I'm not going to be much help ... I live about 5 miles from the nuke plant ... maybe the Lake Wylie Chamber of Commerce could help you. You can call them at 803-831-2827. I know they use to get request for lodging in this area for people wanting to fish.

There is a company that use to handle furnished apartments ... don't know if they are still in business ... Custom Property Management 803-831-2399.
This is the local newspaper, you can look through the classifieds ...

And if all else fails ... if you have a camper or tent you can always stay at Ebenezer Park that is located on Lake Wylie.

I know, not the comforts of home and just teasing you.
Good luck, I hope you find a place to stay.
