Abstract
I - Special tests for improving the sensitivity of burst cartridge detection equipment in power reactors II - Scintillator purge-flow tests using aged gas in the B.C.D. /E.D.F. 2 Summary. - The first part of this report describes the tests carried out on fission product detectors by a process in which gas is continuously injected in front of the scintillator. Using this system, the background is reduced and perturbations caused by pneumatic switches on the prospecting circuits are eliminated. The quality of the signals thus obtained permits better processing of the data and thus leads to a possible improvement in the sensitivity of burst cartridge detection. The second part gives results of tests carried out with both fresh and aged gases, the economic advantage of the latter being that it permits recycling through the reactor. Reduction of the background is less pronounced but the advantage of the stable signals is conserved.
