The Nuclear Regulatory Commission has declined to
approve a portion of Westinghouse's AP1000 reactor design because an important component might not withstand such natural disasters as earthquakes and tornadoes. The move increases the possibility of delays in the construction of 14 reactors across the country, particularly two twin-reactor ventures in South Carolina and Georgia. The company, a unit of Toshiba, vowed to perform tests immediately to meet the agency's standards.
