Thermodynamics, reversibility, irreversibility, energy, entropy, relativity, Einstein’s relation
Contrasting with its widespread use in the study of ordinary chemical reactions, the thermodynamic tool remains little solicited in the study of nuclear reactions. This situation is certainly due to the fact that the principle of mass conservation has been for a long time the fundamental basis of chemical thermodynamics. Although the need of its substitution by the principle of energy conservation is now totally admitted, the insertion of this last one into the major thermodynamic equations has not yet been done. After a brief recall of a hypothesis that takes into account the problem, the aim of this paper is to ask a question about the precise thermodynamic interpretation that can be suggested for nuclear reactions.
