One-fifth-scale dowel force test report. [HTGR]
The report presents the results of the second seismic test program conducted on the 1/5-scale, full-array model of the 3000 MW(t) high-temperature gas-cooled reactor (HTGR) core. The test conditions consisted of uniaxial horizontal sine sweeps at 0.5 g fixture acceleration, sine dwells at various g-levels and frequencies, and time history excitations at several g-levels conforming to NRC seismic response spectra for seismic category 1 components. The main objective of the program was to measure fuel element and reflector block dowel forces. In addition, measurements were taken for core damping, fuel element collision, and fuel element and reflector block rocking angles. These data were required to provide a broader base for validating analytical computer models used to calculate HTGR core design loads.
