The Russian army must withdraw from the territory of the nuclear power plant and all neighboring areas, and take away its military equipment from the plant. This must happen without any conditions and as soon as possible. Ukraine is ready to ensure proper control of the IAEA, and the relevant mission can be sent to the Zaporizhia plant in a legal way, very fast and as efficiently as possible.
The reply from the “mastermind”:
Russia threatens to shut down Zaporizhzhia nuclear power plant.
The Russian Defense Ministry spokesperson claimed Ukraine is "planning a provocation" at the plant – the language Moscow often uses in its threats – that could lead to “a man-made nuclear disaster,” therefore, Moscow is “taking measures to ensure safety.” The ministry added the plant might be shut down.

So, a goodwill gesture in the face of rising condemnation [small choking noises]
or
Shut the plant down, because “the UKRies are threatening to create a disaster”, wait a bit to see how things are going in/around Kherson, then blow the plant up, or at least part of it, and declare “them UKRies did it". [No evacuation plan needed naturally].
The sabres are rattling on both sides. Chances of a DMZ? Nil.
