Estimación del impacto de un hipotética liberación accidental de material radiactivo considerando contramedidas.

Abstract

This integrative final project analyzed the radiological impact of a hypothetical accident at a generic nuclear power plant and the effect of implementing different countermeasures. WinMACCS was used to calculate the atmospheric dispersion of the released radioactive material and the resulting doses to the public. This same code was used to calculate the economic impact of the accident and the countermeasures. In addition, a Python programming language was developed to calculate the Individual Radiological Risk (IRR) and graph it using contour lines. Eight cases were defined in which different short-term countermeasures were applied, including sheltering, evacuation, temporary relocation, and the provision of potassium iodide tablets. In some cases, only one of the countermeasures was applied across the entire area, while in others, they were applied progressively and in different areas. When evaluating the effects of countermeasures, their complexity and costs, it was determined that the most favorable case is the one in which the population present within a circular area of 10 km around the plant is sheltered and then evacuated, the population outside this area is relocated according to an established effective dose limit, and KI tablets are supplied to 50% of the population.
