This work aims to validate the calculation models and tools by comparing the calculated spectrum parameters to results obtained from a recently published study which employed Cadmium Ratio measurements at three of the irradiation channels. An analysis methodology

Nuclear and thermal analysis of a multi-reflectometer system for DEMO Fusion Eng. Des. (IF 1.692) Pub Date : 2021-02-24 Yohanes Nietiadi; Raul Luís; Antonio Silva; Emanuel Ricardo; Bruno Gonçalves; Thomas Franke; Wolfgang Biel
The reflectometry diagnostics for DEMO is envisaged to provide the radial edge density at several poloidal angles and data for the feedback control for plasma position and shape. The primary integration approach for reflectometry in DEMO involves the incorporation of several groups of antennas and waveguides into a diagnostics slim cassette (DSC), a full poloidal sector to be integrated with the water-cooled

Integration of LiPb loops for WCLL BB of European DEMO Fusion Eng. Des. (IF 1.692) Pub Date : 2021-02-24 Rocco Mozzillo; Marco Utili; Alessandro Venturini; Amelia Tincani; Curt Gliss
The eutectic alloy Lithium Lead (LiPb) enriched at 90 % in 6Li is the breeder material for one of the candidate European Breeding Blanket (BB) concepts. Currently under investigation for DEMO reactor, the Water Cooled Lithium-Lead (WCLL), and for the WCLL Test Blanket Module (TBM) that will be qualified in the ITER reactor. The LiPb alloy is used as tritium breeder, neutron multiplier and tritium carrier

Vapor adsorption testing of ambient molecular sieve bed in coolant purification system Fusion Eng. Des. (IF 1.692) Pub Date : 2021-02-24 Chang Wook Shin; Seok-Kwon Son; Eo Hwak Lee; Suk-Kwon Kim; Hyung Gon Jin; Dong Won Lee; Mu-Young Ahn; Soon Chang Park
A helium cooling system (HCS) circulates helium coolant to remove heat from a tritium breeding blanket in a fusion reactor. A small amount of tritium can permeate into the HCS from the blanket, and it should be removed as per safety requirements in the system. A coolant purification system (CPS) is connected to the HCS, and one percent of the helium flow is bypassed into the CPS from the HCS for purification
