Assessment of potential human health and environmental impacts of a nuclear power plant NPP based on atmospheric dispersion modeling. What does environmental impact stand for December 15, ; accepted October 13, Se utilizaron factores de escala para valorar el posible efecto radiológico externo sobre la biota humana y no humana. Mientras que los efectos radiológicos sobre seres humanos se examinaron mediante los métodos computacionales comunes establecidos por las autoridades regulatorias, respecto de la biota no humana se eligió un enfoque integral para la valoración y manejo de riesgos ambientales debidos a radiación ionizante D-ERICA.

Sin embargo, los accidentes caracterizados por precipitación sí provocarían riesgos radiológicos perceptibles dentro de la zona delimitada en el plan de emergencia de la PEN. The code has produced values of the scaling factors for ground level air concentrations and depositions of radionuclides from the passing plume over our areas of interest. The scaling factors have been used to assess the potential radiological impact on the offsite human and non-human biota.

While the radiological impacts on humans were calculated using the popular computation methods set by regulatory authorities, an integrated approach to the assessment and management of environmental risks from ionizing radiation D-ERICA was adopted for the non-human biota. The results of this work indicate that, under normal operations, the NPP does not pose any significant public health and environmental impacts.

However, accidental conditions what does environmental impact stand for by precipitation will lead to discernible radiological risks within the NPP sites emergency planning zone. Nigeria is planning to add nuclear energy to its energy sources in order to address its energy crisis. According to the country's nuclear power deployment roadmap, the country's pioneer nuclear power plant NPP is to generate MW by with a plan to increase the generating capacity to MW by Countries around the world are considering the adoption of nuclear power due to its low greenhouse gases emissions, which is vital for climate change mitigation.

However, strict regulatory mechanisms standards must be fulfilled before an operation license or even a construction license is given for a new nuclear power program. This regulatory standards include the estimation of potential radiological risks to both humans and environment from routine and accidental releases of radionuclides from the new NPP. In a situation where measurements are not available, the assessment could be achieved through modeling using computer codes. The models to be used in the current study consider the radionuclides transfer factor and the exposure pathway in the estimation of radiological consequences.

All computations lie within the what does environmental impact stand for of the system of radiological protection recommended by the International What does environmental impact stand for on Radiological Protection ICRP. Computer models are now an important part of the environmental health and safety assessment. The study what does environmental impact stand for improvement of techniques in atmospheric dispersion modeling of radioactive effluent in risk assessment and emergency response date back to half a century ago Abdul Basit, ; Yao, To achieve some of the regulatory recommendations, it is necessary to use robust environmental modeling techniques.

The AERMOD model has been used for accurate dispersion calculation of radioactive fallouts from the incineration of urban solid wastes Ronchin et al. Radiological consequence assessment of atmospheric releases from a new NPP is an important regulatory criterion that must be fulfilled before the construction and operation licenses are issued to operators of NPPs. Hence, the aim of this work is to use internationally verified and state of the art models to estimate the potential human health and environmental impacts of new nuclear programs in Nigeria for the first time.

The description of the parameters considered in the GPM is presented in Figure 1. The Gaussian distribution provides a solution for the random walk problem and it was considered to be a fundamental solution for the diffusion equation. The models that are based on the assumption that concentration can be described by normal distribution are called GPMs Sorbjan, These models were developed by Pasquill and they are based on Eq. Q is the emission factor rateand is the downwind factor Schulze and Turner, ; Sorbjan, Environmental Protection Agency US EPA initiated a formal collaboration with the aim of introducing current planetary boundary layer PBL concepts into regulatory dispersion models in AERMET uses meteorological data and surface roughness information to compute the BL parameters like mixing height, friction velocity, etc.

These data are representative of the climatology in the modeling domain. On the other hand, AERMAP uses gridded terrain data of the domain to calculate the representative terrain-influence height associated with each receptor's location. The terrain pre-processor can also be used to compute elevations for both discrete receptors and receptor grids Cimorelli et al.

