This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: PNL evaluated three polymeric materials for Cs removal efficiency from a simulated Hanford Neutralized Current Acid Waste (NCAW) supernatant liquid using 200 mL ion exchange columns. Cs loadings (mmole Cs/g resin) were 0.20, 0.18, and 0.039 for Super Lig 644, R-F, and CS-100 (0.045, 0.070, 0.011 mmole Cs/mL resin). Elution of each resin material with 0.5 M HNO[sub 3] required 3.5, 7.0, and 3.2 cv to reach 0.1 C/C[sub 0] for the respective materials, resulting in volume compressions of 27, 20, and 6.9. Peak Cs concentrations during elution was 185, 38.5, and 27.8 C/C[sub 0]. SuperLig 644 had the highest Cs loading per gram in NCAW and the greatest volume compression on aci elution. Because of high density and poor elution, R-F had the highest Cs loading per unit volume and lower volume compression. CS-100, the baseline material for Cs removal at Hanford, was inferior to both SuperLig 644 and R-F in terms of Cs loading and selectivity over sodium.

Download or read book Cesium Recovery Using Savannah River Laboratory Resorcinol formaldehyde Ion Exchange Resin written by and published by . This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new ion exchange resin has been developed by the Savannah River Laboratory (SRL) for the recovery of radioactive 137Cs from alkaline wastes produced by reprocessing fuels from nuclear reactors. The SRL resin is a condensation polymer made from resorcinol and formaldehyde. It has been shown to be stable to chemical and radiation attack in the highly concentrated and caustic supernatant waste. Small-scale testing was completed with excellent results. The Pacific Northwest Laboratory (PNL) was requested to initiate a test program designed to provide additional experimental data needed to support further consideration of the resorcinol-formaldehyde ion exchange treatment for the Savannah River Site (SRS) alkaline waste. 2 refs., 2 figs., 5 tabs.
Download or read book SuperLig TM 644 Ion Exchange Resin Stability in Nitric Acid at Elevated Temperatures written by C. A. Nash and published by . This book was released on 2003 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Hanford River Protection Project Waste Treatment Plan (RPP-WTP) flowsheet, opportunity exists for the organic SuperLig 644(TM) cation exchange resin to come in contact with concentrated (5 M) nitric acid at elevated temperatures in the acid recovery evaporator. These are similar conditions where other ion exchange resin (albeit usually anion) column explosions have occurred. The objective of these tests was to examine potential hazards by exposing the resin to conditions expected in the facility and examining the composition of the reaction products and their reactivity.

Book excerpt: SuperLig(R) 644 (Trademark of IBC Advanced Technologies, American Fork, Utah) is an elutable resin that contains covalently bound macrocyclic ligands with high affinity for cesium in alkaline solution in the presence of sodium and potassium. The resin has been selected as the baseline ion exchange material for cesium removal from Hanford tank waste solutions. Extensive experimental investigations conducted at the Savannah River Technology Center (Aiken, South Carolina) and Battelle Pacific Northwest National Laboratory (Hanford, Washington) with simulated Hanford tank waste solutions indicated that SuperLig(R) 644 resin has adequate density and low-cycle physical durability, sufficient chemical stability, sufficient cesium sorption capacity and selectivity. Radioactive Hanford Site tank waste samples from tanks 241-AN-103, 241-AN-102 and 241-AZ-102 confirmed the simulant results.

Download or read book Storage and Aging Effects on Spherical Resorcinol Formaldehyde Resin Ion Exchange Performance written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bechtel National, Inc. (BNI) is evaluating the alternate Cs ion exchanger, spherical resorcinol-formaldehyde (RF), for use in the River Protection Project-Waste Treatment Plant (RPP-WTP).() Previous test activities with spherical RF indicate that it has adequate capacity, selectivity, and kinetics to perform in the plant according to the flowsheet needs. It appears to have better elution and hydraulic properties than the existing alternatives: ground-gel RF and SuperLig® 644 (SL 644).() To date, the spherical RF performance testing has been conducted on freshly manufactured resin (within ~2 months of manufacture). The ion exchange resins will be manufactured and shipped to the WTP up to 1 year before being used in the plant. Changes in the resin properties during storage could reduce the capacity of the resin to remove Cs from low-activity waste solutions. Active sites on organic SL-644 resin have been shown to degrade during storage (Arm et al. 2004). Additional testing was needed to study the effects of storage conditions and aging on spherical RF ion exchange performance. Variables that could have a significant impact on ion exchange resins during storage include storage temperature, medium, and time. Battelle--Pacific Northwest Division (PNWD) was contracted to test the effects of various storage conditions on spherical RF resin. Data obtained from the testing will be used by the WTP operations to provide direction for suitable storage conditions and manage the spherical RF resin stock. Storage test conditions included wet and dry resin configurations under nitrogen at three temperatures. Work was initially conducted under contract number 24590-101-TSA-W000-00004 satisfying the needs defined in Appendix C of the Research and Technology Plan() TSS A-219 to evaluate the impact of storage conditions on RF resin performance. In February 2007, the contract mechanism was switched to Pacific Northwest National Laboratory (PNNL) Operating Contract DE-AC05-76RL01830.
