Areas Ins ected:
Routine fire protection inspection of surveillances,
equipment, fire brigade training and drills, and fire protection audits.
The
inspector utilized selected
portions of NRC inspection procedure
64704,
92902,
and 92904.
Results:
Overall, fire protection
program activities were effectively
implemented in meeting the safety objectives of the program.
The fire
protection program
was rated excellent
and improving.
The staff was
experienced
and knowledgeable
and had taken appropriate
actions to correct
most issues
and problems.
Strengths
included
a low number of impairments;
a
dedicated
and well-trained fire brigade; the staff was being proactive in
improving and maintaining fire protection equipment;
and the audits performed
were good.
A violation was identified for the failure to remove combustible
materials within 35 feet of a "hotwork" activities (paragraph 3.4).
Additional weaknesses
observed
during this work activity was the use of
herculite
and untreated
wood for a barrier.
In addition, the fire watch, fire
brigade,
and maintenance
supervisors
did not enforce the 35 foot combustible
free zone during their duties.
A weakness
noted during the fire drill was
that updated fire strategies
(pre-fire plans)
were not made available to the
fire brigade;
however,
updated
plans
are currently in the process of being
issued.

2.3
Closed Violation 315 316 93015-01:
This item addressed
a violation for
improper scheduling of preventive mainten'ance
tasks which were
aut'omatically scheduled late due to computer software, that used the job
order close out date for scheduling rather than the date the preventive
maintenance
(PM) task was actually performed.
A tracking system
was
implemented for the
PM tasks which is reviewed
by management
on
a daily
basis to ensure timely close out of items.
Those
items that are delayed
beyond the scheduled
cycle are manually rescheduled
to fall within there
normal preventive maintenance
cycle.
The tracking system
had cor rected
the stated
problem and this item is closed.
Closed
Violation 315 316 93015-02:
This item addressed
a violation
for not properly controlling outdated
maintenance
procedures.
The
licensee
performed
a 100 percent
inspection
on the procedures
in
question.
The above problem was corrected
by causing the group making
a
major document
change in a site library, responsible
to ensure, that
documents
no longer used are sent
back to the issuing group, which
ensures
removal
from the site library.
No new problems of this type had
been found.
This item is closed.
Closed
Violation 315 316 93015-03:
This item addressed
a concern with
preventive maintenance
being delayed for an extended
period of time
resulting in no corrective actions for inoperable
emergency lights in
the plant.
Extensive actions
had
been taken to resolve
emergency
3.0
lighting problems
and surveillances
are
no longer delayed
beyond their
normal cycle.
Those
new problems identified with emergency lighting
were corrected
in a timely manner.
This item is closed.
Routine Fire Protection
Pro ram Review
3.1
This inspection consisted of plant area observations
and reviews of fire
protection surveill.ances,
maintenance
on fire protection equipment, fire
brigade training and drill.s, fire reports, deviation reports,
work
requests,
safety evaluations,
and audits of fire protection activities.
Plant Area Observations
The inspector toured the areas of the turbine building, the screen
house,
and the
new fire pump building to observe
the adequacy
and
control of combustibles, fire doors,
hose stations,
detection
equipment,
extinguishers,
sprinkler systems,
emergency lights,
and housekeeping.
With the exception of "hotwork", the control of combustibles
in the
plant was good.
This included control of transient combustibles.
A
minimal amount of combustible materials
was noted in storage
cages.
Flammable liquids were stored in safety cans.
Most wood and plastics
used in the plant were fire resistant.
Equipment oil leaks were minimal
with oil being collected
on absorbers
and removed before
becoming
excessive.
3.2
The material condition of most fire protection equipment
was good.
This
included dampers, fire extinguishers,
hose stations,
and fire pumps.
A
new building with new diesel
and electric fire pumps
had
been built
onsite with a dedicated
water supply to ensure that biofouling would not
effect the reliability of the fire protection
system.
Most fire doors
in the plant were in excellent condition which included self-closure
and
latching.
