Kikura Lab
Machine-translated · View original
A lab that improves the safety of nuclear reactors with ultrasonic and laser measurement technologies.
AboutAbout the lab
Making nuclear reactors safer through measurement and diagnostic technologies.
The Kikura Lab studies measurement and diagnostic technologies to improve the safety of nuclear reactors.
Targeting light water reactors, fast reactors, and future reactor types, the lab conducts research based on process control, measurement, and diagnostic technologies.
It also works on building a "science of recovery" aimed at the reconstruction of areas affected by the Great East Japan Earthquake and the nuclear disaster, and on developing remote measurement technologies that use robots.
Key terms
- Nondestructive testing
- Inspection that examines internal flaws and condition without damaging the object, using methods such as ultrasonic waves
- Two-phase flow
- A flow in which liquid and gas flow together in a mixture, such as water and steam
- Severe accident
- A serious accident in a nuclear reactor in which the core is damaged far beyond what the design assumed

ResearchResearch themes
To improve and advance the safety of nuclear reactors, the lab studies advanced measurement and diagnostic technologies that use ultrasonic waves, lasers, and other methods. It also works on heat and flow inside reactors, nuclear safety engineering, and numerical simulation.
*Illustrative imageMeasurement and Diagnosis Using Ultrasonics and Other Methods
The lab develops nondestructive testing and flow measurement technologies using ultrasonic waves, lasers, electrical conductivity, and image processing. It is building flowmeters that can measure the velocity profile of the flow inside a pipe while also inspecting the pipe for flaws.
*Illustrative imageNuclear Thermal Hydraulics
The lab works on high-accuracy flow measurement, research on two-phase flow, steam flow, and boiling flow, and simulation that couples electromagnetic fields with heat and flow.
*Illustrative imageNuclear Safety Engineering
The lab conducts research on severe accidents in nuclear reactors and on measuring fuel debris, the melted-down fuel and other materials.
*Illustrative imageNumerical Simulation
The lab performs ultrasonic simulation using the voxel-based finite element method, advances general-purpose simulation codes, and analyzes the behavior of nuclear power plants.
