The vacancy formation energy of zirconium has been calculated by means of a microscopic model which takes into account the electron-electron and electron-ion interaction. The result obtained is in reasonable agreement with the presently available experimental data. The connection between the vacancy formation energy and the basic mechanism for irradiation creep in this materials are discussed.
