Perpetual Atomics Ltd has signed a collaboration agreement with QSA Global, Inc., based in the USA, to process americium into sealed sources for radioisotope power systems. This transformative technology, harnessing nuclear material for space applications, is poised to power an array of new space missions.

Perpetual Atomics is excited to announce this collaboration, which will enable the processing of americium into sealed sources for use in radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs). This partnership is another step toward supporting sustainable and reliable power solutions for some of the most challenging environments in space.

A spinout from the University of Leicester, Perpetual Atomics leverages over 20 years of expertise in space nuclear power systems, space science, and space exploration. The company aims to provide innovative solutions to space mission power challenges, ensuring sustainability and reliability in extreme environments, including the capability to "survive the night."

QSA Global, with its extensive expertise in designing and producing commercial radioisotope sealed sources for industrial use in the harshest terrestrial environments, is an ideal partner. The company's infrastructure and experience make it a perfect collaborator as Perpetual Atomics expands its US presence.

Professor Richard Ambrosi, CSO, founder, and Director of Perpetual Atomics, said, “The team and facilities at QSA Global are unique, and there is strong alignment in both the practical philosophy and approach of the two organizations. We look forward to growing our collaboration to support future space science, exploration, and commercial missions.”

Dr. Joe Lapinskas, Director of Innovation at QSA Global said: “We’re thrilled to bring our decades of expertise in radioisotope sealed sources to this groundbreaking collaboration with Perpetual Atomics. Combining our strength in robust source design with their pioneering advances in space nuclear technology, we’re opening doors to unprecedented possibilities for powering space exploration and science missions.”

Building on Perpetual Atomics' recent launch at the IAC meeting in Milan, this collaboration underscores the company's commitment to integrating technology, strategic partnerships, and innovation at the core of its operations.

Perpetual Atomics’ mission draws on two decades of development in radioisotope power systems led by the Space Nuclear Power group at the University of Leicester.

Piers Slater, Reef Global Executive Chairman & Chief Executive Officer of Perpetual Atomics, commented, “We are very excited about the collaboration with QSA which we believe will be transformational for both nuclear power solutions in space and Perpetual Atomics as we move at pace from a spin out to a commercial trading entity delivering our products at scale.”
