What do you think about nuclear power plants to generate electricity?

The US has continued to build nuclear power plants to generate electricity despite the fact that there does not seem to be any safe way to dispose of the expended fuel products. These expended fuel products are dangerously radioactive & just the ‘half-life’ of these expended materials is around 10,000 years. The Nuclear Regulatory Commission has tried to bury these radioactive materials, but slowly, over time, the radioactive levels leach out into the ground where they are buried & into our water tables. There does not seem to be any safe way to dispose of these radioactive materials. When you factor in earthquakes (& tsunamis) like the earthquake & tsunami that struck Japan, & led to the melt down of three of their large nuclear reactors, which has now contaminated a large portion of Japan & the ocean around the area. The melt down also put radio active particles into our atmosphere & it has traveled around our planet – contaminating all of the countries it has passed over. Many countries have decided to no longer build nuclear powered plants to generate electricity, but the US seems to be intent on continuing to build these nuclear powered plants. In your opinion, should the US be doing this, or should they be concentrating on renewable energy sources like solar, wind, wave, & geo-thermal, all of which will reduce carbon emissions from fossil fuels like oil & coal. We have to have electric power, but do you think that nuclear powered electric generating plants are the best course to follow?
