How can the U.S. ensure new nuclear builds get off to a good start?
Bradley Williams
The United States is already off to a good start with respect to new nuclear deployment. The completion of Vogtle Units 3 and 4, the Natrium groundbreaking, and X-energy’s partnership with Dow Chemical to deploy an advanced reactor for industrial applications are all important first steps. These efforts are being complemented by the flurry of licensing activity with the Nuclear Regulatory Commission and overwhelming support in Congress and the White House. But to achieve the current administration’s goal of tripling nuclear capacity by 2050, more needs to be done.

As a continuation of the “German Risk Study: Phase A,” further plant-oriented analysis has been performed and the off-site accident consequence model has been partially improved. The plant-oriented analysis carried out at the Karlsruhe Nuclear Research Center has been focused on two release categories, namely FK2 (core meltdown followed by immediate release of radionuclides from the leaking containment) and FK6 (core meltdown followed by late release of radionuclides as a result of failure due to overpressure in the containment). The thermohydraulic processes in the molten mass and the behavior of the fission and activation products released from the molten mass are considered in a more realistic way. The improvements of the off-site accident consequence model relate mainly to a more realistic modeling of the deposition and resuspension processes, to the ingestion submodel, and to dose factors. The results show that the improvements of the off-site accident consequence model do not change the final results dramatically; the model rather draws a more realistic picture of the interrelated processes, and consequently allows the application of the model to other problems in the nuclear field as well. From the investigations belonging to the plant-oriented analysis it appears, however, that the releases to be expected from postulated accidents are remarkably lower. Consequently, the risk is lower than assessed in Phase A of this study.
