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. The film originally premiered on TBS Superstation on June 9, 2002. Plot A series of tornadoes cripple Hellman-Klein Nuclear Power Plant in Basset County, West Tennessee by damaging a power transformer and a generator, killing the plant's security guard Stu (Carl Lewis) in the process, and leaving the plant with very little power to operate. Hellman-Klein's shift supervisor Corrine Maguire sets out to try and contact the NRC, while an operator shuts down non-vital systems, which include the electric pumps to reduce power. Just then, a second tornado hits the plant, damaging the diesel pumps, losing almost all controls. Meanwhile, Campbell Maguire (Daniel Costello), the plant's shift supervisor's 12-year old son, is caught in the twisters. His babysitter, Stacy is killed and he runs away towards the plant on his bike. When the diesel pumps fail, the staff try to restart the electric pumps, but they won't respond. The nuclear reactor overheats, causing coolant to evaporate from the waste pool, threatening to expose radioactive material. The staff attempt to initiate SCRAM procedures to try to shut down the nuclear reactor, but the computer fails to respond. With no communications between the plant and the sheriff's department and the Nuclear Regulatory Commission; leaving them on their own, Corrine, Potter, and Neville venture inside the containment room to shut down the reactor manually, but radiation leakage prevents them from doing so. Neville (John Summer) 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 them to shut down the electrical pumps while Corrine is away trying to establish contact. He successfully does so, but is now locked himself inside the containment room. A Deputy Sheriff named Jake (Mark-Paul Gosselaar), a friend of Corrine, and whose mother was killed by a tornado during his childhood, searches for Campbell and finds him on the road. Together they make their way to safety at Corinne's request. On the way they discover Jake's girlfriend, Ashley (Charmaine Guest), trapped on a steep hillside in her car. Jake goes down to rescue her. Both Jake and
