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.
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.

Ensuring a role for nuclear in the response to climate change
Nuclear power is an important tool in the response to climate change, and advanced reactors may offer advantages over existing plants in providing carbon-free generation at the scale necessary to respond to the existential challenge that climate change presents. The International Atomic Energy Agency is aggressively addressing issues related to the possible transition to advanced reactors. This letter is to urge a redoubling of effort by Member States to put in place the necessary capabilities to deal with the challenges that they present.

The China lead-based research reactor (CLEAR-I) with 10 MW(thermal) will be built for the research of the accelerator-driven subcritical system (ADS) and lead-cooled fast reactor technology. Compared with other reactors, ADS has a spallation target placed in the reactor core center, which affects the refueling motion in the vessel. It is difficult to reach the fuel assemblies near the proton beam tube through the common vertical refueling gripper. In this technical note, a new cantilever-type and internal grasping gripper with defined refueling process was designed to handle all assemblies in CLEAR-I. The static and kinematics analyses of the gripper were carried out by ANSYS Workbench and MATLAB considering the influence of working in air and liquid metal. The structural and kinematic simulation results show that the design of the gripper is feasible for CLEAR-I. It provides an advanced refueling solution for the technical validation of ADS.
