Thermal hydraulic calculations in the SAS-DIF3DK coupled reactor physics and thermal hydraulics code.

PDF Version Also Available for Download.

Description

The SAS-DIF3DK code couples a detailed 3-D neutron kinetics treatment with a detailed thermal hydraulics treatment. One goal of the work on SAS-DIF3DK is to produce a detailed code that will run a wide range of transients in real time. Achieving this goal will require efficient numerical methods and efficient coding, and it will probably require the use of multiple processors for larger problems. It has previously been reported that the thermal hydraulics treatment in the code achieves the required speed for typical PWR and BWR cases. This paper presents results from thermal hydraulic analysis of severe LOCA cases in ... continued below

Description

The SAS-DIF3DK code couples a detailed 3-D neutron kinetics treatment with a detailed thermal hydraulics treatment. One goal of the work on SAS-DIF3DK is to produce a detailed code that will run a wide range of transients in real time. Achieving this goal will require efficient numerical methods and efficient coding, and it will probably require the use of multiple processors for larger problems. It has previously been reported that the thermal hydraulics treatment in the code achieves the required speed for typical PWR and BWR cases. This paper presents results from thermal hydraulic analysis of severe LOCA cases in a Soviet design RBMK reactor, and shows that the computing speed goals are also met in these cases.
