Atlanta: If disaster strikes a nuclear power plant in the US, the utility industry wants the ability to fly in heavy-duty equipment that could avert a meltdown.
That capability is part of a larger industry plan being developed to meet new rules that emerged since a 2011 tsunami struck the Fukushima Dai-ichi nuclear plant in Japan, flooding its emergency equipment and causing nuclear meltdowns that sent radiation leaking into the environment.
The tsunami exceeded the worst-case scenario the plant was designed to withstand, and it showed how a widespread disaster that damages a nuclear plant can complicate emergency plans.
The effort, called FLEX, is the nuclear industry`s method for meeting new US Nuclear Regulatory Commission rules that will force 65 plants in the US to get extra emergency equipment on site and store it protectively.
As a backup, the industry is developing regional hubs in Memphis, Tennessee, and Phoenix , Arizona, that could truck or even fly in more equipment to stricken reactors.
Industry leaders say the effort will add another layer of defense in case a Fukushima-style disaster destroys a nuclear plant`s multiple backup systems.
"It became very clear in Japan that utilities became quickly overwhelmed," said Joe Pollock, vice president for nuclear operations at the Nuclear Energy Institute, an industry lobbying group that is spearheading the effort.
Nuclear industry watchdogs are concerned that by moving first, the utility industry is attempting to head-off more costly and far-reaching requirements that might otherwise be set by the NRC, which oversees commercial nuclear power plants in the US Plants started buying the new equipment even before NRC regulators approved the concept. Industry officials say they are not certain yet how the equipment would be moved in a crisis.
"That presented essentially facts-on-the-ground for the NRC and essentially gave the industry the upper hand in how this is going to play out," said Edwin Lyman, the senior scientist for the Union of Concerned Scientists, who criticized FLEX as a "window-dressing exercise."
U.S. Nuclear plants already have backup safety systems and are supposed to withstand the worst possible disasters in their regions, including hurricanes, tornadoes, floods and earthquakes. But planners can be wrong.
The Japanese utility TEPCO dismissed scientific evidence and geological history showing that the Fukushima Dai-ichi plant was susceptible to being struck by a far bigger tsunami than it said was possible.
Dominion Virginia Power`s North Anna Power Station was struck by a 2011 tremor that caused peak ground movement at about twice the level for which the plant was designed. It did not suffer major damage and has resumed operations.
