1. PURPOSE1.1 Objective Provide instructions for operation of the Unit 3 containment air postaccident sample system for containment air sample acquisition when high iradioactivity levels, may preclude the normal (conventional) samplingmethod.This procedure satisfies regulatory commitment B 18443-01 to maintaincontingency plans for obtaining and analyzing highly radioactive samplesof the containment atmosphere.

This procedure was developed using the reactor technical manual for thecontainment air PASS (Ref.6.2) and other documents identified herein. I1.2 Discussion If conditions arise that will not allow Sections 4.1 through 4.4 to becompleted, the procedure user will be directed to Section 4.8,"Restoration from PASS Sample Acquisition,"

to return the system tonormal.Attachment 4 contains a simplified drawing of the containment air post iaccident sample system. I1.3 Applicability This procedure is applicable when in-plant radioactivity levels are too ihigh to permit containment air sampling via the normal (conventional)
