Substitute safety rods: Physics of operation and irradiation
Under certain assumed accidents, an SRS reactor may lose most of its bulk moderator while maintaining flow to fuel assemblies. If this occurs immediately after operation at power, components normally dependent on convective heat transfer to the moderator will heat up with the possibility of melting that component. One component at risk is the currently used cadmium safety rod. A substitute safety rod consisting solely of sintered B{sub 4}C and stainless steel has been designed which is capable of withstanding much higher temperatures. This memorandum provides the physics basis for the adequacy of the rod for reactor shutdown and provides a set of criteria for acceptance in the NTG tests. This memorandum provides physics data for other aspects of operation. These include: Heat production and helium production, along with related phenomena, resulting from inadvertent irradiation at power. Gamma heat input under drained tank conditions. An equivalent rod design suitable for charge design and safety analyses. Degradation under normal operation. Thermal flux ripple in adjacent fuel due to axial striping of alternate B{sub 4}C and steel pellets. Possible effect on safety analyses. Safety rod withdrawal during reactor startup.

A new transport discretization scheme for arbitrary spatial meshes in XY geometry
We introduce a new spatial discretization scheme for transport on arbitrary spatial grids in XY geometry. Our arbitrary'' spatial grid is composed of arbitrarily-connected polygons, each of which may have an arbitrary number of sides. We begin our derivation by imposing particle balance on every corner'' of each cell (Consequently, we call our scheme the corner-balance (CB) method.) We complete the derivation by introducing simple closure formulas that relate volume-averaged unknowns to surface-averaged unknowns in each corner. We discuss the relationship of the new scheme to discontinuous finite-element methods and to multiple-balance methods. We demonstrate that on simple grids, the method reduces to very robust schemes that have been studied previously. We discuss the theoretical performance of the method in the thick diffusion limit, and provide numerical results for that limit. We present additional numerical results from simple problems that test the new scheme in other limits. Finally, we offer some concluding remarks about the method. 9 refs., 6 figs.

Optically-ionized plasma recombination x-ray lasers
Design studies for recombination x-ray lasers based on plasmas ionized by high intensity, short pulse optical lasers are presented. Transient lasing on n = 3 to n = 2 transitions in Lithium-like Neon allows for moderately short wavelengths ({le} 100{angstrom}) without requiring ionizing intensities associated with relativistic electron quiver energies. The electron energy distribution following the ionizing pulse affects directly the predicted gains for this resonance transition. Efficiencies of 10{sup {minus}6} or greater are found for plasma temperatures in the vicinity of 40 eV. Simulation studies of parametric heating phenomena relating to stimulated Raman and Compton scattering are presented. For electron densities less than about 2.5 {times} 10{sup 20} cm{sup {minus}3} and peak driver intensity of 2 {times} 10{sup 17} W/cm{sup 2} at 0.25 {mu}m with pulse length of 100 fsec, the amount of electron heating is found to be marginally significant. For Lithium-like Aluminum, the required relativistic ionizing intensity gives excessive electron heating and reduced efficiency, thereby rendering this scheme impractical for generating shorter wavelength lasing ({le} 50{angstrom}) in the transient case. Following the transient lasing phase, a slow hydrodynamic expansion into the surrounding cool plasma is accompanied by quasi-static gain on the n = 4 to n = …

Evaluation of the computerized utilities energy monitoring and control system installed at the US Military Community at Goeppingen, Germany
Under the provisions of an Interagency Agreement between the US Army and the Department of Energy, Martin Marietta Energy Systems, Inc., through the Oak Ridge National Laboratory, is evaluating the Utilities and Energy Monitoring and Control System (UEMCS) installed at the US Military Community Activity at Goeppingen, Germany. This evaluation relies on examination of existing data and information to determine the effectiveness of the UEMCS. The Goeppingen UEMCS is an integral part of a combined UEMCS/district heating system which includes the UEMCS at Schwaebisch Gmuend, Germany. The system was installed during 1985 and 1986. The UEMCS at Goeppingen and Schwaebisch Gmuend are both well designed, implemented, and maintained. The UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS at Schwaebisch Gmuend does not have a central computer, but requires only a dedicated phone line to couple with the one at Goeppingen. Though the conversion to district heat has produced the majority of energy savings, the UEMCS day/night setback program also contributes substantially, with additional savings from start/stop programs, such as seasonal switchover, and various temperature control …

Investigations of charge-separation processes in metal complexes
The major thrust of the research has been the quantification of the excited states of inorganic complexes that display potential for mediating charge-separation processes. Investigations of copper(1) mixed-ligand complexes have been completed. Non-equilibrated emitting states have been assigned. Chemical tuning of the emission energy by modifying the basicity of the donor ligand on the metal has been achieved. Structure-property relationships have been defined for crystalline complexes of zinc containing both diimine and monothiol ligands. Correlation of the spectral shifts with the rotations of the thiol phenyl rings in different crystal phases has been shown by comparing with extended Huckel calculations and x-ray structures. Complexes of zinc containing diimine and dithiol ligands are shown to be polynuclear species. A trinuclear species can be forced to assume a binuclear structure by incorporating other non-coordinating ligands into the lattice. The transformation is accompanied by substantial photophysical changes. Syntheses and x-ray structure determinations of platinum(2) complexes containing diimine ligands only, both diimine and dithiol ligands, and dithiol ligands only have been completed. An unusual platinum(3) bis(dithiol) species has been obtained and its structure determined. Investigations of the emission spectra of bis(bipyridine)platinum(2) have revealed the existence of multiple emitting states with both ligand-localized and charge- …

The enriched chromium neutrino source for GALLEX
The preparation and study of an intense source of neutrinos in the form of neutron irradiated materials which are enriched in Cr-50 for use in the GALLEX solar neutrino experiment are discussed. Chromyl fluoride gas is enriched in the Cr-50 isotope by gas centrifugation and subsequently converted to a very stable form of chromium oxide. The results of neutron activation analyses of such chromium samples indicate low levels of any long-lived activities, but show that short-lived activities, in particular Na-24, may be of concern. These results show that irradiating chromium oxide enriched in Cr-50 is preferable to irradiating either natural chromium or argon gas as a means of producing a neutrino source to calibrate the GALLEX detector. These results of the impurity level analysis of the enriched chromyl fluoride gas and its conversion to the oxide are also of interest to work in progress by other members of the Collaboration investigating an alternative conversion of the enriched gas to chromium metal. 35 refs., 12 figs., 5 tabs.
