Modeling Small Pebble Bed Reactor Fuel Loading Concepts with PEBBED

摘要

Pebble bed high temperature reactors require a refueling system unlike any other reactor; one which offers a degree of flexibility in operation that may be suitable for, among other industrial applications, remote deployment of small (＜250MWt) power supplies. Along with the basic neutronic characteristics of graphite-moderated cores with coated particle fuel, the refueling system also produces unique neutronic features which require equally specialized modeling tools.
