The concept of the representative person recommended by the International Commission on Radiological Protection (ICRP) is difficult to apply to dose assessment to the public because the representative habit data could not be determined in advance for general radiation exposure situations. So, a stylized method for constructing habit data of the representative person is needed to ensure consistency and validity of the dose estimation. This paper presents a generalized model of the representative habit data based on optimization by a linear programming technique to handle complex environmental exposure situations such as radioactive waste disposal. The model is devised in such a way that it can fully embody the ICRP's criteria for the representative person by ensuring the upper 5% exposure in the population and it is applicable to general exposure systems. The model was illustrated for Korea's low-and intermediate-level radioactive waste disposal system to show its applicability to complex exposure systems with multiple scenarios and pathways.

“…Finding socially agreeable solutions for accumulating spent fuel has been commonly recognized to be crucial for sustainable utilization of nuclear power in ROK, but decision-making process for siting an interim storage facility for spent fuel has become deadlocked (Ko and Kwon, 2009). With the hope that technological options could make a breakthrough in social decision-making process, despite strong US concern for nonproliferation, in 2008, ROK changed its scheme from OTDD to a total system approach that includes pyroprocessing and sodiumcooled fast reactors (SFR) as core technologies (Long-term plan for promot and 2008 Dec. 22; Park et al, 2009).…”

Republic of Korea (ROK) changed its spent nuclear fuel policy from the once-through usage and direct disposal to a total system approach that includes pyroprocessing, sodium-cooled fast reactors, and a twotier geological repository to achieve a breakthrough for domestic deadlock situation and thus enable sustainable utilization of nuclear power, but caused disagreement in the bilateral negotiation with the United States (US) for the Nuclear Cooperation Agreement. Analysis has revealed that this shift is effective to make a breakthrough for domestic deadlock because it augments variety of technological options, with which more reversible decision-making process can be conducted to accommodate broad public needs. A trade-off has been explored first by deriving four engineering options from the ROK's system concept and then by comparing their performance from six viewpoints. The option including separation of high-heat emitting radionuclides by the electrolytic reduction process has been recommended.This option should be modified as exogenous and endogenous situations change in future. It is imperative for ROK to integrate a public-participatory decision-making process that works in concert with technology development. US can verify that ROK's motivation is not deviating from successful spent fuel management by checking if a transparent process with public participation is conducted.
