Mr Simon Chislett-McDonald, MPhys, M.Inst.P.
My research focuses on the development, analysis and costing of new designs for net-electricity producing fusion reactors. My analysis considers the potential for more widespread use of the ductile alloy Nb-Ti in the magnet systems next-generation tokamaks. The primary goal of my research is to determine whether Nb-Ti can be used for the entire superconducting magnet system of a commercial fusion tokamak. The optimal fusion reactor design for given requirements and conditions is generated using the PROCESS systems code, developed at the Culham Centre for Fusion energy.

Topmost figure: Minimum H-factor required before the use of Nb_Ti TF coils becomes practical for a 500 MW net electrical power, aspect ratio = 3.1 (ITER-like) fusion power plant. The change in the CoE of Nb3Sn and ReBCO TF coils are shown for comparison.
Bottommost figure: Poloidal cross section of a 500 MW net electricity , A = 3.1 fusion reactor where Nb-Ti (with an improvement in the critical current density of a factor of 5) has been used for the TF and PF coils. The TF coils are of the demountable Durham/ CCFE ‘half-Phi’ design
