60 61 DOCKET NUMBER 68 69 EVENT DATE 74 75 REPORT DATE 80 EVENT DESCRIPTION AND PROBABLE CONSEQUENCES h [o"TT1 1 On October 17, 1982, during a routine containment purge, the Control Room Operator l

[o g3; l observed an abnormal decrease of radioactivity levels indicated by the Containment-l l o l 4 l l ')lant Vent Monitor.

Investigation revealed that the Air Particulate Detector (APD) l loIs1 I sample line to the plant vent had been erroneously capped during partial completion ofl I O l6 l l Design Change Request (DCR) ED-0014.

Subsequent investigation showed the vacuum relief l o l 7 l l device on the suction of the APD was lifting at normal operating pressure in the l

i o ;a ; ; suction line, and the monitor had been inoperable since prior to the unit start-up in l o April of g yyear.
