Take samples from the supernatant of each plastic tank to measure radioactivity<br />
concentration when water and precipitate have been separated. Write down the<br />
measurement results in the form, “Record 12: Radioactivity concentration in the<br />
pool water and precipitate before the 2nd treatment”.<br />
Discharge the supernatant with radioactivity concentration lower than the<br />
criteria for discharge using an engine pump. Adjust position of the hose nozzle of<br />
the engine pump not to raise or pump up the precipitate.<br />
Provide secondary treatment with the zeolite to the supernatant with<br />
radioactivity concentration higher than the criteria for discharge.<br />
