Reactor Physics Design Calculations for the ACPR Upgrade.

摘要

This report describes the reactor physics calculations performed for the upgrade of the Annular Core Pulse Reactor (ACPR). The ACPR has been in operation since 1967 and has been used for a variety of simulation and reactor safety experiments involving both transient and steady-state operations. The limitation in performing such experiments in the ACPR has been the degree to which realistic reactor safety and nuclear effects simulation conditions could be created. The motivation for the ACPR Upgrade was to increase pulse and steady-state performance with a sufficiently harder neutron energy spectrum to allow a wider range of tests to be performed.
