CONT

... the evidence suggests that a deep geological repository for nuclear fuel wastes in hard crystalline rock would not be breached by the erosional effects of glaciation, although the regional groundwater flow system would likely be modified.

CONT

Du fait de leur solidité ou de leur résistance, les roches cristallines possèdent les qualités voulues pour réaliser des ouvrages de stockage de grande dimension [...]. Les cavités expérimentales construites pour étudier les problèmes de stockage des déchets radioactifs ont apporté la confirmation de ce fait, et ont même permis d'affiner les modèles décrivant le comportement thermique et mécanique des roches.

CONT

Il semble évident [...] qu'un dépôt de combustibles nucléaires dans des couches géologiques profondes de roches cristallines dures ne serait pas endommagé par l'érosion de la glaciation, bien que le système de débit des eaux souterraines régionales serait sans doute modifié.

CONT

[...] on peut envisager la possibilité de créer un stockage dans différentes roches : - roches sédimentaires telles que l'argile et le sel; - roches cristallines telles que le granite et le schiste.

Record 2 2003-12-22

English

Subject field(s)
  • Spacecraft
CONT

... The Progress supply vehicle to the ISS [International Space Station] is an automated version of the Soyuz, and was developed to carry propellant and cargo to the Salyut and Mir space station. It will serve the same purpose for the ISS. Although the ISS has its own propulsion system, generally it is the Progress vehicle that will perform periodic reboost maneuvers to maintain the ISS orbital altitude. The Progress is approximately the same size as the Soyuz, but it has a slightly higher mass at launch of approximately 7150 kg. The Progress spacecraft docks automatically to the ISS, and the TORU [Teleoperated Control System-Manual Docking System on Zarya] system acts as a backup remote control docking system. Progress is composed of three modules : the Cargo Module, the Refueling Module, and the Instrument/Propulsion Module. A modified version of the Progress M, called the Progress M1, is planned for operation with the ISS. This version will have more propellant tanks for refueling, as the entire Refueling Module is devoted to fuel. Water will be carried in the Cargo Module. The Progress payload includes cargo in the pressurized Cargo Module and propellant in the Refueling Module. Excess propellant that is usually in the propulsion system tanks in the Instrumentation/Propulsion Module can also be used by the ISS.
