Small modular nuclear reactors less vulnerable to some accidents: vendors

Small modular reactors are less vulnerable to some types of accidents, including those like the accident at Japan's Fukushima 1 nuclear power plant that were caused by the complete loss of power, potential manufacturers of the new reactor designs told Platts Small Modular Reactors conference Monday.
NuScale Power's 45-MW modular units have no reactor coolant pumps because they rely on natural circulation for emergency cooling, chief marketing officer Bruce Landrey told the conference in Washington.
Analysis by NuScale shows it does not need an external supply of water or any power to maintain cooling, Landrey said. The NuScale units sit inside an area flooded with 4 million gallons of water that can be used for cooling, he said.
