摘要

Criteria of the safety assessment procedure are described with regard to pipelines of the FBR secondary loop. The short-term and long-term properties of strength and ductility, fracture toughness, creep rate, and creep crack growth rate within the temperature range of 550-800℃ for steel 08Cr16Ni11Mo3 are given. The most probable scenario of sodium combustion is proposed. Results of the testing procedures in a straight section of the pipeline DN 900 with the sodium leakage via through cracks and its combustion on the external surface are presented. A diagram of the admissible states of the pipeline concerning the discharge of sodium is constructed.
