Hope springs eternal …
… for the nuclear power faithful. Over the last couple of months, it’s become apparent that the Westinghouse AP1000, by far the most promising hope for a modern Generation III+ design, is dead in the water. Toshiba, which bought Westinghouse a while ago, is writing off billions of dollars, and seems unlikely to stay in the nuclear business after the remaining projects (all overdue and overtime) are completed. The other developed country candidates, including EPR and Candu are in an even worse state.
But wait! It seems there is a project that is on time, and possibly even on budget. It’s being built in the United Emirates by Korean company KEPCO, and consists of four plants using KEPCO’s APR-1400 design. That’s been the basis for some new optimism.
A quick look at Wikipedia’s APR-1400 article suggests this optimism may be misplaced. Among the problems
(i) This is a Gen III design, dating back to the 1990s. It hasn’t yet been certified as safe in the US, and it may not be
(ii) While the UAE project appears to have gone well, projects in South Korea have been subject to delays and cost overruns
(iii) The UAE deal was signed in 2009. There hasn’t been another export deal since then.
(iv) Although there were plans to build more plants in South Korea, they appear to have been shelved. There hasn’t been a new APR-1400 plant started there since 2013.
