The design criteria and operation of seven nuclear instrumentation channels and safety interlocks employed for initial measurements on heavy-water moderated thoria-urania lattices of interest to power reactors are described. The mechanical design features of the various control mechanisms and components are illustrated or described briefly where necessary to clarify the over-all instrument-control scheme. The basic startup sequence is given.
