GREATER CONFINEMENT DISPOSAL [6 records]

Record 1 1996-03-31

English

Subject field(s)
  • Atomic Physics
  • Nuclear Waste Materials
CONT

The Department of Energy... has been experimenting with disposal of high dose rate waste packages containing high specific activity wastes in cylindrical holes. This "Greater Confinement Disposal" method offers better shielding of workers and, in some cases, better protection of intruders due to deeper burial. Greater Confinement Disposal is being used at the Nevada Test Site....

OBS

"specific activity": The rate of decay or a radioactive sample per unit of sample weight; measured in curies per gram.

Key term(s)
  • high specific radioactivity waste
  • high specific nuclear activity waste
  • high mass nuclear activity waste
  • high mass radioactivity waste

French

Domaine(s)
  • Physique atomique
  • Déchets nucléaires
OBS

Les déchets radioactifs sont caractérisés par [...] la quantité des radioéléments [qu'ils contiennent) exprimée par leur activité en becquerels par unité de masse dite activité massique.

OBS

Le terme «activité spécifique» est très répandu dans l'usage. On le retrouve, entre autres, dans le LAROG 1982 vol. 1 page 97 (Grand Dictionnaire encyclopédique Larousse), dans AUTEC et dans les Techniques de l'ingénieur (vol. B8-II page B-3600-9). Cependant son emploi fait l'objet de critiques, notamment de la source ENUCL, et l'ISO et la CEI recommandent l'emploi de «activité massique». Voir cette fiche dans Termium.

Key term(s)
  • déchet d'activité nucléaire massique élevée
  • déchet d'activité radioactive massique élevée

Boreholes.... In the US, holes are being used to dispose of LLW that has high concentrations of gamma emitting nuclides or other long-lived nuclides. The method is often referred to as "greater confinement disposal" and is practiced at the Nevada Test Site... facilities. Since the holes are sometimes constructed by augering into the soil they are often referred to as "augered holes".
