+12. 10. 3 DETERMINATION OF CHLORIDES 12.10.3.1 P~uz oee This procedure describes a method of determining low level chloride con-centrations on post accident liquid sample diluted 1 ml to 10 ml final volume.

12.10.3. 2 Precautions/Prere uisites A. Analysis are to be performed when conditions are Al ARA.

B. Direct waste lines from the ion chromatograph to shielded con-tainer in a hood.

C. Dionex System 2 valves must be toggled to:

1. Separator 2
2. Suppressor 2 Eluent 2 D. Dionex System 2 flow rate should be approximately 3.0 mls/min.

E. HP 3390 Integrator Settings

12.10.3.3 R~ea enta (Prepare when required)

A. Eluent 2 0.0015 M NaHC03 Dissolve 0.5040 gms NaHC03 in one liter demineralized water then dilute to 4 liters. Label as per PPM 12.2.6.4.

B. Regeneration Solution 1N H2S04 to approximately 800 mls of demineralized water add slowly ill mls concentrated sulfuric acid.

Allow to cool to room temperature then dilute to 4 liters. Label as per PPM 12.2.6.4.

C. Chloride Standard - 10 ppb From a stock 1000 ppm standard dilute serially to 10 ppb. Label as per 12.2.6.4.

e l2.10.3.5 Procedure A. Fill a disposable syringe with air and attach to the system 2 injection port.

B. Place the load/inject switch to load.

C. Inject air into the sample loop to remove any liquid from the sample line.

D. Place the sample needle into the 10 ppb chloride standard solution.

E. Using the syringe, draw the standard into the sample loop until liquid is seen entering the syringe.

F. Enter the conductivity scale setting into the integrator multiplica-tion factor. Push OP then 6, enter scale setting number, then press enter.

Simultaneously place the load/inject switch to inject and press the integrator start button. Place the load/inject switch to load after approximately 10 seconds.

After the chromatogram has run calibrate the integrator using the following steps:

Del Calib Calib ESTD Ref RTW RTW Cal 1 RT = (enter Cl retension time in minutes)

AMT = (enter Cl standard amount, 10 ppb)

ENTER With the load/inject switch in load, flush the sample loop with demineralized water.

Flush the sample loop with air.

K. Place the sample needle into the post accident sample.

L. Enter scale setting times 10 into the integrator multiplication factor. Push OP then 6, enter conductivity meter scale setting titles 10, then press enter.

M. Draw sample into sample loop until liquid is detected entering into the syringe.

N. Sioultaneously switch load/inject switch to inject and press inte-grator start. Switch load/inject to load position after 10 seconds'. The integrator will report ppb Cl.

0. Remove syringe and dispose of as high level radioactive waste.

P. Carefuly remove the'yringe needle from the sample vial 'and insert into the 14 ml evacuated vial. Dispose of vial as high level radioactive waste after excess liquid has been drawn from the sample room.
