Title: Modeling of partial flooding for criticality safety analysis

Abstract

Accidental exposure of fuel to water is often an important concern in criticality safety. This is the result of the effectiveness of water as a reflecting material and especially as a neutron moderating material. Even a low effective water density, such as that produced by fire protection sprinklers, is sometimes sufficient to produce a large reactivity increase relative to dry fuel. Also, the peak reactivity can occur when the water exposure is far below the maximum possible. For these reasons, it is necessary to consider all plausible water exposure possibilities when assessing the criticality safety of fuel. This paper explores approaches for modeling the partial flooding of stored fuel.
