Exit Interview
The inspection
scope
and findings were summarized
on August 10,
1979 with
those persons
indicated in Paragraph
1 above.
Based
on a request
by the
inspector,
licensee
representatives
committed to reviewing, by September
15,
1979, all nonvital loads
on "D" Motor Control Center. This reviev would
focus on the corrective action that could prevent occurrences
such as the
August 3,
1979 trip of Unit 3 and thus result in the reduction of unnecessary
challenges to the safety systems.
Licensee Action on Previous Inspection Findings
Unresolved item 50-250/79-24-02 is upgraded to an item of noncompliance
(50-250/79-26-02).
For more information see paragraph
9 of this report.
Unresolved Items
Unresolved items were not identified during this inspection.
Followup on Reportable Events
The following events were reviewed to ascertain that:
a.
reporting requirements
were met;
b.
corrective action was taken as required by Appendix B to 10 CFR Part 50;
indication.
This resulted in a reactor trip on high pressurizer
pressure.
At the time, neither of the two pressurizer
spray valves
was available.
One was considered
inoperable prior to the transient
and the other, temporarily powered by the non-vital portion of MCC-D
had become unavailable earlier as
a consequence
of the Unit 4 trip..
A review of the pressurizer
spray valves disclosed
inadequacies
in the
administrative controls over the correction of operational
problems
exhibited by spray valve PCV"3-455B.
The original Hagan controller
for spray valve PCV-3-455B had been disconnected
and was. replaced
by
another manual controller which was plugged into the valve control
circuit and which had been taped to the top of a console in the main
control room.
No temporary procedure
had been promulgated to ensure
consistent
understanding
between shifts of the operational control of
this unusual
component configuration.
The lack of a temporary proce-
dure indicates that A.P.0109.6,
"Temporary Procedures",
was not fol-
lowed as required.
The actual installation of the manual controller was not performed
under the guidelines of A. P.
190.15,
"Plant Changes
and Modifications"
which defines
a plant modification as "any change in the plant systems
which accomplishes
a given function by a new method or which alters
the existing approach to accomplishing the function".
This condition also -represents
a failure to follow established plant
procedures.
This is an item of noncompliance.
The inspector reviewed the RTES for Unit 4 Trip Number T101-392 on
August 5, 1979.
While performing routine testing of the turbine trips
a malfunction occurred in the trip reset lever and a turbine trip was
indicated
as reset
when in fact it was not.
This resulted in a turbine
trip and a reactor trip.
To prevent recurrence of trips due to malfunc-
tions of the reset lever,
a Plant Change/Modification was being processed
for implementation
on both units that would provide the operator with
an indication light showing whether or not a turbine trip was reset.
The inspector had no further comments.
8.
Chemical and Volume Control System
(CVCS) - Holdup Tanks
The inspector reviewed the circumstances
associated
with the various failures
experienced with the CVCS-Holdup Tanks
(HUT).
Although the initiating
events for the various failures have not been the same,
the mode of failure
~r'
process" is representative
of an observed
inadequacy in "the implementation
of administrative or procedural controls..." (dictated primarily by A. P.
190.15, Plant Changes
and Nodifications) and as such should have been
reported to the
NRC as required by Technical Specification 6.9.2.b.3.
~ Thus, unresolved
item 50-250/79-24-02 is upgraded to an item of noncompli-
ance
(50-250/79-26-02).
