Description

<p>Accurate nuclear data of long-lived fission products (LLFPs) and minor actinides (MAs) are necessary to estimate the production and transmutation rates of LLFPs and MAs for the advanced reactor systems such as fast reactors and the accelerator driven systems. For the neutron capture cross section measurements, an instrument, Neutron Nucleus Reaction Instrument (NNRI) has been installed. As a major detector system, a large solid-angle Ge spectrometer is used for the prompt γ measurements with a high accuracy. Measurements on MAs and LLFPs are being performed. NNRI will be effectively used for not only MA and LLFP measurements but also generally capture cross section measurements of other elements.</p>
