Radionuclide transport through penetrations in nuclear waste containers

; ; ;
In this paper the authors analyze radionuclide transport through penetrations in nuclear waste containers. Penetrations may result from corrosion or cracking and may be through the container material or through deposits of corrosion products. The analysis deals with the resultant radionuclide transport, but not with the way that these penetrations occur. Numerical illustrations are provided for diffusive nuclide flux through these apertures from mathematical expressions derived by Chambre. The US Nuclear Regulatory Commission's performance objective for the waste package subsystem requires substantially complete containment within the waste package from 300 to 1000 yr. Mass transfer through container holes may affect attaining substantially complete containment and may also affect compliance with the release rate requirement. Analysis of radionuclide transport through penetrations aids evaluation of individual barriers, such as Zircaloy cladding for spent fuel.
