Licensee Actior on Previous Inspection Findings
(0pcgi) Infraction (50-498/78-16-2; 50-499/78-16-2):
Failure to
Provide 'cceptance Criteria for Megger Testing of Class lE Motors.
The IE inspector reviewed the training records and surveillance
records pertinent to Procedure A040KPECP-2, Rev. O.
These records
indicate that the corrective action has been implemented.
However,
this item will remain open pending completion of the Brown & Root
review of existing inspection plans and procedures for the inclusion
of arpropriate acceptance criteria, per recurrence ccm:rol committed
to in :he licensee's letter of January 8,1979. This action was to
have been completed by February 1,1979.

' . (Closed) Infraction (50-498/78-16-3; 50-499/78-16-3): Failure to follow Approved Procedures for QC Surveillance of Maintenance on Class lE Equipment. The IE inspeci.or reviewed training records and HL&P and B&R surveillance reports pertinent to Procedure A040KPMCP-3, Rev. 4. The corrective action and surveillance of this action is appropriate. This items is considered closed. (0 pen) Infraction (50-498/79-01; 50-499/79-01): Failure to Provide Procedure for a Quality Control Activity for Transcription of Cadwelding Examination Checklist Records. The IE inspector reviewed Site Work Instruction SWI 007-A and a subsequent revision SWI-007-B. The IE inspector advised the licensee's representative that SWI-007-A did not adequately provide the required control on transcription of data from working copies of ECs to record copies. A subsequer.t revision, SWI-007-B was immediately drafted and implemented including training. SWI-007-B does provide adequate instructions for completing and recopying Cadwelding Examination Checklists. This item will remain open pending issuance of a new Cadwelding inspection report as required by recurrence control specified in the licensee's response ledter of March 12,1979. This action was to have been completed by March 20, 1979. (0 pen) Infraction (50-498/79-02; 50-499/79-02): Failure to Control Superseded Drawings. The IE inspec or reviewed the surveillance reports for February and March. These reports indicate that there is a considerable problem with control of FREAs and DCNs and in one report, the IE inspector noted three incorrect drawin9 revisions were found in Control Record Copy 038 which was one of the files orig 1..dlly identified in the 79-02 NRC inspection report. This item will remain open pending results of the continued increased surveillance during April and the subsequert B&R evaluation and action on the results. 3. Site Tour The IE inspectors walked through various areas of the site to observe construction activities in progress and to inspect hotsekeeping and equipment storage. During the tour in the vicinity of the Unit 1 Reactor Containment Building on April 2,1979, the IE inspector observed several instances where reinforcing steel stored in a laydown area was in contact with the ground. On the following day (Arpil 3,1979), additional instances of reinforcing steel stored in contact with the ground in Units 1 and 2 laydown areas were observed by the IE intpector and accompanying licensee representatives. Improper storage of rejryforcing steel was previously identified as an item of noncomplianceH; however, the condition of the laydown storage areas had markedly deteriorated since the problem was first identified.

. During the inspencion of the Unit 1 Mechanical-Electrical Auxiliary
Building (MEAB) on April 4,1979, the IE inspector observed that the skid mounted Boron Recycle Evaporator, which was stored in place, was wet from apparent concrete curing water which was dripping from work areas located above the storage area. The equipa nt was covered by a temporary shelter; however, the shelter failed to provide adequate protection from the wet environment in the MEAB. Rust was observed on the s 'rfaces of many carbon steel components mounted on the skid. In addition, the equipment was observed to be covered with a thin coating of sand and dust which apparently was caused by sandblasting operations which had occurred in the vicinity. The vendor's instructions for the equipment requires that for long-term storase, the unit be stored indoors in a warm, dry environment. The IE inspector informed the licensee that the abcVe item related to the Boron RecMle Evaptrator is considered to be an item of non- compliance with tne requireents of Criterion V of i,ppendix 8 to 10 CFR 50 in that procedures or instructions which prescribe :: ton age of materials were not followed. 4. Review of Heating Ventilating and Air Conditioning (HVAC) Activitic. The IE inspector was informed that Bcwen Industries, Inc., the HVAC contractor, has not begun work on safety related systems. Safety . related HVAC werk is expected to commence in July or August 1979. ' The IE ir spector reviewed Specification No. 3V279VS007-E, " Safety ' Class Ductwork," and Subcontact No. 35-1197-0278, " Heating, Venti- lating and Air Conditioning for Main Plant." The Bowen Quality Assurance Manual reviewed by the IE inspector was an uncontrolled . copy pending completion of the licensee's review and approval of the manual for site use. The licensee stated that the QA Manual and implementing procedures would be issued prior to the beginning of safety related work. _ No items of noncompliance or deviations were identified. 5. Electrical Components and Systems a. Review of Procedures and Records The IE inspector reviewed the following procedures and records pertaining to receiving, storage and maintenance of Class IE , electrical equipment. J g7 335 _s.
