1. PURPOSE 1.1 Objective 1.2 Provide method for sample collection and analysis of Unit 2 Vent, U2 releases to Main Station Stack and containment atmosphere via PASS following an accident as a contingency plan, when radioactivity levels may preclude the use or the normal sampling method. Sampling and analysis can be directed by the MRDA or AMRDA during an event which has activated the Station Emergency Response Organization (SERO).

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 analyses conducted in this procedure can identify and quantify radioactive isotopes contained in the ventilation or containment air. The presence and amount of hydrogen and certain radioactive isotopes may assist in determining the type and extent of core damage.

1.3 Applicability This procedure is applicable following an accident when in-plant radiation levels may be too high to permit ventilation and containment air sampling via the normal method.

1.4 Frequency Performance of this procedure may be repeated periodically during SERO activation, when requested by the MRDA or AMRDA for updates or reassessments of containment conditions.

2. PREREOUISITES 2.1 General 2.1.1 Silver Zeolite Cartridges are used for iodine ventilation sampling1 in conjunction with this procedure (unless otherwise directed by Chemistry Supervision).[4.Ref 6.15]

I 2.1.2 Performance of this procedure must be authorized by the ADTS when SERO is activated 2.1.3 When SERO activated assessment by the MRCA for personnel exposure has been performed against station and Federal limits.

2.1.4 The sample aliquots listed in this procedure are not fixed numbers. Estimation of core damage may require a larger sample aliquot. If a larger sample is requested by the MRDA or AMRDA, substitute the required size syringes for those stated in this procedure.

3. PRECAUTIONS 3.1 When locking air samples within syringes, do not rotate syringe more than two turns. Excessive turns will disengage needle from syringe resulting in the 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 of further steps, and contact the MRDA or the AMVRDA for further instructions.

3.3 Silver Zeolite cartridges are hazardous material. These cartridges must be collected and transferred to Waste Services Department for proper disposal.

Attachment 4 Shelf Ratio Calculation (Sheet 1 of 1)

In the event that a detector shelf extension tube was required during operation of the Computer Radioisotopic Analysis System, the appropriate shelf ratio must be determined for use in activity level correction calculations. To determine the shelf ratio, perform the following steps upon completion of the isotopic analysis:

1. REMOVE sample from gamma spectrometer.

2. PLACE a calibration source on the same detector shelf extension tube which was used for analysis of the sample.

3. COUNT calibration source using the following information:

Count time: Same as sample's count time

Volume: 1

Geometry: Particulate filter

4. Upon completion of count, REMOVE detector shelf extension tube.

5. PLACE calibration source on normal counting shelf.

6. With cave door open, COUNT calibration source using the information provided in step 3.

NOTE Shelf ratio should be calculated to two significant digits only.

7. CALCULATE shelf ratio using the following equation and the activity levels obtained in steps 3 and 6:

TotalActivity on Normal Counting Shelf (step #6)

ShelIf Ratio =

TotalActivity on Elevated Shelf (step #3)
