pressurized water reactor

• Type de réacteur nucléaire dans lequel l'eau est maintenue sous haute pression pour empêcher son ébullition, permettant ainsi le transfert de chaleur du cœur du réacteur vers le générateur de vapeur. C'est le type de réacteur nucléaire de puissance le plus répandu dans le monde.

A type of nuclear reactor in which water is kept under high pressure to prevent it from boiling, allowing it to transfer heat from the reactor core to a steam generator. It is the most common type of nuclear power reactor worldwide.

1. Nuclear reactor typeC2formal

   A type of nuclear reactor in which the water used as a coolant and moderator is kept under high pressure to prevent it from boiling, allowing it to transfer heat efficiently to a secondary steam circuit.

   réacteur à eau pressurisée

   • Pressurized water reactors are the most common type of nuclear reactor used worldwide.
   • The primary loop of a pressurized water reactor operates at over 150 atmospheres of pressure.
   • Engineers monitor the coolant temperature in the pressurized water reactor to ensure safe operation.
