National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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

DE2001757567

Publication Date	2000

Abstract	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.
