3 GUIDELINES FOR COLLECTING POST ACCIDENT 42 of 82 PROCEDURE NO.: SAMPLES COP-06.06 ST. LUCIE PLANT APPENDIX F CONTINGENCY PLAN FOR POST-ACCIDENT HIGH ACTIVITY SAMPLES (Page 1 of 6)

1. Discussion Per NRC Safety Evaluation and technical specification improvement announced in Federal Register, Vol. 65, No. 211, on October 31, 2000, as part of the Consolidated Line Item Improvement Process (CLIIP), NRC approved Industry /

Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-366, and FPL letters L-2000-131 and L-2001-047, St.

Lucie Plant has developed contingency plans to obtain and analyze highly radioactive post-accident samples from the reactor coolant system, containment sump, and containment atmosphere. This appendix provides guidance for obtaining and analyzing such samples.

2. Applicability For Contingency Plan This contingency plan should be used following a plant event where it is expected that significant core damage resulted. This event would likely have resulted in implementation of the St. Lucie Plant Radiological Emergency Plan (Emergency Plan). The contingency plan actions do not supercede any actions or activities performed in accordance with the Emergency Plan or plant procedures.

The decision to perform any steps in this appendix are at the discretion of the Emergency Coordinator, Recovery Manager, or manager responsible for plant specific activities.

There is no minimum time limit applicable to the performance of steps in this appendix. Considerations for the necessity to perform post-accident sampling, planning or resource procurement time, obtaining vendor support, and dose rate reductions from radioisotope decay may indefinitely postpone or cancel the decision to perform sampling.

Personnel emergency exposure guidelines should be reviewed prior to any decision to perform guidance per this appendix.

3. Considerations For The Performance Of Contingency Plan The actual value to be gained from obtaining highly radioactive post-accident samples should be determined (or weighed) prior to initiating sample activities per this appendix. The following considerations should be reviewed and approved by the Emergency Coordinator, Recovery Manager, or manager responsible for plant specific activities prior to the initiation of sampling:

A. Consider alternate established means to obtain necessary information, such as core damage assessment emergency plan implementing procedure, dose rate correlation calculations, or similarity to historical event results (e.g. TMI).

B. Consider the timeliness of sample information in relation to the expected onset of recovery related activities. For instance, if RCS clean-up activities are not scheduled to start, or do not need to be started, for some time, then additional decay time for radioisotopes could be allowed before planned sampling.

C. Consider the information gained from performing other activities, such as how RCS clean up impacts CVCS filters and resin beds, post-accident containment entries, or verification of estimated core damage from other means. If scope or activities will not change significantly with or without sampling, then consider postponing sampling.

D. Consider the need or expectation to resample at a later time. If it is likely that later samples will also be taken, then consider postponing earlier sample to preserve personnel dose, resources, and equipment.

4. Post-Accident Liquid Sample Contingency Plan Guidelines It is likely that a core damage accident will result in the initiation of Containment Spray, HPSI, SIT and LPSI. After the RWT level has decreased to a specified level, valves will re-align to recirculate the borated water in the containment sump through the core via LPSI pumps. After long-term recirculation, it can be assumed that the radioisotope concentrations in the RCS and Containment Sump will be approximately the same. In this scenario, an RCS Hot Leg sample taken from the Normal Primary Sample System will be representative of activity in the Containment Sump.

Sample locations to determine or estimate Containment Sump conditions in order of preference include RCS Hot Leg and LPSI pump discharge.

The following are guidelines / considerations / recommendations applicable to sampling RCS Hot Leg or LPSI pump discharge.

A. Prior to valve line up for the sample, estimate dose rate effects based on estimated core damage assessment or other means. Include affects on airborne dose rates from sample valve venting.

B. Move portable shield racks and shielding around sample area and associated piping in the sample room, if applicable. Consider additional shielding around sample collection container in sink, if appropriate. Refer to Appendix K, "Shielding Layout" for examples for positioning portable shield racks.

C. Review activities, both current and planned, for potentially affected areas in sample flowpath. Include impact on Volume Control Tank and Liquid Waste System for small addition(s) of highly radioactive liquid.

D. Coordinate sample reentry activities with HP, Operations, and other applicable departments. Ensure that extremity TLDs, emergency exposure authorizations, and contingency radiological plans are reviewed in detail with sample reentry team(s).

