Today, it has six power reactors with a combined capacity of 4.9 gigawatts of electricity. For its part, South Korea has 11 reactors on line with a combined capacity of about 9 gigawatts of electricity. Specifically, we have calculated from the size of reactors and time when each came on line in each country that Taiwan today has about 45,000 cubic meters of low level waste, whereas South Korea has about 50,000. This looks dramatic until put into perspective. Volume doesn't matter much when it comes to nuclear waste.
Radioactive materials do.
Each year, a gigawatt sized reactor generates about 600 million curies of radioactive isotopes a year in the form of high level waste of a small volume. The real issue in both North and South Korea is not low level waste, but high level waste in spent fuel ponds and in reactor cores. In North Korea, the spent fuel from its small research reactor is being canned by combined teams of American and North Korean technicians, and eventually will be shipped out of North Korea. North Korea is not producing more radioactive waste today and will not produce more until KEDO completes the promised two light water reactors. At this time, North Korea has no more idea about what it will do with its high level nuclear wastes at that time than does the South, Japan, or any other state operating nuclear power plants.
