We point out that a recent model for the heat capacity of alpha-U that invokes CDW collective modes is unphysical. We show instead that the features in the heat capacity of both single-crystal and polycrystalline alpha-U can be accounted for by a number of Peierls transitions that are subject to increased disorder in the polycrystalline sample.
