Insurance, NRC and NIMBY's are the biggest obstacles. Lower pressure, molten-salt, smaller reactors like DMSR/MSRE @ ORNL and Taylor Wilson proposed with smaller, mass-manufactured reactors with scram/reprocessing pools beneath them would be superior to complex, one-of, inherently riskier, high-pressure *WR.
