Patent number: 9378854Abstract: A core catcher includes a holding surface that catches and holds corium and that introduces a surrounding coolant into the core catcher and cool the core catcher by heat exchange with the introduced coolant. The holding surface and the cooling unit are constructed by arranging blocks which each include a polyhedron having at least one pair of parallel surfaces and having an opening portion formed in a surface located in a lateral direction when a first surface that is one of the parallel surfaces is arranged as a bottom surface and are configured such that the polyhedrons communicate with each other via the opening portion when the polyhedrons are arranged adjacent in the lateral direction. The core catcher can achieve easier installation of the blocks without an increase in installation cost.Type: GrantFiled: May 14, 2012Date of Patent: June 28, 2016Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Tomohisa Kurita, Mika Tahara, Mitsuo Komuro, Noriyuki Katagiri, Masashi Tanabe

Patent number: 9025721Abstract: There is provided a holding device which can hold a molten corium for a predetermined period even when the molten corium is exposed to heat or undergoes any chemical reaction and which is applicable to practical use. There is provided a holding device provided below a nuclear reactor pressure vessel for holding a molten corium, wherein the holding device includes a base material in contact with a cooling medium, and a multilayer stack structure on the base material. The multilayer stack structure has a first layer having heat-resistant property, a second layer formed on the first layer and having heat-resistant property with lower heat conductivity than that of the first layer, and a third layer formed on the second layer and having corrosion-resistant property and impact-absorbing property.Type: GrantFiled: September 14, 2012Date of Patent: May 5, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Kunihiko Wada, Fumiyo Kuno, Yutaka Ishiwata, Tsuneji Kameda, Ryoichi Hamazaki, Noriyuki Katagiri

Publication number: 20130170598Abstract: According to an embodiment, a nuclear reactor containment vessel is provided with a device for holding a molten material of the reactor core and with spacers. The device is installed on the pedestal floor. A holding container which is open upward and a water supply container which is provided below the holding container are provided inside the outer peripheral surface. A water supply flow path extends to the water supply container from the gap between the inner surface of the pedestal side wall and the outer peripheral surface of the device for holding a molten material of the reactor core. The spacers are engaged with the upper end of an outer riser extend between the outside of the outer riser and the inner surface of the pedestal side wall, and prevent the eccentricity of the device.Type: ApplicationFiled: November 19, 2012Publication date: July 4, 2013Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Mitsuo KOMURO, Noriyuki Katagiri, Masashi Tanabe, Toshimi Tobimatsu, Yuka Shibasaki

Publication number: 20120328067Abstract: An embodiment of a nuclear power plant has: a reactor vessel containing a core; a reactor containment vessel containing the reactor vessel; and a radiation heat reflecting member disposed at a portion below the reactor vessel inside the reactor containment vessel. The radiation heat reflecting member may block radiation heat, which is emitted toward a side wall surface of the reactor containment vessel from the core that has been put in a molten state by an accident and flowed downward from the reactor vessel to be accumulated at a lower portion of the reactor containment vessel. The radiation heat reflecting member may block radiation heat, which is emitted toward a supporting structure supporting devices disposed inside the reactor containment vessel.Type: ApplicationFiled: May 23, 2012Publication date: December 27, 2012Inventors: Tomohisa KURITA, Mika Tahara, Mitsuo Komuro, Toshimi Tobimatsu, Ryo Suzuki, Ryoichi Hamazaki, Noriyuki Katagiri, Masashi Tanabe

Publication number: 20120300893Abstract: A core catcher includes a holding surface that catches and holds corium and that introduces a coolant with which surroundings of the core catcher are filled into the core catcher and cool a whole of the core catcher by heat exchange with the introduced coolant. The holding surface and the cooling unit are constructed by arranging blocks which each include a polyhedron having at least one pair of parallel surfaces and having opening portion formed in a surface located in a lateral direction when a first surface that is one of the parallel surfaces is arranged as a bottom surface and are configured such that the polyhedrons communicate with each other via the opening portion when the polyhedrons are arranged adjacent in the lateral direction. The core catcher, as described above, can be achieved easier installation of the blocks without an increase in installation cost.Type: ApplicationFiled: May 14, 2012Publication date: November 29, 2012Applicant: Kabushiki Kaisha ToshibaInventors: Tomohisa KURITA, Mika TAHARA, Mitsuo KOMURO, Noriyuki KATAGIRI, Masashi TANABE
