Nuclear Reactors 258 - Low Powered KiloPower Nuclear Reactors Being Designed For Space Missions

I have mentioned thermionic power generators that use plutonium-238 to provide power for space probes in past posts. Recently there have been some problems with obtaining sufficient Pu-238 for NASA deep space missions. Nuclear propulsion systems for large spacecraft have also been proposed for decades. With the recent expansion of private space industry, interest in nuclear propulsion has increased.

       I have often blogged about problems at nuclear power reactors. I have seldom blogged about problems with the nuclear engines that power submarines and ships. The nuclear engines are very well built and usually function reliably and safely. However, occasionally even these nuclear reactors have problems.
