Book Description
A tabulation of the spherical assemblies for which the transport of 14-MeV neutrons have been measured using pulsed sphere and time-of-flight techniques is presented. The description of the measurements and their comparison with the predictions of LLNL Monte Carlo calculations using the ENDL and ENDF (III to V versions) libraries can be found in the publications listed in the references.

Book Description
New measurements of the neutron and gamma-ray emission spectra from materials of interest to thermonuclear reactors with a 14 MeV neutron source were done during 1986 and 1987. These measurements characterized by better resolution than those reported in the Summary published in 1982, were performed using the pulsed sphere and time-of-flight techniques. The detector used in these measurements was a NE-213 cylinder, 5.08 cm in diameter by 5.08 cm thick. The new measurements include the following materials: Be, C, N, H2O, C2F4 (teflon), Al, Si, Ti, Fe, Cu, Ta, W, Au, Pb, 232Th, and 238U. For all these materials, both the neutron and gamma emission spectra were measured. A complete tabulation of all the measurements done under the Pulse Sphere Program is presented. 37 refs., 1 tab.

Book Description
In this paper two topics will be presented: (a) the integral measurements and calculations of gamma-ray and neutron emission spectra due to a source of 14 MeV neutrons from materials of interest to thermonuclear reactors and (b) an overview of the new multi-user accelerator facility being built at LLNL. Under (a), recent measurements of the gamma-ray and neutron leakage spectra from materials ranging from Be to 238U pulsed with 14 MeV neutrons are presented. The Monte Carlo calculational analysis using the codes TART and SANDYL with the ENDL and ENDF/B-V photon-neutron libraries is discussed. Under (b), details of the new multi-disciplinary laboratory centered around a 10 MV Van de Graaff with four ion sources and 19 experimental beam lines will be given. The experimental program to be carried out in this facility will be discussed. 19 refs., 4 figs., 2 tabs.

Book Description
Some countries have moved beyond the design and operation of nuclear electricity generating systems to confronting the issue of nuclear waste disposal, whole others are still committed to further nuclear facility construction. Volume 24 chronicles these key developments and examines nuclear reactor accidents at Chernobyl, Bhopal, and TMI. The text also analyzes current international knowledge of neutron interactions; deterministic methods based on mean values for assessing radiation distributions; practical applications of the TIBERE models to explicit computation of leakage terms in realistic reactor geometry; and a technique to deal with the issues of finance, risk assessment, and public perception.
