摘要：
In this paper a simple model for obtaining the pressure on the duct wall due to discharge of fission gas from a fuel pin is developed. Plenum pressure, plenum temperature, type of gas, duct effective area of cross-section and area of opening are found to be important parameters. Plenum volume, length of duct, type of liquid, and undisturbed liquid pressure were found to have less influence on peak duct pressures. The pressure-time history obtained from this analysis can be used to obtain either the permanent deformation experienced by the duct or to assess the susceptibility of the duct to fracture.
