RE: Turkey Point Units 3 6 4 Docket Nos.50-250, 50-251 Ins ection Re ort Nos.80-36 and 80-34~F1nddn: Technical.
Specification
6.8.1 requires implementation
of written procedures
and administrative
policies that meet or exceed the requirements
and recommendations
of Section 5.1 and 5.3 of ANSI 18.7-1972 and USNRC Regulatory
Guide 1.33.Procedure 0103.11 requires that following maintenance, safety related systems are restored to their normal condition.
Contrary to the above, during facility tours of Units 3 and 4 this inspection
period, it was noted that maintenance
supervisors
failed to implement existing procedures
to ensure complete restoration
of safety related systems to normal operating condition following maintenance
in that: The Mechanical
Supervisor
on shift during the completion
of maintenance
on Unit 4 blender station failed to have the pipe support between manual isolation valve 4363 and flow control valve 4114A made up and the wooden wedges providing temporary support removed at conclusion
of maintenance
activity.The Mechanical
Supervisor
on shift during the completion
of maintenance
on the Unit 3 Boron Injection Tank failed to have the insulation
over the manway cover~properly replaced at the conclusion
of the maintenance
activity.4~*, 3'.Electrical
Supervisors
allowed the spray t'ight covers for all heat tracing'hermostats.,to
be left,off as a'routine practice instead of properly positioned
.at'the conclusion
of.maintenance
activities.
I\~Res ense:', (1-1)FPL'oncurs
with the'finding.
(1-2)This particular
pipe support was either-inadvertently
omitted due to lack of follow-up or was still in the process of being repaired at the time this finding was noticed.This was found during the hanger and pipe support inspections
and repairs pursuant to I and E Bulletin 79-79-02 which were in progress when Unit 4 was in cold shutdown condition for its annual overhaul/refueling.
(1-3)As corrective
action, the pipe support in question was returned to its original configuration
in December 1980.(1-4)As corrective
action in order to avoid further problems, a procedure is being developed to control removal, reinstallation, and maintenance
of hangers and pipe supports by plant maintenance
forces in order to: a)Prevent recurrence
of the same type of problem., b)~Provide guidelines
for returning hangers and/or'ipe.supports to'their original configura'tion
after their remov'al for maintenance
s
c)Provide guidelines
on the specifications
for each type of bolt on each hangers (i.e., torqueing of bolts)2.(1-5), This procedure is now being formulated.
It is being actively pursued and it is scheduled to be reviewed and approved by April 27, 1981.Full compliance
will be achieved when't is approved.(2-1)FPL concurs with the finding..(2-2)(2-3)The insulation
on the Unit 3 Boron Injection Tank manway cover was not reinstalled
after maintenance
due to lack of follow-up.
As corrective
action, the insulation
on the manway cover in question was reinstalled
prior to January 1981.(2-4)As'corrective
action to avoid further problems, we are taking the following steps: A specific crew will be designated
to maintain each nuclear unit's primary systems.The supervisor
in charge of each crew will be responsible
for compliance
with applicable
plant procedures (including
AP 0103.11)and following up after'is crew completes each job.This responsibility
will.be implemented
by instructing
personnel and dessiminating
job descriptions.
One of the two crews assigned to primary systems will be responsible
for housekeeping.
(2-5)Full compliance
will be achieved no later than March 27, 1981.3.(3-1)FPL concurs, with the finding.(3-2)The practice in the finding developed gradually following several'instances'f
varying degrees of solidification
in boric acid systems~.requiring heat tracing.The Electrical
Maintenance
Department
initiated: weekly checks'f'=each'eat
'tracing'irc'uit
to.'verify.'proper
circ'uit
operation., Many minor.adjustments
and repairs were made as a result of these, checks., Most'of these adjustments
and repairs required access to the heat tracing thermostat
boxes.The practice of not replacing the covers evolved due to the awareness that the cover being reinstalled
would probably be removed again with a week.Also, this practice allowed the shift operators to make minor thermostat
adjustments.
to a circuit during times when Electrical
personnel were not available.
0 (3-3)In order to improve the reliability
and performance
of the heat tracing circuits, the originally
installed Chromalox type heat tracing circuits are being replaced with a much improved Chemelex type.The replacement
program is planned to continue until all heat tracing circuits are replaced.The new type of heat tracing has already proven to be more reliable and to require far less maintenance.
Consequently, for the new circuits there is no need to'leave the covers off.
r0
(3-4).Corrective
action that will be taken;a)Znstallation
of covers which are now available.-
b)The installation
of necessary replacement
covers which have been ordered.c)Meetings within the Electrical
Department
will be held to stress the importance
of the re-installation
of these qovers.d)Preventive
Maintenance
Program plant work orders will be revised to include a specific step calling for installation
of the covers following the work.(3-5)Full compliance
is scheduled to be completed by May 15, 1981.
