Estimating and coping with public response to radioactive waste repository siting

Description: The siting and construction of a radioactive waste disposal operation is likely to be controversial in the communities being considered, and at the state and national levels as well. Public response can be conceptualized at two levels: individual, and group or organizational. At the individual level, public response is the behavior of people motivated by their attitudes, knowledge, and perceptions of radioactive waste and its hazards and risks. On the group or organizational level, public respo… more

Operational parameters of a 2. 0-MeV RFQ linac

Description: After extensive upgrading, our radio-frequency quadrupole (RFQ) linac is again installed on the accelerator test stand (ATS). The measured parameters of the RFQ, such as the output transverse emittance, transmitted beam, average energy, and energy spread is presented.

DT-burning upgrade to MFTF-B

Description: To improve MFTF-B, one must raise the ion energy and the electrostatic confining potential. This requires higher beam energy (200 keV in this case) and, to preserve end-plug adiabaticity and hold higher plasma density in the central cell, a higher level of magnetic field. In the MFTF Upgrade we also want to incorporate the new end plug configuration first invented for the MARS reactor. This new magnet design is compared with the present MFTF-B magnet set. The differences include the addition of… more

Electron motion in solenoidal magnetic fields using a first order symplectic integration algorithm

Description: The use of nonsymplectic procedures in particle tracing codes for relativistic electrons leads to errors that can be reduced only at the expense of using very small integration steps. More accurate results are obtained with symplectic transformations for position and momentum. A first-order symplectic integration procedure requires an iterative calculation of the new position coordinates using the old momenta, but the process usually converges in three or four steps. A first-order symplectic al… more

Modeling level structures of odd-odd deformed nuclei

Description: A technique for modeling quasiparticle excitation energies and rotational parameters in odd-odd deformed nuclei has been applied to actinide species where new experimental data have been obtained by use of neutron-capture gamma-ray spectroscopy. The input parameters required for the calculation were derived from empirical data on single-particle excitations in neighboring odd-mass nuclei. Calculated configuration-specific values for the Gallagher-Moszkowski splittings were used. Calculated and … more

Field enhancement of a 12. 5-T magnet using holmium poles

Description: Unlike conventional ferromagnetic materials such as iron and Supermendur, which produce saturation magnetization fields of approximately 2 T, several of the rare-earth elements (holmium, terbium, erbium, gadolinium, and dysprosium) yield saturated fields of nearly 4 T. This property makes these rare-earth metals particularly attractive as flux concentrators for use in superconducting magnets. This report concerns the use of holmium inserts to enhance the peak useful field of the nominally 12.5-… more

Plasma-surface interactions in large tandem mirror devices - MFTF-B

Description: Present experiments on TMX-U and modeling of MFTF-B indicate that plasma-surface interactions can be controlled in MFTF-B. The MFTF-B configuration uses a hot electron population created by ECRH and a sloshing-ion population created by neutral beams in the thermal barrier region to create a potential that confines the central cell ions. Neutral beams and ICRH are used to heat the central cell ions. Plasma-surface interactions can be minimized at radial surfaces by control of the axial confineme… more

ASCOT data from the 1980 field measurement program in the Anderson Creek Valley, California. [ASCOT Program]

Description: With the ASCOT program's initial focus being on the study of transport and dispersion of materials injected in or near nocturnal drainage flows, a series of exploratory field experiments of limited scope were conducted during July 1979 in the Anderson Creek valley of The Geysers geothermal area in northern California. The analyses of the results provided insight into the structure of the drainage flows and permitted the design of a more comprehensive series of experiments that were conducted du… more

Instrumentation and control system for the AT-2 accelerator test stand

Description: A data-driven subroutine package, written for our accelerator test stand (ATS), is described. This flexible package permits the rapid writing and modifying of data acquisition, control, and analysis programs for the many diverse experiments performed on the ATS. These structurally simple and easy to maintain routines help to control administratively the integrity of the ATS through the use of the database. Our operating experience indicates that the original design goals have been met. We descr… more

Behavior of carbon-14 in waste packages for spent fuel in a repository in tuff. Revision 1

Description: Analysis of gas from a heated air-filled canister containing a spent fuel assembly before and after rupture of a fuel rod shows that about 1.5 mCi of {sup 14}C from the external surface of the assembly was rapidly oxidized and released as {sup 14}CO{sub 2} in excess oxygen at 275{sup 0}C and 10{sup 4}/sup rad/h. After rupture, an additional 0.3 mCi was released, probably also from the external surface. The total {sup 14}C inventory in the entire 15 x 15 rod assembly including structural hardwar… more
