In nuclear power plant the fuel contain fissile component (U-235 and/or Pu- 239) that must be treated in order to be used.
Nuclear fuel undergoes a strict process to obtain the right material.
ALD France intervenes at different stage of this process and has a long experience in the heat treatment of the fuel pellet.
There are three main stages in the fabrication of the nuclear fuel structures used in LWRs and PHWRs:
