Keywords:ITER, Divertor, Tungsten

As part of research for characterizing pure tungsten for ITER divertor with high durability to cyclic heat load, cyclic heat load test with heat flux of 20MW/m² and mechanical test were performed. Results of these tests and relation between durability to cyclic heat load and mechanical property will be presented.
