(FR) REMPLISSAGE DESTINÉ À UN ÉVENT DE FILTRE ET DISPOSITIF D'ÉVENT DE FILTRE
(JA) フィルタベント用充填剤、及びフィルタベント装置
Abstract
(EN)
Provided are a filler for a filter vent, said filler being capable of more efficiently adsorbing radioactive iodine than conventional products and coping with severe accidents, and a filter vent device. The filler for a filter vent comprises granulated L-type zeolite, wherein: ion exchange sites in the L-type zeolite are at least partly substituted by silver; in the ion exchange sites, the composition ratio (a/b) of the silver-substituted ion exchange sites (a) to the ion exchange sites not substituted by silver (b) is set to 25/75-55/45; and the silver content is set to 7-12 wt% under dry conditions.

L'invention concerne un remplissage destiné à un évent de filtre, ledit remplissage étant capable d'adsorber l'iode radioactif de manière plus efficace que les produits classiques et de faire face à des accidents graves, et concerne également un dispositif d'évent de filtre. Le remplissage destiné à un évent de filtre comprend de la zéolite de type L en granulés. Des sites d'échange d'ions dans la zéolite de type L sont au moins en partie substitués par de l'argent ; dans les sites d'échange d'ions, le rapport de composition (a/b) entre les sites d'échange d'ions substitués par de l'argent (a) et les sites d'échange d'ions non substitués par de l'argent (b) est établi à 25/75-55/45 ; et la teneur en argent est établie à 7-12 % en poids dans des conditions sèches.
