After major reconstruction and upgrading the 10 MW nuclear research reactor at KFKI Budapest was opened to users on 22 November 1993. Based on the research reactor, the new Budapest Neutron Centre (BNC) is intended to become a national and international centre for neutron-based research in the fields of physics, chemistry, biology and engineering. Thermal neutron fluxes averaging over 1014 n cm-2 s-1 in the core and 2×109 n cm-2 s-1 at the exterior of radial beam ports, as well as the neutron guide system and planned cold neutron source will provide unique possibilities also for nuclear physics and applications. The nuclear physics research program will focus on neutron capture physics, with special emphasis on measurements of nuclear level lifetimes using novel fast γnγγ(t) coincidence and Doppler-shift timing techniques. The (n, γ) station and the Compton suppression/pair spectrometer will alternatively be used for neutron-capture promt-gamma activation analysis (PGAA). Joint development of an ultra-fast rabbit tube system for activation analysis on very short-lived nuclides is also envisaged. For nuclear astrophysics, s-process capture cross-section measurements are planned using a filtered beam, to be constructed at one of the radial beam ports. A fundamental physics programme, such as tests of fundamental symmetries with polarized neutrons, as well as activities in nuclear solid state physics are also envisaged as soon as a polarized neutron guide becomes available.
