On April 22
May 8,
1985,
an
NRC inspection
was conducted to review the circum-
stances
associated
with a violation of'a technical
specification limiting
condition for operation
(LCO).
The violation, which was identified by the
licensee
and reported to the
NRC, involved the inoperability of one loop of the
Emergency
Service
Water
(ESW) system,
which is common to both Units
1 and 2, for
approximately
17 days in excess
of the
LCO action statement.
The
ESM loop was
in that
a valve required for loop operation
would not open automatically
if needed.
The capability to manually operate
the valve existed throughout the
period.
Further,
the redundant
loop was operable.
One other violation ~of NRC
requirements
regarding
survei llances
on both loops was also identified by the
licensee.
In accordance
with the General
Statement
of Policy and Procedure for NRC
Enforcement Actions,
10 CFR Part 2, Appendix
C (1985),
the violations are set
forth below:
A.
Technical Specification Limiting Condition for Operation
( LCO) 3.7.'1.2
for Unit 2 requires that during all operational
conditions,
two independent
Emergency
Service Mater
(ESW) system
loops shall
be operable with each
loop
comprised of two operable
ESW pumps
and
an operable
flow path capable of
taking a.suction
from the spray
pond and transferring the water to 'the
associated
safety-related
equipment.
With one
ESW loop inoperable,~~ in
Operational
Condition 1,
2 or 3, the loop is to be restored
to an operable
status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or the plant is to be in hot shutdown within,'he
next
12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
Contrary to the above,
from approximately
5: 14 p.m.
on April 4,
1985,
until 5:00 a.m.
on April 21,
1985, while Unit 2 was in Operational
Condition 1, the 'A'oop of
ESW was inoperable
in that the Spray
Pond
Bypass Valve, required to be
open for loop operation,
was closed
and not
capable of being automatically
opened
because
of an isolated
power supply.
This is
a Severity
Level IV violation (Supplement I).

Appendix

Contrary to the above,
2
B.
Unit 2 Technical Specifications
require that periodic surveillancebe
performed
on the
ESW system.
Specifically, Technical Specification 4.7.1.2
requires
performance of a valve alignment for the
ESW system every i31 days.
Technical Specification 4.0.5 requires
performance
of quarterly
pump flow
tests
and valve exercising tests for pumps
and valves in the
ESW system.
Technical Specification 4.0.2 permits these .surveillance intervals~to
be
exceeded
by up to 25 percent.
A valve alignment of the
ESW system
was not performed
between
'arch
17 and April 25,
1985,
a period of 39 days,
which exceeds
the
allowable surveillance interval of 31 days
by more than
25 percent.
b.
The
pump flow tests for pumps in the
ESW system were not performed
between
December
31,
1984
and April 25,
1985,
a period exceeding
the
allowable quarterly surveillance interval
by more than
25 percent.
c.
The valve exercising tests for valves in the
ESW system were n'ot
pe~formed
between
January
1,
1985 and April 25,
1985,
a period ex-
ceeding
the allowable quarterly surveillance
interval
by more 'than
25
pe~cent.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201,
Power and Light,
Company is hereby required to submit to this office, within thirty days of the
date of the letter which transmitted this Notice,
a written statement
or~,
explanation
in reply, including: (1) the corrective steps
which have
been
taken
and the results

(2) corrective steps
which will be taken to avoid
further violations;
and (3) the date
when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending
