this well had been burning nonstop for three years. >> they said the gas flame was so high, it could be seen 50 miles away. >> reporter: watch as the nuclear device detonates. a shock wave rattles the earth, moments later, the flame extinguishes and the well is finally sealed. >> the shock wave would initially melt the rock and then it would crush the rock and then it would compress the rock so it would be compressed completely shut. >> there really isn't any certainty that doing this kind of a detonation under the water and in this particular geologic situation would work. >> reporter: a nuclear option to plug the well is downright laughable says nathan holtman who has studied civilian nuclear power. >> there's questions about radiation leakage, damaged eco systems, questions about the impact of a shock wave. >> reporter: but because of where the nuclear device would be placed, he disputes concerns about radiation release or damage to wildlife.
