Course description and aims

To assist the education of laboratory experiment related to basic nuclear engineering for graduate students. The experiment consists of nuclear reactor physics, radiation measurement, and nuclear security laboratory. To assist the preparation, improvement and enforcement of the experimental education including lectures.

Student learning outcomes

Students have the ability of assisting the following experimental education for graduate students:
(1) Nuclear-reactor physics: Principle and methods in reactor physics experiments using nuclear reactor
(2) Radiation‐measurement: Operating principles of ionizing radiation detectors and gamma-ray spectrometry
(3) Nuclear security laboratory: Operating principles of uranium enrichment measurement by gamma-ray spectrometry and its application for nuclear security and safeguards


Reactor physics, Criticality approach, criticality calculation, reactor kinetics, Radiation-matter interaction, Scintillation detector, Germanium semiconductor detector, Multichannel pulse-height analyzer, Energy spectrum, Uranium enrichment measurement, Nuclear security, Nuclear safeguards

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Gamma-ray measurement using a germanium semiconductor detector 7. Uranium enrichment measurement using gamma-ray measurement 1. Students must be able to explain about the fundamental theory in critical approach experiment and perform criticality calculation, be able to estimate criticality mass by the inverse multiplication in criticality approach experiment, and be able to judge of criticality of nuclear reactor. 2. Student must be able to calculate control rod worth from the result of experiments by period method and compensation method. 3. Student must be able to calculate control rod worth from the result of experiments by rod drop method. 4. Student must be able to explain about the fundamentals of nuclear reactor operation 5. Students must be able to perform absolute measurement of radioactivity using scintillation gamma-ray detectors 6. Students must be able to perform identification of radionuclides by gamma-ray spectroscopy using germanium semiconductor detectors 7. Students must be able to perform nondestructive assay of uranium enrichment important in nuclear security and safeguards

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 textbooks and other course material.
