Extreme wind loading is applied to structures using methods and procedures consistent with ANSI Building Code A58.1- 1972. Data, formulas, and procedures for determining maximum wind loading on structures and parts of structures are included. In 1998 the Davis-Besse Nuclear Power Plant in Ohio was hit by an F2 tornado, which damaged the switchyard and communications and forced the plant into automatic shutdown after external power was lost. The savage storms in that passed through parts of Alabama, Mississippi, Tennessee and Virginia on Wednesday knocked out power to the Browns Ferry nuclear power plant… The protection of nuclear power plants for the effects of tornadoes (or extreme winds from typhoons or hurricanes, depending on the locality) is required through 10CFR50 Appendix A, General Design Criterion 2 which requires that structures, systems, and components (SSCs) important to safety be designed to withstand the effects of natural Tornado-strikes-nuclear-plant was the subject of the movie "Atomic Twister" with catastrophic results. The tornado hazard has been assessed for a nuclear power plant located in the Southeast China in this paper. General Design Criteria – The protection of nuclear power plants from the effects of tornadoes (or extreme winds from typhoons or hurricanes, depending on the locality) is required through 10CFR50 Appendix A, 10 CFR 50, Appendix A, General Design Criterion 2 which requires that structures, systems, and components (SSCs) important to … Tornado is one of the most hazardous external natural events which should be taken into account in the siting, design and safety evaluation of nuclear power plants. The staff of a nuclear reactor must struggle to avert a disaster when tornadoes cause damage that threatens to start a meltdown. Inspections triggered by Japan's nuclear crisis found that some emergency equipment and storage sites at the Wolf Creek nuclear plant in southeastern Kansas might not survive a tornado. With Sharon Lawrence, Mark-Paul Gosselaar, Carl Lewis, Jonathan Blick. Plot. WASHINGTON (AP) — The closest nuclear power plant to tornado-ravaged Joplin, Mo., was singled out weeks before the storm for being vulnerable to twisters. The closest nuclear power plant to tornado-ravaged Joplin, Mo., was singled out weeks before the storm for being vulnerable to twisters. Nuclear power plants are now designed to withstand the one-in-ten-million EF5 tornado with 230 mph wind speed and a 1.2 psi rapid pressure decrease in … Directed by Bill Corcoran. Road Map of Regulatory Requirements. Packing winds of more than 261 miles per hour, the strongest tornado in Maryland's history passed within an estimated two miles of the Calvert Cliffs Nuclear Power Plant in Calvert County on Sunday. Nuclear power plant design criteria for tornadoes and extreme winds are presented. 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.
