The objective of the ACPR Upgrade is to arrive at a reactor modification which will provide an increased pulsed neutron fluence in the irradiation cavity without an increased degradation of the pulse duration. The upgraded reactor will also have an increased steady-state neutron flux. The original approach to the upgrade modification involved a two-region core concept. The inner region, surrounding the irradiation cavity, would consist of a high-heat-capacity fuel which would sustain a large fission energy deposition. The outer region would consist of a uranium-zirconium hydride fuel similar to the present ACPR fuel. This reactor modification will make use of the majority of the existing reactor structure. At the end of this reporting period the decision was made to go to a single region high-heat-capacity fuel core.
