RISA Constraint Method for Supersaturation in a Variational Data Assimilation System
Publisher: American Meteorological Society
Study on Sensitivity of Control Rod Cell Model in Reflector Region of High-Temperature Engineering Test Reactor
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
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 ...
Uncertainty Analysis for Source Term Evaluation of High Temperature Gas-Cooled Reactor Under Accident Conditions—Identification of Influencing Factors in Loss-of-Forced Circulation Accidents
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the key elements in probabilistic risk assessment is the identification and characterization of uncertainties. This paper suggests a procedure to identify influencing factors for uncertainty in source term evaluation, ...
Promising Neutron Irradiation Applications at the High Temperature Engineering Test Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
