Radial Core Expansion Reactivity Feedback: Current Understanding and the SASSYS/SAS4A Model
- Argonne National Laboratory (ANL), Argonne, IL (United States)
The radial core expansion reactivity feedback model in SASSYS and SAS4A is reviewed, including background information, the fundamental phenomena, and a detailed discussion of the model and its options. All of the possible core loading configurations treated in the model are covered. A brief explanation of the algorithm is also included. The application of the model to the FFTF reactor is discussed in detail. The validation of the model with FFTF experimental results is presented for both steady-state and transient conditions. The estimate of the radial core expansion reactivity feedback for the proposed metallic fuel core in FFTF is provided, along with the underlying assumptions and cautions.
