Abstract
The sensitivity of DNBR values to approaches of subchannel control volume selection has been investigated for the TS01 and TS03 out of HIPER17 CHF tests. In rod bundle analysis, most of the subchannel analyses used the coolant-centered subchannel nodal layout. But, it has been known that the rod-centered subchannel analysis showed good results for high quality critical heat flux. In this study, it was demonstrated that the rod-centered subchannel analysis showed more effective and conservative results than the coolant-centered subchannel analysis with the DNBR value, the quality, and the mass velocity. Also, it was verified that when the both results yielded from each subchannel analysis were compared, the subchannel locations at which DNBR occurred were similar.
