Cs corrected TEM Cu precipitate dislocation loop STEM-EDS
The neutron irradiation of Fe based fusion and fission reactor materials lead to an increase in the ductile-to-brittle transition temperature (DBTT) with a decrease in the upper shelf energy. It is well known that the Cu content has a strong influence on the embrittlement phenomena; especially, the Cu-rich precipitates have been thought to be directly responsible for the embrittlement. In contrast, mechanical property studies for the steels with different Cu levels have shown that so-called matrix defects a...

Based on guidelines for volcanic effect assessment for nuclear power plant, we evaluated that the possibility of volcanic hazards affecting the safety of our nuclear power plants during the lifetime of the plant is sufficiently small by using the latest technical knowledge.
Furthermore, we are monitoring volcanic activities for the purpose of continuously confirming that the possibility of the eruption which generates volcanic hazards (pyroclastic flow etc.) unable to be addressed is sufficiently small....

Replacement Sendai Nuclear Power Station Steam Generator
In Sendai Nuclear Power Station Unit 2 of Kyushu Electric Power Co., Inc, flow-induced vibration of steam generator resulted in tube wear at support location of anti-vibration bars in the past. But steam generator integrity has been ensured thanks to established repair solutions. Integrity of steam generator can be ensured further on by continuing periodic inspection and maintenance; however for decreasing dose exposure during maintenance and ensuring long term reliability, Kyushu EPCO decided to replace st...

It is planned to implement the new inspection framework for nuclear facilities from April 2020. Since the second half of 2017, we have built a project structure in which the head office and Genkai&Sendai power station are integrated, and have been involved in operators’ conferences, collecting information, sharing information internally, and dealing with issues. We introduce our action status against key challenges including CAP, PI and free access....

JEAC JEAG new regulatory inspection subjective and continuous enhancement of safety
Principles of Nuclear Power Station's maintenance was established as Code for Maintenance at Nuclear Power Plants (JEAC 4209) in 2003 and revised in 2007,2014 And also Guide for Maintenance at Nuclear Power Plants was established in 2007 and revised in 2014. Recently these Code & Guide were revised accordingly and published as JEAC4209-2016 and as JEAG 4210-2016. Revising these Code & Guide are now under review.
Points of the revision is to implement the new regulatory inspection system enforced in 2020 ref...

The current inspection system of NRA was recommended improving and simplifying the inspection framework by Integrated Regulatory Review Service from IAEA. Therefore, NRA is preparing for the improved inspection system while referring USA’s one called ROP (Reactor Oversight Process).
About the New Inspection System, Japanese law (Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors) was amended in April 14, 2017, and it will come into force within 3 years.
Consequently, we als...
