There are very few icebreakers fitted with steam turbine systems other than nuclear powered vessels. Nuclear powered icebreakers use their steam turbines to generate electrical power to operate electric propulsion motors, in exactly the same way conventional diesel-electric icebreakers operate – only the prime mover is different. 2, record 1, English, - nuclear%2Dpowered%20icebreaker

In a nuclear electric propulsion system, heat from a nuclear reactor is converted to electrical energy either by direct thermoelectric or thermionic conversion. NEP provides higher power, thrust, and specific impulse than a SEP [solar electric propulsion] system, although the thrust still pales to insignificance compared to our chemical rockets. For a comparison specific impulse of chemical rockets is about 400secs, Deep Space 1 uses SEP and produces around 3300secs, NEP on the other hand could produce specific impulse as high as 13, 000secs. 1, record 4, English, - nuclear%20electric%20propulsion

In nuclear thermal propulsion, a propellant gas is heated as it flows through the core of a nuclear reactor and is then expanded and expelled through a rocket nozzle. The reactor core can be a solid(e. g., uranium carbide particles in a graphite matrix or uranium nitride in a ceramic matrix), liquid, or a gas/plasma. The last two approaches can produce much higher propellant temperatures, resulting in higher specific impulse and greater rocket efficiency. 2, record 8, English, - nuclear%2Dthermal%20propulsion

Le VASIMR (Variable Specific Impulse Magnetoplasma Rocket, ou «fusée à magnétoplasma à impulsions spécifiques variables») comble la lacune entre les systèmes à forte et à faible poussée. De l'hydrogène est d'abord ionisé par des ondes radio, puis guidé vers une chambre centrale où l'on fait régner un champ magnétique. Là, les particules longent les lignes de champ magnétique en tournant autour d'elles à une fréquence qui ne dépend que de leur charge électrique et de leur masse (la fréquence de Larmor). En bombardant les particules avec des ondes radio à la même fréquence, on les chauffe jusqu'à des températures de dix millions de degrés. Une tuyère magnétique transforme enfin le déplacement en spirale en déplacement axial, ce qui engendre la poussée. En réglant le chauffage et le convertisseur magnétique de sortie, le pilote commande la vitesse d'éjection. Le mécanisme est analogue à celui du levier de vitesse d'une voiture. En fermant l'étranglement de sortie, la fusée passe «en cinquième» : on réduit le nombre de particules excitées (et donc la poussée), mais on augmente leur température (et donc la vitesse d'éjection). 4, record 10, French, - fus%C3%A9e%20%C3%A0%20magn%C3%A9toplasma%20%C3%A0%20impulsions%20sp%C3%A9cifiques%20variables
