Russia is set to air a TV series based on the Chernobyl nuclear disaster that implicates the United States as playing a role in the worst nuclear accident in history.

Currently in post-production, the series by the Russian company NTV tells the story of the 1986 explosion that ripped through reactor Number 4 at the Chernobyl Nuclear Power Plant in the then Ukrainian Soviet Socialist Republic.

The explosion led to a huge radioactive leak, which permanently affected areas in places across three quarters of Europe. Thirty workers and firemen were killed in the immediate aftermath of the explosion and rescue operations. Most of them died of severe radiation-related illnesses.

The plot revolves around a CIA agent dispatched to Pripyat — the town inhabited by Chernobyl workers — to gather intelligence on the nuclear power plant.

The series will follow KGB officers in their attempts to hunt the espionage operation.

Director Aleksey Muradov said that his version, filmed in Belarus, will show "what really happened back then.”

“There is a theory that the Americans had infiltrated the Chernobyl nuclear power plant,” he said. “Many historians do not deny that on the day of the explosion an agent of the enemy’s intelligence services was present at the station.

This is while a five-part "Chernobyl" series produced by American premium cable and satellite television network HBO has recently triggered worldwide debate as some experts have challenged its credibility.

Russia’s most popular newspaper, Komsomolskaya Pravda (KP), has dismissed the show as “a caricature and not the truth.”

“If Anglo-Saxons film something about Russians, it definitely will not correspond to the truth,” said Russian journalist Anatoly Vasserman.

Russian newspaper The Moscow Times, also wrote this week that the HBO production was biased against the Soviet Union and provided a "caricature"’ of the nation.
