COMPOSITE PRESSURE SUPRESSION CONTAINMENT STRUCTURE FOR NUCLEAR POWER REACTORS

摘要

A nuclear power reactor pressure suppression containment system wherein the primary containment includes a biological shielding, vapor barrier and strength member, all of which are constructed and function as a composite structure. A conically shaped concrete pressure vessel internally lined with a gas-impervious membrane comprises the primary containment. A support structure centrally positioned within the primary containment carries the reactor vessel and internal floor independently of the primary containment vessel, the internal floor separating the drywell from the pressure suppression chamber. A secondary containment comprising a cylindrical concrete vessel houses the primary containment vessel and is also supported independently thereof on a common foundation.
