Activity and decay heat calculations for the European DEMO WCLL breeder blanket module including activated LiPb flow

摘要

This paper presents the analyses performed within the SAE (Safety and Environment) project of EUROfusion/PPPT aimed at providing up-to-date estimates of the activity inventories and the decay heat generation in the WCLL. Detailed evaluation of the WCLL PPPT reactor concept based on the generic Multi-Module-Segment (MMS) model was performed by calculating the decay heat and activity inventories for the WCLL central inboard/outboard blanket modules (DEMO 2015 baseline, MMS design). Following, the estimation of radial distribution of decay heat and activity in breeder blanket module material mixture is presented. And finally, the preliminary approach to evaluate Li flow inside the breeder zone is presented in this paper. Additional calculations were performed to identify dominant nuclides after the irradiation.
