Docket Nos.

License
Nos.
During an
NRC inspection
conducted
between
February
19 and April 1,
1995,
several
examples
of a violation of NRC requirements
were identified.
In
accordance
with the "General
Statement of Policy and Procedure
for NRC
Enforcement Actions,"
10 CFR Part 2, Appendix C, the violations are listed
below:
Diablo Canyon Technical Specification 6.8. 1. states,
in part, that
written procedures
shall
be established,
implemented,
and maintained
covering the applicable
procedures
recommended
in Appendix
A of
Regulatory
Guide
1 '3, Revision
2, dated
February
1978.
Appendix
A of Regulatory
Guide 1.33,
Revision
2,
recommends
procedures
covering the operation of emergency
core cooling systems,
surveillance
testing of safety
systems
required Technical Specifications,
chemical
control,
and administrative
procedures
for equipment control.
1.
Revision
10 of Operations
Procedure
(OP) B-3B:I, "Accumulators
Fill and Drain," Step 6.5.6,
requires
operation of Flow Control
Valve
(FCV) FCV-8878B to fill Accumulator 1-2.
Contrary to the above,
on March 22,
1995,
Valve FCV-8876B was
operated
instead of Valve FCV-8878B, resulting in
a partial drain
down of the accumulator.

~
Revision
11A of STP M-16N, "Operations of Trains
A and
B Slave
Relays
K632 and K634," Step
12. 10.3, requires restoration of both
Valves
FCV-37 and
FCV-38 to the open position.
Contrary to the above,
Step
12. 10.3
was incorrectly marked
N/A, on
March 14,
1995, resulting in failure to restore
the valves to
proper position at the conclusion of the surveillance.
Revision
1 of OP 1.DC20,
"Sealed
Components,"
Step 4.2.5,
requires
that Category
1 valve seals
may be broken,
when the checklist is
required to be current,
only after receiving documented
authorization
by the appropriate Shift Foreman.
Contrary to the above,
on March 28,
1995,
the licensee
operated
sealed
Valve SI-2-8920B without documented
authorization
or Shift
Foreman
approval.
Revision
8 of OP C-7C: III, "Condensate
Polishing
System
Transferring
Resin Beds,"
Step 6.4, contains
a manual
valve
alignment
sequence
for transfer of resin
and requires
a 25-minute
drain of the demineralizer prior to proceeding with the manual
transfer
procedure.

Contrary to the above,
on April I, 1995, neither the manual
valve
alignment
sequence
nor the 25-minute drain requirement
were
followed.
The incorrect valve alignment resulted
in
overpressurization
of the resin transfer
system
and rupture of the
anion regeneration
tank.
This is
a Severity
Level
IV violation (Supplement I).
