Patent number: 5112571Abstract: In a fuel assembly having fuel rods inserted into regularly arranged cells of a fuel spacer which keeps the fuel rods correctly spaced from one another and has spacer elements disposed in a plurality of stages in the longitudinal direction of the fuel rods, the fuel spacer comprises vanes formed on the cells in such a manner that each vane is bent from a cut formed in a part of the side wall of the cell. The vanes obliquely project into the corresponding spaces between adjacent fuel rods and allow a coolant flowing through the spaces and forming two-phase flows to generate swirling flows toward the fuel rods. The fuel spacer may alternatively comprise either thin-walled cylinders having built-in vanes or spiral vanes, which are fixed to the spacer that has not been subjected to any direct machining. Also disclosed is a fuel assembly provided with any of the above-described fuel spacers.Type: GrantFiled: April 17, 1990Date of Patent: May 12, 1992Assignee: Hitachi, Ltd.Inventors: Akihito Orii, Osamu Yokomizo, Yasuhiro Masuhara, Koji Nishida, Shigeto Murata, Shin-ichi Kashiwai, Kotaro Inoue, Yuichiro Yoshimoto

Patent number: 4926450Abstract: A fuel assembly including a plurality of fuel rods and water rods. The fuel rods are arranged with a predetermined pitch and two water rods are disposed adjacent to each other in a diagonal direction of the fuel assembly. More particularly, the fuel rods are arranged in a lattice of nine rows by nine columns and the two water rods are disposed inside a region corresponding to a space sufficient for disposing seven fuel rods at the center of the fuel assembly. Each of the water rods has an outer diameter greater than the pitch of the fuel rods.Type: GrantFiled: March 21, 1988Date of Patent: May 15, 1990Assignee: Hitachi, Ltd.Inventors: Yasuhiro Masuhara, Soamu Yokomizo, Kotaro Inoue, Sadao Uchikawa, Motoo Aoyama, Junichi Yamashita, Yuichiro Yoshimoto, Tetsuo Yasuda, Hiromasa Hirakawa

Patent number: 4877574Abstract: A natural circulation reactor includes a reactor pressure vessel, a cylindrical shroud disposed within the reactor pressure vessel to surround a reactor core and to extend to a position above the reactor core, and a coolant descending passage defined between the reactor pressure vessel and the shroud for allowing the coolant discharged from the top of the reactor core to be again supplied to the bottom of the reactor core. In such a natural circulation reactor, a liquid level of coolant in the coolant descending passage is adjusted on the basis of a reactor power request signal at a position below a liquid level of coolant in the shroud, and thus reactor power is controlled so that it may reach a predetermined reactor power by adjusting the liquid level of coolant in the coolant descending passage.Type: GrantFiled: March 2, 1988Date of Patent: October 31, 1989Assignees: Hitachi, Ltd., Hitachi Engineering Co., Ltd.Inventors: Hiroaki Suzuki, Yoshiyuki Kataoka, Michio Murase, Kotaro Inoue, Isao Sumida, Shozo Yamanari, Masaki Matsumoto, Satoshi Miura, Koji Hashimoto

Patent number: 4732729Abstract: In the fast breeder reactor according to this invention, a medium-pressure plenum and a high-pressure plenum are disposed, in the mentioned order from above in a reactor core. Sodium is filled in the medium- and high-pressure plenums. The pressure in the medium-pressure plenum is lower than that in the high-pressure plenum. The lower ends of the entrance nozzles of a multiplicity of fuel assemblies loaded in the reactor core are supported by a supporting plate which forms a boundary between the medium- and high-pressure plenums. The entrance nozzles of control rod guide pipes disposed among the multiplicity of fuel assemblies are also supported by said supporting plate. The sodium in the medium-pressure plenum is supplied into each control rod guide pipe through a first opening provided in the lateral surface of the entrance nozzle of each control rod guide pipe.Type: GrantFiled: February 21, 1985Date of Patent: March 22, 1988Assignee: Hitachi, Ltd.Inventors: Ken Amano, Kotaro Inoue
