Course description and aims
The experiments will be basically performed at a nuclear facility, including Kyoto University Critical Assembly (KUCA). The students will stay at the facility, for example, for one week for the experiments. Basically the criticality experiments, the control rods calibration experiment, and the neutron flux distribution measurement experiment are performed using light water moderated core. The training for the operation of nuclear reactor and safety check of nuclear facility are also performed.
For the safe use of nuclear energy, it is necessary to understand fundamental theory of reactor physics and maintenance for safety of nuclear facility.
The radiation measurement laboratory offers an opportunity to learn technologies of radiation detectors and related equipment required for the neutron flux measurement at KUCA.
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 used for absolute measurement of radioactivity of gold wire after neutron irradiation.
Student learning outcomes
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, and neutron flux measurement.
2. Perform the fundamental safety operation of nuclear facilities
3. Perform critical calculations using group constants
4. Explain the theory of reactor kinetic calculation and activation by neutrons
5. Explain operating principles of ionizing radiation detectors based on radiation-matter interaction
6. Explain the principle of radiation spectrometry based on multichannel pulse height analyzer systems
7. Perform absolute measurement of radioactivity using scintillation gamma-ray detectors
8. Perform identification of radionuclides by gamma-ray spectroscopy using germanium semiconductor detectors

Reactor physics, Criticality approach, criticality calculation, reactor kinetics, neutron flux measurement
Radiation-matter interaction, Scintillation detector, Germanium semiconductor detector, Multichannel pulse-height analyzer, Energy spectrum
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
Pre-experiment lectures are provided before the experiments for the well understanding of the experiments. In the lectures, the outline of experimental apparatus, the principal of experiment, and the experiment procedure are explained. Students are requested to submit pre-report. The measurements and analyses are done by each student group. The group discussions about the experiment results are done after the experiments. Each student is requested to submit the experiment reports.
For radiation measurement experiments, instead of a lab report, a written exam is required.

Assessment criteria and methods
Students are assessed by the understanding of fundamentals of neutron transport theory and nuclear reactor theory.
Pre-experiment report 35%, Experiment report 35%.
Grade of radiation measurement laboratory is evaluated from the students’ understanding of the principles and practical techniques of radiation measurement, based on lab participation and a final written exam.
