EVACUATED CONTAINMENT VESSEL FOR A NUCLEAR REACTOR

摘要

A system includes a containment vessel configured to prohibit a release of a coolant, and a reactor vessel mounted inside the containment vessel. An outer surface of the reactor vessel is exposed to below atmospheric pressure, wherein substantially all gases are evacuated from within the containment vessel.

主权项

1. A power module assembly comprising:
a containment vessel; a reactor vessel housed in the containment vessel, wherein the reactor vessel is configured to release coolant into a containment region located between the reactor vessel and the containment vessel, and wherein the containment vessel is configured to prohibit the released coolant from escaping out of the containment vessel; and a thermal insulation of the reactor vessel including the containment region located between the reactor vessel and the containment vessel, wherein the containment region comprises a partial vacuum that substantially surrounds the reactor vessel and is maintained at a below atmospheric pressure of less than 300 mmHG absolute.
