Development of Site-Specific Synthetic Accelerations for Safety Assessment of DOE Facilities at Oak Ridge, Tennessee

Description: Seismic analysis of US Department of Energy (DOE) facilities at Oak Ridge, TN, requires seismic accelerograms that have response spectra that are compatible with the site-specific design response spectra. The development of these accelerograms is accomplished by the application of the Fourier transform to compute the response spectrum of a beginning accelerogram and map it into the frequency domain. The Fourier spectrum is modified according to the difference between the computed spectra and th… more

Some comments on the Shiva spaceframe earthquake damage

Description: On January 24, 1980, at 11:00 a.m., an earthquake, measuring 5.5 on the Richter scale, shook the Livermore Valley. There were three very pronounced shocks, the first at 5.5 followed by two, one at 5.2 and the other at 4.8, on the Richter scale. The Shiva spaceframe was shaken out of alignment. Shiva consists of two frames, a laser frame and a target frame. Components on each frame stayed within alignment with respect to each other, but the target frame moved with respect to the laser frame. She… more

The effects of friction on component dynamic response

Description: Friction is often used to components and piping from moving relative to building anchorages and other components. It is common analytical practice to address frictional constraints by either neglecting them and allowing unrestrained motion or by fixing them and not allowing any motion. An evaluation of the dynamic response of a component with frictional constraint is presented. Simplified component models with both fixed and fractionally constrained boundary conditions are analyzed with sinusoi… more

NRC Seismic Design Margins Program Plan

Description: Recent studies estimate that seismically induced core melt comes mainly from earthquakes in the peak ground acceleration range from 2 to 4 times the safe shutdown earthquake (SSE) acceleration used in plant design. However, from the licensing perspective of the US Nuclear Regulatory Commission, there is a continuing need for consideration of the inherent quantitative seismic margins because of, among other things, the changing perceptions of the seismic hazard. This paper discusses a Seismic De… more

Imaging earth's interior: Tomographic inversions for mantle P-wave velocity structure

Description: A formalism is developed for the tomographic inversion of seismic travel time residuals. The travel time equations are solved both simultaneously, for velocity model terms and corrections to the source locations, and progressively, for each set of terms in succession. The methods differ primarily in their treatment of source mislocation terms. Additionally, the system of equations is solved directly, neglecting source terms. The efficacy of the algorithms is explored with synthetic data as we p… more

Selection of minimum earthquake intensity in calculating pipe failure probabilities

Description: In a piping reliability analysis, it is sometimes necessary to specify a minimum ground motion intensity, usually the peak acceleration, below which the ground motions are not considered as earthquakes and, hence, are neglected. The calculated probability of failure of a piping system is dependent on this selected minimum earthquake intensity chosen for the analysis. A study was conducted to determine the effects of the minimum earthquake intensity on the probability of pipe failure. The result… more

Alternate procedures for the seismic analysis of multiply supported piping systems

Description: The seismic design of secondary systems such as piping requires knowledge of the motions at various locations of the primary structures. When the structure or buildings are subjected to earthquake-like excitations at the ground level, the responses at different floor levels may be quite different from each other. This difference depends on the building and soil frequency characteristics, the characteristics of the input signals, the damping levels, and soil-structure interaction effects. When m… more

Nonlinear seismic analysis of a large sodium pump

Description: The bearings and seismic bumpers used in a large sodium pump of a typical breeder reactor plant may need to be characterized by nonlinear springs and gaps. Then, nonlinear seismic analysis utilizing the time-history method is an effective way to predict the pump behaviors during seismic events, especially at those bearing and seismic bumper areas. In this study, synthesized time histories were developed based on specified seismic response spectra. A nonlinear seismic analysis was then conducted… more

Description: Seismic isolation is one of the most significant earthquake engineering developments in recent years. This paper describes system response analyses of base-isolated structures to earthquake ground motions. Emphasis is placed on the adaptation of a nonlinear constitutive model for the elastomeric isolation bearing together with the treatment of foundation embedment for the soil-structure- interaction analysis. The constitutive model requires six input parameters derived from bearing experimental… more

Method to generate generic floor response spectra for operating nuclear power plant

Description: The general approach in the development of the response spectra was to study the effects on the dynamic characteristics of each of the elements in the chain of events that goes between the loads and the responses. This includes the loads, the soils and the structures. A free-field earthquake response spectra was used to generate horizontal earthquake time histories. The excitation was applied through the soil and into the various structures to produce responses in equipment. An entire range of … more

Analysis of LOFT containment nozzles 11A, 11B, 11D, 12A, 13B, 13C, and 13D by Bijlaard method

Description: The purpose of this analysis was the calculation of stresses in the LOFT Containment Vessel at the point of nozzle penetration produced by loads on the nozzles and to show that those stresses are within the 1965 ASME Boiler and Pressure Vessel Code allowables. The stress determination was done by the method developed by P. P. Bijlaard on the worst load case for each diameter nozzle. The operating basis earthquake (OBE) at nozzle 11D produced the most severe load case. All load cases resulted in… more

Imaging of reservoirs and fracture systems using microearthquakes induced by hydraulic injections

Description: Predicting the future performance of a geothermal reservoir and planning a strategy for increasing productivity from the reservoir require an intimate knowledge of the fracture system through which geothermal fluids permeate. Microearthquakes often accompany hydraulic fracturing as well as normal production activities in geothermal fields. The waveforms from the se microearthquakes provide valuable information that can be used to infer the three-dimensional structure of the fracture system in t… more
