Abstract
Abstract A burst cartridge detection system for use with gas-cooled power reactors includes a pressure vessel having a sampling chamber with an electrode positioned within the chamber for preventing the build-up of daughter products within the chamber. Two filters and a delay line are in fluid communication with the chamber, and a collimator whereby predetermined types of radiation within the coolant gas, such as gammas form fission products within the reactor, are detected.
