Considerations on the seismic qualification of electro-energetic command and control equipments for the Cernavodă Nuclear Power Plant. Protection of human habitat and major accidents prevention

Abstract

The Chernobyl events of 26 April 1986 and of Fukushima, on March 2011, reinforced the nuclear dimension of the EU energy policy by conducting a comprehensive exercise of resistance tests on nuclear installations in the European Union (and neighboring countries) during the period 2011 and subsequently with the adoption of the Council Directive 2014/87/EURATOM (2014) amending Council Directive 2009/71/ EURATOM (2009) establishing a Community framework for the safety of nuclear installations. This paper addresses some aspects specific to the Seismic Qualification Standards of the Electro-Energetic Command and Control Equipment for the Cernavoda Nuclear Power Plant, the main aspects of which include: a) Defining the seismic class of the equipment, b) Preliminary investigations, c) Seismic qualification, d) Final investigations, e) Conditions of seismic acceptance and qualification.
