' ITEM-OF? NONCOMPLIANCE iTechnical. Specification'3.3.7.10 states that the radioactive: liquid monitoring instrumentation channels shown in
. T a b l e. 3.~ 3. 7 ; 1 0 - 1, shall be operable with their alarm / trip setpoints
. set-to_ ensure'that the limits of specification 3.11.1.1 are not
-exceeded.
Action statement 3.3.7.10.a states that with a radioactive
-liquid effluent monitoring instrumentation channel alarm / trip
- setpoint.less conservative than required, immediately suspend the
~
release of radioactive -liquid effluents monitored by the affected channel.or declare..the channel' inoperable.
Contrary to-the above on August 23, 1984, a radioactive liquid effluent release was made from a discharge tank with a nonconservative> alarm / trip setpoint.
CORRECTIVE-ACTION TAKEN-AND' RESULTS ACHIEVED No immediate corrective action was taken, since the error
-was'not recognized until a.second similar occurence on September 27, 1984:was1 discovered;for batch 45-84.
