1. PURPOSE1.1 Objective Provide method for sample collection and analysis of Unit 2 Vent, U2releases to Main Station Stack and containment atmosphere via PASSfollowing an accident as a contingency plan, when radioactivity levels maypreclude the use or the normal sampling method. Sampling and analysis

[can be directed by the MRDA or AMRDA during an event which hasactivated the Station Emergency Response Organization (SERO).1.2 Discussion This procedure provides instructions which may be utilized by chemistry when collecting and analyzing highly radioactive containment atmosphere and ventilation samples and during post accident conditions.

The analysesconducted in this procedure can identify and quantify radioactive isotopescontained in the ventilation or containment air. The presence and amountof hydrogen and certain radioactive isotopes may assist in determining thetype and extent of core damage.1.3 Applicability This procedure is applicable following an accident when in-plantradiation levels may be too high to permit ventilation and containment airsampling via the normal method.1.4 Frequency Performance of this procedure may be repeated periodically during SEROactivation, when requested by the MRDA or AMRDA for updates orreassessments of containment conditions.

2. PREREOUISITES 2.1 General2.1.1 Silver Zeolite Cartridges are used for iodine ventilation sampling1 in conjunction with this procedure (unless otherwise directed by IChemistry Supervision).[4.Ref 6.15]2.1.2 Performance of this procedure must be authorized by the ADTSwhen SERO is activated 2.1.3 When SERO activated assessment by the MRCA for personnel exposure has been performed against station and Federal limits.Level of Use ,CP2804MContinuous

Estimation of core damage may require a largersample aliquot.

If a larger sample is requested by the MRDA orAMRDA, substitute the required size syringes for those stated inthis procedure.

3. PRECAUTIONS 3.1 When locking air samples within syringes, do not rotate syringe more thantwo turns. Excessive turns will disengage needle from syringe resulting inthe possible release of radioactive gasses.3.2 In the event of unexpected results during the course of this procedure, place the equipment in a safe or stable condition, cease performance offurther steps, and contact the MRDA or the AMVRDA for furtherinstructions.

3.3 Silver Zeolite cartridges are hazardous material.
