The US nuclear energy industry is investigating strategies to increase the reactor operating
cycle to 24 months, which would result in rod average burnups exceeding the current limit of …

Fuel fragmentation, relocation, and dispersal are some of the largest issues remaining in the
nuclear industry before rod-average burnup can be increased beyond 62 GWd/tU. The issue …

In the first part of this work, we discussed BISON fuel performance code developments for
Zircaloy cladding behavior under loss-of-coolant accident (LOCA) conditions and validation …

The transient fission gas release (tFGR) during the temperature ramp associated with a loss-
ofcoolant accident (LOCA) in light-water reactors (LWRs) is likely a significant contribution to …

The process for developing and qualifying nuclear fuels for commercial nuclear application
requires fundamental material development, characterization, and design; out-of-pile testing …

BISON is a finite-element based, multidimensional fuel performance code developed at
Idaho National Laboratory. In this paper, we present BISON modeling developments for …

BISON is a modern finite-element based, multidimensional nuclear fuel performance code
that is under development at Idaho National Laboratory (USA). Recent advances of BISON …

Analytical criteria for the onset of fuel fragmentation and Burst Fission Gas Release in fuel
rods with ballooned claddings are formulated. On that basis, the GRSW-A model integrated …

Since 2013 CASL has been planning and working towards a PWR LOCA Challenge
Problem. Since BISON is the CASL fuel rod simulation platform, it plays a central role in that …

Modeling developments and simulations of iron-chromium-aluminum (FeCrAl) cladding
behavior under loss-of-coolant accident (LOCA) conditions have been performed using the …
