IMPROVEMENTS IN FISSION PRODUCT DETECTION SYSTEMS
Patent
·
OSTI ID:4208674
A fuel element rupture detection system is described which is based on detection of the solids from gaseous fission product decay. Decay solids are precipitated from the coolant gas on a negative electrode by a radial electrostatic field. The electrode is withdrawn at suitable intervals to a counting chamber. A shielded proportional counter here measures beta activity of the electrode and alternately of an extension of the electrode. The difference of these measurements represents solid fission product activity. (T.R.H.)
