Patent number: 8483349Abstract: A spacer grid for dual-cooling nuclear fuel rods arranged at a narrow interval. The spacer grid solves the problem in which, since the dual-cooling nuclear fuel rods are used to improve the cooling performance and stability of nuclear fuel and obtain high burnup and output, the outer diameter of each dual-cooling nuclear fuel rod is increased, and thus the gap between each dual-cooling nuclear fuel rod and the grid strap is decreased. The spacer grid includes first grid straps and second grid straps, which are crossed and arranged in transverse and longitudinal directions at regular intervals and have the shape of a flat strip, and support structures, which are fitted into the first and second grid straps around intersections of the first and second grid straps so as to support the dual-cooling nuclear fuel rods.Type: GrantFiled: July 29, 2008Date of Patent: July 9, 2013Assignee: Korea Atomic Energy Research InstituteInventors: Jae-Yong Kim, Hyung-Kyu Kim, Kyung-Ho Yoon, Young-Ho Lee, Kang-Hee Lee

Patent number: 8243872Abstract: A spacer grid can be applied to close-spaced nuclear fuel rods. The spacer grid is directed to solve the problem in which, as the outer diameter of each nuclear fuel rod increases due to the use of dual-cooled nuclear fuel rods for improving cooling performance and obtaining high combustion and high output power, the gap between the neighboring nuclear fuel rods is narrowed to thus make it impossible to use an existing spacer grid. The spacer grid is a combination of unit grid straps, each of which has supports for supporting each of the nuclear fuel rods set in a narrow array and has a sheet shape, which are combined with each other. The supports are located at positions shifted from the longitudinal central line of each unit grid strap toward sub-channels.Type: GrantFiled: June 26, 2008Date of Patent: August 14, 2012Assignee: Korea Atomic Energy Research InstituteInventors: Kang-Hee Lee, Hyung-Kyu Kim, Kyung-Ho Yoon, Young-Ho Lee, Jae-Yong Kim, Tae-Hyun Chun, Wang-Kee In, Dong-Seok Oh, Chang-Hwan Shin
