A year in orbit: ISS deployment tests radiation detectors for future space missions
The predawn darkness on a cool Florida night was shattered by the ignition of nine Merlin engines on a SpaceX Falcon 9 rocket. The thrust of the engines shook the ground miles away. From a distance, the rocket appeared to slowly rise above the horizon. For the cargo onboard, the launch was anything but gentle, as the ignition of liquid oxygen generated more than 1.5 million pounds of force. After the rocket had been out of sight for several minutes, the booster dramatically returned to Earth with several sonic booms in a captivating show of engineering designed to make space travel less expensive and more sustainable.

The opening plenary will reflect on the profound and lasting impact of the landmark Reactor Safety Study (WASH-1400), published in 1975. Widely regarded as a foundational milestone in the development of probabilistic safety assessment (PSA), WASH-1400 transformed nuclear safety analysis and inspired generations of research and practice. The session is dedicated to the memory of two of its principal architects, Norman Rasmussen and Saul Levine, and will feature reflections and insights from former contributors to the study, as well as students, colleagues, and experts who have built upon its legacy. Through personal memories and technical perspectives, the session will honor the study’s enduring influence on the PSA discipline.
