Licensee Action on Previous Inspection Findings

-

Closed - Unresolved item numbered 413/414/80-07-02, Coating Applicator Quali-fications. It could not be determined how Duke assures that coatings personnel are qualified to apply the various coatings materials. A construction procedure, CP-455, has been written to assure that site coatings personnel are adequately trained and qualified.

4.

Unresolved Items Unresolved items were not identified during this inspection.

5.

Material Receipt, Handling and Storage - Units 1 & 2 The inspector observed the receipt, handling and storage of materials; the following observations were made:

,

a.

Receipt inspection; materials received from Tube Turns Manufacturing Company purchase order numbered F226 release 917. The material was received, inspected and documented in accordance with DPC procedure P-1.

b.

Storage of materials which have not been released for construction installation:

(1) The inspector toured all of the outside storage areas which contained safety-related materials that have not been released for installation.

(2) The inspector toured all of the site warehouse storage areas.

(3) During the various tours the inspector observed; materials being properly stored on supports, materials being covered and segregated as required, identification of not. conforming materials, and identification attached to materials to assure traceability.

c.

Storage of safety-related equipment that has been released for instal-lation:

(1) Observed the stored condition of: safety injection pumps 1A, IB, 2A, 2B; Units 1 and 2 positive displacement pumps and centrifugal charging pumps numbered 1A,1B, 2A, and 2B.

(2) With the exception of safety injecticn pump 1A and unit 1 positive displacecaent pump the stored conditions of the above pumps were found to be as required by their applicable storage inspection P-3A forms. The former pump was found to have cable, scrap iron and debris on top of the pump and its motor. The latter pump had trash, iron and debris on it and its' motor.

The inspector brought these unsatisfactory conditions to the attention of the respocsible DPC QC inspector who had them corrected (reference DPC corrutive action notices numbered M-455 and M-456).

d.

During the varicus tours associated with the above observations the inspector observed the riggine and handling of several safety related pipe spool pieces (both staialess steel and carbon steel), several safety-related valves and plate steel. Their were no instances whereby unsatisfacotry rigging practices were observed.

Housekeeping of auxiliary building and reactor buildings:

e.

(1) During tours the inspector observed that in general safety-related piping and mechanical equipment were not being subjected to unsatisfactory housekeeping conditions other than two pieces of ASME Class B stainless steel which were found laying in water at elevation 543', column 56 MM of the auxiliary building.

The inspector brought this unsatisfactory condition to the attention

.

of the responsible QC representative who required that this condition be corrected.

DPC corrective action notice numbered M-467 was prepared.

(2) During these tours the inspector observed that in general the in place installed condition of Class IE is not unacceptable; however, there were several unsatisfactory housekeeping conditions related to Class IE cable tray and cable. The inspector observed and was informed by DPC QC personnel that there has never been a planned-systematic inspection to verify the adequacy of housekeeping in work areas for Class IE equipment. The following are some of the types of unsatisfactory housekeeping conditions which were observed:

(a) In the auxiliary building at elevation 543' at column 55 (FF); a temporary electrical cable and an unused 10' board laying inside a class IE cable tray which contained Class IE cable and scaffolding laying on top of a installed 10-inch wide " electro plate" Class IE cable tray at column 52-53 GG-HH.

(b)

In the auxiliary builidng at elevation 577' two Class IE installed cables laying on the floor in an area which has previously contained some standing water columns 50-51 JJ and 52 HH also at column 53-54 KH a 4' piece of unused board was laying inside an installed Class IE cable tray.

(c) The tops of several Class IE panels located outside and around unit I battery rooms had their tops damaged. Their tops appear to have been damaged by workers who used them as supports while conducting other work activities above the panels. Panels involved are IECD, 1EID, 1ECC, IECC, IEIC, 1ECA and IEIA.

(d) In the auxiliary building at elevation 560' south corner a piece of support steel approximately 4' long was laying on top of Class IE cables which were in a Class IE cable tray.

The inspector observed that a worker was setting on top of the piece of support steel.

(e)

In Unit I reactor building inside the containment at elevation

'57' at approximately 156 degrees two pipes 3' diameter and 2' in length and two valves were laying inside an installed Class IE cable tray.

(f)

In the auxiliary building at elevation 543' column 56-FF a Class B pipe was supported by the rungs of an installed Class IE cable tray which was located above the pipe.

The inspector brought all of the above unsatisfactory conditions to the attention of DPC management personnel. Each of the specific unsatisfactory conditions were corrected and the electrical QC department was given directions to start bi-weekly housekeeping

.

.

-4-D inspections of work areas adjacent to Class IE equipment. The inspector was informed that these bi-weekly inspection will continue and will be conducted per CP-371 until sufficient confi-dence can be established to require only monthly housekeeping inspections.

(3) The inspector informed the licensee that failure to inspect and verify adequacy of housekeeping in work areas adjacent to Class IE equipment is contrary to Criterion XIII of Appendix B to 10 CFR 50, as implemented by Duke's Topical Report, paragraph 17.1.13.2 and IEEE 336-1971, section 5.1.2 which requires inspec-tions to be made to verify adequacy of housekeeping in work areas that contain Class IE equipment.

However, since sufficient corrective action has been taken to correct the specific unsatis-factory conditions and action has been taken to preclude repetition, this item of noncompliance, identified as deficiency 413/414/80-12-01 Housekeeping, does not require a written response.

(e) Storage of Class IE equipment; the inspector observed the insula-tion resistance testing of diesel generators 2A and 2B both stators and rotors and reviewed the electrical storage inspection P-3A forms for six other pieces of Class 1E equipment that has specified minimum insulation resistance valves. As a result, the inspector observed that the insulation resistance measuring devices which were being used in conducting the tests did not display tags or marks to show that they had been checked to assure that their displayed readings are accurate. A review of the site procedure which delineates the requirements for the

,

control and calibration of test equipment DPC QA procedure 0-1, chart C-1 does not include requirements for insulation resistance testing equipment to be controlled under the DPC calibration program.

The inspector informed the licensee that all measuring and testing equipment, used in activities affecting the quality of Class IE equipment is to be calibrated for accuracy in accord-ance with a written procedure. Failure to do this is contrary to Criterion XII of Appendix B to 10 CFR 50, as implemented by Duke's Topical Report, paragraph 17.1.12.2 and IEEE 336-1971 section 2.5.2.

This is an item of noncompliance, a deficiency identified as 413/414/80-12-02, Calibration of measuring devices.

The inspector was informed by DPC management personnel that the applicable DPC QA procedure 0-1 chart C-1 would be reviewed to determined if it contains or lists all of the measuring and test equipments that is used in the activities affecting the quality of Class IE equipment.

Except as noted no items of noncompliance or deviations were identified in the areas inspected.
