What grid? It looks like the “power box” on the wall is generating power for that house all by itself, no transmission necessary.
Considering that the smallest operating nuclear reactor ever made was this big…
…and that critical mass is a thing, I can only assume the “power box” was some kind of RTG.

The weapons grade stuff is U-235, right? Do conventional nuclear reactors enrich U-238 to U-235?

Uranium 235 or plutonium 239, may be completed with Hydrogen for more energy release: deuterium and tritium.
AFIK natural uranium is mainly centrifugated for the heavier 238 and lighter 235 to separate. Enriched uranium is just having a higher percentage of 235.
Plutonium 238 is man made in reactors
