Abstract
A method for simultaneously testing a plurality of fuel rod assemblies for leakage of radioactive gas, comprising the steps of removing the cover from a nuclear vessel containing the fuel rods, positioning a fixture over the fuel rods, reducing the hydrostatic pressure surrounding the fuel rods allowing gas to leak into the surrounding water, collecting water from about each fuel rod assembly in a separate chamber, separating gas from the water and testing the gas for the presence of radioactivity.
