Fuel Model Studies. Comparison of Our Present Version of GAPCON-THERMAL-2 with Results from the EPRI Code Comparison Study. Partial Report

摘要

Runs with our present version of GAPCON-THERMAL-2 have been compared to results from the EPRI code comparison study. Usually also our version of GAPCON predicts high temperatures, 100-300 K or 10-15% higher than average code predictions and experimental results. The well-known temperaturegas release instablility is found also with GAPCON. In this case one identifies the gas release limits 1400 deg C and 1700 deg C as instablility points.
