Sampling Plan for the draining of the CST-B All sampling and analyses will be done in accordance with approved Chemistry group procedures.

Within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of commencement of draining of the CST-B, Chemistry will sample &

analyze the CST-B for tritium and other radioactive nuclides to determine if a discharge permit is required for draining.

If a discharge permit is required, Chemistry will provide one to the control room.

Chemistry will inform the control room directly if no discharge permit is required.

Chemistry will obtain samples the CST-B just prior to the commencement of drain down and then at every two (2) feet of level change thereafter.

Each sample set will include the following grab samples:

  • One 1-liter sample in a polypropylene bottle.
  • One 500 ml sample in a polypropylene bottle.
  • Three 50-ml samples in tissue flasks.

After obtaining the samples for each sample set, the technician will determine:

"* The conductivity of the CST-B by using the portable conductivity bridge and appropriate flow-through cell.

"* The dissolved oxygen concentration using chemet DO2 ampoules.

After obtaining each sample set, the technician will return to the chemistry lab and begin/continue with the following analyses on the grab samples:

  • Total Suspended Solids on the I-liter sample.
  • pH on the 500 ml sample.
  • Silica concentration on the 500 ml sample.
  • Chloride & Sulfate (anions) concentrations on one of the tissue flask samples.
  • Sodium concentration on one of the tissue flask samples.
  • Acidify the last tissue flask sample with 3-5 drops of concentrated nitric acid (Ultrex) and save for future metals analysis by ICP.

The Chemistry technician will record all results with sample date, time, & tank level on an appropriate log sheet (ChemDesk sample sheet #288123) and in the chemistry database.
