Zusammenfassung:1,037,148. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 4, 1965 [Feb. 7, 1964], No. 4947/65. Heading G6C. A nuclear reactor burst fuel-can detector system employs boron-trifluoride detectors, each of which is mounted at the centre of a group of sampling tubes. The tubes may be switched in sequence so as to isolate a defective channel through a continuously operating further monitor, when the radio-activity of the group is above normal. In addition a signal is developed to represent the power-variation of a group of channels. This signal incorporates parameters corresponding to the total reactivity in all the channels at the time of measurement and at a reference instant. The power variation signal controls an alarm system.
