A System of Neutronics Computational Benchmarks for VVER Reactors

A system of computational neutronic benchmarks has been developed over the last four years. This system is intended to complement the Atomic Energy Research (AER) benchmarks. This paper presents a summary of the development and a brief description of the benchmarks. The set is primarily comprised of interrelated benchmarks that share situation descriptions and data. The system covers the VVER 440 and VVER 1000 reactors extensively, and in a few cases the newer VVER 640 reactor design. Benchmarks within the system address the static, dynamic (with and without feedback), fuel depletion and fuel loading optimization, and normal as well as accident situations. (author)
