New nuclear reactors could reduce Switzerland’s winter power gap
A study by TA-Swiss says new nuclear reactors could reduce Switzerland’s reliance on electricity imports.
They could help ease the country’s winter electricity shortfall and reduce greenhouse gas emissions.
The study says this depends on reactors being ready in time, affordable and supported by suitable regulations.
Nuclear power would not replace the expansion of renewables, including solar and wind, or the need for storage and power networks.
Building new reactors would be expensive and would probably require government support.
Switzerland also faces public disagreement, possible shortages of industry expertise, licensing rules not designed for small modular reactors, and unresolved questions about used fuel.
The study sets out conditions that must be met for new nuclear technology to contribute to Switzerland’s energy supply.
