Harrison, D

Equipment developed to obtain reactivity change information for the Dounreay Fast Reactor is described. The technique of steady-state analysis was adopted. A sinusoidal perturbation of reactivity is applied to the reactor by means of a rods formed of one half cylinder of absorber material (B/sup 10/), which extends into the reactor core and is rotated about the cylinder axis at an angular velocity corresponding to that at which the measurement is to be made. The measured response will be that of the neutron fiuxs and the sensing device is an ion chamber. The basic circuit requirements are listed. The modulating- device is a carrier system with a magslip element. Chopper stabilized d-c computer type amplifiers are used for the ion chamber currents the recorder outputs and the in-phase and quadrature channel amplifiers. The a-c amplifier is of conventional design and makes use of transformer coupling into the synchro- resolver. This equipment together with stabilized power supplies and certain relay and servo circuits will be housed in two standard 6 ft P.O. type racks within the Dounreay sphere. (M.H.R.)
