Development of CANDU-PHWR Neutronics Code SCAN

Abstract

The SCAN code designed as a CANDU-PHWR physics research and development tool in Korea is introduced. In an effort to validate the SCAN code, Wolsong unit 3 phase-B reactor physics measurements are analyzed by 1.5 group and 2 group SCAN model. The results are compared with the corresponding RFSP model calculations. It is shown that the SCAN code can predict the CANDU-PHWR core neutronics parameters of major importance as accurately as the RFSP with much less CPU time and better convergence characteristics.
