The Nuclear Regulatory Commission is asking Exelon to step up its effort to guarantee the funding for the decommissioning of the Limerick nuclear facility.
When the time comes for the plant to shut down, it’ll have to be decommissioned. Exelon has more than $500 million to carry that out, but more recent estimates show decommissioning will cost upwards of $620 million.
Needless to say, that creates a problem for Exelon. According to the Mercury the NRC wants Exelon to begin discussing rate relief with the Pennsylvania Public Utilities Commission. Electric customers face rate hikes if Exelon still has a shortfall when it’s time to decommission.
Currently licenses for Limerick Units 1 and 2 expire in 2024 and 2029, respectively, but a 20-year extension is possible.
