Follow-up Analysis of HFETR Burn-up By CELL/CPL493 Code

This paper briefly introduced the methodology of the CELL/CPL493 code system, and follow-up analysis of the multi-cycles burn-up for High Flux Engineering Test Reactor （HFETR） had been perform by using of the CELL/CPL493 code system. At the same time, the comparisons of the critical control rod positions at cold case and operation condition between the calculation values and measured ones had been presented. The numerical results showed that the maximum deviation in keff was less than 1%, which was very satisfactory.
