MECHANICAL/THERMAL PACKAGE DESIGN SAFETY ASSESSMENT AND MANUFACTURING QUALITY ASSURANCE OF SPENT FUEL TRANSPORT CASK NCS 45

ABSTRACT The NCS 45 package is designed for a variety of radioactive contents ranging from irradiated PWR, BWR and FBR fuel rods, parts of fuel rods as well as non-fissile radioactive material. BAM assessed the applicants safety analysis concept and the appropriate report with respect of requirements according to transport regulations under routine, normal and accident transport conditions related to mechanical design and thermal design, activity release and quality assurance aspects. The assesment concept of the safety report was a combination of drop test program, analytic and numerical calculations as well as various components tests. The paper will give details of BAM activities in the official safety assessment that had been summarized in the BAM design examination certificate which was a prerequisite for the Package Design Approval Certificate issued by the German competent authority
