Reactor neutronic investigations on lr-0 reactor

Objective

Zero power reactor LR-0 available at Nuclear Research Institute Rez is an unique experimental tool which allows to model VVER and also PWR cores in 1:1 scale, to use lattices of hexagonal and square geometry, to measure the basic neutronic core parameters. It is eminently suitable for the verification of neutronic codes, measurements of pin-wise fission density distribution, experiments connected with compact fuel storage (VVER-440 and VVER-1000), investigations of burnable absorber influence on neutronflux distribution, gamma-fields.

Examples of LR-0 capabilities:
- Extension of experimental database and modelling capability with respect to control rod influence on power peaking. A special advantage (already available VVER cores) is expected for VVER-440 modified fuel designs with different absorber and fuel materials;
- Experiments for the purposes of verification and validation of computer codes used for computations of cores with burnable absorber.
