During the inspection period',
the inspectors
observed
and
examined
activities",to Ver'ify the operational
s'afety of the licensee's
facility." The observations
and examinations
of those activities
were conducted
on
a daily, weekly','- or monthly basis.
On
a daily basis,
the inspectors
observed
control room activities
to verify the licensee's
'adherence'o
limiting conditions for
operations
as prescribed
in the facility Technical Specifications.
Logs, intrumentation,
recorder
traces,
and other operating
records
were
examined
to obtain information on plant conditions,
trends,
and compliance with regulations.
The turnover of information
on plant status
was observed
to determine
that all pertinent
information was relayed.
During each
week,
the inspectors
toured
the accessible
areas
of
the facility to observe
the following items:

During each

and: other plant personnel.
'The discussions
centered
on pertinent
topics relating to g'eneral plant conditions,
pro-
cedures,
securit'y, training,
and other topics aligned with the
work activities involved.
The inspectors
examined
the licensee's
nonconformance
reports
to confirm the deficiencies
were identified and tracked
by the
system.
Identified nonconformances
were being tracked
and followed
to the completion of corrective action.
t
No items of noncompliance
or deviations
were identified.

Maintenance
Maintenance activities including both preventive
and corrective
maintenance
were reviewed
by the inspectors
during the month.
Observations
by the inspectors verified that proper approvals,
system clearance
and tests
of redundant
equipment
were performed,
as appropriate,
prior to maintenance
of safety related
systems
or components.
The inspectors verified that qualified personnel
performed
the maintenance
using appropriate
maintenance
procedures.
Replacement
parts
were
examined
to determine
the proper certifi-
cation 'of materials,
workmanship
and tests.
During the actual
performance
of the maintenance activity, the inspectors
checked
for proper fire protection controls
and housekeeping,
as approp-
riate.
Upon completion of the maintenance activity, the inspec-
tors verified that the
component
or system
was properly tested
prior to returning
the system
or component
to service.
During
the inspection period,
maintenance
activities associated
with
the safety injection
pumps
were observed.
During reviews of the control operator's
log several
inadver-
tant safety injection events
were noted
(no water
was injected
into the reactor vessel).
Upon investigation of the last of these
events, it was determined
that the
use of an inadequately
re-
viewed
and approved
procedure for maintenance
on the solid state
protection
system
was
the root cause
of the inadvertant
safety

Surveillaxice""
A
The surveillanc'e testing of safety-related
systems
were reviewed
by the inspectors.-
Observations
by the inspectors
included veri-
fication that proper procedures
were used,
test instrumentation
was calibrated
and that the system
or component
being tested
was
properly removed
from service if required
by the test procedure.
Following completion of the surveillance
tests,
the inspectors
verified that the test results
met the acceptance
criteria of the
'echnical
specifications
and were reviewed
by cognizant licensee
personnel.
The inspectors
also verified that corrective action
was initiated, if required,
to determine
the cause for any un-
acceptable
test results
and to restore
the system
or component
to an operable
status
consistent
with the technical specification
requirements.
Surveillance
tests
witnessed
during the inspection
period were associated
wi,th the residual
heat
removal
pump.
No items of noncompliance
or deviations
were identified.
