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.

President's Profile Steven Arndt: Prioritizing participation and advocacy
Steven Arndt began his one-year term last month as president of the American Nuclear Society, bringing the same high level of energy, investment, and action he has exhibited throughout his career. Reflecting on a life spent improving nuclear safety and technology, he notes that it’s not just the work; it’s also about the people and building connections and relationships. Arndt fondly recalls Peter Lyons, former NRC commissioner, assistant secretary of energy for nuclear energy, and ANS board member who passed away in April 2021. “I have been incredibly lucky to know and work with some great people in our field, and almost to a person they have been like Pete Lyons,” Arndt said. “They have been gregarious, outgoing, and supportive.”

The Hydrogen Intermediate and Peak Electrical System (HIPES) is a new proposed system that uses low-cost off-peak electricity or base-load nuclear energy to economically produce electricity for peak electrical demand, spinning reserve, and power regulation. HIPES has three major subsystems. Hydrogen and oxygen are produced from water using (a) off-peak electricity by methods such as electrolysis or (b) steady-state hydrogen production methods such as nuclear-hydrogen production with thermochemical cycles. The two gases are stored in large underground facilities using the same technologies used for the seasonal storage of natural gas. Peak electricity is produced by an advanced steam turbine with a burner that combines stored H2, O2, and water to produce high-pressure 1500°C steam, which serves as feed to a special high-temperature steam turbine with actively cooled blades. The steam plant efficiency is ~70%. HIPES power outputs can be rapidly varied to match changing electricity demand because the slow-response component of a traditional steam system (the boiler) has been eliminated. The economics are based on (a) the low cost of large-scale underground gas storage, (b) a low-capital-cost efficient method to convert hydrogen and oxygen into peak electricity (no steam boiler), and (c) the large differences in the prices of base-load and off-peak power relative to the premium prices paid for peak power production, spinning reserve, and power regulation. The technology, markets, and economics are described.
