The final goal of this project is to complete the decommissioning of the Korean Reaearch Reactor #1 & #2(KRR-1 & 2) and uranium conversion plant safely and successfully. The decommissioning the five incidental facilities was successfully carried out and the scoping survey and characterization survey of radioactivity on KRR-1 & KRR-2 site were proven as basic steps for the final evaluation of the residual radioactivity and assessment of the rehabilitation of the KRR-1 & KRR-2 site in 2008. this works, the FSSR(Final Status Survey Report) will be submitted to the regulatory body for the release of the site from the regulation in 2009. nuclear facility is now in its closing stages. After The first decommissioning project of a domestic The decommissioning for nuclear facility may demand the high technologies, remote control equipment and radioactivity assessment. So the developed technologies and the obtained experiences could be applied to new decommissioning projects of the nuclear facilities in the future, including north Korea nuclear facilities. At the decommissioning site of the uranium conversion plant, the decontamination of the stainless steel waste was performed and the all the sludge of the lagoon-2 waste was completely treated in this year. The technologies and experiences obtained from the UCP dismantling works are expected to apply to other fuel cycle facilities. The lagoon sludge treatment technology was the technology firstly tried in actual decommissioning sites in Korea and it is expected that this technology could be applied to other country.
