Readers respond to the energy secretary’s announcement of the new £14.2bn Sizewell C power station and Rolls-Royce winning the contract to develop small modular reactors
Rolls-Royce pressurised water reactors have powered British nuclear subs since 1966, but small modular reactors (SMRs) aren’t yet proven at scale anywhere on land (Rolls-Royce named winning bidder for UK small nuclear reactors, 10 June). Only three are operating worldwide: two in Russia, one in China. Argentina is constructing the world’s fourth; is Labour simply keen to keep up with historical geopolitical rivals (Sizewell C power station to be built as part of UK’s £14bn nuclear investment, 10 June)?
The Institute for Energy Economics and Financial Analysis (IEEFA) reported actual cost overruns of 300% to 700% for all four projects. Rolls-Royce claims costs of £35 to £50 per MWh; so should we triple this? The government says the SMR project would create 3,000 new low-carbon British jobs, but at what cost? The energy secretary, Ed Miliband, can’t know the true costs yet, and three reactors doesn’t scream “economies of scale”.
