Download or read book Small Column Testing of Superlig 639 for Removal of 99Tc from Hanford Tank Waste Envelope C (Tank 241-AN-107). written by and published by . This book was released on 2000 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current BNFL Inc. flow sheet for pretreating Hanford High-Level tank wastes includes the use of Superlig(reg.sign)639 (SL-639) in a dual column system for removing technetium-99 (99Tc) from the aqueous fraction of the waste. This sorbent material has been developed and supplied by IBC Advanced Technologies, Inc., American Fork, UT. This report documents the results of testing the SL-639 sorbent with diluted waste [Na] (almost equal to) 5 M from Tank 241-AN-107 (an Envelope C waste, abbreviated AN-107) at Battelle Northwest Laboratories (BNW). The equilibrium behavior was assessed with batch contacts between the sorbent and the waste. Two AN-107 samples were used: (1) an archived sample from previous testing and (2) a more recent sample collected specifically for BNFL. A portion of the archive sample and all of the BNFL sample were treated to remove Sr-90 and transuranic elements (TRU). All samples had also been Cs decontaminated by ion exchange (IX), and were spiked with a technetium-95m ({sup 95m}Tc) pertechnetate tracer, {sup 95m}TcO4−. The TcO4− and total Tc K{sub d} values, assumed equal to the {sup 95m}Tc and 99Tc K{sub d}'s, respectively, are shown in Table S1. Values are averages of duplicates, which showed significant scatter. The total Tc K{sub d} for the BNFL sample is much lower than the TcO4−, indicating that a large fraction of the 99Tc is not pertechnetate.
Book Synopsis Evaluating Residence Time for SuperLig(R) 644 Columns with Simulated LAW Envelope B Solution by :
Download or read book Evaluating Residence Time for SuperLig(R) 644 Columns with Simulated LAW Envelope B Solution written by and published by . This book was released on 2003 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hanford River Protection Project Waste Treatment Plant (RPP-WTP) will be performing cesium and technetium ion exchange using SuperLig 644 and 639, respectively. Earlier work with LAW Envelope A (AN-105) simulant indicated that cesium adsorption by SuperLig 644 and perrhenate (pertechnetate analog) adsorption by SuperLig 639 are dependent on liquid volumetric flow rate during column loading. Acceptable lead column operation for both resins was attained (50 percent breakthrough at 100 column volumes) at maximum RPP-WTP design basis superficial velocities, but these results indicate that sorption kinetics could be limiting. As a follow-up to this previous work, LAW Envelope B (AZ-102) simulant was tested to verify column operability within the design basis. The simulant mimics the composition of low-activity waste solution from Tank 241-AZ-102 supernate in the Hanford waste tanks, which has higher cesium concentration than Envelopes A and C.

Book Synopsis The Effect of Temperature of SuperLig (R) 644 Cesium Removal from Simulated Hanford Tank Waste Supernate by :
Download or read book The Effect of Temperature of SuperLig (R) 644 Cesium Removal from Simulated Hanford Tank Waste Supernate written by and published by . This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Batch kinetic and column experiments have been carried out at 25, 35, and 45 Degrees C to examine the effect of temperature on SuperLig(R) 644 cesium (Cs) removal from simulated Hanford tank waste supernate. The simulated solution mimicked the composition of the low-activity waste supernate from tank 241-AN-105 in the U.S. DOE Hanford site. Small quantities of toxic metals, such as Cd, Cr, Fe, and Pb were spiked into the simulant to evaluate the metal's competitiveness with Cs for sorption on SuperLig(R) 644 resin. The results indicated that the temperature affects the removal of Cs and metal ions, although the effect was not the same for all metal ions. The extent of Cs removal decreased with an increase in temperature. The Cs capacity at breakthrough point was 0.015, 0.013, and 0.011-mmole/g dry resin at 25, 35 and 45 Degrees C, respectively. The column was effectively eluted to less than 1 Percent (0.1 C/Co) of the feed concentration with approximately 10 BVs of 0.5 M nitric acid. The resin showed limited affinity for toxic metal ions (Cr, Cd, Fe, and Pb) as compared to Cs. Based on the batch kinetic data, the Cs uptake of the resin was not hampered by the presence of the toxic metals in solution.
Book Synopsis Laboratory-Scale SuperLig 639 Column Tests With Hanford Waste Simulants by :
Download or read book Laboratory-Scale SuperLig 639 Column Tests With Hanford Waste Simulants written by and published by . This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of SuperLig{Reg} 639 column tests conducted at the Savannah River Technology Center (SRTC) in support of the Hanford River Protection Project - Waste Treatment Plant (RPP-WTP). The RPP-WTP contract was awarded to Bechtel National Inc. (BNI) for the design, construction, and initial operation of a plant for the treatment and vitrification of millions of gallons of radioactive waste currently stored in tanks at Hanford, WA. Part of the current treatment process involves the removal of technetium from tank supernate solutions using columns containing SuperLig{Reg} 639 resin. This report is part of a body of work intended to quantify and optimize the operation of the technetium removal columns with regard to various parameters (such as liquid flow rate, column aspect ratio, resin particle size, loading and elution temperature, etc.). The tests were conducted using nonradioactive simulants of the actual tank waste samples containing rhenium as a surrogate for the technetium in the actual waste. A previous report focused on the impacts of liquid flow rate and column aspect ratio upon performance. More recent studies have focused on the impacts of resin particle size, solution composition, and temperature. This report describes column loading experiments conducted varying temperature and solution composition. Each loading experiment was followed by high temperature elution of the sorbed rhenium. Results from limited testing are also described which were intended to evaluate the physical stability of SuperLig{Reg} 639 resin during exposure to repeated temperature cycles covering the range of potential processing extremes.
