A reactor core with each fuel rod surrounded by an individual cylindrical channel is disclosed. This individual channel on each fuel rod provides thermal hydraulic and heat transfer advantages to enable all fuel rods within the fuel bundle to uniformly approach their own thermal limits. The preferred fuel rod pitch is a triangular pitch between the individual fuel rods as they are discretely surrounded by their own channel. The new triangular geometry provides for more uniform (flat) power distributions within all fuel rods－and hence all groups of fuel r...
In a core for a nuclear reactor wherein said reactor includes: a reactor pressure vessel; a core central of said pressure vessel for containing fuel in sealed tubes for undergoing fission reaction; moderator coolant for circulation through said pressure vessel for extracting the heat of fission from said sealed tubes; a defined flow path for circulation of said moderator coolant through said vessel including a first upwardly passing leg in said flow path from the bottom of sad core to the top of said core in contact with said sealed tubes for undergoing ...
