Evaluation of concentrations of hazardous components to support removal of the Tank 48 thermowell

Description: In support of start-up activities for the In Tank Precipitation (ITP) process, a thermowell is scheduled to be removed from Tank 48. Disposal of the thermowell in the Solid Waste Disposal Facility (SWDF) requires manifesting the quantities of several radioisotopes and, equally important, declaring that the waste package is nonhazardous. Sampling of the waste in the package (i.e., the thermowell) to determine quantities of hazardous materials or to perform a Toxicity Characteristic Leaching Proc… more

Solid waste operations complex engineering verification program plan

Description: This plan supersedes, but does not replace, the previous Waste Receiving and Processing/Solid Waste Engineering Development Program Plan. In doing this, it does not repeat the basic definitions of the various types or classes of development activities nor provide the rigorous written description of each facility and assign the equipment to development classes. The methodology described in the previous document is still valid and was used to determine the types of verification efforts required. … more

Transport suppression by diamagnetic phase shift as a possible mechanism to the L to H transition

Description: In the presence of a pressure gradient, the phase velocity of drift-wave or ITG-mode turbulence is different from the poloidal E{times}B rotation velocity of guiding centers. This results in an E{times}B turbulent particle diffusion being suppressed by the phase shift due to the diamagnetic rotation velocity {upsilon}{sub {theta}} = (c/enB)dP/dr. This shift cannot be eliminated by a frame change and affects the plasma transport. For {upsilon}{sub {theta}} well above the turbulent velocity v = {… more

Mass transfer model for two-layer TBP oxidation reactions

Description: To prove that two-layer, TBP-nitric acid mixtures can be safely stored in the canyon evaporators, it must be demonstrated that a runaway reaction between TBP and nitric acid will not occur. Previous bench-scale experiments showed that, at typical evaporator temperatures, this reaction is endothermic and therefore cannot run away, due to the loss of heat from evaporation of water in the organic layer. However, the reaction would be exothermic and could run away if the small amount of water in th… more

Level maintenance for Tank 101-SY mitigation-by-mixing test. Revision 2

Description: The Phase A, Phase B and Full Scale testing portions of the Mitigation-By-Mixing Test have demonstrated the effectiveness of the Mixer Pump to maintain the waste in tank 101-SY in the desired mitigated state. The operation of the 101-SY Mixer Pump for short periods of time results in a controlled release of hydrogen gas in concentrations well below the established safety limits. Additionally, it has been shown that operation of the pump on a regular schedule minimizes the historical generation … more

DACS upgrade acceptance test procedure

Description: The readiness of the Data Acquisition and Control System (DACS) to provide monitoring and control of the mixer pump, directional drive system, and the instrumentation associated with the SY-101 tank and support systems, and the proper functioning of the DACS with new Model 984-785 Programmable Logic Controllers (PLCs), new MODBUS PLUS version 2.01 software for the PLCs, and version 3.72 of the GENESIS software will be systematically evaluated by performance of this procedure. The DACS, which is… more

Plutonium and tritium produced in the Hanford Site production reactors

Description: In a news release on December 7, 1993, the Secretary of Energy announced declassification action that included totals for plutonium and tritium production in the Hanford Site production reactors. This information was reported as being preliminary because it was not fully supported by documentation. Subsequently, production data were made available from the US Department of Energy-Headquarters (DOE-HQ) records that indicated an increase of about one and one-half metric tons in total plutonium pr… more

Application of infrared imaging in ferrocyanide tanks

Description: This report analyzes the feasibility of using infrared imaging techniques and scanning equipment to detect potential hot spots within ferrocyanide waste tanks at the Hanford Site. A hot spot is defined as a volumetric region within a waste tank with an excessively warm temperature that is generated by radioactive isotopes. The thermal image of a hot spot was modeled by computer. this model determined the image an IR system must detect. Laboratory and field tests of the imaging system are descri… more

Tank characterization report for double-shell Tank 241-AW-105

Description: In May 1990, double-shell Tank 241-AW-105 was sampled to determine proper handling of the waste, to address corrosivity and compatibility issues, and to comply with requirements of the Washington Administrative Code. This Tank Characterization Report presents an overview of that tank sampling and analysis effort, and contains observations regarding waste characteristics. It also addresses expected concentration and bulk inventory data for the waste contents based on this latest sampling data an… more

An assessment of the potential for a steam bump in Hanford Waste Tank 241-C-106

Description: This document is a preliminary assessment of the potential for a ``steam bump`` in Tank 241-C-106. The assessment is based on currently available data from significant transients which occurred in Tank C-106. Recommendations are made for additional data needs to clarify the current behavior of this tank. General criteria are provided for making decisions on removing or returning to work restrictions on Tank Farm operations. Also provided are additional actions which should be taken on C-106 to … more

Excitation of a quantal and a classical gas in a time-dependent potential

Description: We report on computer simulations of oscillating Woods-Saxon or cavity potentials filled with either a classical or a quantal gas of independent particles. We have now available of the order of 600 excitation histories of such gases undergoing usually one period of oscillation (but sometimes several), classified according to frequency and multipolarity of the oscillation and of the degree of diffuseness of the potential. We are still in the process of displaying and interpreting some of the res… more

Hazard assessments of double-shell flammable gas tanks

Description: This report is the fourth in a series of hazard assessments performed on the double-shell flammable gas watch list tanks. This report focuses on hazards associated with the double-shell watch list tanks (101-AW, 103-AN, 104-AN, and 105-AN). While a similar assessment has already been performed for tank 103-SY, it is also included here to incorporate a more representative slurry gas mixture and provide a consistent basis for comparing results for all the flammable gas tanks. This report is inten… more

Saltcrete formulation

Description: The information gathered since the first report shows that the currently generated waste and most of the waste in inventory has low concentrations of hazardous chemicals and is certifiable for disposable. This is based on preliminary analyses. Sampling and analysis for the purpose of gathering the legally defensible data required for certification and permanent disposal is in progress. The main technical issue is the expansion of the waste form. Some of the cemented waste expands and damages th… more

Engineering evaluation of intrusion prevention strategies for single-shell tanks

Description: In this study, previously implemented actions to prevent liquid intrusion into out-of-service single-shell tanks (SSTs), i.e., interim isolation or partial interim isolation, are investigated and expanded to identify additional cost-effective intrusion prevention techniques that could be reasonably taken until SSTs are ready for waste retrieval. Possible precipitation, groundwater, and condensation pathways and internal tank connections that could provide possible pathways for liquids are exami… more

Review of consequences of uranium hydride formation in N-Reactor fuel elements stored in the K-Basins

Description: The 105-K Basins on the Hanford site are used to store uranium fuel elements and assemblies irradiated in and discharged from N Reactor. The storage cylinders in KW Basin are known to have some broken N reactor fuel elements in which the exposed uranium is slowly reacting chemically with water in the cylinder. The products of these reactions are uranium oxide, hydrogen, and potentially some uranium hydride. The purpose of this report is to document the results f the latest review of potential, … more
