Smith, D E

The use of annular fuel can provide an inherent safety shutdown mechanism during hypothetical LMFBR accidents by providing a pathway for molten fuel to be ejected from the active core region to the fission gas plenum. This effect can result in sufficient negative reactivity to shut down a reactor prior to fuel pin cladding failure during a transient overpower (TOP) accident. The whole-core reactivity consequences of internal fuel motion were studied in six cases to determine the effect of geometric design variations.
