MACRO1: a code to test a methodology for analyzing nuclear-waste management systems

Description: The code is primarily a manager of probabilistic data and deterministic mathematical models. The user determines the desired aggregation of the available models into a composite model of a physical system. MACRO1 then propagates the finite probability distributions of the inputs to the model to finite probability distributions over the outputs. MACRO1 has been applied to a sample analysis of a nuclear-waste repository, and its results compared satisfactorily with previously obtained Monte Carlo… more

Energy and protein production from pulp mill wastes. Final report, 15 Jun 1976-14 Jun 1979

Description: The goal of this research was to convert the organics and sulfur in sulfite spent liquor (SSL) now classified as pollutants from sulfite pulp mills, into synthetic methane and protein by means of a combination chemical-biological process. Ozonization was used to break the high molecular weight lignosulfonate molecules present in SSL into lower weight fractions which could be metabolized by methane-producing bacteria and protein-producing yeast. Ozonization experiments showed that this treatment… more

Actinide recovery from combustible waste: the Ce(IV)-NHO/sub 3/ system. Final report

Description: Actinides in ash can be leached effectively by refluxing with Ce(IV) in HNO/sub 3/; solubilization of actinide in ash was greater than or equal to 95% at ash concentrations to 30 g/l in stirred leachant. Plutonium and americium were the actinides present in the ash. Solubilized plutonium and americium were recovered from Ce(IV)-HNO/sub 3/ solution by solvent extraction. Extraction of plutonium into 30% tributyl phosphate in n-dodecane gave 99.99% recovery. The plutonium-depleted solution was th… more

National Waste Terminal Storage Program: containment system concepts for transporting Type B quantities of transuranic waste

Description: A series of shipping containment system preliminary concepts for Type B quantities of transuranic waste have been formulated. The concepts were based on hypothetical accident protection requirements, potential waste forms, and selected hardware design/considerations. The concepts consist of suggested waste system containment configurations and construction material suggestions. Analysis of the concepts, based on such features as fabrication ease and cost, utility, and payload efficiency, reveal… more

Minimum streaming current requirements for MFTF--revised by recent (r/sub p//a/sub i/) scaling in 2XIIB

Description: The minimum warm ion density necessary to effectively stablize the DCLC instability in MFTF represents a significant planning requirement. Thus a review of the theoretical predictions for MFTF stabilization is presented here including the recently revised (a/sub i//r/sub p/) scaling determined from tests with 2XIIB. For the assumptions given the total streaming current requirements range from 1500 to 2800 A, for T/sub e/ predicted from .66 to 1 keV and E/sub i/ approx. 50 keV.

A Sampling Plan for Use with Dynamic Calibration

Description: Dynamic calibration is a measurement control technique designed to facilitate the use of nondestructive assay for the control and accounting of special nuclear material. The implementation of dynamic calibration requires selection of an appropriate control measurement and sampling plan to provide traceability for the measurement system. A general sampling plan for use when the control measurement is an independent assay is presented with examples.

Alternative oxidizers for strip coal mine blasting agents. [Including study of possible substitutes; 53 references]

Description: Since ammonium nitrate manufacture is dependent on natural gas, a shortage in natural gas could lead to a critical shortage in coal by limiting the availability of ammonium nitrate for blasting. The purpose of this study was to assess the future availability of ammonium nitrate and to evaluate the potential of alternative oxidizers not dependent upon natural gas for use in blasting agents. Increased storage capacities and rapidly increasing levels of relativey cheap imported ammonia appear to e… more

Carbide Precipitation in the Heat Affected Zone of a GTA Weld in 21-6-9 Stainless Steel.

Description: Grain boundary precipitation was observed in a multipass GTA weld in 21-6-9 stainless steel. The precipitate was identified bby electron diffraction as Msub23 Csub6-type carbide. The presence of these carbide particles did not cause intergranular attack in standard corrosion tests.

Hydrogen recycling in tandem mirror machines

Description: This paper describes hydrogen recycling in tandem mirror machines. In TMX, hydrogen (or deuterium) is introduced by the neutral beam injection system and by the solenoid gas feed system. Pumping is achieved by titanium gettering on liquid nitrogen panels. Mirror machine recycling differs from that in a tokamak. In mirrors, plasma losses are mainly to the large volume at the ends of the machine, remote from the hot plasma region. Similar techniques have been employed on 2XIIB. The design of the … more

Deuterium plasma-material wall interactions. Progress report, 1 May 1978--30 Apr 1979

Description: During the past year we studied in detail plasma-first wall material damage induced by unipolar arcing. Unipolar arcing damage was analyzed as a function of material, surface preparation and microstructure. Unipolar arcing was found on all materials tested and the percentage of the surface area affected by arcing was similar for different metals. The severity of unipolar arcing was found to be very sensitive to microstructure. This was deduced through extensive study of different heat treatment… more
