A nuclear reactor using water as the moderator and coolant, in which the system is maintained at a high pressure to prevent boiling. The water is circulated through a heat exchanger to generate steam in a secondary circuit. 1, record 1, English, - pressurized%20water%20reactor
Record number: 1, Textual support number: 1 CONT
By far the most common civilian power reactor is the pressurized water reactor (PWR). ... The water passes downward through an annulus between the reactor core and the pressure vessel and then flows up over the fuel elements. It then passes through a series of pipes, which pass to the steam generator. The light coolant also acts as the moderator for this reactor. 3, record 1, English, - pressurized%20water%20reactor

Dans les réacteurs à eau sous pression, l'eau qui circule dans le coeur est maintenue à une pression supérieure à 150 bars et elle sort du réacteur à une température supérieure à 300 °C. Elle est envoyée dans des générateurs de vapeur où elle échange sa chaleur avec l'eau d'un second circuit, qu'elle vaporise. 4, record 1, French, - r%C3%A9acteur%20%C3%A0%20eau%20sous%20pression
