CYCLIC TEST OF N.S. SAVANNAH REACTOR VESSEL MODEL

Tests on the quarter-scale model of the N.S. Savannah reactor vessel under cyclic loading conditions are reported, with focus on the outlet nozzle area due to previous static tests which revealed yielding there. Continuous strain data were obtained at 38 locations for 3000 cycles of the simultaneous application of the maximum design pressure of 2000 psi, together with the most severe piping reactions expected. Despite high local strain, the results of these tests confirm the structural adequacy of the outlet nozzle region. Because stresses throughout the rest of the vessel were found to be well below the yield point of the material, it is concluded that all areas of the reactor vessel are structurally adequate. Continuation of the test program is therefore not recommended. The appendices include descriptions of the test facility and procedure along with a discussion of fatigue data and a set of source data.
