46. International activities ■JNES and JAEA have been providing technical support to IAEA and providing assistants with Asian Nuclear Safety Network (ANSN) activities. ■A NEAT representative led a topical group on emergency preparedness and response under the frame work of ANSN. ■JNES and JAEA also organized various meetings and workshops to strengthen emergency preparedness in Asian countries.

47. Future issues ■ Functions of Emergency related organizations will continue to be tested in emergency exercises. ■We are continuing to improve the systems in emergency preparedness and response in Japan. ■The knowledge gained by the various organizations mentioned in this report can then be shared with other Asian counties. ■The IAEA plays an important roll in providing funds and opportunities. ■It is also important to further our research on such issues as RDD and consolidate our recovery phase programs.
