@ Whatever the era, half of all dams that ever fail, do so in the first five years. This high infant mortality is often due to piping in the soil around the dam or underneath it. Even concrete dams are not immune. However, dam construction dropped dramatically after 1980 so that nearly all dams are older than 5 years.lnalnf rma n U.S.NRC N R R -0Nmo STATESNIRUAR REGLI ATORC Protecting People and the Environment Technical Lessons Learned Investigation of Dam Failure Frequencies http://crunch.tec~army.mil/nid/webpaqes/nid.cfm http://npdp.stanfordedu/index.html All Arch Dams All Buttress Dams All Concrete Dams All Earth Dams All Gravity Dams All Masonry Dams All Multi-Arch Dams All Rockfill Dams All Stone Dams All Timber Crib Dams Total Buttress Dams Over 50 Feet Arch Dams Over 50 Feet Concrete Dams Over 50 Feet Earth Dams Over 50 Feet Gravity Dams Over 50 Feet Masonry Dams Over 50 Feet Multi-Arch Dams Over 50 Feet Rockfill Dams Over 50 feet Total Failures 2 2 10 366 28 5 0 7 2 3 425 Failures 0 2 0 56 7 0 0 4 69 Dam.years 9101 9819 110227 2240403 122798 21692 240 55872 11365 6536 2605987 Dam-years 1876 5667 19215 144810 19542 1987 77 19900 213184 Mean 2.1E-04 1.9E-04 9.3E-05 1.6E-04 2.3E-04 2.2E-04 1.5E-04 1.3E-04 1.7E-04 3.6E-04 1.6E-04 Mean 2,OE-04 2.8E-04 8.2E-05 3.8E-04 3.2E-04 2.OE-04 2.4E-04 2.1E-04 2.4E-04 NRR Lhi 'alUseO90

-Ft Calhoun and Diablo Canyon. Everyone else only addressed probable maximum precipitation and screened out dam failure as low probability.
s Unfortunately, there were few dam failure data sources around back then, so many plants used the estimate published in NUREG/CR-5042.
The data source for the estimate in NUREG/CR-5042 was the Oconee PRA -NSAC/60. The estimate of 2.5E-05/dam-year in NSAC/60 was done in error by an order of magnitude and it propagated throughout the industry.e

It is noteworthy that all forms of dams have a failure rate between 1 E-4 and 4E-4, even for blue sky events.Determining flood levels, however, is a complex matter. The USACOE has software named HEC RAS that when combined with GIS geographical data will model river flow and flooding in great detail.Weather based floods remain in the deterministic world because the input conditions are always from the same source as was used in the original plant design basis. Besides, the growth of the maximum precipitation only increases about 20% when a 100 year interval is compared to a 1000 year interval.
With only 100 years of data available in many locations, projecting beyond a I E-3/yr event is very uncertain anyway.N R R 0n nlfom o IN S1TAtSNUIA RE .TR£OMS HIC-8 liýProteding~People and th'e nviunmati Process Lessons Learned@ Process did not account for situations where licensee did not communicate to the regional office and waived participation in a regulatory conference.
