1. A modular nuclear reactor system comprising:
- a reactor pressure vessel having a lower section having a first wall and a second wall and an upper section having a first wall and a second wall;
said walls of said lower section and said upper section adapted to be connectable;
said second wall of said upper section defining a chimney having a first open end and an opposingly located second open end, said chimney disposed in said upper section and defines a first passageway;
a second passageway disposed between said chimney and said first wall of said upper section;
said upper section further including an upper plenum in communication with said first open end of said chimney and connecting said first and second passageways of said upper section;
a heat exchanger disposed in said second passageway of said upper section;
said first wall lower of said lower section opposingly located from said second wall of said lower section to form a first passageway, said first passageway in communication with said first passageway of said upper section;
said second wall of said lower section defining a second passageway, said second passageway in communication with said second passageway of said upper section;
said lower section further including a lower plenum connecting said first and second passageways of said lower section;
a reactor core located within said second passageway of said lower section, said reactor core adapted to heat a heat transfer fluid and including one or more passageways in communication with said second passageway of said lower section; and
said first and second passageways create a circulation loop wherein heated heat transfer fluid circulates up from said reactor core, through said chimney, through said upper plenum and downwardly past said heat exchanger, into said lower plenum and into said passageways of said core.

Abstract
The present invention provides a modular nuclear reactor system comprising a reactor pressure vessel having a lower section having a first wall and a second wall and an upper section having a first wall and a second wall. The reactor includes a chimney with an attached heat exchanger. First and second passageways create a circulation loop wherein heated heat transfer fluid circulates up from the reactor core, through the chimney, through an upper plenum and downwardly past the heat exchanger, into a lower plenum and back into the core.
