What could have been - if nuclear power deployment had not been disrupted

If not for disruption by the anti-nuclear power protest movement the world could have had cheap, reliable, secure, sustainable comparatively safe electricity supply by now (Lang, 2017). The benefits for the global economy and human wellbeing could have been substantial: clean, safe, reliable power supply, 4.2 to 9.5 million deaths and 69 to 174 Gt CO2 emissions avoided, and nuclear providing up to 66% of the world’s power at around 10% of its current cost.
From 1954 to 1967 the cost of nuclear power plants was decreasing by around 25% per doubling of global nuclear power capacity (based on construction start dates). Then progress was disrupted. Thereafter, costs increased rapidly, by 22% to 94% per capacity doubling (except in South Korea).

If the pre-1967 rates had continued the cost of nuclear power could now be around 10% of what it is (see Table 1, and Appendix B Note XII, and V).
In 1976, about 9 years after the start of the escalating costs, the global deployment rate of construction starts stalled (red bars in figure below).

If the pre-disruption deployment rate had continued, nuclear power could have been supplying around 30% to 66% of the world’s electricity in 2015 (Figure 7). By substituting for fossil fuels, nuclear power could have avoided 4.2 to 9.5 million deaths and 69 to 174 Gt CO2 emissions between 1985 and 2015 (Table 4).
If the cost reduction rates had continued there would be no need for government interventions in markets to incentivise some, and penalise other, technologies. There would be no need for subsidies and incentives for selected technologies, and no need for renewable energy targets.
It's time for the developed countries to lead the world to get serious about nuclear power. Some of nuclear power’s advantages are, it:
- is the safest way to generate electricity and always has been since the first power reactor began supplying power to the grid in 1954 (Appendix B, Note VIII)
- is sustainable – nuclear fuel is effectively unlimited
- provides reliable, dispatchable electricity
- provides countries with a high level of energy security – many years of fuel supply can be stored in a small space at low cost so countries are not vulnerable to disruption of fuel supply during periods of trade or military conflicts
- is highly flexible in small modular reactors – consider the flexibility of nuclear powered submarines and ships, as has been demonstrated over the past 60 years; also see Irwin (2017) submission to the Australian Energy Security Board on SMR technologies.
- potential for large cost reductions over time, if the impediments to progress are removed – e.g. 25% reduction per doubling of cumulative global capacity of construction.
Other economic benefits and policy implications are presented in Sections 3.5 and 3.6.
A likely-root cause of the disruption, and the cost escalations and stalled deployment rate since about 1967 was, and still is, the activities of the anti-nuclear power protest movement (Appendix B, Note IX ).
To achieve the substantial benefits available by transitioning to nuclear power requires a recognition of the disruption and its consequences, identification of its causes, and amelioration of the impediments that are slowing progress.
