Long Term Assessment of Nuclear Technology Penetration Using Message – The Case of Romania

The paper is doing a long-term simulation of the nuclear technology penetration for the Romanian power system using the IAEA MESSAGE (Model for Energy Supply Strategy Alternatives and their General Environmental Impacts) optimization model. The horizon taken into consideration is 2050 and 2070. The production and the demand are considered with various scenarios and the emissions of CO2 are also evaluated. The results are destined to assess the impact of the nuclear technology on the implementation of the EU energy and climate change policy on a long-term basis, such as to eliminate short term effects in the power system. Given the specifics of the Romanian power system both electrical energy and thermal energy (CHPs) are considered in the main scenarios.
