Atomic Meltdown

A nuclear reactor core stabilizer and containment field has failed unexpectedly and you, the technician, have to manually stabilize the atomic matter until containment field can be initialized. The containment walls will start enclosing around the atomic matter as the containment field is brought back online. However because the containment field is down, other random atomic matter is being project around the reactor core. The manual stabilizers have not been calibrated on schedule so they do not stabilize the atomic matter correctly which has resulted in the atomic matter to jitter around. If two pieces of atomic matter collide or if the atomic matter collides with the walls before the containment field has been initialized, then the whole nuclear reactor wild explode.
