Investigation of in situ hydrothermal oxidative destruction of NDMA

Description: Rate constants for the aqueous oxidation of N-nitrosodimethylamine (NDMA) have been measured in aqueous phosphate-buffered solutions using Dickson-type vessels. The initial NDMA concentrations ranged from 2.5 to 2.8 ppm and reaction temperatures varied from 180 C to 220 C. Quantitation of NDMA was performed by gas chromatography-mass spectrometry (GC-MS) using selected ion monitoring (SIM). NDMA loss with concomitant production of nitrite and nitrate confirmed that mineralization of NDMA occurr… more

Interim report on task 1.4: impurity effects part 1 of 2 to Lawrence Livermore National Laboratory under contract b345772

Description: From our work with baseline ceramics containing Pu, or Ce substituted for Pu, doped with sets of inactive impurity ions (with supposedly the same valency) and sintered in different atmospheres, the conclusion is that all ions of similar size and valency are indeed crystal-chemically equivalent unless there are volatility problems. However, the real question appears to be what are the appropriate valency states of the multivalent impurity ions under given sintering conditions. For example, when … more

Engineering research, development and technology report

Description: Nineteen ninety-eight has been a transition year for Engineering, as we have moved from our traditional focus on thrust areas to a more focused approach with research centers. These five new centers of excellence collectively comprise Engineering's Science and Technology program. This publication summarizes our formative year under this new structure. Let me start by talking about the differences between a thrust area and a research center. The thrust area is more informal, combining an importa… more

Sensor modules for wireless distributed sensor networks

Description: A national security need as well as environmental monitoring need exists for networks of sensors. The advantages of a network of sensors over a single sensor are improved range, sensitivity, directionality, and data readability. Depending upon the particular application, sensors can be acoustic, chemical, biological, thermal or inertial. A major desire in these sensor networks is to have the individual sensor and associated electronics small and low enough in power that the battery can also be … more

PC/FRAM, Version 3. 2 User Manual

Description: This manual describes the use of version 3.2 of the PC/FRAM plutonium isotopic analysis software developed in the Safeguards Science and Technology Group, NE-5, Nonproliferation and International Security Division Los Alamos National Laboratory. The software analyzes the gamma ray spectrum from plutonium-bearing items and determines the isotopic distribution of the plutonium 241Am content and concentration of other isotopes in the item. The software can also determine the isotopic distribution … more

Evaluation of Infrasound and Strobe Lights to Elicit Avoidance Behavior in Juvenile Salmon and Char.

Description: Experimental tests were conducted using hatchery reared and wild juvenile chinook salmon Oncorhynchus tshawytscha, eastern brook trout Salvelinus fontinalis, and rainbow trout O. mykiss to determine specific behavior responses to infrasound (<20 Hz) and flashing strobe lights. Caged fish were acclimated in a static test tank and their behavior was recorded using low light cameras. Species specific behavior was characterized by measuring movements of the fish within the cage as well as observ… more

Radionuclide Coefficients for the BNL Site: For the Saturated and Unsaturated Zones

Description: The partition coefficient (K{sub d}) is defined as the concentration of a species of interest on the solid phase divided by the concentration of that species in the liquid phase, at steady-state. Therefore the lower the K{sub d}, the less sorption takes place. It is a parameter that is readily incorporated in chemical transport models. The K{sub d} approach to the partitioning of contaminants between soil and water in groundwater flow systems, is based on the assumption that sorption reactions … more

Lake Roosevelt Rainbow Trout : Habitat/Passage Improvement Project : Annual Report 1998.

Description: Lake Franklin D. Roosevelt was created with the completion of the Grand Coulee Dam in 1942. The lake stretches 151 miles up-stream to the International border between the United States and Canada at the 49th parallel. Increased recreational use, subsistence and sport fishing has resulted in intense interest and possible exploitation of the resources within the lake. Previous studies of the lake and its fishery have been limited. Early studies indicate that natural reproduction within the lake a… more

Kootenai River Fisheries Investigations : Rainbow Trout Recruitment : Period Covered: 1997.

Description: The objective of this study was to determine if juvenile production is limiting the population of rainbow trout Oncorbynchus mykiss in the Idaho reach of the Kootenai River. We used snorkeling and electrofishing techniques to estimate juvenile rainbow trout abundance in, and outmigration from, the Deep, Boulder, and Myrtle creek drainages in Idaho. The total population estimates for the three drainages estimated in 1997 were 30,023; 763; and 235; respectively. A rotary-screw trap was utilized t… more

Models for the Configuration and Integrity of Partially Oxidized Fuel Rod Cladding at High Temperatures - Final Design Report

Description: Models were designed to resolve deficiencies in the SCDAP/RELAP5/MOD3.2 calculations of the configuration and integrity of hot, partially oxidized cladding. The modeling was improved in five areas. First, the configuration defined for melted metallic cladding retained by an adjacent oxide layer was improved. Second, the empirical model to account for the effect on oxidation of intact cladding is not significantly reduced by the presence of a rather high concentration of relocated material. Thir… more

Development of a SREX Flowsheet for the Separation of Strontium from Dissolved INEEL Zirconium Calcine

Description: Laboratory experimentation has indicated that the SREX process is effective for partitioning 90 Sr from acidic radioactive waste solutions located at the Idaho Nuclear Technology and Engineering Center. These laboratory results were used to develop a flowsheet for countercurrent testing of the SREX process with dissolved pilot plant calcine. Testing was performed using 24 stages of 2-cm diameter centrifugal contactors which are installed in the Remote Analytical Laboratory hot cell. Dissolved R… more

Preliminary Design Report for Modeling of Hydrogen Uptake in Fuel Rod Cladding During Severe Accidents

Description: Preliminary designs are described for models of hydrogen and oxygen uptake in fuel rod cladding during severe accidents. Calculation of the uptake involves the modeling of seven processes: (1) diffusion of oxygen from the bulk gas into the boundary layer at the external cladding surface, (2) diffusion from the boundary layer into the oxide layer, (3) diffusion from the inner surface of the oxide layer into the metallic part of the cladding, (4) uptake of hydrogen in the event that the clad-ding… more
