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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

The U.S. Nuclear Regulatory Commission has recently published a new Regulatory Guide 1.233 that endorses a DOE-industry initiative called the "Licensing Modernization Project" approach for a licensing framework for advanced non-LWR reactors. An NRC-sponsored project has been developing a recommended approach for fitting large external hazards such as large earthquakes and high winds into the LMP framework in a seamless way. This panel session will discuss the technical and regulatory elements of the proposed approach, ongoing work to try out the framework on a few sample problems, and issues with implementing it in a way that designers can use easily.
