Greece's Nuclear "Turn" (en)

1. The Geopolitical Context

Greece has decided to abandon its stance against nuclear energy, acknowledging a reality: all of its neighboring countries are already investing in it. From Kozloduy in Bulgaria and Akkuyu in Turkey, to the plants in Egypt and Romania, the wider region is becoming a nuclear hub. The Greek government now seeks to capitalize on the advantages of this technology, rather than remaining a mere observer of the risks.

2. Η Τενολογία των SMR (Small Modular Reactors)

The "spearhead" for Greece is small modular reactors. Unlike traditional large-scale plants, SMRs offer:

• Lower costs & faster construction: They are manufactured in factories and delivered ready-to-install.

• Safety: They feature advanced safety systems and are designed to withstand extreme conditions (earthquakes).

• Reliability: They operate as "base load" units 24/7, covering the gaps in renewable energy supply and meeting the needs of energy-intensive data centers.

3. Waste Challenges and Management

The main argument put forward by skeptics remains radioactive waste. However, the scientific community (as noted by Athlos Energy) emphasizes that there is now a specific international strategy involving safe underground storage in stable geological formations, a model already in use in Scandinavia.

4. Timeline and Outlook

The realization of this vision is a long-term process:

• 5–10 years: Preparation and licensing.

• 3–5 additional years:Construction and commissioning. According to experts, the key to success is initiating an honest dialogue with the public to demystify nuclear technology.

Advantages (Pros)

• Stability & Reliability: They provide 24/7 "base" power, filling in the gaps left by renewable energy sources (solar/wind) without interruption.

• Lower Construction Costs: They cost about one-third as much as traditional factories (1.5 billion vs. 5 billion) and are built more quickly in factories.

• Installation Flexibility: Due to their compact size, they can be installed near industrial zones or data centers, and new units can be added as demand grows.

• Zero CO2 Emissions: They generate clean energy, helping to achieve climate change goals and decarbonize the shipping and industrial sectors.

• Enhanced Safety: They feature passive safety systems and are designed to withstand very strong earthquakes.

• Low Operating Costs: Once constructed, energy production is cost-effective, leading to lower prices for consumers.

Disadvantages & Challenges (Against)

• Nuclear Waste: The issue of the management and long-term storage of radioactive waste remains (it must be buried at a depth of 500+ meters).

• High Initial Cost Compared to Renewable Energy/Natural Gas:  Although cheaper than large reactors, they remain a more expensive investment compared to natural gas plants or wind farms.

• Social Acceptance:There is a strong tendency to "demonize" nuclear power and widespread fear among the general public, especially in the wake of past accidents (Chernobyl, Fukushima).

• Implementation Timeframe: Despite the "speed" of SMRs, Greece will need at least 10–15 years to see the first unit in operation (due to licensing requirements).

• Technological Maturity: The technology is still in the development and implementation phase, so there are not many units in full operation worldwide from which to draw long-term usage data.
