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.

Nu-HOPE (Nuclear-Highly Optimized Prandtl number Experiment facility) is a newly built facility in UNIST to simulate molten salt reactor. Due to the high-temperature corrosion and toxicity issue, the heat transfer phenomena of molten salt are studied under similarity technique with high-Prandtl number simulant fluid. 12-meter-high Nu-HOPE was designed for the study of both natural and forced circulation of high-Prandtl number fluid. Experimental results of natural and forced circulation can give the evaluation of heat transfer characteristics and fluid stability model for the simulant molten salt. In this paper, design of Nu-HOPE based on numerical approach to developing heat transfer model of high-Prandtl number fluid is suggested.
