After the depleted fuel assemblies are removed from the reactor, they are placed in a canister … The canister alone, however, is not sufficient to provide adequate gamma or neutron radiation shielding. Therefore, apparatus that provide additional radiation shielding are required during transport, preparation and subsequent dry storage … The additional shielding is achieved by placing the canisters within large cylindrical containers called casks. Casks are typically designed to shield the environment from the dangerous radiation in two ways. First, shielding of gamma radiation requires large amounts of mass. Gamma rays are best absorbed by materials with a high atomic number and a high density, such as concrete, lead, and steel. The greater the density and thickness of the blocking material, the better the absorption/shielding of the gamma radiation. 1, record 2, English, - blocking%20material

Le conditionnement des matières radioactives. Le conditionnement est un processus industriel qui met en œuvre :-un matériau de blocage qui immobilise les déchets. Ce matériau constitue la matrice-une(ou plusieurs) enveloppe(s), dans laquelle(lesquelles) les déchets immobilisés sont placés, facilitant ainsi principalement la manutention. L'ensemble est appelé colis. 2, record 2, French, - mat%C3%A9riau%20de%20blocage

Record number: 3, Textual support number: 1 CONT
L’immobilisation a pour but de fixer le déchet sous une forme solide et stable, qui réduise au minimum la possibilité de migration et de dispersion des radionucléides. Elle consiste en un enrobage des déchets dans une matière [p. ex. : bitume, ciment, céramiques, polymères] qui les fixent en un bloc compact, la matrice d’enrobage. 3, record 3, French, - matrice%20d%27enrobage

C’est l’association des propriétés cumulées du déchet, de sa matrice d’enrobage ou de blocage et, dans certaines conditions, de l’enveloppe des colis et des éléments constitutifs des modules de stockage (plates-formes et alvéoles), qui constitue le premier système de barrières d’isolement des déchets. 2, record 3, French, - matrice%20d%27enrobage

Le choix du bitume comme matrice de conditionnement a été conduit par la prise en considération des nombreux avantages présentés par ce matériau : - excellente adhésivité à de multiples supports, - solubilité négligeable dans l’eau et imperméabilité, plasticité, élasticité, résistance aux chocs, - tenue à l’irradiation satisfaisante, - inertie chimique, - bonne tenue biologique, - matière première abondante, coûts modérés. Il existe cependant quelques inconvénients attachés à cette matrice : inflammabilité des hydrocarbures lourds, mauvais coefficient de transfert de la chaleur, difficulté de la modélisation de son comportement à long terme. 3, record 3, French, - matrice%20d%27enrobage

Conditionnement dans le béton. [...] cette méthode [...] est adaptée à la solidification des principaux déchets de faible et moyenne activités. Outre le ciment et l’apport d’eau nécessaire à sa prise, certains additifs sont ajoutés pour améliorer la qualité de la matrice [...] ou pour diminuer la quantité de ciment à utiliser [...]. 7, record 3, French, - matrice%20d%27enrobage
Record number: 3, Textual support number: 2 OBS
Dans les ouvrages de langue française, on parle de «matrice d’enrobage» et non de «matrice de solidification». Quant à «matrice de conditionnement», c’est un terme générique mais qui peut aussi être utilisé. 8, record 3, French, - matrice%20d%27enrobage
