Use of renewable sources like solar and wind is rapidly increasing, while nuclear, though long a reliable source of carbon-free electricity, is not. Meanwhile, a number of startups are promising cheap, safe, proliferation-resistant nuclear energy in the next decade (see “Fail-Safe Nuclear Power”).
Can these startups fulfill their promises? Outside of China, nuclear power is expanding nowhere. China has 21 new reactors under construction; Russia has nine, India six. The U.S. is bringing five new plants online, but since 2012, five other reactors have been retired, with seven more to be shuttered by 2019. California’s Diablo Canyon plant recently announced it will close by 2025. With other plants closing in Japan, Germany, and the U.K., more reactors may be decommissioned than built in the near future. Link to Original Source
Since uranium runs out, the subsidies for nuclear never tend to zero the way the do for solar which can produce energy without bound long after subsidies end. With the nuclear waste problem, subsidies for nuclear likely increase without bound. You've misunderstood the situation.

The early federal statements gave no hint that the blast had caused massive long-term damage to the dump, a facility crucial to the nuclear weapons cleanup program that spans the nation, or that it would jeopardize the Energy Department’s credibility in dealing with the tricky problem of radioactive waste.
But the explosion ranks among the costliest nuclear accidents in U.S. history, according to a Times analysis. The long-term cost of the mishap could top $2 billion, an amount roughly in the range of the cleanup after the 1979 partial meltdown at the Three Mile Island nuclear power plant in Pennsylvania.
The Feb. 14, 2014, accident is also complicating cleanup programs at about a dozen current and former nuclear weapons sites across the U.S. Thousands of tons of radioactive waste that were headed for the dump are backed up in Idaho, Washington, New Mexico and elsewhere, state officials said in interviews.

A new study of European countries, published in the journal Climate Policy, shows that the most progress towards reducing carbon emissions and increasing renewable energy sources – as set out in the EU’s 2020 Strategy – has been made by nations without nuclear energy or with plans to reduce it.
Conversely, pro-nuclear countries have been slower to implement wind, solar and hydropower technologies and to tackle emissions.
While it’s difficult to show a causal link, the researchers say the study casts significant doubts on nuclear energy as the answer to combating climate change.
“By suppressing better ways to meet climate goals, evidence suggests entrenched commitments to nuclear power may actually be counterproductive.” Link to Original Source
