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.

Alternate Chair:
Massimiliano Fratoni
This panel will discuss topics related to the initial test program for first-of-a-kind (FOAK) advanced reactors. Dr. Sam Bays will provide a historical overview of past advanced reactor test programs as documented in his team's report, "Startup Physics Testing of Advanced Reactors - A Historical Review". Dr. Bays and Dr. Abe Weitzberg have co-chaired the ANS working group, Initial Fuel Loading and Startup Physics Tests for FOAK Advanced Reactors, ANS-19.13. Current findings of ANS-19.13 will be discussed. Dr. Nader Satvat of Kairos Power will be providing an overview of current test plans for the HERMES reactor. Mr. Mike Prible of Westinghouse will provide his perspectives leading the startup physics testing of AP1000 pressurized water reactors.
