PIPING LOADS FOR A SEISMIC BOUNDARY ANCHOR AT THE CONTAINMENT PENETRATION.

Abstract

This paper describes the practice now being used in Ontario Hydro to prescribe piping loads necessary to design a seismic boundary anchor (SBA) located at a containment penetration. This procedure can be used even before any routing or analysis of the piping has been performed. Application of the procedure is illustrated via an example. Stiffness and frequency requirements for the SBA are also discussed. The approach presented here is applicable to any other location where a seismic boundary anchor is required.
