ABSTRACT
The use of low enriched
uranium (LEU) fuel target was examined on the feasibility of 99Mo
production in a research reactor, HANARO. Uncertainty analysis was done with
respect to 99Mo yield ratio, 239Pu yield ratio, annual
production rate, and decontamination requirement. An equilibrium core model for
MCNP fixed-source problem
was found by reactor design methodology, WIMS/VENTURE. Target design option
with LEU was proposed. Variables related to target fabrication process and
reactor physics condition was considered as uncertainty-inducing parameters.
The most important factor affecting the overall uncertainty in LEU option was engineering
tolerance in fabrication process of fuel film. It is acceptable to use LEU as a
target fuel in view of radioactive purity of alpha emitter because the
uncertainty in impurity level of 239Pu is expected to be relatively
small, only 6% in 95% confidence level.
