问题    Explosions. Radiation. Evacuations. More than 30 years after Three Mile Island, the【C1】______crisis in Fukushima, Japan, has brought back some of the worst【C2】______surrounding nuclear power — and restarted a major debate about the merits and the【C3】______of this energy source. Does nuclear energy offer a path away from carbon-based fuels? Or are nuclear power plants too big a threat? It’s time to【C4】______myth from reality.
   One myth is that the biggest problem with nuclear energy is safety. Safety is certainly a critical issue,【C5】______the tragedy in Japan is making clear. But for years, the biggest challenge to sustainable nuclear energy hasn’t been safety,【C6】______cost.
   In the United States, new nuclear construction was already slowing down even before the partial meltdown at Three Mile Island in 1979. The disaster【C7】______sealed its fate. The last nuclear power plant to come online started【C8】______power in 1996 — but its construction began in 1972. Today, nuclear power remains【C9】______more expensive than coal- or gas-fired electricity,【C10】______because nuclear plants are so expensive to build.【C11】______are slippery, but a plant can cost $5 billion. A 2009 MIT study estimated that the cost of producing nuclear energy was about 30 percent higher than【C12】______of coal or gas.
   Of course, cost and safety aren’t【C13】______. Concerns about safety lead to extensive regulatory approval processes and add uncertainty to plant developers’ calculations, both of【C14】______boost the price of financing new nuclear plants. It’s not clear how much these construction costs would【C15】______if safety fears subsided and the financing became cheaper — and after the Fukushima catastrophe, we’re unlikely to find out. [br] 【C1】
