    ' (Closed) Unresolved Item (5C-334/85-27-03): The "B" Component' Cooling l     ; Water,? ump motor was declared inoperable on November 1, 1985, due to high lube M1 temperatures. After several unsuccessful licensee attempts to
    / identify:and correct the problem, unresolved item 85-27-03 was initiated for NRC Region I to track the corrective actio ,
          '

s The' licensee's continued investigation of the problem was documented in Report No. N02MEL: 0071, dated February 3,1986, which stated in part that the overheating was due to misalignment of the pump and moto Corrective action included realigning the motor and opening the inboard i' bearing gap to 7 mils. The report went on to state that the motor performance was acceptable following the. corrective actio Subsequently,

the inspector's review did not identify further discrepancies in the motor's performance following the licensees corrective actio ! , Based on the above, this item is close .0 Maintenance Review i

Control Room Air Conditioning Unit, AC-1A,

,
 *

Fuel Pool Purification Pump and Motor, "A",'and

 *

Feedwater Regulating Valve, FCV-FW-47 During the performance of work on these components, the inspector specifically verified the following attributes:

 *

Maintenance activities were authorized by Operations personnel prior to the beginning of work; > '

 * Maintenance personnel conducting the work were familiar with the ongoing job;
.  *

QC coverage appeared to be adequate;

 *

Procedures were followed where applicable;

 *

Requirements specified on Radiation Work Permits (RWPs) were followed where applicable;

 *

Maintenance personnel established cleanliness controls appropriate for the' work;

 *

Housekeeping control of job sites was adequate;

 *

Serial numbers and calibration dates of maintenance and test l equipment used for the job were recorded in the applicable controlling documents; i

Printouts for individual components were also obtained which described in detail the failure description and-corrective action, as well as other pertinent maintenance informa-tion. This maintenance data base is supplementary to the microfilmed' i maintenance packages maintained by plant records.- The inspector i concluded, after his review of the requested historical maintenance i information, that the attributes listed in paragraph 3.1 of this report are adequately addressed in the available work documentatio Based on personal observations of the ongoing work, the inspector l concluded that the three activities observed were conducted in accordance with the requirements identified in paragraph 3.3 of this repor The inspector did question maintenance personnel during-testing associated with work on the control room air conditioning unit concerning the possible hazards of inhaling Refrigerant-12 which-was discharging into a closed space during the test. The inspector observed that the maintenance personnel exhibited no apparent concern even though a rather large amount of Refrigerant-12 was discharging into the test area through a leaking flange. These maintenance personnel later stated to the inspector that they sho,uld be careful not to be exposed unnecessarily to the vapors. The inspector discussed this concern with management, who indicated that the matter would be examined in order to ensure safe work practices.~ The inspector had no further question During his review, the inspector held discussions with various'sife personnel in order to determine the conduct and effectiveness of the Preventive Maintenance (PM) program at BVPS Unit 1. The inspector subsequently concluded that PM trending analyses of plant. components are performed on a reactive basis and are not part of an ongoing program for most components at the site. The inspector did identify several instances where components were.added to the PM program after work performed under corrective maintenance MWRs had identified activities that could be addressed on a preventive basis. One example -

-
.

i of.this type'was noted by the inspector during a: review of .. l maintenance activities performed on the "A" Low-Head Safety Injection -{ Pump, where securing nuts for the wedge control rods were periodi- j cally tightened under corrective maintenance MWR The inspector . observed that a periodic inspection of these nuts had been initiated ! on a preventive maintenance basis indicating a responsiveness of maintenance personnel to a preventive maintenance philosophy, } g No violations or deviations were identifie .0 Quality Assurance / Quality Control (QA/QC) - The inspector held discussions with Quality Control (QC) personnel; reviewed maintenance procedures and MWRs; and observed ongoing work in order to ascertain QCs role in maintenance. The inspector determined that QC coverage of maintenance activities were adequate,'and that QC inspectors are familiar enough with the maintenance activities to perform their function properly. In addition, maintenance work requests and _

     :

maintenance procedures have an appropriate number and placement of hol ~

      '

points in order to assure adequate inspection of the wor No violations or deviations were observe l l 5.0 Exit Meeting  ! The inspector met with licensee representatives (denoted in paragraph 1.0) l l at the conclusion of the inspection on September 4, 1987. During this- ' exit meeting, the inspector summarized the. scope and findings of the inspection as described in this repor j i At no time during the inspection was written. material provided to the _l licensee by the inspector. The licensee did not identify any information 1 presented as being proprietar i
