Fig. 1.3 Light-water-moderated and -reflected core (C-core) (Ref. [1])
enriched of 650 mm length and 1.4 mm thick with an Al cladding of 0.45 mm thick;
32 plates with different curvatures and widths are used.
The fuel element is formed by assembling the fuel plates in aluminum fuel frames.
The fuel elements are loaded in a core tank of 2,000 mm diameter and 2,000 mm
depth and then immersed in light water to form the core. A part of the reflector region
can be substituted for a heavy-water reflector. Three types of fuel frames, each having
different fuel loading pitch and thus providing different neutron spectra in the core,
are available. The core can be separated into two parts with arbitrary gap width, and
it is suitable for coupled core and criticality safety studies.
The C-core is used for carrying out a wide variety of basic studies on lightwater-moderated systems, including the development of high-flux research reactor,
enrichment reduction in a research reactor, criticality safety, and study of coupled
core theory.
The C-core is also used for conducting a graduate-level joint reactor laboratory
course in affiliation with many Japanese universities in addition to conducting an
undergraduate-level reactor laboratory course in affiliation with the Kyoto University. International reactor laboratory courses for students overseas have been also
conducted since 2003.
1.1.4 Pulsed-Neutron Generator
A pulsed-neutron generator (Fig. 1.4) is attached to KUCA. Deuteron (D) ion beams
are injected onto a tritium (T) target to generate the pulsed neutrons (14 MeV
