Power reactor inherently safe module

S-PRISM Super Power Reactor Inherently Safe Module... 

Passive safety systems similar to gas-cooled and liquid-metal-cooled reactors engineered in the 1980s and 1990s, especially the Super Power Reactor Inherently Safe Module (S-PRISM) design developed by General Electric (GE). ... 

A module has a power rating of 170 MW(th) at 950°C helium outlet temperature for process heat applications, while for electricity production or coproduction of electricity and process steam or district heating a rating of 200 MW(th) at an exit temperature of 700 °C is achieved. For reasons of economics and demand, plant sizes of 8 units appear to be an upper limit. Additionally the modular HTR as a small and inherent safe reactor system fullfil the criterion for the design of an autarc barge-mounted energy station in an optimum way.
