Nucleotic Escape

Reactors are always risky, posing a threat of going unstable and exploding at any given moment.
You're trapped with one such reactor and your only hope of escaping is to fill up the reactor with water or perish in the explosion.
You're a semi - unstable character who needs to navigate to the lever using boxes and chains. Pulling on the lever releases the water , which in turn defuses the reactor . Hence moving on to the next level.
