I am attaching two pics here.
One shows how I fixed heating element through ceramic beads. You can also see thermal switch.

The other one is how the ISEC looks from the top.
But I haven’t figured out the best way to seal inner pot and outer pot, ideas?

Nice pictures.
How would you insure that the neckel chrome wire will note touch the pot?

Good question.
The NiCr wire is fixed through ceramic beads, they support the wire, providing enough clearance.
