This paper presents the neutronics benchmark analysis of the first core of the Indonesian multipurposeresearch reactor RSG-GAS (Reaktor Serba Guna G.A. Siwabessy) calculated by the Serpent Monte Carlocode and the newly released ENDF/B-VIII.0 nuclear data library. RSG-GAS is a 30 MWth pool-type material testing research reactor loaded with plate-type low-enriched uranium fuel using light water as acoolant and moderator and beryllium as a reflector. Two groups of critical benchmark problems arederived on the basis of the criticality and control rod calibration experiments of the first core of RSG-GAS. The calculated results, such as the neutron effective multiplication factor (k) value and the control rodworth are compared with the experimental data. Moreover, additional calculated results, including theneutron spectra in the core, fission rate distribution, burnup calculation, sensitivity coefficients, andkinetics parameters of the first core will be compared with the previous nuclear data libraries (interlibrary comparison) such as ENDF/B-VII.1 and JENDL-4.0. The C/E values of ENDF/B-VIII.0 tend to beslightly higher compared with other nuclear data libraries. Furthermore, the neutron reaction crosssections of 16O, 9Be, 235U, 238U, and S(a,b) of 1H in H2O from ENDF/B-VIII.0 have substantial updates;hence, the k sensitivities against these cross-section changes are relatively higher than other isotopes inRSG-GAS. Other important neutronics parameters such as kinetics parameters, control rod worth, andfission rate distribution are similar and consistent among the nuclear data libraries
