Monte Carlo model for a thick target T(D,n)/sup 4/ He neutron source (open access)

Monte Carlo model for a thick target T(D,n)/sup 4/ He neutron source

A brief description is given of a calculational model developed to simulate a T(D,n)/sup 4/ He neutron source which is anisotropic in energy and intensity. The model also provides a means for including the time dependency of the neutron source. Although the model has been applied specifically to the Lawrence Livermore Laboratory ICT accelerator, the technique is general and can be applied to any similar neutron source.

LOFT CIS analysis 3''-DW-1-E inside containment penetration S-5C (open access)

LOFT CIS analysis 3''-DW-1-E inside containment penetration S-5C

A stress analysis was performed on the 3''-DW-1-E piping system inside containment penetration S-5C. Deadweight, thermal expansion, and seismic loads were considered. The results indicate that this piping will meet ASME Section III, Class 2 requirements.

Determination of continuous gamma-ray spectra over the energy range 0. 1 to 8 MeV. [RETECTUR code] (open access)

Determination of continuous gamma-ray spectra over the energy range 0. 1 to 8 MeV. [RETECTUR code]

An experimental facility was established at LLL to characterize radiation fields produced by a variety of sources and transmitted through various shielding materials. Specific techniques for acquiring and reducing continuous gamma-ray energy spectra are discussed including NaI(Tl) detectors. Use of several detector sizes allowed study of a wide variety of source intensities and calculation of response matrices for a number of collimated detector configurations. A computer program to perform the data reduction by an iterative unfolding process is described. The reduction technique discloses the continuous gamma-ray energy spectrum over the range 0.1 to 8 MeV as opposed to the traditional peak intensity analysis. 11 references.

Magnetic fusion energy annual report, July 1975--September 1976 (open access)

Magnetic fusion energy annual report, July 1975--September 1976

Supporting research activities continued to provide the technical basis for future mirror-confinement experiments. The industrial development of a high-current, high-field, high-current-density Nb/sub 3/Sn conductor was the main goal of the superconducting magnet program. Beam direct conversion was being developed as a means of raising the efficiency of neutral-beam production, and plasma direct conversion was shown to work as predicted. Conceptual designs were completed for various types of power reactors. The neutral-beam program progressed in three areas: experimental work, facility construction, and conceptual design. Experiments on the 14-MeV Rotating Target Neutron Source (RTNS-II) included participation by experimenters from many different institutions. Methods for processing tritium-contaminated wastes were pursued, as were studies of tritiated methane in stainless-steel vessels, the control of tritium in mirror fusion reactors, and the development of titanium tritide targets for the RTNS. The report period witnessed a rapid maturation in ability to describe theoretically the behavior of ion-cyclotron noise in the 2XIIB and the influence of that noise on the confined plasma. The high beta values achieved in 2XIIB prompted much theoretical analysis of the properties of high-beta equilibria and stability, including those of a field-reversed state. Excellent progress was made on the development of computer codes applicable …
