The SPARC Primary Reference Discharge defined by cfsPOPCON
Abstract
The Primary Reference Discharge (PRD) is a design point maximizing the highest-achievable fusion power gain in a full-field (12.2T), full-current (8.7MA) DT-fueled H-mode on SPARC. The Primary Reference Discharge was defined in the SPARC Physics Basis using a precursor to the cfsPOPCON scoping tool. In this memo, we discuss modifications made to the cfsPOPCON scoping tool since the release of the SPARC Physics Basis and show that the key parameters of the PRD design point have not changed significantly.