A site locksmith contributed to timely door repairs.
A fire
protection
system valve replacement
project is in the planning stage to
correct problems with leakage
when isolating specific sections of the
fire protection systems for maintenance.
Surveillances
indicated that
fire protection system equipment condition, for those surveillances
reviewed,
appeared
to be good, except for emergency lighting.
A large
number of emergency lighting failures were occurring
as
a result of
battery design.
The batteries
were replaced
when they fail.
Extinguishers
had been inspected
and had
a current inspection date.
Fire fighting foam was being replaced prior to the expiration date.
A
new fire truck had also
been
purchased
during this assessment
period.
The plant was clean
and housekeeping
was good.
Transient combustibles
were being tracked
by a computer tracking system, with a daily update,
and calculations
were being maintained for fire loading in plant areas.
Compensatory
actions
were taken for those
areas
exceeding
the fire
loading requirements.
Inoperable fire barrier penetration
gap seals
are currently
a major
problem.
A barrier gap seal
was found with untreated
styrofoam behind
the outer silicon sheeting rather then
a required fire barrier material.
3.3
A proactive program was started to inspect
485 additional
gap seals.
So
far
42 additional
gap seals
were found with untreated
styrofoam
and were
being repaired during the inspection.
Appropriate compensatory
measures
were taken
by assigning
a one hour fire watch until barrier gap seals
were repaired.
Also, minimizing the risk to the plant were fire
detection
and fire suppression
available in most the effected areas.
A
review of other impairments indicated that the plant had
been proactive
in getting impairments repaired.
The plant had very few impairments,
excluding the recent
gap seal
problems.
Fire Watches
3.4
Missed fire watch inspections for impairments
had
been
a problem during
the early part of this year.
A new contractor
had
been hired;
As
a
result
new fire watches
lacked training and
an awareness
of the
importance of their fire watch responsibilities.
These
problems
were
corrected.
Some of the contractor's
employment
was terminated
when they
did not measure
up to expectations.
The licensee
took additional
corrective actions
as needed.
An improved fire watch training program
was implemented to enhance
the learning of fire watch tasks.
In
addition, all supervisors
are
now required to identify new impairments
(and its location) to fire watch personnel
to ensure
the correct areas
are inspected.
On a sample basis, fire protection
management
were making spot checks to
ensure that fire watches
were doing their job.
guality assurance
(gA)
sur veillances
were also being conducted
on the fire watches
as they made
their inspections.
No problems with the one hour fire watch requirement
bei'ng violated were found during these
gA surveillances.
The corrective
actions for the fire watch problems
appeared
to be effective.
Weldin
and Cuttin
Permits
There were
a significant number of fires in the plant during the
assessment
period.
The inspector reviewed the fire reports
and noted
that
a larger than normal
number of fires had occurred during "hotwork"
with most fires occurring near the work indicating that combustible
controls for "hotwork" were not being implemented.
During a tour of the turbine building with the fire protection
supervisors,
the inspector
observed
"hotwork" (welding, grinding,
cutting activities) at three job locations were not being performed
according to plant procedures
and good work practices.
Two job
locations contained
an untreated
wood frame supporting herculite for a
barrier.
In addition, the areas
contained
a garbage
can with
combustibles,
cloth tool bags,
coats,
papers,
boxes, plastic buckets,
and other combustible materials.
D. C.
Cook Technical Specification 6.8.1.a requires
adherence
to fire
protection
program implementing procedures.
D. C.
Cook Preventive
Maintenance
Inst'ruction,
PMI-2270, "Fire Protection," Revision 22,
requires
the following:
As a minimum the following items shall
be reviewed:
4.3.2.1
Removal of combustibles
from the immediate
area in which the work is to be performed
and
a
35'adius
around the work area,
not to include those
areas
cut off by walls, doors, etc.
4.3.2.3
The
necessity to use non-flammable material to cover or
shield adjacent
or lower equipment
and openings to
lower elevations.
