ORP intends to award a sole-source contract modification to EnergySolutions Federal EPC, Inc., located at 2345 Stevens Drive, Suite 240, Richland, WA 99354. Work under Modification 006 will support development of the vitrification process for the Hanford Tank Waste Treatment and Immobilization Plant (WTP). The WTP is expected to treat both high-level waste (HLW) and low-activity waste (LAW). CLIN 0018: Enhanced LAW Glass Correlation The extensive glass formulation development work that underpins the WTP baseline LAW glasses was captured in a correlation that was developed by VSL and EnergySolutions that permits the calculation of the glass formulation required for each particular batch of LAW delivered to the LAW vitrification facility. The correlation is based on the baseline LAW glasses developed for the WTP with particular emphasis on those subjected to melter testing, especially in the LAW Pilot Melter. The composition outputs from the LAW correlation are designed such that they can tolerate expected processing variations without adversely affecting properties relevant to processing and product quality. This LAW correlation, along with the LAW glass property-composition models, will be used to control glass compositions for LAW vitrification at the WTP. Since the LAW correlation was developed, VSL and EnergySolutions have developed considerably higher waste loading LAW glass formulations under a program directed by ORP. These ORP glass formulations explored the limits of waste loading achievable in LAW glasses for various LAW streams with varying alkali and sulfate concentrations. While these ORP glasses provide much higher loadings, which result in substantial reduction in the amount of LAW glass to be produced at Hanford, in order to utilize them for LAW processing at the WTP new LAW glass property-composition models and a new LAW correlation that incorporates these enhanced glass formulations are required. Enhanced LAW glass property-composition models that incorporate these higher waste loading ORP compositions are being developed under separate tasks in the ORP program. The objective of the present task is to develop an Enhanced LAW Correlation, which along with the enhanced LAW glass property-composition models, can be used fo r LAW processing at the WTP with the higher waste loading ORP LAW glass formulations. The proposed work will include crucible scale testing to define and confirm the correlation that is developed. These results will then be used to select LAW glass formulations for initial DM100 melter tests to verify acceptable processing characteristics and absence secondary sulfate phase formation. The glass compositions for testing will be defined such that they can tolerate expected process variations in batching without adverse effects such as secondary phase formation on very slow processing rate. The results from testing will be analyzed to support development of an initial Enhanced LAW Correlation, which will be further refined and verified in subsequent work. CLIN 0019: Effect of Re Concentration on Re Retention One of the DM10 melter systems installed at the VSL has been equipped with the components that are prototypical of those in the WTP primary off-gas systems, specifically, the Submerged Bed Scrubber (SBS) and the Wet Electrostatic Precipitator (WESP); the DM10 system also includes a vacuum evaporator that allows testing to be conducted under recycle conditions. This is an efficient and economical system on which to obtain information on the compositions of the primary off-gas system effluents. Under a separate task, tests will be performed on this system to determine the compositions of the melter off-gas and effluent streams from the off-gas system, especially the SBS and the WESP, in order to assess potential disposition strategies for those streams. In these tests, rhenium will be added to the feed as a surrogate for technetium at a concentration of 0.05 wt% ReO2. Since the technetium concentration in the actual LAW WTP glasses is expected to be much lower (typically, around 3 ppm), the possible effects of concentration on retention in glass and partitioning to the SBS and WESP effluents are also of importance. In the present task, DM10 melter tests will be conducted with the ORPLA20 high waste loading glass composition at two different rhenium concentrations, one at about 10 ppm Re and the other at a concentration that is intermediate between that and the concentration of 0.05 wt% ReO2 in the glass. Since there are no data on technetium retention in high waste loading ORP glasses, one test will be conducted with 99mTc to determine single-pass Tc retention in the ORPLA20 glass formulation. Since ppm, or lower, levels of Re need to be analyzed in the glass, off-gas emissions, and SBS and WESP effluents, it is necessary to use analytical techniques with low detection limits and high accuracy and precision appropriate for these low concentrations; analysis by Induction Coupled Plasma ? Mass Spectroscopy (ICP-MS) will be used for this purpose. A large number of Re concentration measurements by ICP-MS will be required to determine Re partitioning between the glass, SBS, and WESP, and to track Re concentration evolution in the glass as a function of melter run time at low Re concentrations. CLIN 0020: High Waste Loading Glass Formulation Development for High-P HLW WTP flow-sheet projections indicate that a number of HLW streams to be processed at the WTP will have high phosphorous concentrations. These high-P HLW frequently contain other components such as Bi, Fe, Ca, and various rare earths. Previous studies for ORP have explored some of the HLW that contain relatively high concentrations of both Bi and P, but did not focus on HLW for which glass waste loading is limited solely by P, or those containing high concentrations P together with Fe, Ca, and/or rare earths. Interactions