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.

Nuclear fuel cycle reimagined: Powering the next frontiers from nuclear waste
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
Conference on Nuclear Training and Education(CONTE 2023) Speaker
Mr. Mirsky has more than 47 years of experience in the nuclear industry. He is a Senior Technical Advisor in the NuScale Office of Technology working on micro-reactor designs and innovative applications for the SMR. Previously, he was the NuScale Licensing Manager in which he was responsible for directing U.S. Nuclear Regulatory Commission (NRC) review responses and interactions for the NuScale SMR Design Certification Application (DCA), Nuclear Energy Institute (NEI) interface, and oversight of all NuScale Rockville office activities. The NRC approved the NuScale SMR DCA in August 2020. He has worked for Science Applications International Corporation (SAIC) and NUS Corporation consulting for U.S. and foreign nuclear power plants, DOE, and the NRC and at the Baltimore Gas and Electric Company (now Constellation) and Virginia Power and Electric Company (now Dominion Power) supporting the safety analysis, design, operation, licensing, and analysis of the Surry, North Anna, and Calvert Cliffs nuclear power plants. He holds an M.S. in Nuclear Engineering, a Bachelor of Engineering in Mechanical Engineering, and is a licensed Professional Mechanical Engineer in the State of Maryland. Mr. Mirsky has authored over 100 papers and reports as well as five patents.
