摘要：
Hydrogen diffuses in zirconium alloys in response to gradients in hydrogen concentration, temperature, and stress. This essay discusses the results of several evaluations of the coefficient describing the effects of temperature gradients called the heat of transport. The values distinguish between when hydrogen is in solution, (25 +/- 3) kJ/mol, and when stable hydrides are present, (116 +/- 17) kJ/mol.
