[en] Three pillars of nuclear control regime are nuclear material accountancy control, nuclear export control and physical protection in order to assure nuclear transparency of a nation. It would be prudent to have a proper understanding of the DPRK's nuclear infrastructure before a meaningful collaboration may take place. Chapter 1 introduces the history of nuclear program development in the DPRK, Chapter 2 contains the technical framework of the state system of nuclear materials accountancy control, and Chapters 3 and 4 describe the nuclear export control and physical protection infrastructure needed in preparation for the LWR plant operation. The final Chapter 5 summarizes the salient points raised at the Muju Workshop. Completion of the Monograph series I, II, III is expected to contribute towards the successful completion of the KEDO LWR construction following the satisfactory conclusion of the IAEA verification process
