Annular core pulse reactor upgrade. Quarterly report, October--December 1975
The object of the ACPR Upgrade is to arrive at a reactor modification which will provide an increased pulsed neutron fluence in the irradiation cavity without increasing the pulse duration. The upgraded reactor will also have an increased steady-state neutron flux. The approach to the upgrade modification involves a two-region core concept. The inner region, surrounding the irradiation cavity, consists of a high-heat capacity fuel which will sustain a large fission energy deposition. The outer region consists 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. Progress is summarized in the following task areas: (1) safety, documentation, and compliance; (2) core nuclear design; (3) console development; (4) mechanical design; (5) fuel element design; (6) primary fuel material studies; (7) secondary fuel material studies; (8) driver core fuel element; and (9) diagnostic system. A project schedule is included. (DG)
