Abstract
The storage and delivery system (SDS) in fusion power plant should deliver the fuel gases, such as tritium and deuterium for the DT plasma operation. Under the environment with various fuelling scenarios and with the limitation of tritium compatible equipments it is needed to determine the process design for the fuel delivery in the SDS. The SDS has functions to satisfy the various fuelling scenarios, to minimize the tritium inventory in vapor state, and to operate safely. Based on the preliminary analysis, the configuration of pumps is selected as the three and two parallel-combined MB 601 pumps for the fuelling of T2 and D2(T) gases, respectively. The volumes of buffer vessels are determined as 0.4 m 3 and 0.3 m 3 as minimum values to satisfy the all fuelling scenarios with 120 kPa for the initial pressure for T2 and D2(T) gases, respectively. The numerical process simulations identify the new issue between the SDS and the fuelling system (FS). It needs the guideline for the lower bound of the inlet pressure in the FS to reduce the tritium inventory in long tubes between the SDS and the FS and to optimize the operability of the SDS.
