Abstract: The SRAC system is a reactor physics analysis program system developed by JAERI. This system includes cell calculation program, core calculation program and burnup calculation program. By using database of JENDL or ENDF/B it can deal with more than 300 nuclides. In this paper the primary application of SRAC system on China Advanced Research Reactor (CARR) was researched, and the critical calculation and burnup calculation of CARR were carried out. The comparison of the calculated results and the program system of WIMS-CITATION indicates that SRAC system is one of the good choices of the online analysis tool of CARR. The research can be a good technical base of the practical application in future.
