Overview

Randomized trial quantifies environmental and economic impacts in nuclear research reactors, highlighting key areas for sustainability improvements.

Key Points

The study aims to evaluate the environmental and economic impacts of nuclear research reactors through a life cycle perspective.
Applied integrated Life Cycle Assessment and Life Cycle Costing frameworks to measure impacts.
Focused on the IEA-R1 research reactor in Brazil with one hour of full power operation as the functional unit.
Conducted sensitivity analyses to assess the impact of varying fuel inventories.
Infrastructure contributes approximately 73% of land use and 83% of water use, highlighting optimization opportunities.
Uranium enrichment leads to significant ionizing radiation and fossil resource depletion.
Economic assessment shows a negative net operational cost, aligning with the public service mission of research reactors.
