KHNP(Korea Hydro & Nuclear Power) is the largest electricity generation corporation domestically which provides approximately 32% of the national electricity demands through the hydro, nuclear, and new & renewable energy. Especially, being the one and only corporation in the nuclear power generation industry nationally, it holds a monopolistic position. Based on ‘The Act on Promotion of Restructuring of the Electric Power Industry’, KHNP spun off from KEPCO, and the number of NPP(Nuclear Power Plant) increased from 16 to 21 since the independence. Despite its enormous economical contribution by providing electricity safely at low cost, KHNP has suffered hardships in business due to the downslide of public acceptance,especially the local acceptance, on nuclear generation. Hence, the ‘partnership management with local community’ for the improvement of the local acceptance was promoted companywide since the year 2005, promoting the expansion of investment on local community, measures of symbiosis and co-prosperity with the local community, and consolidation of communication;through of which, tangible effects were obtained. The management strategy to promote a sustainable growth by actively accepting the management flow of 'CSR(Corporate Social Responsibility)' was in the background of this success. However, such strategy by KHNP has faced a new challenge since the NPP accident of Hukushima in march, 2011.
