MP98' very high temperature reactor design :

In this design MP98' components are suitable for high temperature. Here MP98’ neutron absorber tanks are located at the bottom of each fuel assembly, but the principle is the same than for Light Water Reactors.



MP98' gas fast reactor design :

in MP98'GFR design, a metallic circuit is in interface between primary gas coolant and secondary gas coolant. The heat exchange is done with a very good efficiency and gases from primary and secondary circuits are well separated.

MP98' metallic fast reactor design :

MP98' Metallic cooled Fast Reactor could be used with any kind of metallic coolant and any kind of gas coolant. It gives the opportunity to use sodium directly with inert coolant gas like nitrogen. This design decreases the risks in that kind of reactors.
Design becomes more simple.

Possible applications of MP98’ technology:

MP98' technology is suitable for many reactor designs. Studies needed are the same for all reactors. First theoretical results shows some big advantages.
Reactivity control system for VHTR is on the same design than for LWR
Valves first prototype are working as said.
A mock up of Heat exchanger is going to be build in march 2004.
Technology of HTR is complex, because of weakness of materials at high temperature. In some particular cases, it's more difficult to adapt existing and proved technology than finding new solutions.
When it's possible, it's easier to bypass technical problems and suppress the origin of weakness. That's what guides our search in control rods, valves or heat exchanger adapted on High Temperature Reactors.
