Delayed hydride crack growth study on irradiated Zr–2.5Nb pressure tube

Delayed hydride crack (DHC) growth study was carried out on irradiated Indian Zr–2.5Nb pressure tube which had seen around 8 effective full power years of operation. Disc compact tension type specimens were used for the DHC tests at 210°C, 250°C, 265°C and 290°C. This paper discusses the test method...

Zusammenfassung:Delayed hydride crack (DHC) growth study was carried out on irradiated Indian Zr–2.5Nb pressure tube which had seen around 8 effective full power years of operation. Disc compact tension type specimens were used for the DHC tests at 210°C, 250°C, 265°C and 290°C. This paper discusses the test methodology, results generated and compares it with that obtained on the as-fabricated pressure tube of similar specification.
