for 60 years.
Borssele's life extension means it will produce more nuclear waste then was initially foreseen, and this is why the Dutch government also granted an expansion of the COVRA intermediate nuclear waste storage early 2015.
Laka Foundation appealed the expansion of the COVRA nuclear waste storage in February 2015. One of the objections of Laka c.s. is that the (interim) storage of nuclear waste at Covra is expanded without there being a plan what to do with the nuclear waste after closure of the Covra. There is a national fund which should collect enough interest to finance eventual construction of a final repository around 2100 and there's a tentative research program which is planned to last until 2100. And that's it.
