1. E.URPOSE 1.1 Objective Provide instructions for sample acquisition and analysis from the Unit 3 ventilation system during Station Emergency Response Organization (SERO) activation when high radioactivity levels, due to an accident, may preclude the normal (conventional) sampling method.

This procedure partially satisfies the requirements listed in Unit 3 Technical Specification 6.8.4 d. 1.2 Discussion During implementation of the Emergency P!anorganization the r Amistant Director, Emergency Operations Facility (ADEOF) is responsib!e for providing command and centro! cf the radic!cgical ame= ment of the event. "/ hen Unit 3 venti! tion samples ere desired, the ADEOF-directs the Manager of Radic!cgical-Dese Assessment-(MRDA) l l cr the Amistant Manager of Radic!cgica! Dese Assessment (AMRDA) to initiate mp!: acquisition-using this precedure. The Manager-ef Operationa! Support Center (MOSC) designates, assembles, and briefs the-Ventilation-PASS-Team 4er-implementationef-this-procedure,-The Operation:! Support Center Amistart Radic!cgical-Fretection Supervisor g (OSC ARPS)-ith the concurrence bf the Manager of Radic!cgical Consequence Assessment (MRCA) specifies the radic!cgicai-controls required for implementation of this precedure. The Manager of Centrol Room Operations (MCRO) performs er directs valve !!neups from the Centro! Room required 4or-ventilation system 4 ample-acquisition 4nd retrieva! cf samples. Once camp!es are obtained, radie!cgical analysis-are performed on site. Information derived from these samples is used-to estimate core damage and to support dose amemment projections. l The time required to collect and analyze samples should be 3 hours or less from the time the ADTS makes the decision to obtain a sample using PASS. i 1 l Sections 4.1,4.2, and 4.3 are distinct sections that may be performed independently of each other. Section 4.4 is completed following completion of Sections 4.1,4.2, or 4.3. l l Sections 4.5,4.6,4.7,4.8, and 4.9 are distinct sections that may be performed independently of each other. Section 4.10 is completed following completion of Sections 4.5,4.6,4.7,4.8, or 4.9. CP 3804M Level of Use .STOP THINK ACT REVIEW Rev. O Chg.1 Continuous l i 3 of 62 t i i

~ 1.3 Applicability ()- This procedure is' applicable during SERO activation when in-plant radioactivity levels are too high to permit ventilation sampling via the normal (conventional) method. 1.4 Frequency Performance of this procedure may be repeated periodically during SERO activation, when requested by the MRDA or the AMRDA.
