Ensuring post-apocalyptic survival at TL8?

Okay, so we're completely removing inbreeding from the equation.

What would be required to more-or-less preserve TL8 or TL7 - in maintenance if not production - with a 100k pop or so? Making allowances for late-TL8 and maybe some early-TL9 stuff like Bioroids, NAIs, mature hydroponics etc.
