Description

The Dalat Nuclear Research Reactor (DNRR) is the unique pool-type research reactor in Vietnam with the power output of 500 kW. The reactor core was upgraded from a 250 kW TRIGA Mark II research reactor. The DNRR is currently operating with low uranium-enriched (LEU) VVR-M2 fuel type. Kinetics parameters of the reactor core are important parameters to assess the safety operation of the nuclear reactor. In the present work, evaluation of the kinetics parameters, including delayed neutron fraction and prompt neutron lifetime, of the DNRR core loaded with 92 LEU fuel bundles has been conducted using the MCNP 6.2 code and the ENDF/B-VIII.0 nuclear data library. The results show that the delayed neutron fraction at the beginning of cycle is 0.75±0.03 and the prompt neutron lifetime (lp) is 92.31±2.64 (ms). Effect of new nuclear data library (JENDL-5) and the uncertainty of the nuclear data on the calculation results are also being evaluated and presented.
