Joint Reactor Laboratory Course





 With the use of KUCA, a joint reactor laboratory course of graduate level is offered every summer since 1975 by 10 associated Japanese universities (Hokkaido University, Tohoku University, Tokyo Institute of Technology, Musashi Institute of Technology, Tokai University, Nagoya University, Osaka University, Kobe University of Mercantile Marine, Kyushu University and Kyoto University) in addition to a reactor laboratory course of undergraduate level for Kyoto University.
  These courses are opened for four weeks (three weeks for the joint course and one week for the undergraduate course) to students majoring in nuclear engineering and a total of 1,734 students have taken the course in the 25 years. The joint course has been institutionalized with the background that it is extremely difficult for a single university in Japan to have her own research or training reactor. By their effort the united faculty team of the joint course have succeeded in giving an effective, unique one-week course, taking advantage of their collaboration.

  The subject's offered in the reactor laboratory course are as follows:

 (1) Critical mass measurement,
 (2) Control rod calibration,
 (3) Measurement of thermal neutron flux distribution,
 (4) Educational reactor operation,
 (5) Neutron correlation experiment by the Feynman-α method,
 (6) Reactivity measurement by the pulsed neutron method.

  Usually the subjects (1)-(4) are performed in the joint course and all students participated in the KUCA experiment should attend lectures given previously in the individual university. The number of students who want participated in the joint course is usually double of adopted (a maximum number is 24 per week), because of limits such as the KUCA operation time (machine time), man-power and budget. For the undergraduate students of Kyoto University, an additional subject is offered besides the above four subjects; the measurement of xenon poisoning effect on reactivity in the Kyoto University Research Reactor (KUR), of which steady power is 5MWth. (By using the KUR, the KUCA and an election linear accelerator in KURRI, other kinds of experiments are offered for the graduated students of Kyoto University.)

  A special text book is prepared by representatives of all teachers participated in the joint reactor laboratory course, which is revised every once in 3-5 years through a representative meeting held at the end of every school year. The weekly schedule of the course and the core configuration employed in the course are also decided through discussion in the meeting.

  This joint program has the following distinctive features:

 (1) All leading universities in the field of nuclear engineering (except University of Tokyo who has a research reactor YAYOI)
   are involved in this program.
 (2) This is the first authorized course to interchange course credits between Kyoto University and other leading universities.
 (3) Course credit is 2 units.
 (4) Travel and living expenses are subsidized by the Ministry of Education, Science, Sports and Culture of Japan.
 (5) Lectures are given by distinguished professors from participating universities at the KUCA, which give strong impacts to
   students about different patterns of thinking.
 (6) It develops close personal friendships among students that continue in the future professional careers in government,
   industries, educational and research institutions.
