Whole Core Sub-Channel Analysis Verification with the EBR-II SHRT-17 Test

As part of an International Nuclear Energy Research Initiative, Argonne National Laboratory and the Korea Atomic Energy Research Institute have cooperated in developing a detailed whole core coolant sub-channel model. This model has been implemented in LMR systems codes and coupled with the primary loop treatments in these codes. Analysis of the SHRT-17 test performed in the EBR-II reactor has been used for verification of the model. Detailed steady-state and transient coolant temperature profiles and subassembly flow rates are available for an instrumented subassembly that was in the core for this test. Calculated coolant temperatures and flow rates agree well with the measured values. (authors)
