A UNIST research group, COmputational Reactor physics and Experiment (CORE), has developed a new two-step LWR core analysis code system, STREAM/RAST-K. STREAM is a lattice physics code using Method of Characteristics (MOC) to solve a Fuel Assembly problem and generate homogenized cross sections and ADFs. In the STREAM, UNIST CORE group has developed/implemented a new very accurate resonance treatment method, PSM, which removed the biases of the results on uranium enrichment and/or burnup. RAST-K uses those equivalence data to simulate three-dimensional LWR core steady states, depletion and transients.
In RAST-K, many advanced methods / engineering features have been developed/implemented: micro depletion, internal TH solver, TCD model, multi-cycle simulation, various search options, B-10 depletion, pin power reconstruction, DNBR calculation, ASI adaptation, and CRUD modelling. In the seminar, RAST-K methodology and some verification/validation results will be presented.
