Title: Heat dissipating nuclear reactor with metal liner

Abstract

A nuclear reactor containment including a reactor vessel disposed within a cavity with capability for complete inherent decay heat removal in the earth and surrounded by a cast steel containment member which surrounds the vessel is described in this disclosure. The member has a thick basemat in contact with metal pilings. The basemat rests on a bed of porous particulate material, into which water is fed to produce steam which is vented to the atmosphere. There is a gap between the reactor vessel and the steel containment member. The containment member holds any sodium or core debris escaping from the reactor vessel if the core melts and breaches the vessel.

  • A nuclear reactor containment is described comprising: reactor vessel means disposed in a metal cavity located partially or completely below the surface of the earth in a cavity, a cast steel containment member partially surrounding the reactor vessel means and having an inner surface conforming in shape to an exterior surface of the reactor vessel means. The cast steel member has a solid thick base plate which extends at least across a bottom area of the reactor vessel means, means located below the base plate but adjacent to it for feeding water to a porous media disposed in the hotmore » zone immediately underneath the base plate. The water is converted to steam when the temperature of the hot zone exceeds the boiling point of water, means of venting the steam so formed to the atmosphere, and means in contact with the base plate for supporting at least the base plate and for conducting heat away from the base plate.« less
  • Disclosed is a nuclear reactor containment adapted to retain and cool core debris in the unlikely event of a core meltdown and subsequent breach in the reactor vessel. The reactor vessel is seated in a cavity which has a thick metal sidewall that is integral with a thick metal basemat at the bottom of the cavity. The basemat extends beyond the perimeter of the cavity sidewall. Underneath the basemat is a porous bed with water pipes and steam pipes running into it. Water is introduced into the bed and converted into steam which is vented to the atmosphere. A pluralitymore » of metal pilings in the form of H-beams extend from the metal base plate downwardly and outwardly into the earth.« less
  • This patent describes a nuclear reactor containment comprising: reactor vessel disposed in a metal cavity located partially or completely below the surface of the earth in a cavity, a guard vessel, the reactor vessel being positioned within the guard vessel, a thick metal basemat beneath the reactor vessel and guard vessel and at the bottom of the cavity, means located below the basemat but adjacent to it for feeding water to a porous media situated in a zone immediately underneath the basemat, the water being converted to steam when the temperature of the zone exceeds the boiling point of water,more » means for venting the steam so formed to the atmosphere, and means in contact with the basemat for supporting same and for conducting heat therefrom.« less
