A method for assessing the effect of sprinkler water on the reactivity of storage arrays of fissile material

Creators

Description

A model is developed that performs screening calculations to assess the reactivity added by sprinkler water in an air-spaced, storage array of fissile material that is surrounded by a water reflector. The purpose of the model is the expand the type of guidance given in ANSI/ANS-8.7, ''Guide for Nuclear Criticality Safety in the Storage of Fissile Materials.'' The dimensions and densities of the storage vault with sprinkler water are changed with the constant optical thickness transformation to an equivalent system with water at a density of 1 g/cc surrounded by a superdense reflector. The validity of the model is demonstrated by comparison with Monte Carlo calculations made with KENO V.a on storage arrays of 93.2 wt % 235U metal
