Description
Being part of the ITER fuelling system, the primary functions of the Gas Injection System (GIS) include providing gases for plasma discharge, wall conditioning, and neutral beam injectors. The Gas Distribution System(GDS) is a key sub-system of the GIS, which shall distribute gases obtained from the Tritium Plant, to the Gas Valve Boxes for the Pellet Injection System, Gas Fuelling System, Distruption Mitigation System and Neutral Beam system, via a distribution manifold. This paper introduces an overview of GIS and focuses on the engineering design of the GDS, especially the dedicated manifold. The main content includes:(1) Design requirements;(2) Design features;(3) Code&Standard;(4) Components classifications;(5) Boundaries and interfaces;(6) Component design;(7) On site assembly plan.
Structural analysis of GDS has been carried out by the FE method based on the load specification, whose results endorse the safety of the current GDS in given conditions. RAMI (Reliability, Availability, Maintainability&Inspect ability) analysis has been performed; meanwhile the tritium safety and accident/incident measures are considered. Besides, the manufacturing feasibility has been verified by the test compotents. All the current results introduced in this paper show the capability of GDS Manifold to achieve the expected functions and the compatibility with the latest space reservation. Final design review of GDS Manifold has been held at the domestic agency (CNDA) based on the ITER design procedure.
