Abstract
A neutron guide constituted by two superposed and separable tubular elements extends from the reactor core to the immediate vicinity of the bottom wall of the reactor vessel directly above a neutron detection chamber located outside the vessel. The upper element containing a neutron-emissive medium comprises a closed tube filled with inert gas and engaged coaxially with the lower element which is positioned within a support sleeve. The lower element is provided with another closed sleeve filled with inert gas and terminating near the internal surface of the bottom of the reactor vessel.
