Barriers Preventing the Release of Fission Products

As can be seen from the schematic diagram in Fig. 1.11., four independent, passive barriers prevent the release of fission products from the fuel to the environment in the case of accident ... [Pg.28]

The fuel cladding is the second barrier, and (from the viewpoint of normal operation) the most significant barrier preventing the release of fission products into the reactor coolant. Regular and proper leak testing of fuel assemblies is an inevitable requirement that is closely related to not only operational regulations but also attempts to assure optimal operation from a radiation protection point of view.
