Description

The high temperature ballooning and deformation behavior of the Zircaloy-4 cladded PHWR fuel pins was investigated. Transient heating experiments were performed in the 5 to 70 bar internal pressure range and 8 to 12oC/sec heating rates. Fuel pins internal overpressure combined with the elevated temperature caused fuel pin claddings to balloon and rupture. The burst data (burst pressure and burst temperature) was recorded while, burst strains, engineering hoop stress and area of burst opening was calculated. Microstructural examinations and SEM fractography were also carried out. This paper presents the details of the experimental procedure and the results obtained. (author)
