Kiev - The last remaining reactor at Ukraine's Chernobyl nuclear power plant shut down automatically on Sunday after the safety system detected a malfunction in a transformer, a plant official said yesterday, adding that no radiation was released.
The third reactor is the last of four original reactors still operating after reactor Number 4 exploded in April, 1986, spewing a poisonous radioactive cloud over Europe and contaminating large areas of Ukraine, Belarus and Russia.
