Abstract

The Lithuanian energy sector is one of the most significant and problematic 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 this paper. Indicators are the parameters of the nuclear chain. A system of 22 indicators was formed in the study. The indicators were divided into four blocks: technical, economical, socio-political, and environmental. Threshold values of some indicators, employed in simulations, were obtained using an expert assessment and functional interdependences methods. In this paper the security level of the Lithuanian power supply from a nuclear energy point of view is determined. Keywords: assessment of power supply security, security indicators, nuclear sector.