In recent years, for most air quality applications the modeller is concerned with dispersion in the PBL, the turbulent air layer next to the earth's surface that is controlled by surface heating, friction and overlying stratification. The PBL typically ranges from a few hundred meters in depth at night to km during the day Cimorelli et al. In the PBL, the wind speed and wind direction are affected by frictional interaction with objects on the surface of the earth Schulze and Turner, AERMET uses three different meteorological data: data of the source location onsitedata of the offsite location, which is used to complete the onsite meteorological data, and data of the upper air from a location near the source Caputo et al.

AERMOD handles the calculation of pollutant impact in both flat and complex terrain within the same computational framework, thereby removing the need to specify whether the modeling domain is flat or elevated, which is necessary in most regulatory dispersion models Cimorelli et al. Details of the model formulation theories and methodologies adopted are available in literature Cimorelli et al.

A brief description of these models based on their analytical formulation is presented below. This model uses an advanced Gaussian approach with a normal Gaussian distribution in stable and neutral conditions, whilst the vertical dispersion is approximated by two different Gaussian distributions in a CBL. The treatment of the reflection of the plume on the surface of the Earth is similar to other Gaussian models. The model calculates the plume rise based on temperature differences between the atmosphere and the emitted plume, and horizontal and vertical momentum fluxes including the possibility for entrainment of the plume and its escape through inversion at the top of the boundary layer.

The dry deposition of particles is modeled as a function of gravitational settling and deposition velocity with respect to aerodynamic, sub-layer and surface resistances. Wet deposition is approximated using a washout coefficient derived from the precipitation rate Holmes and Morawska, The California Puff Model CALPUFF is a non-steady-state Gaussian puff model containing modules for complex terrain effects, overwater transport, coastal interaction effects, building downwash, wet and dry removal, and simple chemical transformation Scire et al.

Just like AERMOD, it models four different types of sources: point, line, volume and area using an integrated puff formulation Holmes and Morawska, It also takes into account the effects of plume rise, partial penetration, buoyant and momentum plume rise, stack effects and building effects. Details of the model formulation are presented in Scire et al. It is a global model, i. The input data are interpolated to an internal sub-grid centered to reduce memory requirements and increase computational speed.

Calculations may be performed sequentially or concurrently on multiple meteorological grids, usually specified from fine to coarse resolution Draxler and Hess, ; Draxler et al. Air concentration calculations relate the mass of the pollutant with the release of either puffs, particles, or a combination of both. The dispersion rate is calculated from the vertical diffusivity profile, wind shear, and horizontal deformation of the wind field.

Air concentrations are calculated at a specific grid point for puffs and as cell average concentrations for particles Draxler and Hess, Insight on the model formulation is presented below; for details see Draxler and Hess and Draxler et al. The meteorological parameters at each horizontal grid point are what does environmental impact stand for interpolated to an internal dispersion model terrain-following a coordinate system as shown in Eq.

The model internal height above the ground level AGL can be chosen at any interval. The aim of this project was to develop an approach whereby the environmental impacts of ionizing radiation could be quantified and to ensure that decisions on environmental issues gave appropriate weight to the exposure, effects and risks from ionizing radiation. Incorporated in the modeling what does environmental impact stand for are databases on transfer, dose conversion coefficients and radiation effects on non-human biota that have been developed specifically for the purpose of the integrated approach.

What is a shared connection on linkedin are three elements of the ERICA integrated approach intended to aid decision-making related to the environmental effects of ionizing radiation: assessment of environmental exposure and effects using the ERICA Tool, risk characterization, and management of environmental risks Beresford et al.

Tier 1 is designed to be simple and conservative, requiring a minimum of input data and enabling the user to exit the process and exempt the situation from further evaluation, provided the assessment meets a predefined screening criterion. The risk quotient RQ is then obtained by comparing the input media concentrations with the most restrictive EMCL for each radionuclide. These are defined by Eq. Tier 2 allows the modeler to be more interactive by changing the default parameters screening dose what does environmental impact stand for and radionuclides and selecting specific reference organisms.

