The Budapest Neutron Centre is the Hungarian centre for reactor based neutron research in the field of physics, chemistry, materials science and engineering.

In 1997, three academic research institutes formed a consortium under the name of Budapest Neutron Centre (BNC) to co-ordinate research activities associated with the Budapest Research Reactor (BRR). The three founders are: KFKI Atomic Energy Research Institute, the Research Institute for Solid State Physics and Optics, and the Institute of Isotopes. In 2005, KFKI Research Institute for Particle and Nuclear Physics joint in BNC. Budapest Neutron Centre is represented by the KFKI Atomic Energy Research Institute.

The BRR is the largest neutron research facility in Central Europe. The 10 MW reactor power provides with a maximum thermal neutron flux of 2.2x1014 n/cm2s and with a fast neutron flux of 1x1014 n/cm2s. The reactor has 10 horizontal beam tubes (eight radial and two tangential). At one of the tangential beam tubes a cold neutron source (CNS) has been installed. Three neutron guides originate from the point where the CNS is installed providing neutron measurement site in the guide hall adjacent to the reactor hall. The neutron guides can be used either with thermal or cold neutron spectra.

The BRR is mainly used for neutron research; this research possibility was offered to the European Scientists in the 5th Framework Programme of the European Commission. BNC intends to continue the successful Access Programme under the NMI3 project of FP6.
