INVESTIGATION OF NEUTRONIC AND THERMAL-HYDRAULIC PERFORMANCE FOR HTR-10 UNDER NORMAL OPERATING CONDITIONS
Öz
The VSOP’94 code, obtained from OECD/NEA Data Bank, has been used for the neutronic and thermal-hydraulic prediction calculations for the initial core ioading of the HTR-10 reactor. In the neutronic aspect of this study, double heterogeneity for the fuel element, buckling feedback in the spectrum calculation, and mixture of graphite and fuel balls are taken into account. The results, compared to a relevant study based on the first criticality experiment of HTR-10, indicate that relative errors for the multiplication factor are less than 1.34%, being in a reasonable range.
In the thermal-hydraulic analysis, the power distribution obtained from the neutronic calculations is used where temperature and flow distributions are calculated for the reactor core. During the calculations, conservative hydraulics and physics parameters, such as minimum mass flow rates in the core, no radiation heat transfer in the axial direction, are used. The calculated maximum fuel centerline temperature is 927.4°C for normal operating conditions and observed not to exceed the safety limit.
