Some key issues in the PEC fast reactor aseismic design analysis

摘要: The paper presents the main features and results of the studies carried out for the seismic verification of the Italian PEC fast reactor test facility. More precisely, after some remarks on the requirements to be satisfied by PEC in an ear thquake and a brief description of the relevant plant features, it deals with:(a) the on-site tests and calculations of the reactor building and vessel;(b) the application of the computer program CORALIE to PEC;(c) the us-e of an itera£ ive procedure for evaluating vessel-core seismic interactions;(d) the experimental tests carried out in air and water on prototype core elements;(e) the impact tests performed on core boundary ji lements;(f) the core fluid-structure interaction tests;(g) the shutdown system experimental and numerical analysis.
