Core Functions
Advanced Fuels and materials irradiation. Water-cooled, high-flux test reactor.
Unique Functions
Six in-pile pressurized water loops currently provide prototypic PWR conditions (pressure, temperature, flow, water chemistry) for fuel and material samples with the ability to tailor the neutron flux to meet desired conditions. Each loop has a full range of instrumentation capabilities. Two of the six loops have transient testing capabilities. The ATR has a capacity for up to nine water loops.
