India's Department of Atomic Energy (DAE) is planning a large expansion of nuclear power, in which fast breeder reactors play an important role. Fast breeder reactors are attractive to the DAE because they produce (or "breed") more fissile material than they use. The breeder reactor is especially attractive in India, which hopes to develop a large domestic nuclear energy program even though it has primarily poor quality uranium ore that is expensive to mine.

On July 16, 2007, an earthquake with a magnitude of somewhere between 6.6 and 6.8 struck Japan. Its epicenter was about 16 kilometers north of the Kashiwazaki-Kariwa Nuclear Power Plant (KKNPP), the biggest such plant in the world. The known results of the earthquake include a fire and leaks of radioactivity. However, news of damage to the reactors continues to emerge, the most recent being the discovery of a jammed control rod in Unit-7.
