  2. Fusion’s development would be accelerated by decreasing reactor unit size • Scaling present fission and ITER costs, the standard ~1000 m3 volume, 1000 MW fusion device will cost $20-30 Billion “per try”. • But…New superconducting materials may allow roughly doubling the magnetic field strength and magnet coils which can be “opened”. • 5-10 fold decrease in device volume to ~100 m3 yet maintain high energy gain. • Easier and faster access to replace smaller-size internal components. • Costs decrease to less than $5 Billion for attractive 200 MW pilot fusion plant. Small reactor “opened” up for maintenance
