Assessment of beam tube performance for the MAPLE research reactor.

Abstract

The MAPLE research reactor is a versatile new research facility that can be adapted to meet the requirements of a variety of reactor applications. A particular group of reactor applications involve the use of beams of radiation extracted from the reactor core via tubes that penetrate through the biological shield and terminate in the reflector surrounding the fuelled core. An assessment of the neutron and gamma radiation fields entering beam tubes that are located radially or tangentially with respect to the core is given.
