Mushroom clouds are not the defining characteristic of a nuclear explosion. All explosions that are large enough create a mushroom cloud.
A nuclear explosion will have gamma rays and x rays. The light would be more blinding than the arc of a welder. There will be an intense blast wave moving at supersonic speeds.
This wasnt even close to what a nuclear explosion would look like from that close. Not even if was the size of an artillery shell.
