The Chernobyl nuclear disaster has hit the news recently. April marked the 33rd anniversary of the catastrophic accident at the Soviet reactor, near the city of Pripyat, in modern day Ukraine, in 1986. In addition, a five-part historical drama starring Jared Harris, Stellan Skarsgård and Emily Watson, is also attracting plenty of viewers on Sky Atlantic.
