“…It is also important to note that the three high-end 25 kW ITER Cryoplants were purchased through Lump-Sum-Turnkey [LSTK] contracts for 23.5 M EUR each in 2013 [4]. Therefore, it is prudent to contact vendors for accurate and up-to-date pricing.…”

SLAC National Accelerator Laboratory has upgraded to LCLS-II, featuring a 4 GeV superconducting accelerator composed of 37 cryomodules and two large helium refrigeration systems with a total cooling capacity of 8 kW at 2.0 K. The cryogenic system at SLAC is the successful outcome of a nine-year partnership between SLAC, Fermilab, and Jefferson Lab. This paper highlights the joint efforts between Jefferson Lab and SLAC in the development and implementation of the LCLS-II Cryogenic Plants. It details the project organization, schedule, budget, staffing profile and procurement strategy.

“…According to the estimation of average heat load at 4.5 K, a helium plant with an average refrigeration capacity within the range of 75-80 kW is required for CFETR. This capacity range refers to the installed capacity of the ITER helium plant, which is 75 kW [20] to withstand an average heat load of 65 kW.…”

The China Fusion Engineering Test Reactor (CFETR) is the next tokamak in China’s roadmap for realizing commercial fusion energy. The CFETR cryogenic system is crucial to creating and maintaining operational conditions for its superconducting magnet system and thermal shields. The preliminary conceptual design of the CFETR cryogenic system has been carried out with reference to that of ITER. It will provide an average capacity of 75 to 80 kW at 4.5 K and a peak capacity of 1300 kW at 80 K. The electric power consumption of the cryogenic system is estimated to be 24 MW, and the gross building area is about 7000 m2. The relationships among the auxiliary power consumed by the cryogenic system, the fusion power gain and the recirculated power of CFETR are discussed, with the suggestion that about 52% of the electric power produced by CFETR in phase II must be recirculated to run the fusion test reactor.

“…They distribute the cooling power generated in the Cryoplant to the clients at proper conditions to sustain the Tokamak plasma experiments. The Cryoplant itself is made up of three identical liquid helium (LHe) plants, two identical 80 K gaseous helium (GHe) loops, one LHe tank and two identical liquid nitrogen (LN 2 ) plants including a huge gas management system as described elsewhere [1].…”

Abstract. Since the conceptual design of the ITER Cryodistribution many modifications have been applied due to both system optimization and improved knowledge of the clients' requirements. Process optimizations in the Cryoplant resulted in component simplifications whereas increased heat load in some of the superconducting magnet systems required more complicated process configuration but also the removal of a cold box was possible due to component arrangement standardization. Another cold box, planned for redundancy, has been removed due to the Tokamak in-Cryostat piping layout modification. In this proceeding we will summarize the present design status and component configuration of the ITER Cryodistribution with all changes implemented which aim at process optimization and simplification as well as operational reliability, stability and flexibility.
