- 1. PURPOSE 1.1 Objective Provide instructions for operation of the Unit 3 containment air post accident sample system for containment air sample acquisition when high i radioactivity levels, may preclude the normal (conventional) sampling method.
This procedure satisfies regulatory commitment B 18443-01 to maintain contingency plans for obtaining and analyzing highly radioactive samples of the containment atmosphere.
This procedure was developed using the reactor technical manual for the containment air PASS (Ref.6.2) and other documents identified herein. I 1.2 Discussion If conditions arise that will not allow Sections 4.1 through 4.4 to be completed, the procedure user will be directed to Section 4.8, "Restoration from PASS Sample Acquisition," to return the system to normal.
Attachment 4 contains a simplified drawing of the containment air post accident sample system. I i
1.3 Applicability This procedure is applicable when in-plant radioactivity levels are too i high to permit containment air sampling via the normal (conventional) -@
method.
1.4 Frequency As required during periods of elevated in-plant levels. E

- 1. PURPOSE 1.1 Objective Provide instructions for operation of the Unit 3 containment air post accident sample system for containment air sample acquisition when high i radioactivity levels, may preclude the normal (conventional) sampling method.
This procedure satisfies regulatory commitment B 18443-01 to maintain contingency plans for obtaining and analyzing highly radioactive samples of the containment atmosphere.
This procedure was developed using the reactor technical manual for the containment air PASS (Ref.6.2) and other documents identified herein. I 1.2 Discussion If conditions arise that will not allow Sections 4.1 through 4.4 to be completed, the procedure user will be directed to Section 4.8, "Restoration from PASS Sample Acquisition," to return the system to normal.
Attachment 4 contains a simplified drawing of the containment air post accident sample system. I i
1.3 Applicability This procedure is applicable when in-plant radioactivity levels are too i high to permit containment air sampling via the normal (conventional) -@
method.
1.4 Frequency As required during periods of elevated in-plant levels. E