. A040KPECP-7, Rev. 3, April 4, 1979, " Receiving, Storage Installation and Maintenance of Class lE and Nonclass lE Lead Storage Batteries" Purchase Order (P.0.) No. 35-1197-4100 for Class lE Battery Chargers Purchase Order (P.O.) No. 35-1197-4109 for Class lE Batteries WMC records for Class lE Batteries El-I and El-Il WMC records for motors 2R161NPA101A, B & C NCR S-Ell 37-A and NCR S-ll37-B for RHR pump motor 2R161NPA101A The IE inspector's review of the maintenance records for the Residual Heat Removal Pump motor and NCR S-Ell 37-A and NCR S-Ell 37-B indicate that the nonconformance report deficiency does not reflect the total scope of the nonconforming con- ditien. 10 CFR 50, Appendix B, Criterion V requires that activities affecting quality shall be accomplished in accordance with upproved instructions and procedures. Brown & Root Quality Assurance Procedure ST-QAP-2.6, "floncon- formances," paragraph 5.1 requires that the description of the nonconforming condition provide sufficient detail establishing the sequence of avents pertaining to the nonconformance and an accurate physical description of the nonconformance. Contrary to the above: NCR S-Ell 37-A and the subsequent revision to the NCR, NCR S-tEll37-B, block No. 7 description of deficiency states: " Questionable Megger Reading on Motor for RHR Pump, Equipment #2R161NPA-101A. ECP-2 and MCP-3.3.5 and 3.6 require 20 megohms on low voltage motors. The meg reading is 250,000 ohms." Based on the IE inspector's review of notes on the back of the WMC record for motor No. 2R161NPA-101A and subsequent discussions with the responsible B&R Quality Control and Engineering personnel, it was found that the motor had been inadequately protected from 7db 3- 7 ,
- . concrete curing water ar- the motor terminal connection box was full of water on February 9,1979. This condition was wit.icssed by QC and later substantiated by the area engineer. The engineer responsible for initiating the proposed disposi- tion on f;CR S-Eli'7A told the IE inspector that he was not aware of the condition o) the motor on February 9, 1979, and was not aware of possibility of there being water in the motor. On March 28, 1979, NCR S-Ell 37-B was written transfarring the responsibility of the resolution of this nonconformance to the Westinghouse site organization. The megger reading for the RHR pump motor on April 4, 1979, was 0.5 megohms, almost two months after the nonconformance was originally identified. The description of the deficiency on NCR S-Ell 37A and NCR S-Ell 378 does not provide sufficient detail establishing the sequence of events pertaining to, and an accurate physical description of the nonconformance to insure proper disposition and evaluation of impact on the condition of Class lE equipment. b. Observation of Work The IE inspector observed the start of the initial equalizing charge on Class lE batteries El-I and El-II. No items of noncompliance or deviations were identified. 6. Exit Interview The IE inspectors met with licensee representatives (denoted in para- graph 1) at tha conclusion of the inspection on April 6,1979. The IE inspectors summarized the purpose and the scope of the inspection and the findings. A licensee representative acknowledged the state- ments of the IE inspectors concerning the items of noncompliance. -7- 3\\1 ...y,. w . ,..~ .;
