� Aspects of mechanical safety assessment of RAM packages
� Competent authority in Germany is BAM Federal Institute for Materials Research and Testing
� TÜV experts are authorized from BAM for subtasks
� Demonstration of compliance with national and international transport
regulations required for each package design
� European PDSR-Guide assists in preparation of Package Design Safety Report
� BAM guidelines * regulate parts of mechanical design calculations
� BAM-GGR 011: Definition of safety objectives ** and classification ofcomponents
Overview
*) E.g. GGR 008: Numerical safety analysis; GGR 012: Lid systems and load attachment points**) Shielding, containment, integrity, prevention of criticality
PATRAM 2013 4Olaf Schilling
Component Classification according BAM GGR 011and Analysis Approaches
� Other influences on design calculation effort:• Safety margin • Geometrical and structural (material properties) complexity
Componentclassification
examples Usual analysis approaches
Grade 3(low safety relevance)
Type plate, O-rings Sometimes analysis not necessary
