Example Embodiment

[0025] Example 1

[0026] The present invention is a method for reducing the content of the ferromagnetic structural material CLF-1 in CN HCCB TBM, and aims to reduce the ferromagnetism of CN HCCB TBM on the basis of satisfying the functional requirements of CN HCCB TBM and not making significant changes to the overall design of the existing CN HCCB TBM The use of materials reduces the waviness of the toroidal magnetic field of the ITER magnetic confinement device caused by the CNHCCB TBM.

[0027] Specific technical solutions include:

[0028] 1. The back plate of CN HCCB TBM uses non-ferromagnetic material SS 316LN-IG instead of CLF-1 as the structural material;

[0029] 2. The first wall 1, tritium multiplication zone 2, upper and lower cover 4, and partition 5 of CN HCCB TBM still use CLF-1 as the structural material;

[0030] 3. In the CN HCCB TBM first wall 1, tritium breeding zone 2, upper and lower cover 4, partition 5 and the pipe interface 6 of the rear plate 3, introduce an ...

Abstract

The invention belongs to the technical field of test blanket modules (TBMs), and particularly relates to a test blanket module for an international thermonuclear experimental reactor (ITER) with low toroidal field waviness, which can reduce the toroidal magnetic field waviness caused by a ferromagnetic material in the test blanket module. A front end structure of the test blanket module comprises a first wall, a tritium breeding region, an upper and lower cover plate and a separation rack that adopt RAFM (Reduced Activation Ferritic/Martensitic) steel as a structural material; a rear plate of the test blanket module adopts a non-ferromagnetic material 316LN as a major structural material; interfaces of the front end structure and the rear plate are connected by a middle transition layer structure; and the middle transition layer is a nickel alloy at the working condition temperature of 300-400 DEG C, and is a composite layer of the nickel alloy and the 316LN material at the working condition temperature of 400-500 DEG C. The influence of the TBM on the toroidal field waviness of the ITER is reduced greatly, the nickel alloy is adopted as the middle transition layer in a member design, so that the anisotropic material connection between the RAFM steel and the 316LN steel is realized, and the effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of the experimental cladding module (TBM) of the International Thermonuclear Experimental Reactor (ITER), and in particular relates to a low ring field ripple that can reduce the circular magnetic field ripple degree caused by the ferromagnetic material in the experimental cladding module degree of the ITER experimental cladding module. Background technique [0002] The International Thermonuclear Experimental Reactor (ITER) project is an international magnetic confinement tokamak experimental device designed to verify the feasibility of full-scale controllable nuclear fusion technology under planning and construction. The Experimental Blanket Module (TBM) is a component developed by the member countries of the ITER International Cooperation Organization to carry out physical and engineering experiments on ITER, and is used to simulate and test technologies related to the cladding of future fusion reactors. ...
