Safer nuclear fuel cladding tubes
The Fukushima disaster in 2011 triggered a demand for safer nuclear tubes.
General Electrics (GE) initiated a project in which a number of existing alloys were tested. Sandvik APMT™ material proved to be the best in test and met all relevant requirements. GE turned to Sandvik to evaluate the possibility of manufacturing thin-walled nuclear cladding tubes from this material.
The objective was to design and industrialize a production method for thin-walled APTM tubes in cladding dimensions. This had never been done before. We have now produced the tubes and tested them in a laboratory environment, which allows GE to continue their development of safe nuclear fuel tubes.
