ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Fuel Cycle & Waste Management
Devoted to all aspects of the nuclear fuel cycle including waste management, worldwide. Division specific areas of interest and involvement include uranium conversion and enrichment; fuel fabrication, management (in-core and ex-core) and recycle; transportation; safeguards; high-level, low-level and mixed waste management and disposal; public policy and program management; decontamination and decommissioning environmental restoration; and excess weapons materials disposition.

How will you celebrate Nuclear Science Week?
It’s the third week of October, and Nuclear Science Week, first recognized in 2009, has arrived! Nuclear Science Week is an annual opportunity to celebrate nuclear science; recognize the professionals who apply it to solving the world’s most pressing problems; encourage nuclear professional development and networking; and share information with students, educators, and community members about the vital role of nuclear science in the lives of all people.

The fueling unit energy cost of various thorium-based fuels and uranium-based fuels augmented by small amounts of thorium in a pressure tube heavy water reactor (PT-HWR) are assessed building upon previous studies. The results suggests that fuel concepts using slightly enriched uranium augmented by thorium and thorium mixed with low-enriched uranium can be cost competitive and have the greatest potential for near-term implementation in PT-HWRs. Thorium-based fuels that contain small amounts of recycled plutonium or 233U will require more effort to identify and develop technologies to reduce the costs of reprocessing and fabrication for these fuels. However, as an alternative nuclear fuel for reliable and sustainable low-carbon electrical energy generation, all thorium-based fuels are competitive for both short-term and long-term implementation.
