Abstract

The Advanced Neutron Source reactor (ANS), a proposed Department of Energy research reactor currently undergoing conceptual design, will generate a thermal neutron flux approximating 10²⁰ m^-2-s^-1. The compact core necessary to produce this flux provides little space for the shim/safety control rods, which are located in the central annulus of the core. Without proper control rod drive design, the control rod drive magnets (which hold the control rod latch in a ready-to-scram position) may be unable to support the required load due to their restricted size. The force analysis performed on the control rod latch mechanism to determine the fraction of control rod weight transferred to the drive magnet is described. This information will be useful during latch, control rod drive, and magnet design
