Instrumental neutron activation analysis with k (0) standardization (k (0)-INAA) was employed for elemental characterization of individual components of electrical cables currently used in safety systems of nuclear power plants (NPP). The analysis yielded information about the content of 35 elements. It has been found that the presently used cables would not satisfy requirements of qualification set for the new generation of NPP by "The European Utility Requirements for LWR Nuclear Power Plants", because content of several elements exceeded the maximal admissible levels. This demonstrates that cable polymer materials for safety systems of the new generation NPP must be synthesized and controlled regarding the content of additives, which are undesired from the hygienic and radiological points of view. k (0)-INAA proved to be a method of choice for elemental characterization of polymer materials of electrical cables as part of their qualification for use in NPP.
