  • Abstract
    To aid in the design of LMFBR safety test experiments and safety test faciities (STF), a program of evaluation of concepts for fuel-motion diagnostics instrumentation has been undertaken. A part of this evaluation is being done at PARKA, a Rover project critical assembly which has been modified to study the self nuclear image from driven FTR-type fuel assemblies. Feasibility of obtaining fast-neutron images of single-pin voids in assemblies of up to 127 fuel pins has been demonstrated, albeit marginally for the larger fuel bundles. The feasibility of using in-core detectors as fuel-motion monitors has also been studied. Use of PARKA in a pulsed mode to study STF transient phenomena is discussed.
