Seismic Pipe Support Construction Practices

摘要

During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes and standards in addition to evoking new requirements. This increased scrutiny in addition to the advent of the NF subsection of the ASME code brought pipe hangers into the spotlight of nuclear plant design and construction. What before had been a minor item of low visibility became a monster causing plant delays and cost overruns. This document details some of the problems, their origins, and suggestions to reduce their impact. (ERA citation 10:023814)
