MP98'
Reactivity Control System can be adapted on HTR and it presents many
advantages.

MP98'
Reactivity Control System is an adaptation from LWR technology and is
an evolution of proved technology used in existing PWR. Many materials
chosen or physical principles are well known in the nuclear field and
do not required new technology development.
|
|
MP98'
reactivity control technology is adaptable to any type of fuel. Fuel
design could be saved. And so MP98 system could be used as well on
VHTR, GFR, LFR, PBMR.
|
|
For
MP98’ VHTR design, conduits are located in the internal.
Connections and tanks could be located upper or under the fuel.
|
All
penetrations in the reactor vessel and in the vessel head are suppress.
|
Neutron
absorber vaporization temperature is upper than 2300°C.
|
Injection
tubes are located in the assembly. There is no risks of damages due to
differential dilatation.
|
|
With
MP98' technology, we could reduce the size of the reactor vessel.
Reactor containment highness could be drastically reduce.
|
This
technology is actually under development for LWR as principle is the
same for VHTR and LWR, studies are common and adaptation will be done
at low cost.

You
will find next page some possible applications of MP98 technology on
several kind a reactors.
