Reply #10: 1 Event every 500 years or 0.2%/year or 2000ppm/yr

With 440 operating reactors worldwide that would yield an incident every 13 months, on average. Looking over recent history if we assume a nominal rate of 1 major incident every 23 years. That equates to 10^-4, 1 in 10,000 operating years or 100ppm/yr.

Thats not a bad failure rate if we were talking about just a loss of the plant. But when as in these cases the loss of land use, evacuations, loss of life and/or health is this still acceptable?
