Availability Notice


An integral assessment has been performed for the U.S. Nuclear Regulatory Commission by Pacific Northwest National Laboratory to quantify the predictive capabilities of FRAPTRAN, a transient fuel behavior code designed to analyze fuel behavior during a range of power and coolant transients with fuel burnup up to 62 gigawatt-days per metric ton of uranium. The FRAPTRAN code calculations are shown to compare satisfactorily to a set of experimental data from reactivity-initiated accident and loss-of-coolant-accident operating conditions.

This document describes the assessment of FRAPTRAN 1.4, which is the latest version of FRAPTRAN, released May 4, 2009.
