Abstract: A neutron flux monitoring system is described for a nuclear reactor which enables the monitoring of very low levels of neutron flux such as may exist during the shutdown condition of the reactor. The pulses produced in the flux detectors distributed around the reactor core and ordinarily used for power range monitoring are conveyed, by isolation means, to summing means which provide a count rate output corresponding to the total number of pulses produced by all of the neutron flux detectors.

Abstract: A fisherman's leader caddy consisting of an elongated cylindrical plastic tube having a flange at either end. The flanges are provided with recesses for mounting fishing hooks. A plurality of equally spaced rows of carbon steel leader hooks are disposed around the perimeter of the leader caddy tube with some hooks pointed towards one end of the caddy tube, and the remaining caddy hooks pointing towards the other end of the caddy tube. During transportation and storage of multiple leader fishing tackle, the fishing hook is mounted within either flange, and the eye ends of the plural leaders are connected by resilient fasteners, such as rubber bands, to any of the caddy hooks, thereby maintaining the leaders taut and free of entanglement.

Abstract: An electrical cable is described wherein an inner conductor having one or more layers of radiation resistant organic insulation extends through a metal sleeve which is larger than the insulation to leave a space capable of accommodating thermal expansion of the insulation layer or layers and which may be filled with a non-reacting gas. Also described are a method for connecting such a cable, and a radiation sensor and cable assembly incorporating such a cable.
