Decision-making of nuclear energy policy: application of environ- mental management tool to nuclear fuel cycle

摘要

This study aims to evaluate and estimate the environmental impacts of nuclear fuel cycles and to support the decision-making of nuclear energy policy, relating to a selection of environmentally preferred nuclear fuel cycle for the environmentally sound and sustainable development of nuclear energy. To achieve this objective, life cycle assessment(LCA)as an environmental management tool is applied to the nuclear fuel cycle alternatives of a once-through fuel cycle, the direct use of PWR spent fuel in CANDU (DUPIC)cycle and recycling with plutonium and uranium recovery by extraction(PUREX)process.
