Status of Previously Identified Items (Closed) Unresolved Items 82-04-01, 82-04-02, and Violation 81-13-02 pertaining to conflicting cable tray separation requirements between the PSAR and the Cable Tray Installation Specification. Electrical Engineer-ing Specification E-061A has been changed to comply'with the separation requirements identified in RG 1.75.
The inspection plans for raceway inspections has been revised to comply with the requirements of electrical specification E-061A.
The revision to both the engineering and quality inspection procedures includes the fire barrier and material concerns of the above referenced inspection reports unresolved items.
This item is closed.
(Closed) 50.55(e) report on the ITT Barton Pressure Transducers /Trans-mitters Part No. 04R-29098, 4-20 ma.
On December 14, 1982, the licensee verified that the ITT Barton Pressure Transducers (Part No. D4R-29098, 7
4-20 ma) will not withstand the test parameter for radiation of 1 x 10
3 Rads. The corrective action and analysis of the safety implication for Nine Mile Point Unit 2 will be submitted to the NRC by February 1983.
The NRC Senior Resident Inspector will follow the licensee's action on this item and follow-up reports will be part of his monthly report.
This item is closed and will be followed by the NRC Resident.
(Closed) Unresolved Item 82-04-03 pertaining to storage of electrical equipment in storage and stored in place. During the plant tour,_the inspector observed that the stored-in place electrical equipment was protected from dirt and dust with heat applied to the equipment.
The housekeeping program for maintenance of safety-related equipment was reviewed by the licensee with noted improvement in all areas. The work areas were being cleaned, as stated in their procedures.
This item is closed.
3.
Facility Tour Work in progress, completed work, and plant status were observed during a general inspection of the electrical construction activities.
Electrical.
installation activities were examined for obvious defects or violations with NRC requirements or licensee committments. Craft and supervisory personnel encountered in work areas were interviewed.
No violations were identified.
4.
Raceway Installations NRC Inspection Report 410/82-11 discussed the use of Kellem metal or Raychem rubber-like grips to be used on C, K, and X cables in the vertical tray systems at this site.
The licensee has not issued installation schedules for this design; and, as of this inspection period, minimum installatin work has been performed on the Kellem grip designs identified in E and DCR No. 1341.
The Kellem grip installation will be part of an NRC inspection of the safety-related raceway system to be performed during that phase of the construction cycle.
No violations were identified.
5.
Documentation of As-Built /As-Installed Design The licensee issued Project Guideline No. 22 September 15, 1982, which defines the "as-built" or "as-installed" design criteria for the Nine Mile Point Nuclear Station Unit 2 facility.
The licensee has defined "as-built" and "as-installed" as follows.
4 A.
As-Built "As-built production drawing are those which reflect or have been updated to reflect the actual installation within the specific tolerance and appropriate to the drawing scale."
8.
As-Installed "As-installed production drawing are those which have the design dimensions verified and revised to reflect the actual installed location dimensions. The requirements for such measurements and limits of accuracy are specified in the affected vendor / contractor specification."
A review of the cable installation does not fall into either the "as-built /as-installed" definition.
(See paragraph 6 of this report).
It also appears that the documentation system does not stamp specifications, drawings, diagrams, and computer lists with the "as-installed" identifica-tion.
The licensee was requested to review the Project Guideline Proce-dure No. 22 with respect to the requirements of 10 CFR 50, 50.2(3)(u) and Appendix B III Design Control.
This item is unresolved, pending NRC review of the licensee actions.
(50-410/82-16-01).
6.
As Installed Computer Runs of Safety-Related Cable Installations The computer lists for safety-related cable installations identity the cut cable lengths only and do not list the "as-installed" cable lengths as identified in the Project Guideline No. 22 definition for as-installed equipment.
In a random inspection of cable pull cards, the licensee identified the pull card estimated length to the installed cut length to have a differ--
ence of 30% to 40% on the high side. The computer lists identifies the 30% to 40% value as the "as-built" design value.
It this value is used for the power study analysis, then the "as-built ;es*gn information does not comply with the requirements identified in 10 CFi. 50, 50.2(3)(u).
i The electrical discipline was only one area where the problem of "as-built vs. as-installed" criteria was identified by the inspector. The licensee is to look at all design areas to assure that their site design will provide "as-built /as-installed specifications, drawings, diagrams, and computer lists, as a minimum, to meet the requirements of'10 CFR 50, 50.2(3)(u).
This item is unresolved, pending NRC review of the licensee's actions.
(50-410/82-16-02).

Documentation Review The inspector reviewed the licensee's documentation to assure that the changes identified in the June 25, 1982, letter to the NRC from the licensee, dealing with the separation and fire barriers designs, had been implemented. The inspector reviewed the following documentation.
NMP2-S204P - Cable Tray Support, NMP2 - E061A - Electrical Installation Specification, and Quality Assurance Department Inspection Procedures.
The licensee has released engineering which has been incorporated into both the engineering and the inspection procedures listed above. The inspection verification activity is being performed by the licensee.
No violations were identified.
8.
Relay Coordination Study The power and relaying studies for this licensee are part of a report that is submitted under separate cover to the NRC. This item is being closed by this inspection report and will be reviewed and documented later by the NRC.
9.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain if they are violations or deviations. Unresolved itens are discussed in paragraphs 5 and 6.
10.
Exit Meeting The inspector met with licensee and Architect-Engineer / Constructor repres-entatives (see paragraph 1) at the end of the inspection on December 16, 1982.
The inspector summarized the purpose and scope of the inspection and identified the inspection findings.