The evaluation is performed directly against the screening dose rate, with the dose rate and RQs generated for each reference organism selected for assessment. A 'traffic light' system is used to indicate whether the situation can be considered:. The basic equations for the Tier 2 assessment are shown in Eqs. In this case, the environmental risk is arguably what is setting in social work and the assessment is aakash online classes for class 11 fees at this stage.

In Tier 2, the total risk quotient is calculated as shown in Eq. Tier 3 is a probabilistic risk assessment in which uncertainties within the results may be determined using sensitivity analysis. The assessor can also access up-to-date scientific literature which may not be available at Tier 2 on the biological effects of exposure to ionizing radiation in a number of different species.

Together, these elements allow the user to estimate the probability or incidence and magnitude or severity of the environmental effects likely to occur and by discussion and agreement with stakeholders, to determine the acceptability of the risk for non-human species. Situations that give rise to a Tier 3 assessment are likely to be complex and unique, and it is does hpv cause all cervical cancer impossible to provide detailed or specific guidance on how the Tier 3 assessment should be conducted.

The requirement to consider factors such as the biological effects data within the FREDERICA database, or to undertake ecological survey work, is not straightforward and requires an experienced, knowledgeable assessor or consultation with an appropriate expert Beresford et al. An analysis of meteorological data shows that the wind blows most frequently from the SW with a maximum speed of 8. A predominantly what does environmental impact stand for wind will transport radioactive effluent over north-central Nigeria.

It is mainly rainfall which will determine the deposition of radionuclides to the ground and hence the radiation dose due to ingestion and ground shine. Based on a nationwide study of the annual rainfall in Nigeria, the modeling domain lies within the region with relatively moderate rainfall and a dry season in November through January.

The deposition rate should be higher in April, May and the third quarter of the year. During these periods, the hourly precipitation is high. Figure 3 demonstrates the variation of the hourly relative humidity with seasons. The deposition rates at different receptor points locations are linearly dependent on the receptors' what does environmental impact stand for from the proposed NPP site and the differences in typical rainfall amounts at the locations.

The release temperature is assumed to be 20 o C and no nearby buildings contribute to building wake effects. The stack internal diameter and velocity were assumed to be 4 m and 10 ms -1respectively. In each of the model runs, half-life and deposition are the representative characteristics of the radionuclide under consideration. AERMOD provides the scaling factors for annual average concentrations Bq m - 3 and total deposition Bq m - 2 at each of the four receptors.

The annual average deposition rates Bq m - 2 S - 1 were calculated using a similar method for deposited particles and mean h deposition rates. Annual discharges for each of the nine radionuclides from the proposed site have been modeled separately to derive individual annual scaling factors for average air concentrations Bq m -3 and total depositions Bq m These scaling factors were multiplied by the site-specific annual discharge rates Table I to assess the long-term impact of routine discharges.

Scaling factors, air concentrations, depositions and consequently radiation doses to a reference group within the modeling domain have been calculated for each of the what does environmental impact stand for and each radionuclide. This what does environmental impact stand for allows future updating of the assessment once the type and number of reactors to be built at each site has been decided McMahon example of empty set in real life al.

It is important to mention that a number of isotopes are not considered by the current study and the choice of these radionuclides was based on their volatility and long term importance in radiation protection. In the case what are the disadvantages of seven-segment display hypothetical accidents, an analogous scenario considered to the Fukushima Dai-ichi nuclear accident was.

Several attempts have been made to determine the release rates as well as the radiological impact of the accident, and none of these works has reported a single case of death that is radiation-related Chino et al. Chino et al. These authors coupled environmental monitoring data with atmospheric dispersion simulations under the assumption of a 1 Bq h -1 unit-release rate. They had already applied this method to the Chernobyl accident.
