The temperature dependence mimics triple-$\\alpha$ nuclear reactions and the fluid geometry is a rotating spherical shell. These are key ingredients for the study of convective accreting neutron star oceans. A dimensionless parameter ${{\\rm Ra}}_n$, measuring the relevance of nuclear heating, is defined. We explore how flow characteristics change with increasing ${{\\rm Ra}}_n$ and give an astrophysical motivation.
