1. s PURPOSE

'1.1 - Objective Provide instructions for operation of the Unit 3 containment air post -1 accident sampling system for' containment air sample acquisition during i Station Emergency Response Organization (SERO) activation when high radioactivity levels, due to an accident, may preclude the normal 1 (conventional)' sampling method. 3 This procedure satisfies requirements listed in Unit 3 Technical l Specification 6.8.4 d.

1 1.2 Discussion l

_ The time required to collect and analyze samples should be 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> or less '

- from the time the ADTS makes the decision to obtain a sample using PASS.

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 systen. .a '

normal.

! '1.3 Applicability This procedure is applicable during SERO activation when in-plant  !

radioactivity levels are too high to permit containment air sampling via the normal (conventional) method.

1.4 ' Frequency

- Performance of this procedure may be repeated periodically during SERO activation.
