Abstract:
(EN) Provided is a method for treating a radioactive waste liquid containing radioactive cesium and radioactive strontium. In the method, a radioactive waste liquid containing radioactive cesium and radioactive strontium is passed through, at a linear flow rate (LV) of 1-40 m/h and a space velocity (SV) of 200 h-1 or less, an adsorption column filled to a bed height of 10-300 cm with an adsorbent material so as to adsorb the radioactive cesium and the radioactive strontium onto the adsorbent material. The adsorbent material is particulate with a particle diameter of 250-1200 µm and is a cesium or strontium adsorbent material which contains a crystalline silicotitanate represented by general formula A4Ti4Si3O16·nH2O (in the formula, A denotes Na, K or a combination thereof and n denotes a number between 0 and 8), which has a crystallite diameter of 60 Å or more and a half-value width at a diffraction peak of the lattice plane (100 plane) of 0.9° or less.
(FR) L'invention concerne un procédé de traitement de déchets liquides radioactifs contenant du césium radioactif et du strontium radioactif. Dans le procédé, un déchet liquide radioactif contenant du césium radioactif et du strontium radioactif est fait passer à travers, à un débit linéaire (LV) de 1 à 40 m/h et une vitesse spatiale (SV) de 200 h-1 ou moins, une colonne d'adsorption remplie jusqu'à une hauteur de lit de 10 à 300 cm d'un matériau adsorbant afin d'adsorber le césium radioactif et le strontium radioactif sur le matériau adsorbant. Le matériau adsorbant est particulaire présentant une granulométrie de 250 à 1200 µm et est un matériau adsorbant du césium ou du strontium qui contient un silicotitanate cristallin représenté par la formule générale A4Ti4Si3O16·nH2O (dans la formule, A représente Na, K, ou une combinaison de ces dernière et n représente un nombre entre 0 et 8), qui a un diamètre de cristallite de 60 Å ou plus et une largeur à mi-hauteur à un pic de diffraction du plan réticulaire (plan 100) de 0,9° ou moins.
(JA) 結晶子径が60Å以上で、且つ格子面(100面)における回折ピークの半値幅が0.9゜以下である一般式:ATiSi16・nHO(式中、AはNa又はK又はこれらの組み合わせであり、nは0~8の数を示す。)で表される結晶性シリコチタネートを含む、セシウム又はストロンチウムの吸着材であって、粒径250μm以上1200μm以下の粒子状の吸着材を10cm以上300cm以下の層高で充填した吸着塔に、放射性セシウム及び放射性ストロンチウムを含有する放射性廃液を通水線流速(LV)1m/h以上40m/h以下、空間速度(SV)200h-1以下で通水して、当該吸着材に放射性セシウム及び放射性ストロンチウムを吸着させることを含む、放射性セシウム及び放射性ストロンチウムを含有する放射性廃液の処理方法。
