Engineered Solutions
As a result of the 2011 Fukushima Daiichi accident, the NRC mandated that all nuclear power plants in the U.S. add an additional level of protection from a complete loss of power to decay heat removal systems via a temporary power system called “FLEX”. CBS Nuclear Services designed custom devices for many of our nation’s nuclear plants to be used in place of existing circuit breakers that allow for quick connection to the FLEX system’s universal generator cables.
