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 automated startup of a boiling water reactor (BWR) plant is discussed. A startup procedure and a logic representation of the operational guidance given in current BWR plants are examined. Based on these examinations, a knowledge representation of the sequential operations is proposed. Plant startup is a process in which various plant functions are brought in to establish an operational plant state. Based on this understanding, the relationships between plant functions can be used to deduce a BWR plant operation procedure. Finally, the proposed knowledge representation is evaluated using a prototype system, and it is shown that the representation is very effective in the startup of an automated BWR plant even if abnormalities arise during operation.
