d.
(Closed) Violation (373/84-32-01; 374/84-39-01):
Inadequate control of measuring and test equipment (M&TE).
The inspector reviewed the control of M&TE in the electrical, mechanical, and instrument and control (I&C) areas.
M&TE accountability logs were reviewed, personnel assigned to control M&TE were interviewed, and equipment storage areas were inspected.
The control of M&TE is much improved and appears to be adequate.
The licensee has assigned a dedicated management person responsible for the M&TE in each maintenance department as stated in the licensee response to the violation, dated February 1,1985.
.
e.
(Closed) Open Item (373/84-32-02; 374/84-39-02):
Implementation of a new system to control M&TE in the electrical area.
During the inspection that this item was identified, the licensee initiated a new system to control M&TE.
As indicated in Section 2.d, controls established in the electrical area for M&TE appear to be adequate.
f.
(Closed) Violation (373/84-32-03; 374/84-39-03):
Significant trends in discrepancy finding were identified but not reported.
As stated in the licensee response to this violation, dated February 1, 1985, procedure LTP 200-8 was revised to require a discussion in the quarterly summary report of discrepancy reports of the cause of an increase in the number of discrepancy reports. The inspector verified from review of the quarterly reports that summaries of increasing trends are being performed and reports are being forwarded to management personnel.
The inspector has no further concerns regarding this item.
g.
(Closed) Open Item (373/84-32-04; 374/84-39-04):
Management review of trending program. With the improvement in trending and reporting of discrepancy reports described in Section 2.f, management review cf the trending program has increased.
The inspector has no further concerns regarding this item.
h.
(0 pen) Open Item (373/85027-01; 374/85028-01):
Implementation of
" Vendor Technical Information Program" (VETIP) per procedure LAP 100-15.
The implementation of VETIP was proceeding and was approximately 60% complete.
This item will remain open pending further NRC review when implementation of VETIP is completed.
i.
(Closed) Violation (373/85027-02; 374/85028-02):
Failure to use required procedure when taking equipment out of service.
The inspector verified that the Plant Manager had written a letter to all Department Heads directing discontinuance of the practice of posting an operator at a control device in lieu of hanging an out-of-service card, as described in the licensee response to the violation, dated October 1, 1986.
The inspector verified through interviews that personnel were aware of the instruction on out of service and were complying with it.

j.
(Closed) Open Item (373/85032-01; 374/85033-01):
Expansion of component failure trending program.
The licensee's trending program is structured to identify trends based on individual component failures within specific plant systems.
The licensee reviewed the program to determine if it could be expanded to identify failures of specific equipment types which are common to several plant systems.
With the present computer software, the licensee determined that the trending could not be expanded.
Any type failures can be recalled on an individual basis from the maintenance history.
The licensee plans to utilize this type recall in conjunction with failures identified on specific components by the trending program to identify possible generic component failures.
k.
(0 pen) Open Item (373/85032-02; 374/85033-02):
Control of lubricants.
The licensee has reviewed his lubricant control program and formulated plans to improve it.
A lubricant control procedure remains to be written.
The licensee plans to have the procedure written and implemented by October 1, 1986.
This item will remain open pending NRC review of the program after implementation.
3.
Maintenance Assessment Followup During October, November, and December 1985, a special, in-depth assessment of maintenance activities at the LaSalle Plant was performed and is documented in Inspection Report No. 373/85032; 374/85033.
Nine recommendations for improvement in the licensee maintenance program were made in the inspection report. On May 28, 1986, the licensee made a presentation to the NRC, in the Region III office, of actions in progress and planned in response to the recommendations.
During this inspection, the inspector reviewed the progress the licensee had made on these recommendations.
Information was obtained by the inspector through interviews, attending various meetings, and reviews of records and procedures.
The nine recommendations, the licensee's proposed actions, and the status of these actions are as follows:
10 pen) Recommendation (373/85032R-01; 374/85033R-01):
a.
Evaluate the effectiveness of management activities relative to the engineering support groups, radiation protection organization, and the maintenance organization to ensure maintenance personnel receive correct information, appropriate support, and guidance to perform their assigned duties.
Proposed Actions Increase the Architect Engineer (AE) involvement in the plant
modification process by physical observation in areas where modifications are to occur, performing walkdown of Engineering Change Notices (ECN) to modifications, and increase site field engineering support.
Assign a cognizant Technical Staff Engineer to each
modification.
-

.. _. --
.
.
Provide additional radiation protection manpower support and
involve radiation protection in work planning.
Status The AE has increased their involvement in the modification process.
For a time, 12 persons were performing walkdowns of ECNs.
A cognizant Technical Staff Engineer has been assigned to each modification.
Most people interviewed indicated radiation protection support had improved.
Also, it was indicated in interviews that Station Nuclear Engineering Department (SNED)
support for the plant has improved and increased.
b.
(0 pen) Recommendation (373/85032R-02; 374/85033R-02):
Expedite the statusing and reduction of work request backlog.
Proposed Actions Review work request backlog and establish accurate
accountability of the backlog.
Define acceptable and optimum backlog of non-outage
work requests.
'
Establish a work request status reporting system.
- Add sort capability for corrective, preventive, facility,
and modification work requests.
Status All the above actions have been implemented.
As a result, the status of the work request backlog is much better defined.
The actual backlog was still significant due to both plants being in an outage at the same time.
There were 2494 work requests outstanding on July 15, 1986.
c.
(0 pen) Recommendation (373/85032R-03; 374/85033R-03):
Evaluate the effectiveness of the preventive maintenance (PM)
program.

Proposed Actions Make contact with other utilities and obtain copies of their
PM programs.
'
General Electric operation engineer is to be assigned to
j LaSalle with PM experience.
