RIA Experimentation Benchmark

Significant developments have been applied to the Bison code to make it capable for Reactivity- Initiated Accident (RIA) simulations. This report documents efforts to demonstrate the current Bison capabilities for an RIA simulation with a comparison to experimental and benchmark data. A number of CABRI REP and CIP cases have been modeled and compared to experimental and other code prediction results. This work shows that Bison is capable of predicting thermal, mechanical, and fission gas release data in agreement with the experimental results and other fuel performance code predictions.

Modeling Fission Gas Behaviour with the BISON Fuel Performance Code

The behavior of fission gases (Xe, Kr) is of critical importance to nuclear fuel performance, because it determines both the amount of fuel swelling and the quantity of fission gas released to the fuel rod plenum. It follows that accurate models of fission gas behavior need to be developed for the calculation of fission gas swelling and release in fuel performance codes, such as the BISON code developed at Idaho National Laboratory (INL). To this end, the fission gas behavior model included in BISON is being continually extended and improved. In the present contribution, we give an account of the most recent developments and results on modeling fission gas behavior in uranium dioxide fuel with BISON.
