Robustness Study of Electro-Nuclear Scenario under Disruption
Abstract
:1. Introduction
2. Robustness and Relevant Assessment
2.1. Objectives and Outputs of Interest
- A. Complete substitution of the existing fleet composed of PWRs by SFRs, as preselected objective: substitution ratio is required to be between 1 and 2.
- B. Minimization of TRU in cycle (TRU includes Np, Pu, Am and Cm in this study), possibly under a limited deployment of nuclear power.
2.2. Disruption and Robustness
- Static robustness: a robust static strategy presents acceptable performance for whichever objective is selected in the future. The evolution of parameters of the trajectory is set up at the beginning of scenario. It is equivalent to an optimal static strategy that considers two objectives at once.
- Adaptive robustness: in case of the disruption, the trajectory from a strategy pursuing objective A is adapted for objective B. In this study, an adaptive strategy is considered robust (robust adaptive strategy) if it performs better than the robust static strategy for objective B.
