Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. In assessing the economics of nuclear power, decommissioning and waste disposal costs are fully taken into account.
Since the 'oil shocks' of the early 1970s, energy security has been a high priority in energy policy for many countries. With uncertain fuel prices it is also a factor for utilities in making investment decisions.
Substantial amounts have been invested in energy R&D over the last 30 years, much directed at developing nuclear energy. Nowhere in the world is nuclear power subsidised per unit of production. In some countries however it is taxed because production costs are so low.
