Title: Inter-Disciplinary Collaboration in Support of the Post-Standby TREAT Mission

Abstract

Although analysis methods have advanced significantly in the last two decades, high fidelity multi- physics methods for reactors systems have been under development for only a few years and are not presently mature nor deployed. Furthermore, very few methods provide the ability to simulate rapid transients in three dimensions. Data for validation of advanced time-dependent multi- physics is sparse; at TREAT, historical data were not collected for the purpose of validating three-dimensional methods, let alone multi-physics simulations. Existing data continues to be collected to attempt to simulate the behavior of experiments and calibration transients, but it will be insufficient for the complete validation of analysis methods used for TREAT transient simulations. Hence, a 2018 restart will most likely occur without the direct application of advanced modeling and simulation methods. At present, the current INL modeling and simulation team plans to work with TREAT operations staff in performing reactor simulations with MAMMOTH, in parallel with the software packages currently being used in preparation for core restart (e.g., MCNP5, RELAP5, ABAQUS). The TREAT team has also requested specific measurements to be performed during startup testing, currently scheduled to run from February to August of 2018. These startup measurements will be crucial inmore » validating the new analysis methods in preparation for ultimate application for TREAT operations and experiment design. This document describes the collaboration between modeling and simulation staff and restart, operations, instrumentation and experiment development teams to be able to effectively interact and achieve successful validation work during restart testing.« less

  • All projects are working toward a goal for describing the three dimensional nuclear topography in terms of relative spatial relationships among genes (specific DNA sequence). Methods are now being perfected to detect these genes, quantitatively and spatially, to perturb these genes specifically, and to measure the perturbation in order to assure specificity. We are developing methods to assay, after perturbation of the target DNA within living cells, whether or not only the target sequence are attacked while other sequences remain unharmed. We are now at the stage to do chemical gene modification or masking within living cells in a strictlymore » sequence-specific manner. Soon, we will be able to study the function and the physical location of each gene in living cells with exquisite specificity. 25 refs., 15 figs.« less
  • The main objectives of this Program Project is to develop strategy and technology for the study of gene structure, organization and function in a multi-disciplinary, highly coordinated manner. In Project I, Molecular Cytology, the establishment of all instrumentation for the computerized microscopic imaging system (CMIS) has been completed with the software in place, including measurement of the third dimension (along the Z-axis). The technique is now at hand to measure single copy DNA in the nucleus, single copy mRNA in the cell, and finally, we are in the process of developing mathematical approaches for the analysis of the relative spatialmore » 3-D relationship among the chromosomes and the individual genes in the interphasal nucleus. Also, we have a sensitive and reliable method for measuring single-stranded DNA breaks which will be useful for the determination of damage to DNA caused by ionizing radiation. In Project II, the mapping of restriction fragments by 2-D enzymatic and electrophoretic analysis has been perfected for application. In Project III, a major finding is that the binding constant and effectiveness of antisense oligonucleotide analogues, Matagen, can be significantly improved by substituting 2{prime}-O-methylribos methylphosphonate backbones for the current 2{prime}-deoxyribomethylphosphonate backbones. 15 refs., 10 figs., 2 tabs.« less
  • Proposals for demonstration work under the Department of Energy`s Mixed Waste Focus Area, during the 1996 through 1997 fiscal years included two applications of supercritical carbon dioxide to mixed waste pretreatment. These proposals included task RF15MW58 of Rocky Flats and task RL46MW59 of Hanford. Analysis of compatibilities in wastes and work scopes yielded an expectation of substantial collaboration between sites whereby Hanford waste streams may undergo demonstration testing at Rocky Flats, thereby eliminating the need for test facilities at Hanford. This form of collaboration is premised the continued deployment at Rocky Flats and the capability for Hanford samples to bemore » treated at Rocky Flats. The recent creation of a thermal treatment contract for a facility near Hanford may alleviate the need to conduct organic extraction upon Rocky Flats wastes by providing a cost effective thermal treatment alternative, however, some waste streams at Hanford will continue to require organic extraction. Final site waste stream treatment locations are not within the scope of this document.« less
