Perpetual Atomics Ltd, QSA Europe (a trading name of Loma Systems s.r.o.), QSA Global, Inc., and Reef Origin have signed an MOU to collaborate on the industrialized production of radioisotope power systems in Europe. The partnership will initially focus on Radioisotope Heater Units (RHUs) and aims to expand the capability based on market demand. This development builds on Perpetual Atomics' existing work and recent announcements regarding European americium supply chain agreements.

Why it matters

Radioisotope and nuclear power technologies are recognized as essential for a range of operational scenarios in space, including in-space resource utilization. This collaboration aims to establish a European production capability for these critical power systems to support the growing space economy.

The details

The key partnership with QSA Europe provides access to existing facilities, capabilities, knowledge, and know-how for the storage, handling, and distribution of commercial radioisotope systems for terrestrial applications, which is directly transferable to radioisotope power technologies for space. This first step will address the assembly of RHUs in Europe at scale, with the aim of expanding this capability based on market and customer requirements.

  • The MOU was signed in Prague in February 2026.
  • Perpetual Atomics is planning a 2024 launch.
