Abstract
The main task of every nuclear power plant owner is to establish the balance
in taking precautions such as monitoring, inspection and corrective actions,
with the aim of retaining the steam generator integrity. The steam generator
integrity assessment presents the key factor in achieving the mentioned aim.
It is necessary to conduct a wide range of researches for a quality of steam
generator integrity assessment. One of the key elements as well as starting
point for steam generator structural integrity assessment is establishing
burst pressure relationship for each degradation mechanism orientation,
type and their location on steam generator tubes. This paper presents the
role of burst pressure relationship within VVER steam generator structural
integrity assessment and its determination. In addition to this, the results of
researches for the axially oriented flaws on the free span will be presented,
with the aim of establishing burst pressure relationship.
