Scope

This standard provides an analytical method for calculating the release of volatile fission products from uranium dioxide fuel pellets during normal reactor operation. When used with nuclide yields, this method will give the release-to-birth ratio, R/B, or the so-called gap release, which is the inventory of volatile radioactive fission products that could be available for release from the fuel rod if the cladding were breached.
