N1 - Funding Information:
LOFT was a series of transient experiments conducted at the LOFT facility at the INL. The facility was located at the INL site to the west of Idaho Falls and was sponsored by the U.S. NRC as part of their Water Reactor Safety Research Program. The LOFT reactor was a 1/2 scaled PWR with a maximum rating of 50 MW. The active core length was 1.68 m and was made up of 1300 fuel rods configured as 5 15x15 square assemblies and 4 triangular assemblies. A cross section of the core can be seen in Figure 3.

N2 - The postulated pressurized water reactor (PWR) accident known as a large break loss of coolant accident (LBLOCA) is still of great concern to the current nuclear reactor fleet. Research, through experiments and modeling and simulation, is active in the field of LOCAs and new modeling tools are under continuous development. The Bison fuel performance code, developed at the Idaho National Laboratory (INL), is one such tool that has been very active in the development of models and the simulation of accidents. With recent model developments, Bison has been used to simulate LOCA cladding burst experiments and full integral LOCA experiments with favorable results. Bison is a thermomechanical code that must be fed boundary conditions (BC) for phenomena occurring outside of the fuel rod. These BCs include moderator or outer cladding temperature, coolant pressure, and rod linear power or neutron flux. These BCs can be supplied from a function or, preferably, another coupled code. Bison is built on the Multiphysics Object Oriented Simulation Environment (MOOSE) framework which allows for ease of code coupling. A framework is currently in place that allows codes external to MOOSE to communicate with MOOSE applications as if they were a MOOSE application. Through a recent MOOSE/Bison development, with collaboration from the Nuclear Regulatory Commission (NRC), Bison has been coupled with the NRC system code TRAC/RELAP Advanced Computational Engine (TRACE). Simulation results of the initial validation Loss Of Flow Test (LOFT) L2-5 case from this research will be presented.
