Abstract

Nowadays, nuclear power plants around the world produce vast amounts of spent fuel. After discharge, it
requires adequate cooling to prevent radioactive materials being released into the environment. One of
the systems available to provide such cooling is the spent fuel cooling pond. The recent incident at
Fukushima, Japan shows that these cooling ponds are associated with safety concerns and scientific studies
are required to analyse their thermal performance. However, the modelling of spent fuel cooling
ponds can be very challenging. Due to their large size and the complex phenomena of heat and mass
transfer involved in such systems. In the present study, we have developed a zero-dimensional (Z-D)
model based on the well-mixed approach for a large-scale cooling pond. This model requires low computational
time compared with other methods such as computational fluid dynamics (CFD) but gives reasonable
results are key performance data. This Z-D model takes into account the heat transfer
processes taking place within the water body and the volume of humid air above its surface as well as
the ventilation system. The methodology of the Z-D model was validated against data collected from
existing cooling ponds. A number of studies are conducted considering normal operating conditions as
well as in a loss of cooling scenario. Moreover, a discussion of the implications of the assumption to
neglect heat loss from the water surface in the context of large-scale ponds is also presented. Also, a sensitivity
study is performed to examine the effect of weather conditions on pond performance.
