[en] The maximum fluid forces acting on the LOFT DTT Rake Assembly during steady state and LOCE modes of operation, were estimated and presented for the 5-inch equivalent break flow area. A total of six loading mechanisms for each of the two modes of operation were identified. The most significant mechanisms were determined and the resulting loads and frequencies were estimated. The significant loading mechanisms were the Karman vortex-induced alternating lift forces, the steady lift forces due to pipe elbow secondary flows, and the steady drag forces
