Abstract

The OCTAVIA computer code has been developed to calculate the probability of pressure vessel failure from operationally caused pressure-transients which can occur in pressurized water reactors. The analysis approach involves calculation of vessel failure pressures using fracture mechanics methods and estimation of pressure-transient characteristics using historical nuclear data. Any of the parameters in the code can be modified for sensitivity analyses. The Surry 1 pressure vessel is analyzed as an example problem to demonstrate the code's capabilities.
