[DC comics] Why does the Justice League even bother teaming up with Captain Atom?

Captain Atom has a notorious weakness: if his suit gets torn, he creates a nuclear explosion upon being forced out of it due to his living nuclear energy status. This has been repeatedly shown to be a huge threat to him, his fellow team members, and the world. Given that, why does the Justice League let him come along on missions? They have Firestorm to do the nuclear energy related work. They've got plenty of flying people and strongmen. Plenty of people can shoot projectiles both energy and non-energy based. Isn't he just a liability?

This problem only exists in the universe where the Justice League Unlimited exists.

Quite honestly, it takes extreme force, on the order of the kind of force that can harm Wonder Woman or Superman, to actually tear his suit. 

Most forces the JLU faces just isn't at that level. On the other hand, his abilities are quite useful, he's very powerful, and as an active duty military officer he is experienced in both combat tactics and command.

He's an excellent field commander, and a powerful, versatile asset in a fight.

In the New 52 universe, his suit is made of Dilustrel and is nearly invulnerable. if it is breached he doesn't explode, he Quantum Jumps, a totally different effect.
