the mechanical stability of the MS. This type of destabilisation is not regulated
by industrial C&S.
The ITER Magnet Structural Design Criteria cover the metal and insulation
materials.
The SDC-IC regulatory framework is based on the general industrial RCC-
MR codes adapted to the MFR. The most important modification is related to
the neutron irradiation effects on material properties. The latest SDC-IC ver-
sion was issued in 2012. It contains the main Design Criteria and appendices.
The main document includes definitions and classifications of different dam-
ages and failures, type of stresses, design rules, and accounting for materi-
als creepage and fatigue resistivity. The rules cover single-layer homogeneous
structures exposed to low and elevated temperatures, as well as welded joints
and bolts. The appendices explain why SDC-IC are preferable compared with
other C&S, specify the computational algorithm and summarise the methods
for adjusting the in-vessel components based on experiments with full-scale
mockups.
