Notice of Violation 9617-02
,
Technical Specifications 5.4.1.a. states, in part, that written procedures shall be implemented
j
covering the applicable activities recommended in Regulatory Guide 1.33, Revision 2, Appendix
4 .
A, February 1978. Paragraph 9.e of Appendix A to Regulatory Guide 1.33 recommends written
j
procedures for the control of maintenance.

!
Procedure 01-S-07-1, " Control of Work en Plant Equipment and Facilities," Revision 31, Step
)
6.7.6 states, in part, " Changes to the work package will be handled by one of the following three
methods: (1) Revision, (2) Correction, or (3) Minor correction. A revision to the work order is
classified as an increase / decrease in the scope of the work."
Contrary to the above, on October 28,1996, Work Order 00159564 (clean and inspect 480 voit
i
i
Motor Control Center 21831) was not revised to reflect a decrease in work scope to only inspect
'
the motor control center.

l.
The Reason for the Violation, if Admitted
'
?
I
On 10/27/96 a work order (WO) was released to begin inspection and cleaning of the
11HD bus. Bus 11HD was de-energized prior to commencing the scheduled work.
!
However, Motor Control Center (MCC) 21B31 which is normally powered from the 11HD
,
.
bus, was temporarily being powered from an altamate source. A short time after the WO
!
was initiated, the work scope of the WO was changed to only inspect MCC 21B31
partically due to its energized state. By procedure, the WO should have been revised,
i
this was not done.
in addition, the process for distinguishing an energized MCC was the word ' energized'
written on a slip of paper stapled to the front of the WO. Completion of work on the
,
11HD bus took several shifts. By the beginning of night shift on the 28th, the paper
stapled to the front of the WO to distinguish MCC 21831 as energized had unknowingly
been lost.
1
The electricians began work on MCC 21B31 by first verifying that its feeder breaker was
racked out. However, the fact that the MCC was energized from an attemate source was
not passed along to the electricians during their turnover. Also, due to the fact that the
l
slip of paper that distinguished energized MCCs from de-energized MCCs had been lost,
i
the electricians were unaware that MCC 21B31 was energized. Additionally, the
electricians only checked the feeder breaker for the MCC, they did not use a voltage
'
meter to verify that the MCC was not energized.

Page 2 of 3
On October 28,1996, electricians were performing task under Work Order (WO), which
i
specified to clean and inspect 480-volt Motor Control Center (MCC) 21831. Due to
'
l
factors previously stateddhe_electriciens were unaware of the change in work scope and
i
that MCC 21831 remsined energized. While cleaning in the MCC panels, an electrician
j
{
received a 270 volt electrical shock to his hand. The electrician received no injuries and
no additional treatment was required. Immediately following the event work was
{
stopped, the area was placed in a safe condition, and an investigation initiated.
l
The root cause of this event was inadequate work practices, in that processes in place
j
were not followed and some processes were inadequate.
I
11.
Corrective Steps Which Have Been Taken and Results Achieved
l
Immediate Actions:
1. Work was stopped and the equipment placed in a safe condition,
i
2. The supervisor was summoned to investigate the accident
l
3. The worker was sent to first aid for treatment.
4. All bus work was placed under one supervisor.
5. Safety meetings were held to warn technicians of the potential for injury and their
responsibility to verify the bus is de-energized prior to work.
l
These immediate corrective actions were followed up by programmatic changes to
ensure this concem is addressed for the long term.
Ill,
Corrective Steps to be Taken to Proclude Further Violations
Long Term:
1. Work Package Needs Improvement:
Change 01-S-07-1 to clarify management's expectation that WO impact statements must
i
reflect work scope changes and actual plant conditions or be retumed to planning for
revision.
2. Pre-Job Briefing Needs improvement:
i
l
Ensure that supervis;on is performing adequate pre-job briefs and tum-overs. Pre-job
briefs and tum-overs will be monitored periodically as determined by the I&E
Superintendent with the concurrence of the Manager of Maintenance.

4. Procedural improvement:
A procedure will be written to perform the cleaning and inspection preventative
maintenance for MCCs only during a de-energized condition.
