Docket Nos. 50-250, 50-251 Ins ection Re ort Nos.

~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.

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.

(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 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.

(3-1)
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.
r 0
(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.
