Award to Upgrade the INL ATR Training Simulator for Use of LEU
WSC was awarded a contract by Idaho National Laboratory (INL) to
upgrade the Advanced Test Reactor (ATR) Training Simulator to support the planned transition from using
High Enriched Uranium (HEU) fuel to Low Enriched Uranium (LEU) fuel.
LEU insertion is planned for 2023 and to support the ATR Simulator upgrade to
use LEU in the ATR core, WSC will:
- Integrate Core Model Updates for the
LEU provided by Studsvik
- Upgrade the thermal-hydraulic
models by increasing the number of flow paths and nodes to more accurately
model the fuel temperature distribution in the assembly and provide correct
feedback to neutronics model at various elevations.
- Provide two GlassTop
Simulators to support testing of the ATR with LEU inserted in the core. The
GlassTops provide a standalone hardware platform that will provide flexibility
for use of the simulator at any location INL desires the GlassTops to be used.
