Methods for estimating effective hydraulic diameter of defects in leaky fuel rods based on leakage tests with pressure cycling and computer codes RTOP-CA and RTOP-LT.
Methods for estimating effective hydraulic diameter of defects in leaky fuel rods are presented. The estimation is based on pressure cycling leakage tests and the computer codes RTOP-CA, RTOP-LT This approach is used to estimate the defectiveness level of leaky fuel rods for the NPP-2006 project.
