Assessment of Lithuanian power supply security depending on nuclear energy

The Lithuanian energy sector is one of the most significantand problema branches of its economic sector.One of the main threats to the security of the power supply in Lithuania is the closure of the Ignalina nuclear power plant(NPP).The Lithuanian power supply is assessed in terms of security indicators in paper. Indicators are the parameters of the nuclear chain. A system of indicators was formed in the study. THe indicators were divided into four blocl technical, economical , socio-political, and environmental. Threshold values some indicators, employed in simulations, were obtained using an assessment and functional interdependences methods. In this paper the secur level of the Lithuanian power supply from a nuclear energy point ofview determinedLietuvos energetikos institutasMatematikos ir statistikos katedraVytauto Didžiojo universiteta
