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.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

CVD-tungsten coated Divertor Mock-UPS were fabricated and tested in an ion beam test facility in JAERI. The mock-up consisted of a 2 mm thick CVD-tungsten on a 30 wt% Cu infiltrated tungsten skeleton heat sink. For the thermal fatigue tests, the heat load of 15 MW/m2, 0.3 s was applied to simulate the bonding interface temperature under a steady heat load of 5 MW/m2. The mock-up successfully endured a heat load of 15 MW/m2, 0.3 s for more than 1000 thermal cycles. No cracks were observed at the bonding interface by optical microscope observation. Screening tests were also performed to evaluate the performance limit of the mock-up. The mock-up endured up to a heat load of 20 MW/m2, 10 s without failure.
