Study on Sensitivity of Control Rod Cell Model in Reflector Region of High-Temperature Engineering Test Reactor

Source: Journal of Nuclear Engineering and Radiation Science:;2017:;volume( 003 ):;issue: 001:;page 11005

Author(s): Honda, Yuki; Fujimoto, Nozomu; Sawahata, Hiroaki; Takada, Shoji; Sawa, Kazuhiro

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: The high-temperature engineering test reactor (HTTR) is a block-type high-temperature gas-cooled reactor (HTGR). There are 32 control rods (16 pairs) in the HTTR. Six of the pairs of control rods are located in a core ...

Burn-Up Dependency of Control Rod Position at Zero-Power Criticality in the High-Temperature Engineering Test Reactor

Source: Journal of Nuclear Engineering and Radiation Science:;2017:;volume( 003 ):;issue: 001:;page 11013

Author(s): Honda, Yuki; Fujimoto, Nozomu; Sawahata, Hiroaki; Takada, Shoji; Sawa, Kazuhiro

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: The high-temperature engineering test reactor (HTTR) is a block-type high-temperature gas-cooled reactor (HTGR), which was constructed in Japan. The operating data of HTTR with burn-up to about 370 EFPD (effective full-power ...

Investigation of Countermeasure Against Local Temperature Rise in Vessel Cooling System in Loss of Core Cooling Test Without Nuclear Heating

Source: Journal of Nuclear Engineering and Radiation Science:;2016:;volume( 002 ):;issue: 004:;page 44502
