Volume 2, Issue 4 , December 2021, , Pages 19-27

  Canadian GEN IV Super Critical Water Reactor (Canadian-SCWR) is a combination version of conventional CANDU reactor with the using super critical water as coolant. Thermal-hydraulic analysis of a nuclear reactor is done to ensure that reactor will work in its safety margins. In this study, thermal hydraulic ...  Read More

Second order average current nodal expansion method for time-dependent neutron diffusion simulation

Kambiz Valavi; Ali Pazirandeh; Gholamreza Jahanfarnia

Volume 2, Issue 3 , September 2021, , Pages 9-15

  In the present work, a time-dependent neutron diffusion simulator is developed utilizing the second order of average current nodal expansion method. Generally, nodal methods can accurately simulate the reactor core with coarse meshes as long as the sizes of a fuel assembly. In this case, an adopted iterative ...  Read More

Modeling the partial loss of coolant flow accident in the Super-critical water reactor

Mohammad Hossein Bahrevar; Gholamreza Jahanfarnia; Ali Pazirandeh; Mohsen Shayesteh

Volume 2, Issue 3 , September 2021, , Pages 31-39

  In this study, thermal-hydraulic analysis of partial loss of coolant flow accident in supercritical pressure light water reactor (SCWR) with a new geometric design has been investigated. In the new design, the coolant and moderator circuits are separated. This analysis was performed using the development ...  Read More
