Introduction
| |
- Application for nuclear fuel irradiation
tests in order to obtain the characteristics
(fuel temperature, internal
pressure of fuel rod, fuel deformation,
etc)
related to the study and
the development of nuclear fuel in the OR test hole
of HANARO
- Main body of the capsule is an open
basket type similar to the 18-element fuel
assembly
for HANARO
- Design and fabrication of
the capsule is similar to the instrumented capsule, consisting
of a main body, protection tube and guide tube
-
Completion of the design verification test in
HANARO's test hole (June 2003)

Design Features
|
| |
- Utilization in the studies on the irradiation
characteristic of nuclear fuel
(PWR's,
CANDU's and SMART's, etc)
- Application
in the study of the development and irradiation
characteristic of nuclear fuel for
outside users
- Length of
the capsule main body: about 1 m, diameter of
capsule main body: 56 mm,
total
length of capsule: about 5 m
- Installation
of 3∼6 test fuel rods, length of about
250∼350mm, in the capsule
- Instrumentation
consists of a thermocouple, pressure transducer and
elongation detector to
measure
the fuel temperature, internal pressure of the fuel
rod, and fuel deformation,
respectively

- Supporting irradiation tests of a nuclear
fuel pellet
- Supporting the production
of irradiation characteristics
(fuel
temperature, internal pressure of fuel rod,
fuel deformation, etc) and the design data
for nuclear fuel development
-
Supporting outside users in the study of the characteristics
of nuclear a fuel pellet
- Application of instrumentation
technology for fuel irradiation
by using 3-pin FTL,
to be utilized
from 2007
