 Basic Test Results of Multi-nuclide Removal Equipment (1/2)
The targets for this test were ① and ③, (①reverse osmosis concentrated saltwater, ②
reverse osmosis freshwater and ③reverse osmosis contaminated water) which had high-radioactive concentration. (refer to ref. 4)
Confirmed that γ nuclide could be removed below detection limit (not detected, ND) against targeted nuclide (45 nuclides).
Confirmed that β nuclide could be purified to approx.  1/one-million~1/ten-million via  gross β radiation measurement. Identifying nuclides with significant density for further purification (scheduled to complete measurement at the beginning of March)
→After identifying nuclides, reflect on the removal plan.
Based on the gross α radiation measurement, α nuclide could be cleaned till less than detection limit (ND). Analyzing each nuclide’s density.
