Ignitor Scale-Up Studies (DIGNITOR)

An analysis of a scaled-up version of IGNITOR (to a major radius of 2.16 m) is discussed. The design, referred to as DIGNITOR, is a direct extrapolation of IGNITOR. The consequences from the increased size are discussed (mainly due to decreased temperature excursions). A summary of comprehensive calculations of the stresses are presented. The case of a divertor plasma configuration is analyzed. The implications of a CIT-like vacuum vessel are also discussed.
