-90 and 83-18-93 Separation requirements relative to the Power Generation and Control Complex (PGCC) cable installations had not been properly inspected.
In addition inspection of some raceway installations, in the PGCC, relative to the requirements for physical separation had not been accomplished in accordance with the criteria established in the applicable procedures.
Specification E061A issued January 16, 1984, prescribed separation criteria including the use of dust covers and floor plates as qualified separation barriers in the PGCC and permits cable installation and acceptance as an in-dependent program from barrier installation and acceptance.
An additional specification change to E061A was issued to provide a criteria for a formal program for the instal-lation and acceptance of barriers.
General Electric (GE) and Stone and Webster Engineering Corporation (SWEC) personnel performed an inspection of the category 1 divisional panel and termination cabinets.
Wire
identification, tagging and inspection for subdivisional separation has been completed with areas that are to be corrected, identified.
The inspector randomly selected 15 separation problems.
In each case the engineering disposition was completed, but only 10 of the selected 15 items have been corrected.
The other 5 are scheduled to be completed within the next months This item is closed.
4.0 Cable Pull Tension Calculation Limitations The Stone and Webster Engineering Corporation (SWEC) program for establishing cable pulling limitations are identified in calculation programs Nos.
EC-112 titled "EC-0 Cable Pulling Tensions" and EC-101
"Bundle Cable Pulling."
The values for maximum pull tension (lbs.) listed in appendix J of the cable pulling specifications are derived from the Tensile Strength and Maximum Sidewall Tension values listed in EC-0 calculation sheets (EC-112).
The numbers are derived from using the following base calculations.
Maximum Pull Tension Limitation as a function of conductor tensile strength for copper conductors.
T max =
where T max =
N CMA
.008 xN x CMA maximum tension in pounds number of conductors in cable circular mi 1. area of one conductor Maximum Pull Tension Limitations As a Function of Sidewall Pressure The maximum sidewall pressure values varies with the cable manufac-turer, however, the data used in establishing the appendix J cable values for maximum pull tension ( lbs.) were derived for this site from Okonite, Kerite and Rockbestos data.
SWEC has assigned
"Mark Numbers" for various cable configurations.
The pull tension (lbs.) is then calculated for each
"Mark Number" configuration using the maximum pull tension formula and the maximum pull tension limitation values.
The lowest number derived from the two methods is used as the cable "Mark Number" maximum pull tension value.
Using the SWEC calculation methods for calculating maximum cable pull tension values for the various
"Mark Numbers",
the inspector selected 10 "Mark Numbers" for verification.
The inspector verified by cal-culation that the selected
"Mark Numbers" were the lowest values of the two referenced calculation methods'
