News of Russian forces taking control of a Ukrainian after artillery bombardment of a nuclear power plant raised concerns this week. Nuclear policy expert and Quincy Institute Distinguished Fellow Joe Cirincione joined Cheddar News to discuss the implications for a potential disaster. “I’m with the director general of the IAEA, the International Atomic Energy Agency. He says that he is extremely concerned, and that this Russian attack is a severe risk and that Russia clearly violated the fundamental principle of preserving the integrity of nuclear power plants," Cirincione said.
