    new field and analysis of seismic safety of mechanical equipment is a complex task. The complexity increases with the increased size of the mechanical system and the task becomes even more tedious if the seismic qualification is required for Nuclear Power Plant where safety requirements are very brightsideglobaltrade.com: A. K. Singh, K. G. Bhatia. John MacFarlane is a chartered mechanical and chartered civil engineer with over 30 years' experience in the heavy mechanical, civil, and nuclear industries. For the past 22 years, he has had a specific interest in the seismic qualification and design of nuclear power plant structures, systems, and plant gained in the UK and overseas.

    and other equipment systems with the rest of the structure under seismic motion are considered next. Seismic Response of Equipment and Machinery and Equipment-Structure Interactions In order to achieve effective and safe seismic design of equipment systems and also of an industrial plant, the earthquake dynamic response. “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment.” The need for a reassessment of the seismic capability of equipment in older operating plants that did not undergo the present requirements was identified as Unresolved Safety Issue A (Seismic Qualification of Equipment in Operating Plants) by the NRC in December.

This seminar presents a basis for the regulations and standards requiring Equipment Qualification of nuclear safety related components; the methods by which EQ is performed; the importance of the qualification basis to the supply of new equipment; the significance of EQ throughout plant life; and considerations applicable to the “nuclear renaissance.”.

A new approach to the seismic qualification is introduced, which highlights the need for different degrees of safety of the electrical equipment depending on the intensity of the expected ground. the seismic performance of equipment, both mechanical and electrical, could be gained by a systematic study of data collected following large earthquakes and seismic testing.

This led to several initiatives in the commercial nuclear industry to apply experience data for the seismic qualification of mechanical and electrical equipment. electrical and mechanical systems.
