4.0 PRECAUTIONS AND LIMITS: (continued) 4.3 Evaporated or high activity particulate, samples being counted on a gas flow counter should not be exposed to Gas Medium - Purge flow prior to the count.

The surge of this counting gas may blow bits of the sample all over the counting chamber, rendering the chamber in continuous discharge by electrical short or will contaminate the chamber for the next sample count. Just use regular bubble rates, but allow the sample to count for 5 - 10 minutes prior to restarting the official count. If it is an effluent sample, two consecutive sample counts within + 10% should be observed prior to documenting the official results.

4.4 All Tritium (H-3) samples should be degassed. These samples should not be thrown away. Save the cocktail vials for possible recount since it may be difficult to remove the dissolved gases, even with air sparging or boiling. Very small volumes (100 lambda) should be used to avoid any Dead Time on counting devices.

4.5 Unless samples are actually being counted or prepared, they should be stored in a building away from the counting building. Noble gas diffusion off of some samples could affect other low level sample results.

4.6 The calculations and'sample parameter entries into computer based systems should be verified by a second checker to eliminate human fatigue errors in the results.

4.7 Unless the sample is an effluent release sample, no Minimum Detectable Activity (MDA) or Lower Limit of Detection (LLD) limits shall apply. For effluent release samples the Chemistry Supervisor may authorize deletion of MDA requirements in the early phases (days) of the accident to speed sample results that have a bearing on maintaining control of the accident situation.

4.8 Special precautions may be implemented to ensure the gamma counting shelves and detectors do not become contaminated. Thin poly bags, tape etc.

may be used to protect the detectors and counting shelf apparatus. This should not affect the results because it is only doubling the thickness of normal containment procedures.

Page 3 of 10 ST. LUCIE PLANT CHEMISTRY PROCEDURE NO. C-111, REVISION 8 ESTABLISHING REMOTE ANALYSIS LABORATORY COUNTING LABORATORY AND COUNTING PROCEDURES FOR ACCIDENT SAMPLES 4.0 PRECAUTIONS AND LIMITS: (continued) 4.9 A table indicating the maximum gross counts versus sample container for a specific counting device should be prepared and posted near the gross count monitor (or a frisker) This device may be used as a screening count to guard

~

against excessive DEAD TIME occurring on a particular counting device. The table should be used when counting samples that have not been screened.

Table. 4.9 (attachment) can be filled in as needed. Since Gamma Radiation will be-present in just about every sample, the method can be used on all types of samples except when a chemical separation or a distillation has been performed such as Strontium or Tritium. Initial H-3 samples should be counted in two different volumes (0.1 milliliter (ml) and 1 ml) and agreement should be observed. Strontium filters should be checked by holding a frisker over the precipitate prior to counting the sample in a gas flow device.

4.10 If the remote laboratory is set up outside the Reactor Auxiliary Building (RAB),

the sample and sample waste water shall be contained to prevent contamination of CL'EAN drains and systems.

8.0 INSTRUCTIONS

The decision to establish the remote labs and their. location are made in C-110 Collecting Initial Set of Post Accident Samples. During the first hours following an accident, the primary concern should be getting a Boron stand and a Germanium Lithium (GeLi) Detector set up for counting the samples called for in C-110 above.

The topics and their applicable sections are given below. They are listed in order of importance. in which to set up first:

ORDER 8. TOPIC SECTION REMARKS 1ST Boron Test Stand Set up 8.1 As soon as possible 2ND Initial GeLi Set up 8.2 As soon as possible 3RD Back up GeLi Set Up 8.3 as time permits 4TH Tritium Counter 8.4 as time permits 5TH Gas Flow Counter 8.5 as time permits 6TH Gross Monitor Nal Bench Top 8.6 as time permits Section 8.7 describes general operating procedures for the Counting Lab. It may not be possible to set up each device in the same area due to size of equipment and possible radiation levels of the samples. In this case locate the equipment in the best operating environment possible at a.location where one or two people can keep up with changing samples.

8.1 The Boron Analysis equipment setup and calibration check are described in C-35 and Appendix A of C-35, "Determination of Boron," and in COP-07.03, "Determination of Boron Using the Orion FASTQC Titrator." /R8 8.2 The initial set up of the 1ST GeLi System requires the following:

A. A NIM BIN with Analog to Digital Converter, 1 Amplifier (AMP), 1 High Voltage Power Supply and 1 Liquid Nitrogen Level Monitor (optional) or ortec equivalent 92X box.

B. Gamma Spectrum Analyzer System C. A GeLi Detector with Dewar (associated Dewar scale is optional).

8.0 INSTRUCTIONS

(continued) 8.6 (continued)

3. Return the Function Switch to Operate.

4. Take a known source of radioactivity and see that the radiometer responds upscale when the source is placed on the detector.

5. This monitor can be used to screen samples prior to counting on the PHA or for quick checks on relative gross activity of samples.

6. This monitor should be added to the daily functional check surveillance and verified operable with a button source.

1 8.7 Special Counting Techniques for Accident Samples:

1. Check the gross count rate of the sample on the screening counter (See Precaution 4.9) and compare it to the maximum counts per minute (cpm) limit on Table 4.9 posted nearby.

2. If the cpm are greater than the maximum, the sample is too hot to count on the specific device. Use an acceptable method to reduce the volume of the sample in the counting container. If the cpm are below the posted limit, the sample can be counted on the device without concern for excessive Dead Time.

3. Make sure the sample is in a plastic bag or glove finger prior to mounting it.

4. Remove hot samples from the counting area as soon as possible.

5. Observe Detector Background counts on a periodic frequency several times per day. If a sample from a stream indicates hot when no activity had been detected before, check for a contaminated detector.

6. Follow the instructions of the appropriate Chemistry Procedure for operating instructions on each device.
