Topical report on a preconceptual design for the Spallation-Induced Lithium Conversion (SILC) target for the accelerator production of tritium (APT)

Abstract

The preconceptual design of the APT Li-A1 target system, also referred to as the Spallation-Induced Lithium Conversion (SILC), target system, is summarized in this report. The. system has been designed to producea "3./8 G9al '' quantit3t of tritium,using the 2.00-mA, 1.0: GeV pr(Jton beam emerging from the LANL-designed LINAC. The SILC target system consists of a beam expander, a heavy-water-cooled lead spallation neutron source assembly surrounded by light-water-cooled Li-A1 blankets, a target window, heat removal systems, and related safety systems. The preconceptual design of each of these major components is described. Descriptions are also provided for the target fabrication, tritium extraction, and waste-steam processes. Performance characteristics are presented and discussed.

The ADAPT concept—an accelerator driven system for the rapid and efficient disposal of plutonium

“…shows the overall layout of ADAPT. The linear accelerator (linac) and target systems for ADAPT are similar in design and operating parameters to the systems developed for the APT concept [1] to produce tritium. The linac delivers a proton current on the order of 100 milliamps at 1 Gev (= 109ev)onto the D20 cooled lead target.…”
