Janner, K

A neutron flux sensing gage for measuring and continuously controlling the neutron flux of a reactor is described. The gage consists of a neutron flux detector and a composite jacket structure enclosing the detector and comprising three layers, the innermost layer consists of a moderator substance of great diffusion length, the intermediate layer consists of reflector substance of small diffusion length, and the outermost layer consists of a neutron absorber. The neutron flux measuring gage is mounted on a gamma radiation absorber plate which in turn is mounted on the reactor vessel. There is a reflector mounted on the inner wall of the vessel which forms a neutron permeable vacancy behind the gamma absorber plate. (N.W.R.)
