A nuclear reactor is based primarily on the fission of the uranium isotope ²³⁵U. We know that cleavage of 1 kg ²³⁵U releases an energy of 82 TJ (terrajoule). The Ringhals 3 nuclear reactor has a thermal power of 3144 MW and an operating time of 6000 hours / year. How long does it take to split 1 kg ²³⁵U in Ringhals 3? Answer for hours to one decimal place.
