Report 50-387/85-16;
50-388/85-15 (4/22/85',-
5/8/85)
'I
This inspection
reviewed the circumstances
which led to the inoperability,
identified by your personnel,
of one loop of Emergency Service Water
(ESW) and
Residual
Heat
Removal
(RHRSW) during the period April 4 -".April
21,
1985.
During this period Unit 2 was in Operational
Condition
1 andIwas
required
by your Technical Specifications
to have
two independent
loops of ESW/RHRSW.
This condition was caused
by sliding links ("States" links) that were left open
during modification work performed
as part of, the Unit
1" Refueling Outage.
This condition existed for approximately four weeks,
although anomalies Iwere
observed
by the control
room operators
during the period.
We are concer'ned
that these
anomalies
were not aggressively
pursued
and that additional sliding
links were found to be
open in various
systems
in the plant.
This event
has
revealed
a need for increased
sensitivity to the broader
consequences
of
individual equipment anomalies,
particularly as it applies to the operability
of systems
and components
common to both units,
and for the strengthening
of
administrative controls.
Since this problem is, in our view, considered
to be serious,
we need
to',
schedule
an enforcement
conference
with you in the
NRC Region I office to
discuss
the underlying reasons
for this matter.
Please
be prepared
to diiscuss
plant modification work controls, post-modification testing, sliding link/
jumpers/bypass
controls,
drawing controls,
and Work Author'ization processing
procedures
which may have contributed to this event.
You should also
beI
prepared
to discuss
the corrective actions you have taken or plan to take.
