Description
The Water Cooled Ceramic Breeder (WCCB) blanket is one of the blanket candidates for Chinese Fusion Engineering Test Reactor (CFETR). In this work, the Primary Heat Transfer System (PHTS) of the WCCB blanket was designed based on the configuration of the blanket sectors, employing two identical loops at this stage. And each loop consists of a steam generator, a pressurizer and a main pump, feeding water coolant into 8 blanket sectors with blanket modules differing from one another. One of the loop was modeled using RELAP5/MOD3.3 with detailed blanket structures and heat sources in sectors, under normal condition and accidental scenarios. The operational mode of the PHTS was carefully chosen so as to obtain a more stable hydraulic behavior under steady state, due to the inhomogeneity of geometry structures and heat sources. Enveloping accidental cases, including in-vessel LOCA, in-box LOCA and ex-vessel LOCA, were selected to preliminarily evaluate the safety performance of the system. The results show the soundness of the system design.
