About

Deep Isolation offers an innovative solution to secure and dispose of spent nuclear fuel from commercial nuclear reactors. Our horizontal drill hole technology offers both safety and low cost. While the drilling technology is standard, Deep Isolation is the first company proposing to use this method for the safe isolation of spent nuclear fuel under a billion tons of rock that has demonstrated geologic stability and impermeability.