On June 3,
1994, the inspector
observed grinding, welding,and cutting
activities in the turbine building that did not have combustibles
removed or covered within 35 feet of these activities.
This is
violation of Technical Specification 6.8. l.a(50-315/316/94012-01(DRS)).
A response
to this violation is required.
The plant determined that the employees
had received
adequate
training
but over the years the general
condition of not enforcing the 35 foot
combustible free zone
had
become
an accepted
practice.
The problem of
not enforcing this requirement
included the fire watches,
the fire
brigade,
the supervisors of the maintenance staff,
and the maintenance
employees.
However, mitigating the significance of this problem were
"hotwork" fire watches
who were
on the job site and attentive to their
duties.
3.5
The immediate corrective actions
were to inform the staff that the 35
foot combustible free zone would be enforced.
Naintenance staff that
did not comply would have the work stopped.
Ninor amounts of
combustibles
would still be needed
near the work, such
as work
procedures,
cloth work bags,
and plastic quench bottles of water.
But
in. most cases
these
items
can
be protected or covered.
Fire Protection Staffin
The staff was experienced,
knowledgeable,
and proactive in dealing with
most plant problems.
Good cooperation
was observed
among the staff.
The fire protection supervisor
was very knowledgeable
about the fire
protection
program
and Appendix R.
Since the previous fire protection
inspection
a dedicated fire protection training instructor,
a fire
protection engineer,
and
a second fire protection coordinator
had been
added to the staff.
In addition,
an Appendix
R special project team had
been created.
3.6
Fire Bri ade
The plant requirements for the fire brigade were all being met in an
effective manner.
The inspector
reviewed fire brigade qualifications
and associated
training records.
Onsite fire drill requirements
had
been
met by all brigade
members
who were listed as qualified.
Live fire
training for all brigade
members
was being conducted
on an annual
bases.
Good fire brigade"critiques
were being performed for fire drills with
associated
training to improve brigade performance.
Also, off-site
response drills were being performed
and
a good relationship existed
with the local fire department.
The fire brigade training program appeared
to be good.
A review of
records indicates that the fire brigade
was meeting its quarterly fire
brigade training.
Hembers of the fire brigade
had sufficient training
3.7
on .plant safety-related
systems with the assistance
of the operations
department
to understand
the effects of a fire on safe
shutdown
capability.
The inspectors
observed
a fire drill in the auxiliary boiler room.
The
operations
and fire fighting staff appropriately
used the pre-fire plans
to identify the risks in the area
and simulated isolating the electrical
equipment in the auxiliary boiler room.
Five fire brigade
members
responded
in a timely manner to the simulated fire with appropriate fire
fighting gear
and completed dressing for entering the space.
Fire
fighting gear
was in good condition and well organized.
The operations
and security departments
also responded
to the fire drill.
Four brigade
members
formed double
hose
teams with the simulated
use of foam to fight
the fire.
The overall
assessment
of the drill was excellent.
One weakness
noted
was the pre-fire plans
had not been
updated to reflect the
new
electrical control panel modifications for the auxiliary boiler room.
Additional time with operations
assistance
was required to ensure that
the areas
equipment
was properly isolated prior to fighting the
simulated fire.
The pre-fire plans are currently being updated
and will
be issued to the plant staff.
A critique was held at the end of the fire drill with all of the
participants in the drill present.
The participants
were allowed to
give their insights
on what they considered
as problems during the
drill.
The staffs overall
assessment
was that this was
an excellent
drill with very few problems.
Audits and Self-Assessments
of Fire Protection
Audits were detailed
and thorough with adequate staff hours devoted to
each audit.
The gA surveillances
were performance
based
observations
of
conditions in the plant and were effective in identifying fire
protection
program problems.
The audits included good findings and
recommendations
to improve the fire protection program.
The 1994 fire
protection audit was very comprehensive
with 5 quality assurance
auditors
spending
3 weeks onsite.
The findings and recommendations
had
been
used to improve the fire protection program.
The following audits
were reviewed:
