Delivering new nuclear on time, the first time
Mark Rinehart
The nuclear industry is entering a period of renewed urgency, driven by the need for stable baseload power, heightened energy security concerns, and expanded defense infrastructure. Now more than ever, we must deliver new nuclear projects on time and on budget to maintain public trust and industry momentum.
The importance of execution certainty cannot be overstated—public trust, industry investment, and future deployment all hinge on our ability to deliver these projects successfully. However, history has shown that cost overruns and schedule delays have eroded confidence in the industry’s ability to deliver nuclear construction. As we embark on many first-of-a-kind (FOAK) reactor builds, fuel cycle infrastructure projects, and extensive defense-related nuclear projects, we must ensure that execution certainty is no longer an aspiration—it is an expectation.

In the framework of ITER magnet R&D activities, a significant number of conductor short-samples or inserts were tested throughout the past decades, either for development on cable layouts or for industrial qualifications. On a certain number of them critical properties degradations were encountered, some of which were identified to be caused by current imbalance between the different strands bundles twisted inside the cable.In order to address the analyses of those samples as reliably as possible, CEA developed a dedicated home code named Coupled Algorithm Resistive Modelling Electrical Network (CARMEN) having basically two specific functionalities:-a first routine which is devoted to compute strand bundles trajectories, with bundles down to the individual strand scale. This point allows to obtain a realistic E(J) law over the full conductor length-a second routine which is devoted to model inter-bundle currents redistribution, taking into account the magnetic field map. It basically makes use of a relevant discrete electrical network with defined sections including E(J) law obtained from the above-mentioned subroutineAs a result, the E-J or E-T curves can be calculated and compared to the experimental data, provided adapted inputs on sample features are considered, such as strand contact resistances in joints, inter-bundles resistances or cable geometry.In a first part, the paper describes the different hypotheses that built the code structure, and in a second part, the application to the ITER TFCI insert coil is presented, focusing particularly on the validation of the potential use of the code to stand as a diagnostic tool for currents imbalance probing.
