Evaluation of a consistent point-kinetics model for the TMI-1 MSLB benchmark problem
- Argonne National Lab., IL (United States)
The SAS-DIF3DK coupled code system is currently being used for analyzing the Three Mile Island Unit 1 (TMI-1) main-steam-line-break (MSLB) benchmark problem sponsored by the Organization for Economic Cooperation and Development Nuclear Energy Agency, the US Nuclear Regulatory Commission, and the Pennsylvania State University. The code uses the DIF3D-K spatial kinetics module for calculating the detailed core power evolution during the transient. The current analysis of the benchmark problem focuses on exercise 2, in which performance of three-dimensional, coupled neutronic/thermal-hydraulic codes is being evaluated. For this exercise, thermal-hydraulic boundary conditions are prescribed. Other exercises are defined to model the whole reactor system using point kinetics (exercise 1) and multidimensional kinetics (exercise 3) for calculating the power evolution. These exercises are useful for evaluating the accuracy of the point-kinetics schemes currently used in the nuclear industry for analyzing such transient scenarios.
