Abstract

The multipurpose VHTR being developed by JAERI will use TRISO-coated low enriched UO2> particles in the form of hollow cylinder called fuel compact. The dimension of the particle and the compact are shown in Table 1. Compacts are encased in a graphite sleeve to complete a fuel rod. Design target conditions for the fuel are 1350 deg. C, 2% FIMA and 7x1020 n/cm2 (E > 0.18MeV). Irradiation tests of the fuel have been performed in JMTR using a gas loop, sweep-gas capsules and closed capsules. The purpose of the present paper is to review the current status of these irradiation tests
