RESPO!TSE TO II EUTICI:T :i0, 79-07 Pipe Ftress Analysis (MCO3) is a Gilbert / Con =cnvealth proprietar/
cc=puter progrs= for the purpose of piping stress analysis.
M003 was used in the seismic analysis of safety related piping for the Three Mile Island Unit 1 nuclear project. This program dces not use algebraic su==atien of either the codirectional spatial ec=penents or inter-codal reopenses in a respense spectrum analysis. Time histor/
analfais was not used in seismic stress analysis of pipi:.J.
M003 is a pt.gran consisting of Southern Service Cc=pany's the=al stress program and I?.14's Scientific Subrcutine on eigenvalue problems.
Both the original programs and subreutines are available in the public do n'n and are veil tested.
Respenses frc= a typical M003 seismic analysis were ec= pared to PIPDEI II, a verified ec=puter program, -dth acceptable results.
