ASME FE.1:2018 pdf free download.Rules for Construction of Fusion Energy Devices.
FAA-1130 Limits of These RuLes
The rules of this Draft Standard for fusion components provide requirements for new construction and include consideration of mechanical and thermal stresses due to cyclic operation and high-temperature creep. These rules address the thermal and radiation effects on materials produced during the fusion activity. The rules do not cover deterioration that may occur in service as a result of corrosion, erosion, thermal embrittlement, or instability of material. These effects shall be taken into account with a view to realizing the design or the specified life of the components and support identified.
The rules are not intended to be applicable to valve operators, controllers, position indicators, pump Impellers, pump drivers, or other accessories and devices. unless they are pressure-retaining parts or act as support structures or supports. If such items are in a support load path, the provisions of FAA-1100 apply.
The rules of this Draft Standard do not apply to instruments, or permanently sealed fluid-filled tubing systems furnished with instruments, but they do apply to instrument, control, and sampling piping when specified hi a Design Specification.
FAA-1300 FUSION TECHNOLOGIES
Subsection FA provides the rules for construction of nuclear fusion devices and their supporting systems. Nuclear fusion and nuclear fission are two different types of energy-releasing reactions In which energy Is released from high-powered atomic bonds between the particles within a nucleus. The main difference between these two processes Is that fission Is the splitting of an atom into two or more smaller ones, whereas fusion is the fusing of two or more smaller atoms into a larger one.
Nuclear fission is a technology that has been in use since the 1950s. Figure FAA-1300-1 illustrates a typical light water fission system. There is potential for new develop. ments in nuclear energy technology to enhance nuclear energy’s role in a sustainable-energy future.
The tokamak has a confinement structure that alsoserves as a radiation-shielding barrier; the cryostatand the vv provide the vacuum boundaries. Theprimary purpose of the cryostat is to provide the environ-ment for the thermal isolation of the superconductingmagnets.The vv is located inside the magnet systemand provides the first confinement barrier for the in-vessel radiological inventory.
The thermal shield is mounted between the vv and thesuperconducting magnets on the inside, and the cryostatand the magnets on the outside.All of these componentsare mounted inside the cryostat. Inside the vV,the internalreplaceable components include blanket modules anddivertor cassettes.
FAB-1210 Magnet System
The magnet system for the ITER tokamak consists of TFcoils, a CS, PF coils,and, if necessary, CCs.The TF coilsdetermine the basic toroidal segmentation of themachine and are chosen to meet the number and size re-quirements of access ports. A typical magnet system isshown in Figure FAB-1210-1.
The TF coil case encloses the winding pack and is themain structural component of the magnet system. The TFcoil case and the winding pack are structurally linked.The CS assembly consists of a vertical stack of windingpack modules, which is supported from the bottom of theTF coils through its preload structure.The number of csmodules is designed to satisfy the plasma-shapingrequirements.
The PF coils are attached to the TF coil to allow for radialdisplacements. The PF coils provide suitable magneticfields for plasma shaping and position control.
Outside the TF coils are located, if necessary, indepen-dent sets of CCs, each consisting of coils arranged aroundthe toroidal circumference.These coils may be used tocorrect error fields (particularly toroidal asymmetry)arising from positioning errors in the TF coils, cs. andPF coils.
