Course description and aims

Students learn the basic knowledge and techniques of nuclear engineering through experiment and experience in the following two themes:
(1) Thermal-hydraulics: Reactor core cooling phenomena such as single-phase heat transfer, boiling two-phase flow regime and critical heat flux (CHF)
(2) Radiation measurement: Measuring techniques of alpha/beta/gamma-rays from radioisotopes and radiation-matter interactions.

Student learning outcomes

By the end of this course, students will be able to:
(1) Understand the coolant behaviors in increase of core fuel temperature, and discuss and do experimental study on safe reactor cooling.
(2) Understand the interaction between radiation and matter, and explain basic methodologies of radiation measurement.


Heat transfer, Boiling, Two-phase flow, Critical heat flux (CHF), Burnout, Alpha-ray, beta-ray, gamma-ray, semiconductor detector, GM counter, stopping power, range, energy spectrum, Poisson distribution

Competencies that will be developed

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

Class flow

Class 1 and class 2 give lectures for all the students. These lectures are followed by lab classes, in which the students are divided into groups for different lab works. The students conduct the lab works under the guidance of instructors.