E. Consider sample mock-up practices on unaffected unit to improve sample activity efficiency and team response.

Post-Accident Liquid Sample Contingency Plan Guidelines (continued)

F. Determine dilution volumes, counting geometry, and analysis methodology.

Compare to the instructions in Appendices D, E, G and H of this procedure and change, review, and approve as necessary in accordance with plant procedures.

G. Provide the shortest possible transfer time from sink to dilution container.

Place dilution container with proper water dilution volume, and (sample pipette device) in sample room. Consider placing shielding around sample beaker and dilution container.

H. Consider obtaining and storing an undiluted sample (per Appendix I or J) for later analysis by FPL or other vendor / agency.

1. Store diluted samples behind shielding or in a lead storage locker whenever analyses are not in progress.

J. Determine if support or resources from Turkey Point are necessary or available.

K. Determine if additional vendor support is warranted. Procure vendor services in accordance with plant procedures. Use INPO member plant resources agreement, as appropriate, to expedite resource procurement.

L. Once all departments and reentry team(s) are prepared and briefed, initiate valve line up and sampling in accordance with Appendix D, E, G or H.

M. Following sampling and analysis, provide results to Emergency Coordinator, Recovery Manager and / or specific responsible manager.

Local grab samples for Hydrogen concentration and / or isotopic analysis can be obtained from the Containment Hydrogen Analyzers in accordance with 1-COP-06.03 & 2-COP-06.04. The Grab Sample Carts, with sample bombs, are shielded and considerations for high activity samples have been reviewed for this system.

Guidelines for obtaining grab samples from the Containment Hydrogen Analyzers.

A. Review 1-COP-06.03 [2-COP-06.04] for obtaining and analyzing a containment atmosphere sample.

B. Venting evolutions at the Local Grab Sample station and in the lab may cause applicable effluent monitor to go into an ALERT Alarm. Exercise caution to ensure a HIGH Alarm is NOT reached.

C. Determine if any changes to procedures should be made as a result of specific plant conditions, unexpected dose rates, etc. Perform procedure changes in accordance with plant procedures.

D. Coordinate sample reentry activities with HP, Operations, and other applicable departments. Ensure that extremity TLDs, emergency exposure authorizations, and contingency radiological plans are reviewed in detail with sample reentry team(s).

E. Consider sample mock-up practices on unaffected unit to improve sample activity efficiency and team response.

F. If analysis of an undiluted sample is not immediate, store sample in a area determined by HP until analysis is performed.

G. Determine if support or resources from Turkey Point are necessary or available.

LUCIE PLANT APPENDIX J OBTAINING A UNIT 2 POST ACCIDENT UNDILUTED RCS SAMPLE FROM THE NORMAL PRIMARY SAMPLE SYSTEM (Page 1 of 9) 1.0 PURPOSE To provide instructions for obtaining a Unit 2 undiluted RCS sample from the Normal Primary Sample System during the recovery phase of an accident (post accident) in conjunction with Appendix F.

2.0 PREREQUISITES

1. Component Cooling Water (CCW) shall be supplying cooling water to the sample heat exchangers.

2. Normal Primary Sample System must be operational.

3. The Primary Sample Fume Hood Ventilation must be operational. If fume hood ventilation is not operable, unacceptable levels of noble gases will be present in the sample sink and adjacent area.

4. Health Physics shall issue a specific RWP and provide HP coverage during recovery phase RCS sampling evolutions.

3.0 PRECAUTIONS / LIMITATIONS

1. It is preferable to recirculate / flush samples back to the VCT. The Flash Tank is the second choice. The flow path shall be determined and discussed during the pre-job brief.

2. The Control Room must be notified prior to recirculating or flushing samples to the Flash Tank.

3. If a CIS has occurred, the solenoid valves to sample the RCS (V5200 &

V5203) can not be opened until the Control Room overrides the CIS signal and the valves are RESET.

4. DO NOT apply system pressure to the Hot Leg sample line without the Undiluted Sample Cask installed.

5. ¶i Solenoid valves for the Hot Leg sample line should be closed after sampling.

6. Minimize contact with reactor coolant samples.

7. Temperature of the samples should be less than 120 degrees F.
