,NFORMATION USO 1.0 PURPOSE This procedure provides instructions for the Operation of the ISCO Sample Compositors Model 2710 and Model 3710 and associated equipment.
2.0 PRECAUTIONS 2.1 In the unlikely event the Waste Water Retention Basins (WWRB) becomes contaminated, the composited samples should be handled as radioactive material in accordance with standard Health Physics practices.
2.2 Observe all safety precautions outlined in 30006-C, "Laboratory Safety Manual".
2.3 Do not attempt to retrieve a composite sample while the sampler is in the run mode.
2.4 The sampler is pre-programmed to automatically purge and deliver the proper amount of sample to the sample container. Do not attempt to reprogram the compositor without notifying Laboratory Supervision.
2.5 Sample volume per composite is affected by pressure in the sample line, sample tubing length and pump tubing size. Ensure sample line pressure down stream of the pressure reducing valve remains less than 4 psig. Recalibrate delivering volume following replacement of sample tubing or pump tubing for the ISCO Model 2710 compositor. The ISCO Model 3710 compositor is self calibrating and pump maintenance does not require re-calibration of the sample volume.
2.6 Even if no primary to secondary leak is confirmed, the operation of the compositors is required. The sample should be discarded into the associated WWRB if there is no confirmed primary to secondary leak.
3.0 SYSTEM DESCRIPTION The automatic sample compositors and associated piping are designed to collect composite samples from each of the Waste Water Retention Basins during basin pumping evolutions. Each sampler pumps uniform, small sample increments into its respective container at equal flow volume intervals using flow pulse inputs from an external flow meter. A sample recirculation flowpath is established in the compositor suction piping whenever the WWRB discharge piping is pressurized. This piping arrangement provides a representative sample when the pre-programmed compositing sequence is initiated.
Sample collection may also be manually initiated at any time. (Refer to Figure 1)

Press the "ENTER VALUE" key. Press the "Program/Step Program" key. The "CALIBRATE SAMPLE VOLUME" light will sequence on.
4.4.9 Enter the pre-purge (PO--) volume counts, (UNIT 1 =450, UNIT 2 = 450). Press the "ENTER VALUE" key.
4.4.10 Press the 'PROGRAM/STEP PROGRAM" key, enter the fill cycle (Fl--) volume counts, (UNIT 1 = 550, UNIT 2 =550). Press the 'ENTER VALUE" key.
NOTE These values may be changed as necessary to keep sample volume delivered at or near 100 ml. Notify Laboratory Supervision of any changes.
4.4.11 Press the "PROGRAM/STEP PROGRAM" key, enter post-purge (P1--) volume counts, (Unit 1=450, Unit 2=450). Press the "ENTER VALUE" key.
4.4.12 Press the "PROGRAM/STEP PROGRAM" key, enter zero for the second fill cycle (F2--)
volume count. Press the "ENTER VALUE" key.
4.4.13 Press the "PROGRAM/STEP PROGRAM" key. The NUMBER OF COMPOSITE SAMPLES light will sequence on. Enter the total number of samples to be composited, (UNIT 1 =160, UNIT 2 =160). Press the "ENTER VALUE" key. Press the "PROGRAM/STEP PROGRAM" key to (----) indication.
4.4.14 Press the "START PROGRAM" key to initiate the program sequence. This program is now set such that each 100 counts on the flow integrator (at back of cabinet) causes a composite sample to be collected. This sample is approximately 100 ml in volume. Each count on the flow integrator represents 100 gallons pumped from the WWRB, this means that for every 10,000 gal pumped from the WWRB we obtain a sample.
4.5 SAMPLE DELIVERY VOLUME CALIBRATION FOR THE ISCO MODEL 2710 4.5.1 Initial conditions:
A. WWRB is being discharged (or is on recirculation)
B. Sampling system valves are aligned as shown in Figure 1 C. Pressure regulator 1(2)-PCV-17808 is reading 4 psig or less. Regulator may be adjusted to achieve the desired reading.

4.5.11 Press the "ENTER VALUE" key.
4.5.12 Press the "PROGRAM/PROGRAM STEP" key until four dashes (----) are displayed.
4.5.13 Return to step 4.5.4 to determine the new delivered volume.
4.5.14 When the desired volume has been obtained, re-assemble the compositor and press "START PROGRAM" to re-set the aliquot count to zero.
4.5.15 Complete the calibration certificate and forward to chemistry supervision.
5.0 TROUBLESHOOTING NOTE The following steps should be used as needed, and no sequence is implied.

Discrepancies should be brought to the attention of lab supervision.
5.3 Valve alignment should be checked (Using Figure 1) when routine monitoring indicates no water is entering the compositor.
6.0 MAINTENANCE 6.1 Routine maintenance consists mainly of keeping sample tubing and containers clean and free of debris. Whenever composited samples are recovered a visual inspection of sampler components should be performed.
6.2 Section 3.0 of the Manufacturer's Instruction Manual provides detailed maintenance procedures for the compositors.
6.3 If the ISCO sampler fails and can not be repaired quickly, a spare ISCO Model 2710 sampler is stored in the Demineralizer Building and can be utilized until a repair can be completed.
6.4 Pressure regulator 1(2)-PCV-17808 should be set just below 4 psig when a WWRB pump is running. The regulator can be adjusted with the adjusting screw under the cap.
