Abstract

Insulation systems will be a key element in the future construction and impregnation of the coils for the ITER device. Candidate materials must survive prolonged irradiation (2.5x1021 – 2.5x1022 neutrons/m2 — September 1994) simultaneous high compressive and shear stresses (up to 300 MPa and 50 MPa respectively), and have high electrical reliability (30 year service life). The materials chosen are intended to meet the demands of full scale coil manufacture. Mechanical properties, including shear / compression and compression at cryogenic temperatures of several different insulation systems are reported. The mechanically acceptable systems will be irradiation tested at a future date, although only materials believed to withstand high irradiation doses have been selected. The final results of this program are presented and compared with a pass / fail criterion based on results from a benchmark testing program (insulation system based on anhydride cured DGEBA resin and S2 glass). This work is financed by the EU under NET contract ERB 5000 940023 (NET 93–857) within the framework of ITER
