Modification of DOHEAT for optimization of coolant conditions in DEMO blanket

Uto, Hiroyasu; Tobita, Kenji; Someya, Yoji; Nakamura, Makoto

For optimization of coolant conditions in DEMO blanket design, a two-dimensional (2-D) nuclear-thermal-coupled analysis code, DOHEAT, has been modified. The striking feature of DOHEAT is to have a user-friendly interface that enables users to create an appropriate analysis model for different blanket concepts without much difficulty. However, in the previous version of DOHEAT, the coolant temperature is given as an input data. Actually, a temperature change of the coolant along the cooling tube needs to be determined implicitly when the inlet temperature, pressure and flow speed are given. In modified DOHEAT, the coolant condition calculation module was added into the 2-D thermal analysis module, and the temperature profile in the blanket was provided based on the nuclear heating rate profile and coolant temperature. A validation calculation indicates that DOHEAT provides reasonable results on the temperature profile in the blanket.
