      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.

Disposal of HLW and SNF: Shall we dispose of it before 2050?

March 17, 2021|12:00–1:30PM (1:00–2:30PM EDT)

ANS Members, please log in to watch this webinar.


Radioactive waste is handled responsibly, safely, and securely around the world, though delays in taking the final step toward disposal of high-level wastes is still, generally, decades away. Important progress is being made in several countries, in particular Finland, Sweden, and France are moving forward towards the realization of such disposal facilities and countries like Belgium and Switzerland are following closely behind. Most other countries are trailing by more than two decades, as only generic designs for such disposal facilities are available, and the process towards the identification of a disposal site is yet to be started (or restarted).

This webinar provides an overview of the current progress and status of such disposal programs globally and the technical, socio-political, and regulatory timelines associated with such disposal facilities. The webinar also address the more recent considerations for a more integrated waste management policy seeking to optimize the overall management of all radioactive wastes requiring disposal.
