Action on Previous Inspection Findings {Open) Violation (237/85008-01; 249/85007-01):
Failure to complete work request (WR) packages in accordance with approved procedure Although good progress had been made by the licensee to correct the identified deficiencies, not all had been resolved completely at the time of this inspectio Examples included several WRs which were found to be missing information, such as TJM codes and signature Pending complete corrective action, this item will remain ope (Closed) Open Item (237/85008-03; 249/85007-03):
Storage of a large backlog of comRleted WR packages in two rooms that did not meet the requirements of ANSI N45.2.9 (1974).
The licensee has eliminated the backlog and is now meeting the requirements of ANSI N45. The inspector was satisfied with the licensee's corrective action taken in this are (Closed) Unresolved Item (237/85008-04; 249/85007-04): Ability of the Quality Control Department to adequately support maintenance during periods when the work load is very hig An increase in the size of the plant QC staff and the availability of 11 loan 11 QC inspectors has satisfied the inspector that the QC coverage is adequat *
- Maintenance Assessment The primary purpose of this inspection was to focus on the licensee's progress in addressing those issues previously identified in NRC Inspection Reports No. 237/85008 and No. 249/85007. During that inspection, several observations were made regarding implementation of the Dresden maintenance progra The observations dealt with reduction of the work request backlog, effective management and supervision of craft personnel, reduction of maintenance personnel errors, QC inspection staffing, and trainin In addition to determining the present status of these items, the preventive maintenance and maintenance history programs were also reviewed during this inspectio The assessment consisted of interviews with plant personnel; review of administrative and maintenance procedures, documents, and records; and review of selected work requests. A brief synopsis of each topic's status, including additional concerns and observations, is presented in the following section The licensee is presently developing a computerized maintenance history progra The proposed program has the ability to recall work request (WR) information by equipment identification number for hi story and trend.i ng purpose The current trending program at Dresden is structured to identify trends based on individual component failures within specific plant system This type of trending does not identify failures of specific equipment types which are common to several plant system This issue was discussed with licensee personnel; they stated that it was currently being addresse Pending review of the licensee's actions, this matter is considered open (237/85040-01; 249/85038-01).
Dresden Administrative Procedure (OAP) 4-3, Revision 0, describes*
the procedure to be used for equipment history and trending by the mechanical, electrical, and. instrument department Interviews with the Master Mechanic, Master Electrician, and Master Instrument Mechanic revealed that each were performing a semi-annual scheduled review of the past six months of completed work requests for trending purposes; however, the results and subsequent recommendations of the WR review were not being documente All three maintenance depart-ments have agreed to document these review This item is considered open pending further review (237/85040-02; 249/85038-02). The inspector reviewed preventive maintenance (PM) scheduling activities. During the review, several PM and surveillance activities appeared to be past du Licensee personnel stated that activities in question were most likely complete, but that the computer had not been update The licensee is in the process of verifying the informatio This is considered an unresolved item pending further revie (237/85040-03; 249/85038-03).
- The number of open maintenance work requests compared to other sites, continues to be higher than average. Although some progress has been made to reduce it, further concentration of resources to reduce the backlog and maintain it at an acceptable level appears warrante Licensee personnel stated that approximately 20% of the maintenance time in the plant was spent performing preventive maintenance, with the balance of time being spent performing corrective maintenanc The present scope of the PM program does not ensure that all equipment required for safe, reliable plant operation is systematically irispected, cleaned, lubricated, tested, and adjusted as necessar The PM program is not well defined, in that it is,
segmented into several program PM scheduling is presently performed by each maintenance discipline rather than having one individual responsib1e for the scheduling of all PM activitie Appointing one responsible individual would provide a cohesive element to the program and improve its administratio The licensee's maintenance program is essentially corrective in nature. This approach leads to a reduced plant reliability because, as a rule, equipment is not effectively serviced except when it fail Even though some aspects of the present program predicts equipment failures, systematic redirection of the present corrective maintenance philosophy to a more predictive preventive maintenance approach would provide improved plant reliabilit Interviews with management revealed that there did not appear to be adequate management involvement in analyzing all scrams, deviation reports (DVRs), and LER Specifically, the identification and trending of information, such as equipment failures and personnel errors, did not appear to be provided in such a way to be beneficial to managemen Trending of this type would provide management personnel with another tool to gauge areas where improvements in plant maintenance are neede.
Recommendations Overall, the inspector found that implementation of the maintenance program showed evidence of improvement, but that further progress was neede Consideration should be given to the following recommendations: Expedite the implementation of an effective maintenance history and trending progra Expedite the reduction of the work request backlog and provide the necessary resources to ensure that it is maintained at an acceptable leve Evaluate the scope and effectiveness of the PM program and take those actions necessary to redirect the present corrective maintenance philosophy to a more predictive maintenance approach.
... Provide better information relative to and trending of those indicators of plant reliability and operations which would benefit management personnel in their oversight responsiblitie.
Open Items Open items are matters which have been discussed with the licensee, which will be reviewed further by the inspectors, and which involve some action on the part of the NRC or licensee or bot Two open items were disclosed during this inspectio.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, violations, or deviation One unresolved item was disclosed during this inspectio.
Exit Interview The inspectors met with licensee representatives listed in paragraph 1, on December 19, 1985, and summarized the purpose, scope and findings of the assessmen The inspectors discussed the likely information content of the inspection report with regard to documents or processes reviewed by the inspectors during the assessmen The licensee did not identify any such documents or processes as proprietary.
