Seismic behavior of the 18-inch primary coolant pipes located in the 105-N Building
Technical Report

OSTI ID:5010428
The primary coolant system, PC(S) and PC(R), in the 105-N Building and the emergency water system are designed for a horizontal acceleration of 0.5 gravity. The rest of the NPR piping, including the primary coolant system located in the 109-N Building, is designed for 0.2 gravity. This report, however, covers only the seismic behavior of the 18-inch primary coolant pipes located in the 105-N Building. Analyses described herein confirm the design bases and adequacy of the 18-inch primary coolant pipes in the 105-N Building to resist, without serious damage, seismic forces equivalent to those produced by a local earthquake of magnitude equal to the most severe earthquake experienced on the west coast of the United States since 1906. Although the natural periods of vibration of the primary piping loops in the 105-N Building lie within the region wherein local earthquakes excite maximum dynamic effects in structural and piping systems, the design of the primary coolant piping and its support system is sufficient to keep maximum stresses in the 18-inch piping well below the maximum allowed. Lateral deflections during a severe earthquake are not expected to exceed three inches in the long horizontal runs or in the vertical runs of the individual piping loops.
