Direct cycle : A term used to indicate that the coolant in a nuclear reactor serves also as the working fluid in the thermodynamic power cycle, and passes from the reactor to the turbine without the need for an intermediate heat exchanger. There are considerable thermodynamic and economic advantages to this arrangement. 2, record 1, English, - direct%20cycle
Record number: 1, Textual support number: 2 CONT
The turbine employs a conventional regenerative cycle with condenser deareation and condensate demineralization. The direct-cycle system is used because of its inherently simple design, contributing to reliability and availability. 1, record 1, English, - direct%20cycle

L'utilisation d'un cycle direct est la caractéristique importante qui distingue les réacteurs B.W.R. des P.W.R. Le système de production de vapeur est simplifié; par contre, il faut se prémunir contre l'entraînement de produits radioactifs susceptibles de contaminer la turbine et de gêner son entretien. 2, record 1, French, - cycle%20direct

Cycle dans lequel le mélange d'eau et de vapeur est entraîné dans des séparateurs de vapeur situés dans la partie supérieure de la cuve et, tandis que la phase liquide est réintroduite à l'entrée du cœur, la vapeur est envoyée directement à la turbine. 2, record 1, French, - cycle%20direct

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 2, English, - pressurized%20water%20reactor
Record number: 2, 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 2, 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 2, French, - r%C3%A9acteur%20%C3%A0%20eau%20sous%20pression
