Really, dozens of fuel tank explosions in 747s. I did not know that. Do you have a list of these occurences that you would like to share?
How about if you peruse the NTSB report and look for this section:
"1.18.1 Accident Record and History of Fuel Tank Fires/Explosions on Airplanes"It will be found in amongst documents accessable from either:
the main page: NTSB TWA800 Accident Investigation
or
Factual Reports and other selected Docket Materials for Investigation DCA96MA070