between P and Ca or rare earths are known and can lead to poor cold cap behavior and slow processing rates. The work in the present task will focus on developing high waste loading glass formulations with good processing characteristics to treat high-P Hanford HLW. The HLW compositions for the work will either be specified by ORP or selected in consultation with ORP. Crucible melts will be prepared and characterized to identify high waste loading glass compositions that meet all WTP processing and product quality requirements. Vertical gradient furnace tests will be used to screen the glass compositions for feed processing characteristics. The processing characteristics of a selected glass formulation will be assessed using DM100 melter testing. The melter test will be used to determine feed processing rate, cold-cap behavior, feed carry over, etc., and to identify any processing issues. CLIN 0021: Vitrification of Inorganic Ion-Exchange Media ORP is considering direct feeding of the LAW at Hanford to the vitrification facility with minimal or no pretreatment due to currently projected delays in the completion of the pretreatment facility. The currently planned baseline technology at the WTP for cesium removal is ion-exchange with elutable organic resins. The eluants will be directed to HLW vitrification and the spent ion-exchange resins will be stored and eventually disposed of as solid waste; however, the disposal path for the spent organic ion-exchange resins has not been finalized. Inorganic zeolite-based ion-exchange media were used successfully for cesium removal at the WVDP, where the loaded media were ground and mixed with the HLW sludge stream and vitrified. Testing has also been performed on other inorganic ion-exchange media such as crystalline silicotitanate (CST), which has been considered for applications at both DWPF and Hanford. The present task will focus on cesium removal from LAW using inorganic ion-exchange media and subsequent vitrification of the loaded media. The media that will be tested will be selected on the basis of projected Cs removal performance and compatibility with Hanford LAW as well as likely impacts on HLW vitrification and loadings. Candidate media will include zeolites and CST and the selected media will be tested for cesium removal performance in simulated Hanford LAW streams. Compatibility with vitrification in combination with Hanford HLW streams will be assessed through a series of crucible melts together with gradient furnace tests to provide an initial assessment of potential impacts on melting behavior and melt rates. The results will be used to assess the achievable loadings of the ion-exchange media and potential impacts on HLW loadings in the glass. The glass formulations will be tested for compliance with applicable WTP processing and product quality requirements. CLIN 0022: Long Term PCT Testing of LAW Glasses VSL has accumulated a large collection of on-going leach tests on a wide range of waste glasses that spans time periods of nearly 36 years. These tests employ a variety of test methods and include PCT tests that span time periods of 20 years or more (dating back to the original development of the PCT method). The PCT tests include tests in stainless steel and Teflon vessels, at temperatures from 20C to 90C, and over a range of ratios of the glass surface area to the solution volume (S/V). In the present task, long-term PCT test data on Hanford LAW glasses will be reviewed, analyzed, and reported. The results will be used to identify samples for which additional PCT leachate analyses would be useful and those samples will be collected and analyzed. The results will also be used to identify tests for which the altered glass and secondary phases will be analyzed. For those tests, selected vessels will be opened and small amounts of the solids will be removed and prepared for analysis that will include SEM/EDS and XRD. The data will be analyzed to determine factors such as reaction progress and secondary phase formation under various conditions, the onset of leach rate resumption, effects of surface to volume ratio on long-term PCT leaching, effects of temperature on PCT test results, and the long-term reproducibility of PCT test results. 17.Place of Contract Performance: Catholic University of America, Vitreous State Laboratory; Washington D.C. 20064. 18.Set-Aside Status: Not set-aside Competition Exception ORP has determined that this requirement can only be satisfied by the unique services offered by EnergySolutions Federal EPC, Inc. The statutory authority permitting this action is 41 U.S.C. 253(c)(1), where a determination has been made that the supplies or services required by the agency are available from only one responsible source and no other supplies or services will satisfy agency requirements. EnergySolutions Federal EPC, Inc., through its exclusivity agreement with Catholic University of America (CUA), Vitreous State Laboratory (VSL), is the only firm that is uniquely capable of providing the technical expertise and facilities necessary to complete the tasks described above. These tasks will be performed at the glass development laboratory and melter test facility at CUA-VSL, in Washington, D.C. Performance of these tasks requires the use of DM10, DM100, and DM1200 melters (the three melters reside at CUA-VSL); and expertise with LAW and HLW formulation/property relatio nships. Additionally, one of the tasks involves the compilation and analysis of leaching data that has been ongoing at the CUA for ca. 2 decades. EnergySolutions Federal EPC, Inc. is the only source with the required equipment (CUA-VSL houses the only DM10, DM100, and DM1200 melters in existence) and technical expertise to perform the work in the required timeframe. Unsolicited Proposals All responsible sources may submit a capability statement which shall be considered by the agency.
