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.

Tank waste operations resume at Idaho’s IWTU
The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

The modular high-temperature reactor (HTR-M) is characterized by the use of standardized reactor, heat transfer, and loop components. One or more primary circuit units make up the nuclear steam-generating system (or heat-generating system) of a HTR-M power plant. The core of the helium-cooled HTR-M consists of a randomly packed bed of spherical fuel elements (pebble bed reactor). The characteristic design of the HTR-M core ensures that permissible core temperatures are not exceeded, even if all cooling systems fail. Today, HTR-M power plants can already be applied in the combined generation of electricity, process steam, and/or district heat. In the near future the HTR-M can be used as a heat source for processing plants in the chemical industry, e.g., for methane cracking, coal gasification and similar chemical processes.
