The effect of local power increase on neutron flux in internal parts of the WER-1000 Mock-Up in LR-0 reactor

摘要

The neutron flux distribution in the internal parts of a reactor is an important parameter which affects the absorbed dose, temperature, and gas production in the materials. Therefore, the knowledge of neutron flux distribution, for example in the baffle, is important for estimation of the radiation-induced swelling and activation of this internal component. The power distribution in the periphery fuel assemblies, mostly the lateral 2-3 pin rows, has considerable influence on neutron and gamma flux in the internal reactor elements.
