The master electrical, n.echanical and instrument rcechanics indicated during interviews with the inspector that during tatigate treetings (group meetings) errphasis was placed on having maintenance procedures at the job site. A QC inspector indicated that procedures were usually at the job site. Resident inspectors normally observe this activity during tours of the plant. This item is c1csed.

Irplementation of DAP-2-10 was approximately 65% corrpleted. There were approximately 100 rrar.uals left to be reviewed and approved.
This activity was con.pleted at the rate of abcut five per week.
If a technical tanual was not approved, but needed for e maintenance activity, DAP-2-10 required the n.anual to be reviewed for technical adequacy prior to use.
Due to the length of the plant cutage,

The inspector verified that, as stated in the licenste response dated November 15, 1985, a change had been made to DTS-300-2 to require docunentation of test results. Also, as stated in the response, a procedure change was made to DAP 9-3,
" Procedure Peview and Writing" that included a requirement for all surveillance or test results to be reviewed with reference to known acceptance criteria.
This review, alcng with the acceptance criteria, was to be documented. The inspector reviewed three recently completed DTS-300-2 surveillance tests and verified that the test results and evaluations were documented. This item is closed.

The licensee reviewed the program to detern. ire if it cculd be expanded to identify failures of specific equiptrent types that were conr.on to several plant systems.
The licensee determined that the trending could not be expanded with the current computer software. All failures could be recalled on an individual basis from the maintenance history. The licensee plans to utilize this type recall in ccnjunction with failures identified cn specific conponents by the trending progrcm to identify possible generic compcnent failures.

The licensee determined that these activities were not required by technical specification and appeared to be past due because the ccmputer tracking system was the same as the one used for technical specification required activities. The licensee changed the tracking system for non-technical specification activities; the current status of those activities was provided.
The inspector reviewed the current status of non-technical specification PMs and surveillances. The inspectors determined that the PMs and surveillances had been generally performed as specified.
For iteras that were overdue, a monthly report was prepared and the respcnsible department notified. A review of Licensee Event Reports (LERs), during the time the unresolvt.d item was identified, indicated that there were no overdue technical specifications required surveillances.

During March and April 1985, a special, in-depth review and evaluation of maintenance activities at the Dresden Plant was performed. As dccutented in Inspection Report tio. 50-237/85008; 50-249/85007 seven recontrendations were made by NRC. A folichup inspecticn was performed
,
in Decenber 1985. As documented in Inspection Report tio. 50-237/85040; 50-245/85038 four recomendaticns were made by NRC.
The licensee responded to the four recomendations in a letter dated Farch 11, 1986.
During this inspection, the inspector reviewed the status of these eleven NRC recomendations.
Infonration was obtained by the inspector through interviews, attendance at a tailgate meeting, and reviews of records and procedures.
Results are as follows:

In the liFeh'seE's TcFTl~,~ 986,- response to this item, a backlog goal of less than 1100 corrective work requests was set. This goal was not achieved. During 1986, the backlog was reduced to-approxirnately 1200 on two occasions; however, the backlog increased because of extended outages for Units 2 and 3.
At the time of this inspection, the backlog of work requests was approximately 1800.
The resident inspectors continually track the work request backlog.

Basic non-nuclear training, which is applicable to both nuclear and fossil plants, was still given to nuclear and fossil personnel in the same classroom. The Training Center now provides sorte nuclear specific training to nuclear personnel. The Dresden Maintenance Training Program, which was accredited by INP0 in January 1987, provides irost of the nuclear specific training at the Dresden Plant.
Interviews with the n, aster rr.echanics by the inspector indicated there was continuous training of maintenance persennel with up to 20*. of the time devoted to training. This reconwendation is closed.

The licensee indicated that work requests for the past three years were included in the coroputer history. All current work requests were entered when initiated and completed. The trending program was not completely implemented. As indicated in Paragraph 2.g, a new procedure for the revicw of trending information would be written. The reconcendation is closed.

The licensee's March 11, 1986, response to this item described several steps that had been taken to aid management in oversight respcnsibilities. Although not specifically discussed in the response, the licensee initiated a Dresden Station k'eekly Report. This report incluc.. J inforvation and trer.ds abcut reactor i

It appeared to the inspector to be an effecthe report to keep all levels of managerrent informed of reliability and other plant probhnis. This recorrrrendation is cicsed.
