1.1 Objective Provide the method for sampling and analyzing Unit 2 reactor coolant and liquid waste during Station Emergency Response Organization (SERO) i 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 t he reactor coolant or liquid waste. The presence and amounts of ccitain radioactive isotopes are indicative of the type (s) and extent of core damage that exists. The results obtained from this Il C' procedure assin the MRDA or AMRDA in determining an estimate of l

Unit 2 core damage. The Unit 2 systems which can be sampled and the l analyses which can be conducted through performance of this procedure are summarized in the following lists:

Systems Analyses Reactor Coolant Liquid Isotopic i Shutdown Cooling Gaseous Isotopic High Pressure Safety injection Gaseous Composition j Low Pressure Safety injection 'Ibtal Dissolved Gas j Liquid Radwaste Chloride j !

Baron pli ;

The time required to collect and analyze core coolant samples is 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months ,

or less from the time the ADTS makes the decision to obtain a sample I using PASS, except for chloride, which is 96 hours0.00111 days 0.0267 hours 1.587302e-4 weeks 3.6528e-5 months . 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 l 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. j i

I This procedure is linked to the Emergency Plan, therefore the Emergency O Planning Services Department will be a cross discipline reviewer for all revisnns or changes to this procedure.[Ref. 6.25] j 1.3 Appil(ability This procedure is applicable during SERO activation when in plant radioactivity levels are too high to permit reactor coolant or liquid waste j sampling via the normal (conventional) method. '

1.4 Frequency Performance of this procedure may be repeated periodically during SERO l 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. Ifinfluent 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 j must be closed at all times except when a syringe is inserted into either i 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 Primaiy 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 i; 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, I O- 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 4 must be directed to the VCT for all other performances of this procedure.

SUMMARY

OF CUANGES l

(

)

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.

l 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.
