After a successful conclusion of the Cobra seal IAEA field trials, the Cobra Seal System was installed in two Canadian facilities. The seals permit on-site verification without needing to replace them in extreme weather conditions, thus allowing a substantial time reduction for inspectors as well as minimizing intrusiveness of these activities. The paper describes experiences with practical installations of almost sixty Cobra seals including the selection of environmental conduits and housing. Examples of the results of the first several inspections utilizing a new version of the Cobra seal verifier are also included. Possible future outdoor applications of Cobra seals are described and some suggested improvements are outlined.
