    This paper discusses the regular inspections of the Kartini reactor tank liner as part of the ageing management program. Kartini reactor is located in Yogyakarta, in Indonesia. The aim of the regular inspections is to assess the reactor tank condition as part of the ageing monitoring program to ensure safe operation of the reactor. The reactor was inspected utilizing a series of non-destructive inspection methods between 2001 and 2006. One of the inspection results was the detection of two swelling features seen on the bottom of the reactor tank. Kartini reactor has been in operation for 28 years and the observed swelling has been monitored over the past 5 years. The regular measurements and observations show that the swelling has stopped increasing in size and has now reached a stable size. After assessment and analysis of the cause of the swelling the reactor is considered to be in good condition and safe for future operation. © The Authors
