Sidney Bernsen - Nuclear Engineer, Former Chief Nuclear Engineer for Bechtel Power Corporation Nuclear Power Plants are currently too costly in the US to justify their construction as replacement for those that are being shut down, let alone to increase their contribution to clean energy. In fact we are likely to see a very significant reduction in their contribution electric energy production unless we can reduce their construction and operating costs. Many of these high costs are regulatory driven. It does appear that this effort will require the establishment of an Industry/NRC team of personnel dedicated to help make possible a realistic future for Nuclear power. The industry team should include NSSS suppliers, interested utilities and interested engineering and construction companies.

Friedrich Wagner: Germany decided to go nuclear-free by 2022. A CO2-emission-free electricity supply system based on intermittent sources, such as wind and solar - or photovoltaic (PV) - power could replace nuclear power. Intermittent sources are, by definition, unsteady. Therefore, a back-up system capable of providing power at a level of 89% of peak load would be needed. This requires creating an oversised power system to produce large amounts of surplus energy. A day storage to handle surplus is ineffective because of the day-night correlation of surplus power in the winter.

The Economist: THE Barakah nuclear-power plant under construction in Abu Dhabi will never attract the attention that the Burj Khalifa skyscraper in neighbouring Dubai does, but it is an engineering feat nonetheless. Remarkably, its first reactor may start producing energy in the first half of 2017—on schedule and (its South Korean developers insist) on budget. That would be a towering achievement. Of 55 plants under construction, the Global Nuclear Power database reckons almost two-thirds are behind schedule. The delays lift costs, and make nuclear less competitive with other sources of electricity, such as gas, coal and renewables.

Fritz Vahrenholt, PhD Chemistry: In 2012, Germany decided to close its nuclear plants, which were concentrated in the south. It reshaped the grid, building huge DC cables from north to south. The wind is more abundant in the north. A total of 6100 km of cable will have to be built by the time the last nuclear power stations shut in 2022. 400 km have been given the go-ahead and 80 km have been built, just 1.3% of the total. Due to opposition to these cables, plans have been torn up. The government now plans to build them underground, increasing the cost eight fold.
