The Nuclear Regulatory Commission unanimously approved a radical new reactor design on Thursday, clearing away a major obstacle for two utilities to begin construction on projects in South Carolina and Georgia. The decision, a milestone in the much-delayed revival of plant construction sought by the nuclear industry, involves the Westinghouse AP1000, a 1,154-megawatt reactor with a so-called advanced passive design. It relies more heavily on forces like gravity and natural heat convection and less on pumps, valves and operator actions than other models do, in theory diminishing the probability of an accident...We need energy, and nuclear energy is one of the cleanest, best ways to provide new energy for the future. If you don't like CO2 producing power plants, you should support nuclear power.
Westinghouse says that a combination of automatic systems and design features would keep the reactor safe for three days without human intervention and that its core could be kept from melting indefinitely with only minimal operator effort.
