Radionuclide limits for vault disposal at the Savannah River Site

The Savannah River Site is developing a facility called the E-Area Vaults which will serve as the new radioactive waste disposal facility beginning early in 1992. The facility will employ engineered below-grade concrete vaults for disposal and above-grade storage for certain long-lived mobile radionuclides. This report documents the determination of interim upper limits for radionuclide inventories and concentrations which should be allowed in the disposal structures. The work presented here will aid in the development of both waste acceptance criteria and operating limits for the E-Area Vaults. Disposal limits for forty isotopes which comprise the SRS waste streams were determined. The limits are based on total facility and vault inventories for those radionuclides which impact groundwater, and or waste package concentrations for those radionuclides which could affect intruders.

Texas Register, Volume 17, Number 9, Pages 883-967, February 4, 1992

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

EC Vacuum Vessel Finite Element Analysis (open access)

EC Vacuum Vessel Finite Element Analysis

This Note contains a summary of the results of the finite element analysis of the EC Cryostat vacuum vessel performed by Dave Rudland in 1987. The results are used in the structural evaluation of the EC cryostats presented in Engineering Note 194. It should also be noted that the adequacy of the design of the vacuum vessels was reviewed and verified by the Battelle Memorial Institute. Battelle used a shell of revolution program to essentially duplicate the FEA analysis with similar results. It should be noted that no plots of the finite element mesh were retained from the analysis, and these can not be easily reproduced due to a change in the version of the ANSYS computer program shortly after the analysis was completed.

Anomalous variation of the normal state resistance of {kappa}-(BEDT-TTF){sub 2}CuN(CN){sub 2}Br with temperature and hydrostatic pressure. Small polaron (open access)

Anomalous variation of the normal state resistance of {kappa}-(BEDT-TTF){sub 2}CuN(CN){sub 2}Br with temperature and hydrostatic pressure. Small polaron

Several radical organic cation conductors have resistances, R(T)`s which attain maxima as functions of temperature. In some cases, {kappa}-(BEDT-TTF){sub 2}CuN(CN){sub 2}Br for instance [Sushko et al., J. Phys. I. France, 1 (1991) 1375], the maxima are suppressed by hydrostatic pressure, and with sufficient pressure R(T) becomes classified as metallic in the sense that dR/dT > 0. These variations with temperature and pressure can be understood quantitatively in terms of two equivalent models: (a) one in which the electronic density of states g({epsilon}) is constant except that it is zero for E{sub f}{le}{epsilon}{le}E{sub g} and (b) the small polaron. The effect of pressure in this case is essentially to oxidize some cation or anion.
