The peak electricity draw of a house is only ever going to be the AC + Washer&Dryer + Kitchen appliances + 1.1kilowatt (for lights, TVs, devices, etc.) And this should come in at about 5-7.5Kilowatt depending on the house size.
You could contain a 5 kilowatt reactor in a room the size of a small garage, in a sub-basement floor, and due to the small size of a 5Kw reactor, the worst that will happen is the heatsoak from the nuclear pile heats up the house a few degrees.
The only problem I have is the complexity for a self-maintaining, self-regulating reactor can't possibly be built mechanically sound. There's no way any reactor could work for 25+ years without the machinery that regulates the power output breaking/needing service, and I'm talking in statistical MTBF spread over 100 million homes.
