Shadow treasurer Angus Taylor says the Coalition expects to make an economic return on its plan to kick-start a domestic nuclear power industry, after new data revealed that the custodians of more than $4 trillion in Australian retirement savings have almost no appetite for investing in the technology.

Only 14 per cent of 65 large superannuation fund managers and asset owners surveyed by a major climate-focused investment organisation are planning to gain exposure to nuclear in the near future, compared with 63 per cent who showed interest in making renewable energy investments.
