[en] Under the Korean State System of Accounting for and Control of nuclear materials (SSAC), development of the safeguards approach for the pyroprocessing, which aims to recycle the spent fuel, is required. The SSAC denotes the domestic control of nuclear materials that can be diverted to a nuclear weapons program. Safeguards, however, should be considered within the framework of Proliferation Resistance (PR), which is the ultimate goal. In this regards, we reviewed how to evaluate PR and also how to apply it to the target system. There are two major streams of research in evaluating proliferation resistance: the one is developed in the INPRO project and the other is by the GIF. In the case of Korea, with its high level of nuclear technology and complicated environmental situation, it requires a higher level of transparency. This can only be achieved by self evaluation of its facilities and research plans
