When Russia's invasion of Ukraine first began, Russian forces seized control of the Chernobyl nuclear plant — and then took its staff hostage.

A week later the Associated Press filed this update: The United Nations' atomic watchdog says Ukraine has informed the International Atomic Energy Agency that staff who have been kept at the Chernobyl Nuclear Power Plant since Russian troops took control of the site a week ago are facing "psychological pressure and moral exhaustion." IAEA Director General Rafael Mariano Grossi said Thursday that the staff must be allowed to rest and rotate so their crucial work can be carried out safely and securely. Grossi received "a joint appeal from the Ukraine Government, regulatory authority and the national operator which added that personnel at the Chornobyl site 'have limited opportunities to communicate, move and carry out full-fledged maintenance and repair work,'" the IAEA said in a statement...

In order to reestablish legal regulation of safety of nuclear facilities and installations within the site, the IAEA was asked by the Ukrainian government to take measures.

Their article quotes the Director General of the International Atomic Energy Agency as saying that "Any accident caused as a result of the military conflict could have extremely serious consequences for people and the environment, in Ukraine and beyond."

This morning CNN shared this update: The growing exhaustion of staffers confined for "10 days" at the Chernobyl nuclear power plant is not only "difficult," but could pose "a danger to the world," Yuriy Fomichev, the mayor of Slavutych, told CNN in a telephone interview on Saturday. "People are tired; they are exhausted, both mentally and emotionally, but mainly physically," Fomichev said, adding that more than 100 people in the plant are shift personnel who should have been handed over after 12 hours. "A nuclear facility run by the same shift of 100 people without a break for 10 days in a row means their concentration levels are too low ... the main thing we want to convey is that it is very dangerous," Fomichev said.

Staffers in the plant only eat one meal per day and have limited amount of time to contact their families, Fomichev said.
