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.

The main passive safety system of the Molten Salt Fast Reactor (MSFR) is a cold plug, placed in the bottom of the reactor. In case of an uncontrolled temperature rise in the reactor core, this plug melts, allowing the draining of the molten fuel salt towards a safe configuration. In the present paper, the main physical phenomena occurring in the MSFR during the draining process is presented. Then, a physical model for simulating the draining process is introduced. This model is then used for analyzing different draining scenarios. Finally, the velocity and temperature fields obtained for this scenarios are analyzed in the light of safety considerations.
