Management Of Decommissioning Waste

>

At present Indonesia has 3 research reactors namely the 30 MW MTR type multipurpose reactor in Serpong the 2000 kW TRIGA MARK II reactor in Bandung and the 250 kW TRIGA MARK reactor in Yogyakarta. A comprehensive feasibility study and site investigation of the first NPPs had been undertaken from 1991-1996. The Muria Peninsula was selected as a suitable site to accommodate several NPPs with a total capacity of 7000 MWe. However, NPPs will only be in operation not later than 2016. The TRIGA MARK II reactor in Bandung achieved its first criticality in 1965 at a power level of 250 kW. This reactor was then subject to a power upgrading to 1000 kW in 1971. In October 2000 the reactor again was up-graded to 2000 kW. So, this Bandung TRIGA MARK II Reactor tatally has been operating for 38 years and will be an object for the near future-decommissioning program. The up-grading process has generated dismantling waste such as reflector, heat exchanger, pipes etc. at sufficient amount and weight (close to 22 tons). In this study strategy for the management of such waste such as waste inventory, classification as well as implementation plan has been developed. In this paper we discuss the present status of the research reactor decommissioning program in Indonesia related to the management of radioactive waste generated there from. Mulyanto
