Difficulties of the Nuclear Powered Prometheus Project

Posted by michael on from the nukes-in-space dept.

brandido writes "Space.com is reporting on some of the technological difficulties facing the nuclear powered Prometheus Project. In particular, it is focusing on the fact that the Prometheus project promises to represent a paradigm shift in the capabilities of interplanetary probes. Such a large shift in capabilities entails the development of new technologies and designs, a process that is often full of mishaps and setbacks."

    Firstly, unused nuclear fuel is not very radioactive relatively speaking and is not very toxic.
    Secondly, the fuel can (and is) built into very strong and resilliant "cans" and can be further protected to the point that even a fall from a great height such as earth-orbit will not result in any radioactive release.
    Thirdly, any engineer woth their salt will design the darned thing such that it will not start its nuclear reactor (when the nasty fission products start to be produced) until the craft is either a significant distance away from earth already, or has achieved escape velocity and can not fall back to earth.
    I am a qualified nuclear engineer with several years reactor physics experience at a nuclear power station.
