Abstract
A part of the Institute in Vinca this monograph refers to is the thermal nuclear zero power reactor RB, with a heavy water moderator and variously enriched uranium fuel, that is, its present day version, the coupled fast-thermal system HERBE. A group of research workers, technicians, operators and skilled workmen in the workshop have worked continuously on it. Some of them have spent their whole working age at the reactor, and some a part of it. There is about a hundred and fifty internationally published papers, twenty master's and fourteen doctor's theses left behind them for the past thirty five years. This book is devoted to them. The first part of the text refers to the pioneering efforts on the reactor and fundamental research in reactor physics. The experimental reactor RB was designed and constructed at the time to operate with natural uranium and heavy water. Measurements are presented and the first results of reaching critical state, measurements of migration length of thermal neutrons and neutron multiplication factor in an infinite medium; also measurements of neutron flux density distribution and reactor parameter, and in the domain of safety, measurement of safety rods reactivity. Those were also the times when the

While the RB reactor system was purely thermal with a variable neutron reflector, possibilities for this kind of research were comparatively limited. However, these possibilities were greatly increased by system configurations which had neutron converters built into them, and which created significant and spacious fast neutron fields suitable for various experiments. In the beginning of the eighties at the Institute in Vinca, designing and construction of a fast zero power reactor called LASTA began. The design was completed, location for it examined and arranged. In a mid-phase, even the main design of a subcritical system called MALA LASTA was also elaborated. RB reactor has its role in these designs, which consisted mostly of creation of neutron fields similar to the energy spectrum like the one in the LAST A, intended for basic measurements and acquiring of experimental experience for future experiments. In order to fulfil this task, a hybrid coupled fast-thermal system HERBE was completed, which will, in view of its significance, be devoted a part of this monograph. Reactor RB began its operation as part of the Laboratory for Physics and Dynamics of the Reactor. It was also a Basic Organization of Associated Labour, and now the Nuclear Engineering Laboratory developed around it. All the important data on this several-decades long work are presented in this monograph. (author)}
