License
Nos.
52 and 68
The following violations
were identified during
an
inspection
conducted
on
January
26 - February
25,
1985.
The Severity Levels were assigned
in accordance
with the
NRC Enforcement Policy (10 -CFR Part 2, Appendix C).
Technical Specification 6.3.A requires
that detailed written procedures,
including applicable
check-off lists,
shall
be
prepared,
approved
and
adhered to for operations
and surveillance
requirements.
Contrary to the above, this requirement
was not met in that the Surveillance
Instruction 4.2. F.18 ("Main Steam Relief Valve Thermocouple
and Acoustic
Flow Monitor") did not include appropriate
acceptance criteria to ascertain
whether
the
recorded
values
met the "consistency
and nominally expected
value" criteria.
Contrary to the
above;
the requirement
was not met in that the required
. position of dampers
0-30-503,
504,
505
and
506 in the valve checklist
contained
in Operating Instruction
30 "Ventilation System"
was ambiguously
~
stated
("OPEN
TO
PRESET
POSITION" )
such that operators
were
unable- to
'etermine
the correct required position.
This was
a contributing cause to a
misalignment event, on January
14,
1985 which resulted
in airborne
radioactivity in the
radwaste
building in excess
of 10 CFR 20
maximum
permissible concentration
(Xe 135).
This.'is
a Severity Level
V violation (Supplement I) applicable to all units.

steps
which have

steps
which will be taken to avoid
further violations
and (5) the date
