AbstractAbstract
[en] The in situ test method of iodine adsorbers used in France and Belgium has been developed by the French Atomic Energy Authority (CEA). Iodine 131 (in the form of elemental iodine or as methyl iodide) is injected in the ventilation duct up-stream to the adsorber; the filter decontamination factor (DF) is derived from up-stream and down-stream samplings. The main results obtained on Belgian plants are given considering two view points: acceptance of the installation and periodic testing. The results obtained are discussed in terms of: comparison of DF obtained by in situ and by laboratory measurements on activated carbon samples; effect of air flow rate and relative humidity of the air flow through the adsorber; determination of ventilation air flow from measurement of injected versus retained iodine as a possible cross check; and ageing of tested adsorbers
