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.

One of the key objectives of the CFAR (compact fusion advanced Rankine) cycle concept for advanced tokamak reactors is to reduce the capital costs of the power conversion system and the balance of plant. A design of the heat rejection system has been done as part of a preliminary cost study in order to evaluate the capital costs of this fusion power plant concept. This system has been optimized to yield the minimum capital cost subject to constraints on the size of the desuperheater/condenser heat exchangers, the pressure drops and the pumping power required for the heat-rejection coolant. The results of this study including estimates of the cost of electricity for the CFAR concept with and without a bottoming plant are reported.
