During its operations, NPP will release only a small amount of radionuclides in the form of gaseus and liquid effluents due to its high safety standard. Although reports say that the average effective dose to the public due to this release is within the regulatory safety limits, public concerns on health effects resulting from its realease is inevitable. Most common calculations of the cost of electricity have not directly included the health impact component, in other words the cost is external or bear by other party which is the public. Public demanded that the health impact cost be bear by the producer of electricity that is to make this cost internalised by the company. This study aims to determine the external cost of the first candidate of Indonesian 100 MWe NPP in West Kalimantan using the Simplified Approach for Estimating Impacts of Electricity Generation (SIMPACTS) software. We limit our analysis on the health impact of the releases from airbourne pathway through inhalation and external exposure and neglecting the airbourne pathway through food chain that ends up in ingestion. Likewise, we also neglect completely the health impact of the release from waterbourne pathway. The result shows that the health impact cost for a 100 MWe NPP within the study area is 72.16 USD/year or 8.838×10−6 cents/kWh and does not have significant impact on the cost of electricity. It also shows fatal cancer 0.005 cases/year, non-fatal cancer 0.016 cases/year and specific hereditary effects 0.00025 cases/year, which means that the incidence cases for the health impact of 100 MW NPP in one year can be said to be non-existent. The determination of the impact cost value needs to be discussed by related parties, including the health authorities so that the amount of responsibility can be accepted by all parties.
