The Japanese government plans to scrap the prototype fast-breeder reactor Monju, which has been hit by a number of safety problems.
The government is set to make the final decision on the fate of the reactor in Fukui Prefecture next month.
Officials say they've obtained results and knowledge to a certain degree to develop a demonstration reactor, which is the next phase.
They also say resuming operations of Monju would cost a huge amount of money.
The officials estimate that retrieving spent nuclear fuel will take at least 5-and-a-half years, and completing the whole decommissioning work will require 30 years.
The government is considering designating the region that hosts Monju as one of the centers for research and development of fast reactors.
It also hopes to conduct studies on liquid sodium, which is used to cool fast-breeder reactors, on the sidelines of Monju's decommissioning work.
Monju has operated for just 250 days since it began operations in 1994.
