To evaluate the cesium removal capabilities of the caustic-washed R9120-B version of crystalline silicotitanate (CST) ion exchange media from Savannah River Site (SRS) waste during Tank Closure Cesium Removal (TCCR) column processing, batch contact kinetics tests were performed at 23 °C in SRS Average simulant.

Cesium Removal Using Crystalline Silicotitanate Tanks Focus Area DOE/EM-0415. Demonstrated at Hanford Site Richland, Washington and Oak Ridge Reservation ... IE-911 over organic ion-exchange resins for cesium removal. Ionsiv IE-911 is a CST sorbent developed jointly by DOE and industry. Ionsiv IE-911 was initially developed

CESIUM REMOVAL FROM SIMULATED SRS HIGH-LEVEL WASTE USING CRYSTALLINE SILICOTITANATE By D. D. WALKER SUMMARY This study measured the adsorption of cesium from simulated Savannah River Site liquid waste onto crystalline silicotitanate (CST) in equilibrium (IQ and ion exchange column tests. The tests used IONSIWtBIE-911(UOP LLC, Molecular Sieves ...

pretreatment will remove cesium from the waste stream using ion exchange (IX). The selected media for IX is crystalline silicotitanate (CST), product number UOP-IONSIV-R9140-B, manufactured by Honeywell UOP LLC (Des Plaines, IL). Testing was requested by Washington River Protection Solutions to better define IX processing using

SUMMARY This conceptual study investigates a generic in-tank cesium removal flowsheet using two inorganic ion exchange materials: titanates (CST) and IE-96 zeolites. The mathematical model derived for the study assumed a batch process where the ion exchange material and waste are brought into contact in a storage tank with optimal'mixing.

Using the PCST material at pH 1 or in 1, 2, and/or 3 M acid may require a cleanup column to remove Ti breakthrough. Separation of Ba from La. The Ba-La separation was conducted to assess the potential of a separation of Ra and Ac radioisotopes with a PCST column, with the stable isotopes serving as surrogates for the radioisotopes.

technology to filter solids and remove cesium from supernatant tank waste using non-elutable cesium ion-exchange media. The resulting treated tank waste will provide low-activity waste (LAW) feed to the Waste Treatment and Immobilization Plant (WTP) in support of hot commissioning and early operations.

This research concerns a design and construction of a bone mineral density (BMD) and bone mineral content (BMC) measurement system based on dual energy X-ray absorptiometry (DEXA). An indirect X-ray detector is designed by optical coupling CMOS sensor with image on the intensifying screen. A dedicated microcontroller X-ray apparatus is used as an X-ray source to capture two energy level X …

waste supernate by filtering to remove solids and processing through ion exchange columns to remove cesium. The ion exchange media is currently (since 2018) targeted to be crystalline silicotitanate (CST). This material has been produced as an engineered form (generally spherical beads) by Honeywell UOP LLC (Des Plaines, IL).

pretreatment will remove cesium from the waste stream using ion exchange (IX). The selected media for IX is crystalline silicotitanate (CST), product number UOP-IONSIV-R9140-B, manufactured by

cesium removal capabilities pe~formance.~ The Savannah River Resin (SRR) has been found to be more selective than CS-100 in removing cesium from Hanford- simulated waste. As a result, the use of the SRR could mean a reduction in the required size of the processing equipment as well as a reduction in the capital cost

The sorbent is crystalline silicotitanate (CST), an engineered material with a high capacity for sorbing cesium from alkaline wastes. The Cesium Removal System was demonstrated at Oak Ridge using Melton Valley Storage Tank (MVST) waste for feed. Demonstration operations began in September 1996 and were completed during June 1997.
