The RAIN scale: A good intention that falls short
Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.
Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.
Advanced Reactor Safety (ARS) SPeaker
Eric Williams is the Senior Vice President & Design Authority at TerraPower. In this role, he oversees the engineering associated with TerraPower’s advanced reactors and medical isotope programs. He works closely with the senior program managers to provide design, analysis and testing to meet project objectives. Williams has 22 years of experience in engineering and has spent the last 15 years developing nuclear power plant designs, with an emphasis on safety.
Before coming to TerraPower, Williams spent four years at B&W mPower developing a new small modular reactor design and worked to develop the safety of the plant and take the design through pre-licensing with the U.S. Nuclear Regulatory Commission. He also led the development of an Integrated Systems Test facility, which was a small-scale, electrically powered version of the nuclear power plant used to demonstrate the safety characteristics of the plant during simulated accident scenarios.
Earlier in his career, Williams worked on another new reactor design where he led a team that analyzed severe accidents. He developed the analysis and documentation needed to license the design and took the severe accident analysis through the licensing process.
Prior to working on new nuclear reactor designs, Williams worked on making the current fleet of nuclear power plants in the U.S. more efficient by upgrading their equipment and modernizing their systems. He worked directly with electric power utilities and visited operating nuclear power plants to understand the issues they faced and helped develop solutions.
Williams holds a Bachelor of Science in Mechanical Engineering from the University of Florida, a Master of Business Administration from Lynchburg College and a Professional Engineer license.
