The Grohnde Nuclear Power Plant is located in Grohnde in the Hamelin-Pyrmont district in Lower Saxony. It has one reactor that uses 193 fuel assemblies and utilizes both enriched uranium and MOX fuel. In 1985, 1986, 1987, 1989, 1990 and 1998 the reactor produced more net electricity for the respective year than any other reactor in the world. The plant is of the pressurized water reactor type, using four water based coolant cycles, kept under high pressure. About 80,000 people live within 10 kilometres (6.2 mi) of the plant and a total of more than a million people within 60 kilometres (37 mi).
