Atomic Twister

Atomic Twister is a 2002 American made-for-television disaster film starring Sharon Lawrence and Mark-Paul Gosselaar which revolves around a series of tornadoes that damage a nuclear reactor in a small town in western Tennessee, in turn causing a near-meltdown at the plant.

Hellman-Klein's shift supervisor Corrine Maguire sets out to try and contact the Nuclear Regulatory Commission (NRC), while an operator, Neville erroneously shuts down non-vital systems, which include the electric pumps in an attempt to reduce power.

The nuclear reactor overheats, causing coolant to evaporate from the waste pool, threatening to expose radioactive material.

With no communications between the plant and the sheriff's department and the NRC, Neville decides to manually shut down the reactor himself in order to divert the reactor's coolant to the waste pool to buy the operators more time, taking full responsibility for ordering the staff to shut down the electrical pumps while Corrine is away trying to establish contact.

Deputy Sheriff Jake, a neighborhood friend of Corrine, and whose mother was killed by a tornado during his childhood, searches for Campbell and finds him on the road.

Mere minutes before meltdown, Jake helps the firefighters while Corrine hooks up the fuel and eventually manages to start the generator, restarting the pumps and allowing it to refill the waste pool.
