This report proposes an elasto-plastic analysis method to be used for practical aseismic designing of nuclear piping system made of carbon steel. This elasto-plastic analysis method is based on the elasto-plastic analysis method which has been decided by JSME. By using this analysis method, the test result has been reproduced with sufficient accuracy for the strain range used as the intensity evaluation index of carbon steel piping. Furthermore, fatigue life has also been reproduced with sufficient accuracy...

The evaporation to dryness due to the loss of cooling functions is an event that leads to boiling and dryness if the cooling function to remove decay heat of solution is lost. We will prepare three type countermeasures against evaporation to dryness. The first measure is to prevent the evaporation to dryness. This is the countermeasure for restoring the cooling function and to stabilize the situation. The second measure is to prevent of escalation. This is the countermeasure to prevent solution from enterin...

Takahama unit No.3 is KEPCO’s first unit that has passed the safety screening against the new regulatory requirements. A new regulation “The Review for Safety Improvement on Nuclear Power Plants” was started by NRA(Nuclear Regulation Authority) and requires operators to report the results, at periodic intervals, of the review on operator’s voluntary activities for safety improvements and effects of operator’s performance. In this lecture, I will explain Takahama Unit 3’s activities. ...

Additional RPV surveillance test are required to extend the operation license of nuclear power plants. Since the number of surveillance test specimens is limited, it is important to establish a reconstitution technique of the surveillance test specimen. Applicability evaluation of reconstituted impact test specimen by electron beam welding for RPV surveillance test were conducted, and it was confirmed that reconstituted impact test specimen was applicable to RPV surveillance test. ...

Management and maintenance of electrical and I&C equipment, such as cables of nuclear power plants require a great effort. This is because there is a lot of equipment in nuclear power plants and the information which should be managed is written on a lot of documents and drawings. Therefore, the management and maintenance methods are developed. In this report, the management method od electrical and I&C equipment which is qualified environmentally is introduced....

We have developed a new diagnostic technology for rotary mechanical systems by multiplex analysis of current signals of three-phase induction motors. Since the current signal is measured from the electric panel of the electric room, the state monitoring diagnosis of the rotary mechanical system such as the dangerous area can be done easily, safely and accurately. We also built a remote and on-line monitoring and diagnostic system with current signals using IoT and cloud. This diagnostic technology and its I...

In this study, we developed a method to measure pipe wall thinning by electromagnetic acoustic resonance method (EMAR) which is one of electromagnetic ultrasonic method. The EMAR can evaluate the thickness of piping with high accuracy. In addition, we propose a method to obtain the resonance frequency with high accuracy when the thickness reduction progresses and the SN ratio decreases. We applied the technology to PWR and BWR pipings and examined its applicability....

This report is concerned with construction of an inspection robot system. The system is assumed to be composed of a set of nondestructive inspection devices and an autonomous moving robot. The inspection devices are assumed to be set over the target materials used in remote large artifacts while the robot is expected to acquire test data and to supply sufficient energies. This report is devoted to development of inspection device using electromagnetic acoustic transducer (EMAT). Guided wave inspection enabl...
