Verification of physics predictions for GT/AD-MHR core designs.

[摘要] A gas-cooled transmitter, that would be configured successively as a critical gas-turbine and an accelerator-driven modular helium cooled reactor (GT/AD-MHR), has been proposed by General Atomics as an alternative to the heavy-metal coolant transmuter in the USDOE Accelerator Transmutation of Waste (ATW) project. In the evolving design, an outer thermal-spectrum core zone and an inner fast-spectrum core zone also containing a spallation neutron-source target are employed for very high destruction rates of the plutonium isotopes contained in recycled LWR-discharge or weapons-grade fuel. Fuel initially burned in the thermal zone for up to 3 years and subsequently reconstituted is transferred to the fast-core zone for additional burning of the higher actinides, to obtain nearly complete plutonium destruction.
