Summary
| Description |
English: Bimodal Nuclear Thermal Rockets conduct nuclear fission reactions similar to those safely employed at nuclear power plants including submarines. The energy is used to heat the liquid hydrogen propellant. Advocates of nuclear powered spacecraft point out that at the time of launch, there is almost no radiation released from the nuclear reactors. The nuclear-powered rockets are not used to lift off the Earth. Nuclear thermal rockets can provide great performance advantages compared to chemical propulsion systems. Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation.
Français : Les fusées thermiques nucléaires bimodales produisent des réactions de fission nucléaire similaires à celles utilisées en toute sécurité dans les centrales nucléaires, y compris les sous-marins. L'énergie est utilisée pour chauffer le propulseur d'hydrogène liquide. Les partisans des engins spatiaux à propulsion nucléaire soulignent qu'au moment du lancement, il n'y a presque pas de rayonnement émis par les réacteurs nucléaires. Les fusées à propulsion nucléaire ne sont pas utilisées pour décoller de la Terre. Les fusées thermiques nucléaires peuvent offrir de grands avantages en termes de performances par rapport aux systèmes de propulsion chimique. Des sources d'énergie nucléaire pourraient également être utilisées pour fournir à l'engin spatial de l'énergie électrique pour les opérations et l'instrumentation scientifique. |
