The deterministic structural integrity assessment of reactor pressure vessels under pressurized thermal shock loading
TL;DR: In this article, a 3-D finite element model is used to perform fracture mechanics analyses considering both crack initiation assessment and arrest assessment, and it is shown that the critical part along the crack front is always the clad-base metal interface point (IP) rather than the deepest point (DP) for either crack initiation or crack arrest assessment under the thermal load.

Crack initiation, arrest and tearing assessments of a RPV subjected to PTS events
TL;DR: In this paper, three types of assessment are discussed and studied: crack initiation, arrest, and tearing instability assessment in the pressurized thermal shock (PTS) events, and the results show that the tearing process of the RPV is still stable even for a big initial crack which is larger than the maximum hypothetical crack size in the code.

Long-term thermal aging performance of welding structures in primary coolant pipes for nuclear power plants
TL;DR: Welding structures of primary coolant pipes were subjected on a series of accelerated thermal aging test at 400°C until 30,000h to investigate the resulting microstructure, impact and nanoindentation properties change as discussed by the authors.
