Description
  • The paper deals with the analysis used for lifetime prolongation of nuclear power plant in Temelín. The main objective of the analysis is prediction of security of the concrete containment which is represented by post-tensioned concrete cylindrical structure which contains steel bar reinforcement in vertical, radial and horizontal directions. Three-dimensional geometry together with the use of advanced material models led to reduction in the model to the representative segment of the containment wall. High demands on computation speed and memory of the sequential version of SIFEL program led to the parallelisation of the code based on domain decomposition method. The Schur complement method was implemented for the solution of the system of linear algebraic equations. The paper also describes the system of numbering of the unknowns which had to be parallelised as a result of coupled degrees of freedom on the boundary nodes among particular subdomains.
