Beyond the nuclear rocket designs, the United States also launched a small nuclear reactor, SNAP10a, into space that generated electricity.

The idea behind the reactor was to use the heat generated by fission to heat hydrogen, which would expand, generating the force to push the rocket.

这一试验的原理是运用核裂变产生的热量给氢气加温，导致其膨胀，并产生推动火箭的力量。

Then, once the vehicle had ascended to high-Earth orbit, above about 800 kilometers, the nuclear reactor module would detach from the chemical rocket and start up.

这样，当普通燃料火箭到达地球轨道约800公里高度时，核反应堆舱会脱离化学燃料火箭，并开始工作。
