Helium-cooled ceramic beryllium blankets The blanket concept described here was origin￾ally proposed for the DREAM reactor [13] and thereafter it was applied for A-SSTR2 [14] with only little modifications. 4.1. Blanket description The power core torus structure is radially divided into equal sectors and each sector forms an assembling unit. Each sector has its own horizontal maintenance port, allowing replace￾ment of the entire sector without opening the cryostat or disassembling other components such as the coil system. One blanket sector is divided into 16 sub-sectors (rings) in the toroidal direction. Fig. 4. TAURO blanket design, breakdown in elementary components. 314 L.
