Spider Arm Reactor

 The spider arm reactor was developed after the Fukushima incident to provide finally a completely safe way of generating nuclear energy on a medium or small scale. 

It does not rely on control rods which are prone to failure nor does it contain water which is prone to fracture into a plasma state including hydrogen which is explosive and what blew up the buildings in Fukushima Japan. 

All of the systems in the spider arm reactor are mechanical and automatically fail safe when energy is lost slowing the reaction and safely terminating fission.

Due to the rules in the USA regarding investing in nuclear designs it is impossible to secure a grant unless you are an existing nuclear reactor manufacturer like Westinghouse. So at this point the technology is waiting for a country that is willing to develop safe plentiful energy systems.
