prompt: When did the construction of the twin-reactor nuclear plant begin?
  
  Cuba’s revolutionary government, headed by Fidel Castro, had long been looking for a solution in the form of nuclear energy… and that solution seemed to arrive in 1976, after talks between Cuba and the USSR resulted in an agreement to construct a twin-reactor nuclear plant near the southern town of Juragua. Funded with Soviet money, early projections suggested that the completion of the first reactor alone would have catered to over 15% of Cuba’s energy needs [1]. 
  Inside Cuba's Unfinished Nuclear Power Station
  Construction began in 1983, as the foundations were lain for the two reactors along with a sizeable turbine hall at a site close to the Caribbean. The Cubans even built a new city to house the site’s workers, “Ciudad Nuclear”, which to this day stands largely empty and unfinished (more about that soon…).
