In one embodiment, a thermal energy storage power plant includes a thermal accumulator to accumulate thermal energy and heat a thermal medium with the thermal energy, and a steam generator to generate steam using the thermal medium. The plant further includes a first path to convey the thermal medium from the accumulator to the generator, and a second path to convey the thermal medium from the generator to the accumulator. The plant further includes an auxiliary module provided on the first path, and a bypass path to convey the thermal medium flowing through the second path to the auxiliary module by bypassing the accumulator, wherein the auxiliary module is supplied with a first thermal medium from the accumulator via the first path, supplied with a second thermal medium from the second path via the bypass path, and supplies a third thermal medium to the generator via the first path.

According to one embodiment, a heat transport apparatus includes an evaporator, a cooling unit, a channel structure, and a heating mechanism. The evaporator vaporizes a refrigerant by heat generated by a heat-generating element. The cooling unit is provided above the evaporator and cools and condenses the refrigerant vaporized in the evaporator. The channel structure constitutes a channel through which the refrigerant circulates between the evaporator and the cooling unit. The heating mechanism heats the cooling unit and suppresses solidification of the refrigerant at the cooling unit.

Heat transport apparatus

The pressurized water reactor according an embodiment comprises: a cylindrical reactor pressure vessel () to which inlet nozzles are connected; fuel assemblies which are contained within the reactor pressure vessel (); a cylindrical reactor core barrel () which surrounds the fuel assemblies and forms an annular downcomer () between the reactor core barrel () and the inner surface of the reactor pressure vessel (); and radial supports. The radial supports are supports which are arranged below the downcomer () at intervals in the circumferential direction, each has vertical flow path formed therein, and position the reactor core barrel () and the reactor pressure vessel (). The radial supports each has, for example, a flow path-equipped radial keys () and a key groove member ().

Pressurized water reactor

There is provided a microbubble generating method including: supplying a gas to a rotatorwhile rotating the rotatorin a liquid; injecting the gas into the liquid from bubble injection holes formed in the surface of the rotator; and applying a shear force, produced by the relative movement between the liquid and the rotator, to gas bubbles present on and in the vicinity of the surface of the rotatorto generate microbubbles. The microbubble generating method can easily generate a large amount of microbubbles without forcibly creating a swirling flow of fluid.
