Hydride cracking in Zirconium alloys is one of the major causes of failure and considering the importance of this type failure we have reviewed the situation that makes Zirconium alloysvulnerable to cracking. The results show that most of atomic hydrogen is produced in normal corrosion process albeit; absorption depends on various factors. The recent investigationsrevealed that, radial hydrides are more disastrous compared to circumferential hydrides.
