Romania<\/strong><\/h2><p>Nuclearelectrica plays a major role in ensuring Romania\u2019s energy security through stable and reliable low-carbon energy production.<\/p><p>Romania\u2019s nuclear program for building a clean future includes strategic investments aimed at maintaining and increasing production capacity, thereby contributing to the energy transition and achieving Romania\u2019s decarbonization goals.<\/p><p>Through the refurbishment of Unit 1 of the Cernavod\u0103 Nuclear Power Plant, Romania is strengthening its energy security, and Nuclearelectrica will continue to ensure<strong> 20% of the national electricity <\/strong><strong>supply<\/strong>.<\/p><p>Unit 1 of the Cernavod\u0103 Nuclear Power Plant was commissioned in 1996 and marked the beginning and development of Romania\u2019s operational nuclear program. Generations of specialists in the Romanian nuclear industry, mentors of today\u2019s generations, were trained and gained experience by building and operating Unit 1.<\/p><p>From 1996 to present, the operation of Unit 1 has avoided 145 million tons of CO2 emissions and has safely delivered over 149 million MWh, with a capacity factor of over 90%. Romania ranks first internationally in terms of capacity factor since the plant\u2019s commissioning.<\/p><p>Unit 1 also served as the benchmark for Unit 2, and together they rank Romania on the first place in terms of capacity factor \u2014 a position Romania still holds today, even Unit 1 is close to the end of its first life cycle.<\/p><p>\u00a0<\/p><p><strong>Precision in action. Efficiency in managing financial and human resources. Nuclear safety as an absolute priority.<\/strong><\/p><p>The refurbishment of Unit 1 is a pillar of national energy security. Refurbishment means investment, modernized infrastructure, and a real contribution to Romania\u2019s prosperity.<\/p><p>The project is a mechanism with interconnected elements. Its effective operation requires the best expertise, enhanced focus and agile decision-making.<\/p><p>The refurbishment is a commitment by nuclear industry professionals to deliver a modern, efficient, and safe Unit 1, which will supply 10% of Romania\u2019s energy needs for another 30 years.<\/p><p>It is a promise of energy stability, of a clean and sustainable future.<\/p><p>\u00a0<\/p><p><strong>Fact Sheet<\/strong><\/p><p><strong>History &amp;
