 Following the Japanese Fukushima Daiichi nuclear disaster, according to Black & Veatch’s annual utility survey that took place after the disaster, of the 700 executives from the US electric utility industry that were surveyed, nuclear safety was the top concern.There are likely to be increased requirements for on-site spent fuel management and elevated design basis threats at nuclear power plants.License extensions for existing reactors will face additional scrutiny, with outcomes depending on the degree to which plants can meet new requirements, and some extensions already granted for more than 60 of the 104 operating U.S. reactors could be revisited.
