Abstract

We have developed a calculation code system HIDEC-ALLIS for an assembly design of BWR. HIDEC performs the assembly calculation. ALLIS supplies the assembly constants library (HIDEC-ALLIS library) for the core calculation. The comparison between the results of HIDEC-ALLIS and CASMO code was carried out. The difference of k-infinity was small at BOL (0GWd/t). At MOL and EOL (50GWd/t), the difference of the k-infinity between HIDEC and CASMO code slightly increased with the burn-up exposure. The comparison of the assembly constants such as the diffusion coefficient and the removal cross-section shows that HIDEC-ALLIS and CASMO code agreed within several percent. A core calculation was performed by using SIMULATE code. The k-effective agreed well between HIDEC-ALLIS and CASMO code. From those verification results, it is considered that HIDEC-ALLIS is valid and useful for the BWR assembly calculation, considering the difference of the nuclear data library, JENDL3.3 for HIDEC-ALLLIS and the original library of CASMO. It is remarked that more comparison are required for verifying HIDEC-ALLIS.
