Aging management technical evaluation BWR Cast stainless steel Technical basis Thermal aging
Aging management technical evaluation is required for LWRs every 10 years at and after 30 years operation in Japan. Thermal aging evaluation of austenitic cast stainless steel components is one of the items of aging evaluation. Technical basis of thermal aging evaluation for BWR components such as thermal aging behavior of cast stainless steel used in Japanese BWRs, applicability of thermal aging prediction models and basic way of integrity evaluation of the components are described in this paper....

Atom probe tomography Boiling water reactor Fracture toughness Thermal aging Type 316L stainless steels Weld metals
Fracture toughness tests and atom probe tomography were conducted to evaluate the effect of thermal aging on the fracture toughness and the microstructural evolution in ferrite phase of shielded metal arc weld (SMAW) and gas tungsten arc weld (GTAW) of type 316L stainless steels. The resistance to ductile crack extension of aged welds was lower than that of unaged welds. For the GTAW the effect of aging temperature on the reduction rate of the fracture toughness, which may be due to relatively high ferrite ...

Boiling water reactor Fracture toughness Stress corrosion cracking Thermal aging Type 316L stainless steel Weld metal
Tensile test, fracture toughness test, and stress corrosion cracking (SCC) test were conducted in order to evaluate the effect of thermal aging on the mechanical properties and SCC crack growth rate of shielded metal arc weld (SMAW) and gas tungsten arc weld (GTAW) of type 316L stainless steel. Thermal aging at 350 oC induced a moderate increase of ultimate tensile strength in both the welds, and the value of GTAW was higher than that of SMAW. The resistance to ductile crack extension of aged welds was lowe...

Boiling water reactor Strain distribution Stress corrosion cracking Type 316L stainless steel X-ray stress measurement
In this study, creviced bent beam (CBB) test, x-ray stress measurement, and hardness testing on a specimen made of Type 316L stainless steel with controlled plastic strain distribution were carried out in order t o clarify behavior of crack initiation and effects of plastic strain and stress distribution on SCC initiation. The following results were obtained. (1) In this SCC test, it was found that only micro cracks whose depths were smaller than 50um were observed until 200 hours and cracks whose depths w...
