Abstract:

Background: The partitioning and transmutation (P&T) is considered as a feasible method to deal with nuclear waste. Lead-bismuth reactor is one of the most promising nuclear energy systems for Accelerator Driven System (ADS) and Generation-IV reactors. Transmutation fuel is concerned by both P&T and ADS system. Purpose: The aim is to select a suitable transmutation fuel for the lead-bismuth reactor. Methods: In this work, we analyzed characteristics of lead-bismuth reactor and ADS system, and summarized main features of transmutation fuels and design schemes of lead-bismuth reactors. Results: Most lead-bismuth reactors select nitride fuel, and features of nitride fuel are much more suitable than other fuels for the lead-bismuth system. Conclusion: Nitride fuel is currently the optimum selection of transmutation fuel in the lead-bismuth cooled reactor. Irradiation and transmutation experiments for nitride fuel in the Chinese Academy of Sciences ADS system are expected.
