Very simplified boiling water reactors for commercial electricity generation

A nuclear reactor power plant for commercially generating electricity, the plant comprising:

• a maximum 1000 megawatt-thermal rated boiling water nuclear reactor having a height that exceeds its width by a factor of at least 3.9;
• a containment completely and impermeably surrounding the nuclear reactor, wherein there is no open coolant source or active pump inside the containment, and wherein the containment is completely underground;
• at least one primary coolant loop connecting to the nuclear reactor through the containment;
• at least one emergency coolant source outside the containment and connecting to the nuclear reactor through the containment, wherein the primary coolant loop and the emergency coolant source are integral with the nuclear reactor inside containment;
• a plurality of isolation valves connecting the primary coolant loop and the emergency coolant source to the nuclear reactor through the containment, wherein each of the isolation valves includes a primary and a secondary actuator, and wherein each of the isolation valves is integral with the nuclear reactor;
• a plurality of penetration seals, wherein each one of the penetration seals lines and seals the containment at each one of the isolation valves;
• and
• a silo surrounding the containment and the emergency coolant source, wherein the silo is a seismic structure configured to reduce seismic shocks to the containment, the emergency coolant source, and the nuclear reactor.

A simplified nuclear reactor facility for commercially generating electricity, the facility comprising:

• a nuclear reactor;
• a containment completely and impermeably surrounding the nuclear reactor, wherein there is no open coolant source or active coolant pump inside the containment;
• at least one primary coolant loop connecting to two of a plurality of isolation valves of the nuclear reactor through the containment;
• and
• an isolation condenser system outside the containment with a pool configured to condense a coolant of the nuclear reactor and transfer heat from the nuclear reactor to ambient environment connecting to two of the plurality of isolation valves of the nuclear reactor through the containment, wherein each of the plurality of isolation valves,
• includes a primary and a secondary actuator,
• is integral with the nuclear reactor, and
• is configured to be passively opened and passively sealed.
