Fuel conditioning facility inert gas filled reprocessing hot cell leak rate measurement

The cell leak rate is extremely small, less than 0.01 cfm, given the very large cell size. The oxygen concentration method is accurate to approximately ±0.002 cfm. The pressure-temperature method is accurate to about ±1 cfm. The pressure-temperature leak rate method can be used as a confirmation of the oxygen method results or as a backup if the oxygen monitors are not working.
