It must be in BUSHEHR! Bill Salus has been talking about this site for 30 years.

Warnings of Chernobyl-like disaster
Both global experts and Russian officials had warned of a possibly catastrophic radiological event if Bushehr, built with Russian assistance in the 1970s, was attacked by the US or Israel. They compared the aftermath of a potential strike on Bushehr to the Chernobyl disaster of April 1986. The erstwhile Soviet Union city had to be closed entirely, after fuel leaked from its nuclear facility, leading to explosions, deaths that are still not fully counted, and radiation that continues to this day. Severe environmental and geopolitical consequences would have followed if Bushehr was attacked.
The Russian hand in the Bushehr plant
The Bushehr power plant is a civilian nuclear facility, located on the Gulf Coast of Iran. Over the years, the Russians have been helping Iran build and operate Bushehr.
Amid the ongoing strikes on Iranian nuclear sites, which started with Israel bombings on June 13, and Sunday’s US bombings, both countries assured Russia that their workers would not be harmed.
Such a harm would be a diplomatic catastrophe, forcing Russia to act, and even possibly intervene, in the current war.
