The analysis of reactor physics experiments will be performed based on the experimental data at Kyoto University Critical Assembly (KUCA). The analysis for the criticality experiments, control rods calibration experiment and neutron flux measurement using light water moderated core will be performed.
The radiation measurement laboratory, which is held at Ookayama compus as a two-day intensive course during the summer break, offers an opportunity to learn technologies of radiation detectors and related equipment.
This class aims to deepen the understanding of them by the experiments and training.
The radiation measurement laboratory mainly aims at the understanding of operating principles and practical techniques of gamma-ray spectrometry.
By the end of the course, students will be able to:
1. Explain the principles of the experiments such as criticality approach, control rod worth measurement.
2. Perform critical calculations using group constants
3. Explain the theory of reactor kinetic calculation
4. Explain operating principles of ionizing radiation detectors based on radiation-matter interaction
5. Explain the principle of radiation spectrometry based on multichannel pulse height analyzer systems
6. Perform absolute measurement of radioactivity using scintillation gamma-ray detectors
7. Perform identification of radionuclides by gamma-ray spectroscopy using germanium semiconductor detectors
Reactor physics, Criticality approach, criticality calculation, reactor kinetics
Radiation-matter interaction, Scintillation detector, Germanium semiconductor detector, Multichannel pulse-height analyzer, Energy spectrum
✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
The lectures are provided before the analysis for the well understanding of the experiments. In the lectures, the outline of experimental apparatus, the principal of experiment, and the analysis method are explained. Students are requested to perform the analysis based on the experimental data provided and to submit the reports.
For radiation measurement experiments, instead of a lab report, a written exam is required.

To enhance effective learning, students are encouraged to spend approximately 50 minutes preparing for class and another 50 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Students are assessed by the understanding of fundamentals of neutron transport theory and nuclear reactor theory.
Analysis report: 70%.
Grade of radiation measurement laboratory is evaluated from the students’ understanding of the principles and practical techniques of radiation measurement, based on lab participation (15%) and a final written exam (15%).
It is needed to have fundamental knowledge of Nuclear Reactor Theory I and Nuclear Reactor Theory II.
For radiation measurement Laboratory, it is desirable that students have some initial background knowledge on atomic physics.
Prior appointment by e-mail is necessary.
