strontium reduced Desalinated water Treated water with ALPS （） Treatment capacity Concentrated saltwater after treated with desalination equipment Treated water with ALPS （radionuclides except Tritium removed ） Cesium adsorption apparatus KURION modified to remove Strontium（600m3/day） Risk reduction of contaminated water
The source and mechanism of deposition of the primary tungsten mineralization are deduced from five facts 1 the radiogenic strontium isotopic data of stage 1 scheelites 87 Sr 86 Sr = occurring together with normal crustal neodymium isotopic compositions ε CHUR t 1 = − 2 unusually high U concentrations up to 74 ppm in stage 1
Separation of radionuclides from cooling water was introduced just after the accident leading to the Advanced Liquid Processing System ALPS introduction in 2013 that was designed to remove 62
Kurion and Sarry in order to remove Strontium and then further decontaminated through ALPS There will be continuous effort to decrease the amount of groundwater running into the reactor buildings with new
for ALPS based on the results of the confirmatory testing and the water flow test using to reduce the sludge amount Purpose of the Confirmatory Testing In order to improve performance to remove Sr 89 Sr 90 and Y 90 in a colloidal state the hole size of the filter Strontium carbonate CaCO 3 MgCO 3 Calcium carbonate Magnesium
The source and mechanism of deposition of the primary tungsten mineralization are deduced from five facts 1 the radiogenic strontium isotopic data of stage 1 scheelites 87 Sr 86 Sr = occurring together with normal crustal neodymium isotopic compositions ε CHUR t 1 = − 2 unusually high U concentrations up to 74 ppm in stage 1
The results obtained from the strontium ions adsorption experiments showed that the MCS was an effective material to remove strontium ions from aqueous solutions And most importantly the adsorption process was safely and easily controlled the separation of MCS from solutions after adsorption was fast because of the magnetic modification
I understand that this incident occurred during the washing process at the facility to remove cesium and strontium before the ALPS purification process In addition to this facility there are other similar purifying facilities I have heard that in the purifying process at those facilities purification will be conducted on the premise of
This he said ignored the possibility that there would be variation among the tanks potentially overlooking harmful levels of more radioactive substances such as cesium 137 and strontium 90
After the concentration of Cesium and Strontium contained in the contaminated water is reduced Multi nuclide Removal Facility ALPS eventually removes most of the radioactive materials except Tritium The treated water from which Cesium and Strontium have been already reduced will require further treatment by ALPS to remove additional
The discharge process using an Advanced Liquid Processing System ALPS would take decades to complete strontium and plutonium The system is also not able to remove tritium the radioactive isotope of hydrogen Masanobu Sakamoto president of JF Zengyoren Japan Fisheries Cooperatives said in June that the group "cannot support the
quite early by testing [4] For cesium and strontium removal in ALPS the highly selective materials CsTreat ® and SrTreat were selected ALPS is a multiple phase system to remove all those required radionuclides [5] There are two precipitation phases in a pretreatment facility and after these 14 ion exchange vessels plus 2 ion
Magnetic Fe 3 O 4 particles modified sawdust MCS was prepared by using chitosan as the bridging reagent and characterized by FTIR analysis and the results indicated that sawdust was successfully modified by magnetic Fe 3 O 4 particles by connection of chitosan The results obtained from the strontium ions adsorption experiments showed that the MCS was
The water is then transferred to the Advanced Liquid Processing System ALPS Here semipermeable membranes and ion exchangers are used to reduce the concentration of 62 other radioactive isotopes
Furthermore ALPS equipment contains filters that can remove solid objects in the water prior to treatment If ALPS treated water is to be discharged into the environment it will be purified to ensure that the sum of the ratios of legally required concentrations with the exception of tritium is less than 1 secondary treatment
This includes contaminated water that has been treated by the Advanced Liquid Processing System ALPS which removes most of the radioactive contamination with the exception of tritium It also includes water that has been treated to remove strontium The average tritium concentration of the stored water is about 730 000 becquerels per litre
Strontium 90 90Sr and Cesium 134 and 137 134Cs and 137Cs at concentrations of up to 440 total beta Bq/liter of somewhat lower levels of Cs The requirements are to remove the radionuclides to an acceptable level 30 Bq/liter for 90Sr or lower and 60 Bq/l for 134Cs and 90 Bq/l 137Cs or lower
1：ALPS remove salt filtered water content used as coolant Strontium Treated Desalination facility Water Storage Tanks reduce Remove most of reactor Caesium and the radioactive Strontium materials groundwater buildings Multi nuclide water
2018 Among the various isotope systems the analysis of strontium isotopes 87 Sr/ 86 Sr has been 80 identified as a promising approach for discriminating the origin of timber particularly at a fine scale 81 D Andrea et al 2023; Vlam et al 2018 This is because strontium is a soil derived marker that 82
