Two steps forward for U.K. advanced nuclear
This week, two significant announcements have emerged from the United Kingdom’s advanced reactor sector.
On June 14, Rolls-Royce, the United Kingdom National Nuclear Laboratory, and the Japan Atomic Energy Agency announced that they had signed two trilateral memorandums of cooperation to collaborate on “advanced modular reactor (AMR) technology, specifically high-temperature gas-cooled reactors (HTGR), and the coated particle fuel these reactors will use.”
Separately, on June 16, Bellevue, Wash.–based TerraPower announced that its Natrium reactor design has been formally submitted for U.K. regulatory review. The company also announced the formation of a new subsidiary, TerraPower UK Ltd.

Idaho National Laboratory (INL) is hiring an Associate Laboratory Director (ALD) for the Advanced Test Reactor (ATR) to join our senior leadership team.
ATR is not just a reactor; it is one of the most consequential scientific instruments in the world. Operating at up to 250 MW with unmatched thermal neutron flux and a uniquely flexible cloverleaf design, ATR is the nation's highest-capacity test reactor and a unique national capability with validated mission need through at least 2085. It is the backbone of the U.S. Navy's Naval Reactors program, a critical platform for advanced fuel qualification and next-generation reactor development, and a key enabler of NASA's space propulsion and isotope production missions. No other facility in the world does what ATR does, and the work conducted here directly shapes the future of nuclear energy, national security, and space exploration.
Leading ATR means leading at the intersection of science, strategy, and national mission. The ALD for ATR provides visionary scientific leadership, operational excellence oversight, and strategic stewardship across ATR and supporting R&D infrastructure. Central to this role is the faithful stewardship of ATR's world-leading capabilities—ensuring the reactor operates consistently, reliably, and at the highest levels of performance so that its scientific mission is never compromised. This is a rare opportunity to serve as the leader of a world-class enterprise at a pivotal moment: modernizing a premiere national asset, inspiring a multidisciplinary workforce, and ensuring that ATR remains the global standard-bearer for irradiated materials and nuclear fuels research for generations to come. As a senior member of INL's Laboratory leadership team, the ALD will help shape not only the future of ATR, but the trajectory of the Laboratory and the nation's nuclear and national security enterprise.
This position reports directly to the INL Laboratory Director.
