U.S. Nuclear Power Plants in Need of Risk Analysis

After 2011 the earthquake and resulting tsunami  that caused a triple meltdown at the Fukushima Daiichi reactors in Japan, other nations have been anxious to assess the risk of nuclear plants on their soil. In the U.S., the Nuclear Regulatory Commission announced the need for a risk re-evaluation of several nuclear power plant sites in the eastern and central regions of the country.

According to the New York Times, “Dozens of reactors at more than 20 sites across the eastern and central parts of the country need to be re-evaluated, the commission said, because of new estimates from the United States Geological Survey. The agency’s study compared the amount of ground movement predicted when the plants were designed, and the amount calculated more recently. Sites on the West Coast will be evaluated later.” The Commission has asked for a detailed risk analysis of these sites by June 2017.  That analysis will include a review of key systems that ensure the nuclear fuel stays cool should an earthquake occur, as well as a thorough analysis of the plant.

@RISK has an established reputation with experts and analysts in the nuclear power industry to assist with risk evaluation. Dr. Ching Ning Guey of Florida Power & Light has used @RISK to account for uncertainty in key aspects of the risk-informed inspection process for nuclear power plants–particularly in evaluating the probability of piping failure in these systems. Dave Whitman and Elliot Bishow of PA Consulting have harnessed @RISK's power to help clients determine the risk levels around building a new nuclear power plant, while Dr. Sola Talabi uses @RISK to develop a potential learning curve for new nuclear plant construction.

Similarly, @RISK could be used to help the Nuclear Regulatory Commission achieve their goal in assessing the threat of earthquakes and their potential effects on U.S. nuclear power plants.
