Abstract:
Kartini Reactor in Yogyakarta is in operation for 28 years. In order to assure and maintain the safety of the reactor, ageing management program has been conducted. Inspection to the Reactor tank was conducted firstly in 2001, indicated that the tank has only minor defects. The origin of the two swelling features seen on the bottom tank indicated as S1 and S2 could not be verified, however they are not considered to be a serious issue for future safe operation. Kartini Reactor license was expired in November 2005. BAPETEN requirements was safety status of Kartini Reactor must be demonstrated well. Therefore re-inspection was conducted again in December 2005 and September 2006. Although swelling has been occurred on the bottom tank of Kartini Reactor as an ageing product of component and relatively constant in size after in operation for 28 years, Kartini Reactor tank in Yogyakarta is still in good and safe condition for continued operation.
