The LANL Physical Inventory Program

Description: The LANL physical inventory program (statistically based) provides assurance that the inventory is represented to the defined confidence levels. In addition, it establishes a benchmark to prove that the inventory is accurately stated. The LANL's Physical Inventory Program for nuclear materials requires the performance of periodic physical inventories and special inventories of nuclear material. The Inventory Program also requires the reconciliation of inventory measurements with previously esta… more

Concepts for fabrication of inertial fusion energy targets

Description: Future inertial fusion energy (IFE) power plants will have a Target Fabrication Facility (TFF) that must produce approximately 500,000 targets per day. To achieve a relatively low cost of electricity, the cost to produce these targets will need to be less than approximately $0.25 per target. In this paper the status on the development of concepts for a TFF to produce targets for a heavy ion fusion (HIF) reactor, such as HYLIFE II, and a laser direct drive fusion reactor such as Sombrero, is dis… more

Direct Dose Consequences Due to DOE-STD-1027 Threshold Values

Description: The purpose of this paper is to discuss the potential direct dose consequences to facility workers and/or co-located workers from a Hazard Category 2 or 3 nuclear facility or a less than Hazard Category 3 radiological inventory. At the Idaho National Engineering and Environmental Laboratory (INEEL), the safety analysis for several Hazard Category 3 nuclear facilities had to be revisited and the direct dose consequences associated with the facility radiological inventory had to be analyzed and i… more

Approach for enhancing nuclear materials tracking and reporting in waste

Description: Recent policy from the Department of Energy/Office of Safeguards and Security (DOE/OSS) has identified the need to report nuclear materials in waste in a manner that is consistent with the Department of Energy's Nuclear Materials Information System (NMIS), which uses Form 471 as its official record. NMIS is used to track nuclear material inventories while they are subject to safeguards. This requirement necessitates the reevaluation of existing business practices that are used to track and repo… more

INVENTORY ABSTRACTION

Description: The purpose of the inventory abstraction, which has been prepared in accordance with a technical work plan (CRWMS M&O 2000e for ICN 02 of the present analysis, and BSC 2001e for ICN 03 of the present analysis), is to: (1) Interpret the results of a series of relative dose calculations (CRWMS M&O 2000c, 2000f). (2) Recommend, including a basis thereof, a set of radionuclides that should be modeled in the Total System Performance Assessment in Support of the Site Recommendation (TSPA-SR) … more

Microbially Mediated Immobilization of Contaminants Through In Situ Biostimulation: Scale up of EMSP Project 55267

Description: The overall goal of the proposed research is to provide an improved understanding and predictive capability of the mechanisms that allow metal-reducing bacteria to be effective in the bioremediation of redox sensitive toxic metals and radionuclides. The study is motivated by the likelihood that subsurface metal-reducing bacteria can be stimulated to effectively alter the redox state of contaminants so that they are immobilized in situ for long time periods. The work described in this proposal w… more

Partial support for the International Global Atmospheric Chemistry Core Project Office

Description: IGAC provides an international framework for the planning, coordination, and execution of atmospheric--biospheric research with emphasis on projects which require resources beyond the capabilities of any single nation. The development of chemical emission inventories by IGAC scientists, the development and intercomparison under IGAC leadership of existing chemical transport models, the analysis of data gathered during IGAC-sponsored field campaigns, etc., has provided new scientific information… more

Automatic Software Processing for Inventories of Nuclides (ASPIN)

Description: EQ6 users have difficulties tracking isotopic concentrations in a system with chemical and nuclear decay reactions. The capability to track isotopic concentrations is particularly important for simulating the degradation of the spent nuclear fuels. Isotopic tracking is necessary to evaluate the criticality risk associated with fissile material relocation inside of a disposal container. A code called ASPRIN (Automatic Software PRocessing, Inventories of Nuclides) was created to allow isotopic tr… more

User Instructions for the Systems Assessment Capability, Rev. 0, Computer Codes. Volume 1: Inventory, Release, and Transport Modules

Description: One activity of the Department of Energy's Groundwater/Vadose Zone Integration Project is an assessment of cumulative impacts from Hanford Site wastes on the subsurface environment and the Columbia River. Through the application of a system assessment capability (SAC), decisions for each cleanup and disposal action will be able to take into account the composite effect of other cleanup and disposal actions. The SAC has developed a suite of computer programs to simulate the migration of contamin… more

Total Inventory of Selected Radionuclides in Old Solvent Tanks S1 Through S22

Description: The total inventory of fourteen radionuclides, three metals, and volatile organic compounds (VOCs) has been calculated for the twenty-two Old Solvent Tanks (OSTs). The inventory calculations are based upon extensive characterization data of the multiple liquid and sludge samples taken from the OSTs. In addition, the total inventory of sixteen actinides (including error) has been calculated. The actinide inventory will be useful for criticality safety considerations.

Engineering analysis for disposal of depleted uranium tetrafluoride (UF{sub 4}).

Description: This report presents and evaluates options for disposing of depleted uranium in the chemical form of uranium tetrafluoride (UF{sub 4}). Two depleted uranium inventories are considered. One results from the original U.S. Department of Energy (DOE) inventory of 560,000 metric tons (te) of depleted uranium hexafluoride (UF{sub 6}); the other inventory is the original DOE inventory augmented by 145,000 te of depleted UF{sub 6} from the United States Enrichment Corporation. Preconceptual designs are… more

Tritium Inventory in ARIES-AT

Description: This report documents an investigation into the tritium inventory expected in the ARIES-AT fusion reactor. ARIES-AT features silicon carbide fibers in a silicon carbide matrix as its primary construction. It uses the same fusion power core as the previous ARIES-RS. Based on experimental results of several researchers, consideration was given to swelling, sputtering, film coatings, erosion, and implantation. Estimates were made of tritium inventory using the TMAP4 code. About 700 g of tritium ma… more
