  Traces of the minimum and maximum values of temperature (\si{\kelvin}) or power density (\si{\watt\per\cubic\metre}) obtained from the coupled cylindrical flow through the core and the corresponding nodal value of the power density at the maximum temperature and the temperature at the maximum power density. The total power was \SI{3000}{\mega\watt}.
