Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Exploring new ways of communicating to local stakeholders about the storage and transportation of nuclear byproducts
From Indian Point and Pilgrim to Fukushima and Monticello, 2023 put tritium water into the public spotlight as policymakers debated – and sometimes blocked – planned discharges. The federal government’s pursuit of a consent-based siting approach for interim storage facilities is raising the importance of communications and engagement on the storage and transportation of spent nuclear fuel across the United States. Meanwhile, the continued Russian occupation of Ukraine’s Zaporizhzhia nuclear power plant provoked a flurry of media speculation over the safety of nuclear waste storage. Join a panel discussion on lessons learned from recent experiences in communicating the “back end” of the nuclear fuel cycle and discuss what we can do to help cement the public’s consent.
