Shattered Pellet Injection (SPI) is a common technique used in Disruption Mitigation Systems to prevent or minimize the effect of plasma disruptions in Tokamaks. To operate an SPI system, a fast-acting valve is needed for accelerating pellets. An eddy current actuated high-pressure fast valve was developed in 2021, dedicated to the SPI system of the ITER DMS Support Laboratory at the Centre for Energy Research. Based on the experiences of SPI operation, a novel fast valve has been developed to improve durability and reliability, while the design has been simplified in terms of manufacturing and assembly aspects. The results of the development and laboratory testing of this novel eddy current actuated fast valve are discussed in this contribution.
