Geologist: A geological fault in the mountain under which the proposed nuclear waste storage facility would be buried could, after a few thousand years, cause the contents to seep out or water to seep in  Since nuclear waste remains dangerous for up to 25, 000 years, such seepage would be disastrous
So we should not place a nuclear waste storage facility under this mountain until scientists investigate whether this mountain has any geological faults
The proposed facility was not initially intended to be used for the storage of nuclear waste.
