| Abstract: | An attempt is made to investigate the ability of the revised K-FIX code to the solution to natural convection. The new experimental data of the benchmark probl em of the IAEA coordinated research program (CRP-3) on heat transport and after heat removal for GCRs under accident conditions provided by JAERI are used to c alculate nitrogen natural convection in the pressurized vessel and air natural c onvection in the reactor cavity by using this revised code. Based on analysis, a refined mesh is used to solve the differential equations so as to get more deta iled and more accurate result. The obtained velocity profiles are consistent wit h the result of TRIO-EF code and the result of Bechtel laboratory. It can be d rawn that the revised K-FIX code can be used to solve this kind of problems. |
