Course description and aims

The reactor physics experiments will be performed using a reactor simulator.
The radiation measurement laboratory offers an opportunity to learn technologies of radiation detectors and related equipment.

This class aims to deepen the understanding of them by the experiments.
The radiation measurement laboratory mainly aims at the understanding of operating principles and practical techniques of gamma-ray spectrometry.

Student learning outcomes

By the end of the course, students will be able to:
1. Explain the fundamental characteristics of nuclear reactors
2. Explain operating principles of ionizing radiation detectors based on radiation-matter interaction
3. Explain the principle of radiation spectrometry based on multichannel pulse height analyzer systems
4. Perform absolute measurement of radioactivity using scintillation gamma-ray detectors
5. Perform identification of radionuclides by gamma-ray spectroscopy using germanium semiconductor detectors


Reactor physics,
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

The lectures are provided before the experiments for the well understanding of it. Students are requested to perform the experiments using a simulator and to submit the reports.
For radiation measurement experiments, instead of a lab report, a written exam is required.

Out-of-Class Study Time (Preparation and Review)

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 course material.


None specified. Course materials are available at OCW-i or T2SCHOLA.

Assessment criteria and methods

Students are assessed by the understanding of fundamentals of neutron transport theory and nuclear reactor theory.
Experiment report: 50%.
Grade of radiation measurement laboratory is evaluated from the students’ understanding of the principles and practical techniques of radiation measurement, based on lab participation (25%) and a final written exam (25%).
