The Murmansk Initiative-RF (MI) was conceived to provide the Russian Federation (RF) with the capacity to manage low-level liquid radioactive waste (LLRW) and comply with the requirements of the London Convention that prohibit ocean dumping of these wastes. The Initiative, under a trilateral agreement begun in 1994/95, has upgraded an existing low-level liquid radioactive waste treatment facility, increased its capacity from 1,200 m3 /year to 5,000 m3 /year, and expanded the capability of the facility to treat liquids containing salt (up to 20 g/L). The three parties to the agreement, the Russian Federation, Norway, and the United States, have split the costs for the project. It was the first project of its kind to utilize exclusively Russian subcontractors in the upgrade and expansion of the LLRW treatment plant on the premises of FGUP Atomflot (now FGUP Atomflot) in Murmansk, Russia. The project advanced into the test-operation phase. These start-up activities have include d processing of actual radioactive liquid waste from the Arctic icebreaker fleet, and incorporation of these wastes into a cementation process of Russian design. Initial runs have revealed that procedures for unloading spent ion-exchange sorbents need to be improved and that sludges formed during removal of alkaline-earth metals should be compacted in order for the facility to operate at its full potential. These issues needed a substantial amount of work but have now been resolved, and progress on the final critical phases of the project, including Russian licensing activities will be reported. Discussions will also report on any modifications to the proposed operational schedule or protocols for the now operating facility. ''Lessons Learned'' over the six years of construction through operation are evaluated and discussed.
