“…Among them, the Stefan model, combined with appropriate closure relations for the mass convection within the gas phase, yields accurate predictions of evaporation flow rates for a wide scope of configurations, including those reached during a SFP-LOCA [11]. Measured data on pool temperature and water loss for the SFPs at the Fukushima Daiichi nuclear power station after the 2011 accident have been used for validating the models [10,12]. The results suggest PHENOMENA IDENTIFICATION AND RANKING TABLE that bulk boiling does not necessarily occur in an SFP with inoperable cooling system if the heat load is low and the pool building well ventilated, since heat removal by evaporation becomes significant at pool temperatures well below the boiling point.…”

The OECD is a unique forum where the governments of 36 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisation provides a setting where governments can compare policy experiences, seek answers to common problems, identify good practice and work to co-ordinate domestic and international policies.

Calculation of evaporation is needed in many applications including swimming pools, water reservoirs, nuclear fuel pools, pools for rejection of heat from refrigeration systems, process tanks, etc. Hence accurate methods for prediction of evaporation are needed. Many prediction methods have been published including analytical models and empirical correlations. In the present study, 18 published prediction methods are compared to a very wide-ranging database which includes data from laboratory scale studies, swimming pools, and fuel pools in nuclear power plants. The data are from 25 sources. The range of data includes air temperatures from 6°C to 200°C, water temperatures from 7.1°C to 94.2°C, relative humidity from 0.21% to 98%, and air velocity from 0 to 8.5 m/s. The accuracy of prediction methods is examined for conditions in which natural convection dominates, that in which forced convection dominates, and that in which natural convection is absent. The results are reported and discussed. Recommendations are made for application.
