Assessment of U. S. domestic capacity for producing reactor-grade thorium dioxide and controlling associated wastes and effluents

PDF Version Also Available for Download.

Description

Demand for reactor-grade ThO/sub 2/ is likely to increase as a result of the growing interest in the application of the thorium-uranium fuel cycle to nuclear reactors. The wastes and effluents identified with the production of ThO/sub 2/ from monazite sand are waste water, tailings, dust, smoke and gas, and radionuclides (primarily, /sup 232/Th and /sup 226/Ra). There are currently an estimated 1,500 short tons of crude thorium hydroxide byproduct that can be readily converted to reactor-grade ThO/sub 2/. The present maximum domestic capacity for producing reactor-grade ThO/sub 2/ is about 65 to 100 ton/year. The current domestic capacity for ... continued below

Description

Demand for reactor-grade ThO/sub 2/ is likely to increase as a result of the growing interest in the application of the thorium-uranium fuel cycle to nuclear reactors. The wastes and effluents identified with the production of ThO/sub 2/ from monazite sand are waste water, tailings, dust, smoke and gas, and radionuclides (primarily, /sup 232/Th and /sup 226/Ra). There are currently an estimated 1,500 short tons of crude thorium hydroxide byproduct that can be readily converted to reactor-grade ThO/sub 2/. The present maximum domestic capacity for producing reactor-grade ThO/sub 2/ is about 65 to 100 ton/year. The current domestic capacity for producing reactor-grade ThO/sub 2/ is sufficient to sustain a thorium-uranium fuel cycle of up to 11,000 MW(e) without recycling thorium, depending on the mix of reactor types selected. This range can be increased to 28,000 MW(e) by expanding ThO/sub 2/ purification capacity to match the current production rate of crude thorium byproduct. Potential constraints identified which may impact the expansion of domestic ThO/sub 2/ production are (1) uncertainty in the marketplace, (2) limited available thorium for production of reactor-grade ThO/sub 2/, (3) limited production capacity, and (4) mounting public concern over current levels of radioactivity detected at various points in the production process of thorium and uranium products.
