  • Waste Management

CONT

... the concept of deep geological disposal in stable rock formations is a fully acceptable method of disposing permanently of high-level radioactive wastes from the nuclear fuel cycle.

OBS

... the Federal Republic of Germany has chosen the policy that all radioactive waste will be placed in deep geological formations. The Asse salt mine, located in a salt diapir in Lower Saxony, has served as the national R&D facility on disposal of all types of radioactive waste.

OBS

Of the various disposal concepts which have been suggested for LLW, only three were compatible with the geological characteristics of the CRNL property : burial in excavated sand trenches... ;containment in an engineered below-ground vault; and emplacement in a shallow mined cavity in rock.

OBS

Emplacement of wastes in abandoned mines.

Domaine(s)
  • Gestion des déchets

CONT

Déchets à vie longue : le stockage en formation géologique. [...] la solution retenue est l'enfouissement à grande profondeur, quelques centaines de mètres, dans des formations géologiques choisies pour leur nature et leur configuration favorables à la maîtrise des transferts.

CONT

La tâche A4 «Recherches sur le stockage géologique profond et le stockage au voisinage de la surface» ne peut être conceptuellement séparée de la réalisation et l'exploitation des installations expérimentales souterraines [...]

OBS

On réserve normalement le terme «évacuation» pour désigner le stockage définitif.

Subject field(s)
  • Waste Management

  • Compartment - Canadian Nuclear Safety Commission
CONT

A number of disposal methods for nuclear fuel wastes have been suggested internationally, including ejection of the waste into outer space; transmutation of the radioactive elements; emplacement in a polar ice cap; and burial within various geological formations, both on the continents and beneath the sea floor.

CONT

Of the various disposal concepts which have been suggested for LLW, only three were compatible with the geological characteristics of the CRNL property : burial in excavated sand trenches with minor engineered features to inhibit nuclide migration, containment in an engineered below-ground vault; and emplacement in a shallow mined cavity rock.

CONT

Plusieurs méthodes d'évacuation des déchets de combustible nucléaire ont été suggérées à travers le monde, y compris le lancement des déchets dans l'espace, la transmutation des éléments radioactifs, le dépôt sous la calotte polaire et l'enfouissement à l'intérieur de diverses formations géologiques, soit sous terre, soit sous les fonds marins.

CONT

Des stockages par enfouissement à faible profondeur sont réalisés aux États-Unis, en Grande-Bretagne, en U.R.S.S., au Canada et en France. Dans les deux premiers pays, le stockage se fait sur des déchets pas ou peu conditionnés, dans des tranchées en pleine terre.

Of the various disposal concepts which have been suggested for low-level wastes, only three were compatible with the geological characteristics of the CRNL property : burial in excavated sand trenches with minor engineered features to inhibit nuclide migration; containment in an engineered below-ground vault; and emplacement in a shallow mined cavity in rock.

CONT

Mined caverns. Rock cavities can provide a high degree of containment and isolation for waste if suitable geologic conditions are present. ... Preferred characteristics of the host rock are: low frequency of open fractures to restrict groundwater flows, definable structure so that uncertainties in advance of excavation are low, and good rock competence so that adequately sized chambers can be excavated safely.

Geological disposal .... Five ... countries have selected granite formations for the underground disposal vaults, one a volcanic tuff formation, one a salt formation, and one a clay formation. The other countries are studying disposal in granite, salt, clay, and sedimentary rock.

[...] une attention toute particulière est portée sur les mécanismes d'altération en conditions réalistes de stockage géologique, c'est-à-dire avec mise en jeu de paramètres importants tels que la température, la pression, la nature de la roche d'accueil, celle du matériau de remplissage ou bien celle des eaux souterraines par exemple.

CONT

La vitrification est choisie pour les déchets de haute activité qui seront ultérieurement envoyés vers des stockages géologiques.

CONT

[...] déchets justiciables de l'évacuation en formation géologique terrestre.

CONT

L'enfouissement sous les fonds des océans. Il ne s'agit pas d'une immersion de déchets mais d'un stockage en formation géologique, formation de type particulier puisque subocéanique. [...] Cette méthode combine les avantages du stockage dans les formations argileuses à celui de l'immersion dans les fosses océaniques profondes [...].

OBS

Le terme anglais "disposal" (en français : "évacuation") désigne tout particulièrement le stockage permanent. Voir "disposal" et "permanent disposal" dans TERMIUM.

In the below-ground vault option, the major characteristics are that :-wastes are placed below grade in a reinforced-concrete vault in a suitable hydrogeological site;-the vault is covered with a thick concrete roof, covered in turn by a thick layer of earth;-structural stability is provided by the facility itself;-the voids between the waste packages may be filled with sand or the wastes may be compacted by heavy equipment and-no additional engineered barriers are required.

[Enfouissement à faible profondeur]. Ce stockage est réalisé soit sur des aires aménagées, soit dans des tranchées bétonnées. [...] Les tranchées bétonnées sont réalisées en partant d'une fosse creusée dans le sol, dans laquelle est réalisé un radier. On élève des parois en béton le long de la fosse, constituant ainsi des cases dans lesquelles sont déposés les déchets après injection d'un coulis de ciment, on obtient un monolithe que l'on recouvre par une couche bitumineuse. Chaque case a comme dimensions 4,5 m X 4,5 m X 4 m.
