Nuclear Power Plant in Indonesia has been planned to be built in Bengkayang Regency, West Kalimantan. Even so, there is a problem related to the local people acceptances due to their lack of understanding about nuclear. The society willingly be agreed if there are any safety and security guarantees alongside the establishment of Nuclear Power Plant on that area. One of the factor that have a radiology impact of radionuclide dispersion in the air is a meteorological factor. Wind conditions in West Kalimantan have the possibility to be impact by the phenomenon of local or global wind. Therefore, a simulation of radionuclide dispersion model in this region will be carried out. This research used the observation data of Mempawah Class II Climatology Station to search the day sample with any kind of wind condition, FNL data with 1ºx1º resolution will be used as an input on WRF model and the observation data of Supadio Class I Climatology Station used to verify the WRF model. Furthermore, the output of the WRF wind model will be used as an input data on CALPUFF. The result of this research indicate that the radius ranges of radionuclide distribution in the air from the Nuclear Power Plant prospective site in normal operation be at minimum of nearly 5-12 km to a maximum of nearly 35 km. Concentration of radioactive substances distribution released by West Kalimantan Nuclear Power Plant prospective site is relatively low and have no potential to danger humans and environment around the Nuclear Power Plant area at a fairly close distance.
