Environmental regulator gives nod to plans for first Polish nuclear plant
Poland’s General Directorate for Environmental Protection (GDOŚ) has given its imprimatur to the Central European nation’s plan to build and operate its first nuclear power facility, state-owned utility Polskie Elektrownie Jądrowe announced last Friday.
PEJ, which submitted its environmental impact report for the proposed project to GDOŚ in March 2022, called the decision “a key permit obtained in the investment process, because subsequent administrative approvals, including the decision to determine the location of the investment and the building permit, must comply with the arrangements and conditions contained in the decision on environmental conditions.”

Nuclear fuel cycle studies have provided a wealth of information on the potential impacts of advanced recycling systems. Deciding on fuel cycle implementation pathways, however, requires synthesizing volumes of data and navigating trade-offs between fuel cycle options. This research presents a framework intended to aid fuel cycle decision makers by focusing on the cost reduction/waste mitigation trade-off as a lens for choosing a near-term strategy. The framework consists of a fuel cycle simulation coupled to a decision tree model that maps evolution scenarios. System scenarios are constructed by considering the technological options for fuel cycle evolution and key uncertainties expected to affect the desirability of those options. For this study, the once-through fuel cycle is compared to a self-sustaining fast reactor (FR) fuel cycle. Scenarios are compared using a value function that incorporates cost and waste metrics. The results indicate that uranium costs and the attainable level of reprocessing efficiency may not significantly impact the suite of desirable decisions. On the other hand, the pattern and timing of nuclear builds as well as the extent to which FRs provide true waste mitigation more significantly impact the attractiveness of closing the fuel cycle.
