Latest Patents

Hasegawa's latest patents include innovative designs for fast reactors. The first patent describes a fast reactor that features a reactor vessel accommodating a core and a primary coolant. This design includes a core support that holds the core from below and a bulkhead that surrounds the core from the lateral side. An intermediate heat exchanger is positioned between the inner surface of the reactor vessel and the bulkhead, which cools the primary coolant. Additionally, an electromagnetic pump is integrated to pressurize the cooled primary coolant, with a neutron shield supported by an upper supporting plate positioned below the pump.

The second patent presents a fast reactor equipped with a reactivity control reflector. This reactor includes a vessel containing coolant and a core that is submerged in the coolant. The reflector is designed to be movable in a vertical direction, allowing for precise control of the reactor core's reactivity. It features a lower neutron reflecting portion with a higher reflection capability than the coolant, and an upper cavity portion composed of multiple cylindrical hermetically-sealed vessels.
