World wide, nuclear power produces 351 gigawatts of power a year.
I was trying to calculate how many solar panels it would take to
replace this, and I assumed the solar panels were distributed, not
large solar plants. So what I really need is the amount of nuclear
power that actually makes it to the location where it will be used.
What percentage of the total power is lost in the transmission by
power lines ?
I have absolutely no idea.
http://en.wikipedia.org/wiki/Electric_power_transmission gives the
formula, but it would take quite a bit of data to figure it out, so
I'm hoping someone else has already made a ball park estimate.

Actually the wiki page does give an estimate for power loss. 7.2% in
the United States. somehow, I thought it was higher.

Typically, worldwide something like about 10% I think. Probably lower in
more developed countries.

What you are trying to calculate is difficult l as you arnt comparing
apples with apples.
Nuclear Power Plants make power 24/7, but Solar Panels only make power
for around 6 hours a day.
To replace Nuclear Plants with solar ,You have to identify where the
rest of the power will come from for the other 18 hours per day.
If you are going to use some kind of storage system, then you need to
look at the efficiency of the storage and the losses in getting the
power to and from the storage facility as well.

The OP was "Power line loss".
You may want to expand that but I was addressing the basic question.
