Improving to the neutron fluence rate monitor measurement system at the Advanced Test Reactor [Poster]

A pre-conceptual design was developed at INL for a Submersible ATR
Gamma Examination (SAGE) Scanner. The purpose of the SAGE
scanner is to replace the existing flux wire monitoring scanning station so
that higher resolution gamma-ray energy data can be obtained more
quickly and with reduced personnel radiation exposure. One fundamental
design constraint was the ability to measure both the activated Co/Al wire
and the activated Ni wire simultaneously. This is made possible using a
HPGe detector which can easily distinguish between the energies of the
associated gamma-rays.
The SAGE scanner will include a receiver for a sample-holding magazine
that is designed to accommodate scanning of all the existing FMWH
designs. Furthermore, the design of the magazine will provide guidance
to experimenters wishing to incorporate new FMWH designs. The
magazine will hold multiple FMWHs, enabling the ability to automatically
measure the activity from several holders in sequence; a dramatic
improvement over the existing system that can only measure one wire at
a time.
