- 1. PURPOSE 1.1 Objective Provide the method for sampling and analyzing Unit 2 reactor coolant and liquid waste during Station Emergency Response Organization (SERO) activation when high radioactivity levels, due to an accident, may preclude the normal (conventional) sampling method. The sampling and analysis are performed by the Liquid PASS Team as directed by the Manager of Radiological Dose Assessment (MRDA) or the Assistant Manager of Radiological Dose Assessment (AMRDA).
Performance and implementation of this procedure satisfies the Millstone Unit 2 Technical Specification 6.18. 1.2 Discussion This procedure provides instructions used by the Liquid PASS Team for sampling and analysis of reactor coolant, liquid waste, or both, during post accident conditions. The analyses conducted in this procedure identify the presence and amounts of various radioactive isotopes and ionic impurities contained in the reactor coolant or liquid waste. The presence and amounts of certain radioactive isotopes are indicative of the type(s) and extent of core damage that exists. The results obtained from this procedure assist the MRDA or AMRDA in determining an estimate of Unit 2 core damage. The Unit 2 systems which can be sampled and the analyses which can be conducted through performance of this procedure are summarized in the following lists: Systems Analyses Reactor Coolant Liquid Isotopic Shutdown Cooling Gaseous Isotopic High Pressure Safety Injection Gaseous Composition Low Pressure Safety Injection Total Dissolved Gas Liquid Radwaste Chloride Boron pH The time required to collect and analyze core coolant samples is 3 hours or less from the time the ADTS makes the decision to obtain a sample using PASS, except for chloride, which is 96 hours. Gross activity is the sum of liquid and gaseous isotopic activity. In the event of a SIAS accident the following valves 2-RC-001, 2-RC-003 and 2-RC-045 will automatically close. If this occurs they will have to be manually over-ridden to open. This action will require SM/US direction and concurrence. These valves are over-ridden by taking them to the closed position and then to the open position.

This procedure is linked to the Emergency Plan, therefore the Emergency Planning Services Department will be a cross discipline reviewer for all revisions or changes to this procedure.[Ref. 6.25] 1.3 Applicability This procedure is applicable during SERO activation when in-plant radioactivity levels are too high to permit reactor coolant or liquid waste 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 AMRDA for updates or reassessments of Unit 2 reactor coolant or liquid waste PASS results.

- 3. PRECAUTIONS 3.1 Do not exceed 165°F influent sample flow temperature to the sample module. If influent sample flow temperature exceeds 165°F, secure sample flow to prevent damage to the sample module.
3.2 Do not exceed 2500 psig system pressure because this may damage reactor coolant PASS components. 3.3 Do not run stripping pump dry for longer than 5 minutes because this may damage the pump. 3.4 Valves 2-S-492 (V-9) and 2-S-496 (V-14) in the sample module must be closed at all times except when a syringe is inserted into either sample chamber (liquid or gas) for sample retrieval. Failure to do so may discharge radioactive reactor coolant from the sample module into the Unit 2 Primary Sample Sink Room. 3.5 Valve 2-S-499 (V- 18) on the remote operating module must always be in the low flow position when system pressure is greater than 415 psia to prevent high pressure spikes due to water hammer.

3.6 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 AMRDA for further instructions. 3.7 The maximum design pressure for the pH probe is 250 psig. Do not exceed 250 psig at pH probe. 3.8 PASS sample effluent may be sent to radwaste (EDST) when this procedure is performed as part of a PASS drill or exercise. PASS effluent must be directed to the VCT for all other performances of this procedure.
/3.9 2-RB-210, Degassifier Effluent Cooler Return Isolation Valve Assembly, needs to be open during sampling to prevent exceeding temperature limits of the equipment. It should not be open for extended periods of time as cooling will be diverted from other components when this valve is open.

SUMMARY
OF CHANGES 7.1 Added amplifying wording as to when 2-RB-210 is to be opened. 7.2 Added specific instructions as to when to open and close 2-RB-210. 7.3 Added alternate total purge volumes based on analysis required as part of sampling. 7.4 Changed initial purge volume due to increasing volumes purged through lines prior to isolating in-line samples. 7.5 Increased line purge volumes to ensure lines are sufficiently flushed prior to isolating sample. 7.6 Deleted requirement for Health Physics to monitor radiation levels on contact with sample just prior to analysis. This monitoring is performed as sample is acquired both utilizing RMS-2 data and also as samples are physically retrieved at the Primary Sample Module. Summary of Changes Rev. 003-01 7.7 Editorial Correction; Updated Reference 6.17 NRC commitment letter.

- 1. PURPOSE 1.1 Objective Provide method for sample collection and analysis of Unit 2 Vent, U2 releases to Main Station Stack and containment atmosphere via PASS when radioactivity levels may preclude the use or the normal sampling method. Sampling and analysis will be directed by the MRDA or AMRDA during an event which activates the Station Emergency Response Organization (SERO).
1.2 Discussion This procedure provides the instructions used by chemistry for sampling and analyzing containment atmosphere and ventilation atmosphere during post accident conditions. The analysis conducted in this procedure identify the presence and amounts of various radioactive isotopes contained in the ventilation or containment air. The presence and amount of certain radioactive isotopes are indicative of the type(s) and extent of core damage that exists. The results obtained from this procedure assist the MRDA or the AMRDA in determining an estimate of Unit 2 core damage. Samples (excluding ventilation) must be obtained and analyzed within 3 hours of the time the decision was made to obtain the sample. Additionally gas composition of CTMT air is possible, the limiting factor in analysis of these samples will be gas composition analysis. The gas chromatograph may take up to an hour to replumb. If time allows, replumbing gas chromatograph (GC) for PASS analysis is made prior to sample collection. 1.3 Applicability This procedure is applicable during SERO activation 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.

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:
Total Activity on Normal Counting Shelf (step #6) Shelf Ratio = Total Activity on Elevated Shelf (step #3) CP2804M Level of Use Rev. 001-01 TH1,N, ACT Continuous 78 of 79
