Research and development of a helium-4 based solar neutrino detector

Description: In this report we describe results of experiments to detect low energy radiation in superfluid helium. The ultimate aim of this research is to establish the feasibility of this technique for use in detecting neutrinos from the p-p and Be-7 reactions in the sun. In these experiments we have seen the first detection of 5.5 MeV {alpha} particles via evaporation from a bath of superfluid helium. An {alpha} particle excites phonons and rotons in the liquid helium, and these excitations are sufficien… more

Effects of whole-body. gamma. -irradiation on the biosynthesis of certain serum proteins. Final report, November 29, 1967--June 30, 1976. [Rats]

Description: Whole-body exposure of rats to ionizing radiations yielded an increased incorporation of labeled amino acids into serum albumin in in vivo studies suggesting a stimulation of biosynthesis. Actually this may have been caused by an elevated hepatic transport of labeled amino acids (see below). A suppressed biosynthesis of albumin was observed when the experiments were performed in vitro using liver microsomes. Impaired biosynthesis appeared to be caused by a reduced mRNA production. Irradiation s… more

Geothermal energy in California: Status report

Description: The potential for electric energy from geothermal resources in California is currently estimated to be equivalent to the output from 14 to 21 large (1000 MW) central station power plants. In addition, since over 30 California cities are located near potential geothermal resources, the non-electric applications of geothermal heat (industrial, agriculture, space heating, etc.) could be enormous. Therefore, the full-scale utilization of geothermal resources would have a major impact upon the energ… more

Solar energy as an alternate energy source to mixed oxide fuels in light-water cooled reactors

Description: Supplemental information pertaining to the generic environmental impact statement on the Pu recycling process for mixed oxide light-water cooled reactors (GESMO) was requested from several sources. In particular, the role of alternate sources of energy was to be explored and the implications of these alternate sources to the question of Pu recycle in LWRs were to be investigated. In this vein, solar energy as an alternate source is the main subject of this report, along with other information r… more

Advisability of seismic scram

Description: The study assesses the value of seismic trip (scram) systems on commercial nuclear power plants. Five topics were specifically addressed: (1) the likelihood that existing instrumentation would trip the plant; (2) the consequences of spurious trips; (3) the consequences of tripping during an earthquake; (4) the advantages of a controlled shutdown; and (5) the desirability of continuing operation. A comparative risk assessment was made based on evaluation of fault trees constructed for plants wit… more

The 75As(n,2n) Cross Sections into the 74As Isomer and Ground State

Description: The {sup 75}As(n, 2n) cross section for the population of the T{sub 1/2} = 26.8-ns isomer at E{sub x} = 259.3 keV in {sup 74}As has been measured as a function of incident neutron energy, from threshold to E{sub n} = 20 MeV. The cross section was measured using the GEANIE spectrometer at LANSCE/WNR. For convenience, the {sup 75}As(n, 2n) population cross section for the {sup 74}As ground state has been deduced as the difference between the previously-known (n, 2n) reaction cross section and the… more

High-Efficiency Steam Electrolyzer

Description: A hydrogen economy will require readily available and affordable hydrogen fuel. Current methods of hydrogen production do not fulfill these requirements. We are working on an electrolyzer system that can provide distributed hydrogen production while taking advantage of the nation's existing natural gas infrastructure. Electrolysis is a promising hydrogen production technology both because of its ability to produce pure hydrogen from water and because it does not require large, centralized plant… more
