(Yahoo) Ukraine says Russia plans to simulate accident at nuclear power plant. Quoting,

(Reuters) – Ukraine’s defence ministry on Friday said Russia was planning to simulate a major accident at a nuclear power station controlled by pro-Moscow forces to try to thwart a long-planned Ukrainian counteroffensive to retake territory occupied by Russia.

This is anticipated in (2/19/2023) Russia to use Dirty Bombs in Ukraine?  Quoting,

Prior Russian assertions have not been followed by Russian use of radiological weapons. This results in opinion of the current assertion as propaganda without material consequence. This may be a grave error. We watched with concern when Russians occupied the Zaporizhzhia reactor hall, anticipating they might stage a containment breach.

“Simulate” may indicate a controlled release, rather than a  containment breach, which would inevitably contaminate Russian land.
