Pressurized water nuclear reactor with inherent safety.

摘要

A pressurised-water nuclear reactor with inherent safety comprises a pressurised vessel (2) filled with borated water within which is the body (3) of the reactor. The latter includes an upper part (4) and a lower part (5) within which is the reactor core (18). The upper part (4) includes a first tubular cavity (6), a second tubular cavity coaxial with and outside the first cavity (6) and a plurality of helical tube bundles (8) extending between respective pairs of connectors for the inlet (9) and outlet (10) of water circulating in the tube bundles (8).
