Cost sensitivity analysis for a 100 MWe modular power plant and fusion neutron source

Abstract

The cost of electricity for a Pnet∼ 100MWe plant consisting of multiple Pfus∼70MW units is examined by developing the physics design point of a compact torus reactor with the CORSICA equilibrium/stability model and a systems analysis based on the ARIES Systems Code. Results are presented of sensitivity of cost of electricity to internal profiles, neutron wall-loading, modularity, current drive efficiency and cost of high temperature superconductors. Rolling back from the reactor, the cost and physics design point of compact fusion neutron source (Pn∼1MW Γn ∼ 1e17 m−2s−1) are also presented.
