Breeder Reactors and the Energy Transition: Option or Distraction?
The energy transition is moving quickly, but not cleanly. Wind and solar are expanding, their costs have fallen, and electricity grids are being reorganised around variable generation. At the same time, transmission, storage, firm capacity, industrial demand, permitting and system coordination are becoming harder constraints. The argument is no longer only about which technologies can produce low-carbon electricity. It is about which combinations can be built, financed and operated as a dependable system. Nuclear power keeps returning to that debate because it offers firm, low-carbon generation while bringing problems of its own: high capital costs, long construction schedules, waste, political resistance and demands on public trust. In an earlier essay on the energy transition as a system problem , I argued that generation technologies should be judged by the roles they perform together rather than by a contest of preferences. Breeder reactors push the same argument into a less comf...
