THE ANALYSIS OF STANDARD REQUIREMENTS TO THE ESTIMATION OF SEISMIC STABILITY OF PIPELINE ARMATURE WITH ELECTRIC DRIVE FOR THERMAL AND ATOMIC POWER STATIONS
The analysis of standard requirements to an estimation of firmness of pipeline armature for thermal and atomic power station is carried out, their merits and demerits are analyzed. With use of methods of theories of fluctuations and elasticity research of settlement schemes by definition of seismic stability of special armature by which results recommendations about improvement of methods of calculation are developed is carried out. Practical recommendations about carrying out of calculations of seismic stability of pipeline armature are made and operating standard approaches to an estimation of seismic stability of armature are considered and their correctness on a concrete example of regulating valve Du 400 is estimated. It is shown that in operating standard document НП-068-05 «Pipeline armature for nuclear stations. The general specifications» requirements to settlement schemes of pipeline armature are incorrect. Seismic stability calculations are spent under the licensed programs used at designing in power mechanical engineering.
