[2G08] The results obtained from the 20 years of “Monju” plant data
(8)Purity management of sodium
Keywords:Monju, purity control condition , plugging meter, chemical analysis
At Monju, primary heat transport system, secondary heat transport system, and ex-vessel fuel storage tank sodium cooling system are corresponding to this clean-up system.
We evaluate the sodium purity control condition of these facilities for more than 20 years by the measurement of the plugging meter and chemical analysis, and confirm that we could maintain the purity with a value lower enough than the management targeted value.
