We research on contributing factors of IASCC.

1. IASCC test under irradiation by in-pile loop in JMTR. (Fig. 1)
2. Investigation of the dominant factor of IASCC (post irradiation examination)
3. Development of predictive magnetically-measured examination for IASCC
4. Impurity clustering and hardening via computational modeling
