This might be of interest here. IAEA director Grossi gave a report on the known damage done to Iran’s nuclear facilities.
A few snippets…
"There has been no indication of a physical attack on the underground cascade hall containing part of the Pilot Fuel Enrichment Plant and the main Fuel Enrichment Plant. However, the loss of power to the cascade hall may have damaged the centrifuges there. The level of radioactivity outside the Natanz site has remained unchanged and at normal levels, indicating no external radiological impact to the population or the environment from this event.

I don’t know how close the IAEA inspectors could get, so I am skeptical there isn’t any damage in the underground sections of Natanz. Grossi just reported on what they know with confidence.

Grossi also said…
“Within the Natanz facility there is both radiological and chemical contamination. Considering the type of nuclear material at this facility, it is possible that uranium isotopes contained in uranium hexafluoride, uranyl fluoride and hydrogen fluoride are dispersed inside the facility. The radiation, primarily consisting of alpha particles, poses a significant danger if uranium is inhaled or ingested. However, this risk can be effectively managed with appropriate protective measures, such as using respiratory protection devices while inside the affected facilities. The main concern inside the facility is the chemical toxicity of the uranium hexafluoride and the fluoride compounds generated at the contact with water.”
He added: “At the Esfahan nuclear site, four buildings were damaged in Friday’s attack: the central chemical laboratory, a uranium conversion plant, the Tehran reactor fuel manufacturing plant, and the UF4 to EU metal processing facility, which was under construction. As in Natanz, off-site radiation levels remain unchanged.”

Finally, this is important IMO. Israel is targeting facilities thought to be associated with Iran’s weapons program. The nuclear power plant at Bushehr is only an electricity generator, and has apparently been avoided so far.
From the link…
Grossi said that Iran’s Bushehr nuclear power plant has not been targeted, and no damage had been reported at the Fordow Fuel Enrichment Plant, the Khondab heavy water reactor or the Tehran Research Reactor. “The Agency is and will remain present in Iran. Safeguards inspections in Iran will continue as soon as safety conditions allow, as is required under Iran’s NPT safeguards obligations.”

As described in the link, Iran was known to be enriching uranium up to 60% U-235. Commercial power plants use fuel enriched to around 5% or so. There is no reason, that I can see, for Iran to go to 60%, unless they are planning to get that to 90% U-235, which is the enrichment needed for weapons.
I expect the Israeli military will analyze the amount of damage inflicted, and will follow up with future air attacks, so the situation will change day-to-day.
