Role of statistical linearization in the solution of nonlinear stochastic equations

Description: The solution of a generalized Langevin equation is referred to as a stochastic process. If the external forcing function is Gaussian white noise, the forward Kolmogarov equation yields the transition probability density function. Nonlinear problems must be handled by approximation procedures e.g., perturbation theories, eigenfunction expansions, and nonlinear optimization procedures. After some comments on the first two of these, attention is directed to the third, and the method of statistical… more

Nuclear processes involved in electronuclear breeding

Description: The nuclear processes considered in a recent LLL assessment of electronuclear breeding of fissile material are described. The nuclear cross sections and neutron yields measured in the MTA program (1949-1954), and the nuclear cascade calculations carried out then and in more recent times are briefly described. The probable advantage of deuterons over protons as particles to be accelerated is mentioned, and the need for a series of experiments to determine the choice of particle, optimum accelera… more

Evaluation of beam-line components for use in a large neutral-beam injector

Description: A conceptual model of a neutral-beam injector was used to examine the effect of beam-line components on reactor performance. Criteria were established to optimize a reactor's reliability and minimize its cost.

Using Salton Sea geothermal brines for electrical power: a review of progress in chemistry and materials technology, 1976 status

Description: Geothermal energy development research at the Lawrence Livermore Laboratory through 1976 has been aimed at solving the problems associated with the use of high-temperature, high-salinity brines found in the Salton Sea Geothermal Field for their practical conversion to electrical energy. Specifically, part of the program has been oriented toward solving the problems of scale and solids deposition and corrosion of system components that are exposed to the highly mineralized brines. Brine acidific… more

Hearthfire design base for the high current low velocity rf linac

Description: The particle beam parameters needed for inertial fusion can be achieved with conventional accelerator technology if heavy ion machines attain the level of performance of the most intense high energy proton machines. Many of the problems posed by this goal pertain to the low energy portions of the accelerator system. In particular, the implied particle current in the rf linac is 10/sup 3/--10/sup 4/ times the values achieved with existing heavy ion machines. Much of this discrepancy is simply at… more

Calorimetric assay of reactor grade PuO{sub 2}

Description: This paper describes an experiment to estimate random and systematic errors in determining the effective specific power of plutonium. Precisons and accuracies comparable to coulometric assay were demonstrated for a wide range of plutonium isotopic compositions. Thus, calorimetric assay can provide an effective method for plutonium assay of materials in the nuclear fuel cycle.
