Subject fundamentals
The course deals with environmental themes of energy plants localization and provides knowledge on concept, theory and methods for the evaluation of environmental impacts sustainability and risks linked to construction and operation of energy plants.
With reference to legal framework in the field of environmental protection, the course will provide the criteria for siting and land-use planning.
Models to quantify the impacts both in normal operation and during accidents will be applied.
The Environmental Impact Report (EIR), Environmental Impact Assessment (EIA), Integrated Pollution Prevention and Control will be analysed by examples on real plants and studies.
Expected learning outcomes
At the end of the course the student should:
• know the Legislation regarding preservation of homelands, to be used in the Environmental Impact Assessment (EIA) of energy plants.
• know the fundamental methodologies and models necessary to a proper localization and design of energy plants, in accordance with the present requirements and environmental compatibility;
Prerequisites / Assumed knowledge
Chemistry, Energetics, Nuclear and Thermoelectric plants, Safety and Environmental Impact of Energy Systems Chemistry.
Contents
• Basic concepts of environmental impact assessment (~ 30 h):
- Legal framework for environmental protection procedures and formalities for the acquisition of the necessary permits to begin the construction (with particular reference to the process of Environmental Impact Assessment) and exercise (Integrated Pollution Prevention and Control) of power plants; the system of territorial / environmental constraints; hints of Strategic Environmental Assessment (SEA).
- Insights into the Environmental Impact Assessment (SIA): analysis of site and design alternatives in order to find the optimal solution; hints on identification and application of "best available techniques" (BAT).
- Predictive analysis of the environmental effects generated by energy systems in the phase of construction and operation, with particular reference to the impacts associated with air emissions and noise (study of the "ante operam" environmental status, identification and quantification of impact factors, methods and models for the prediction of impacts, mitigation measures, monitoring activities). Hints of the analysis to be conducted in relation to other environmental components identified by legislation (aquatic environment, soil and subsoil, vegetation, flora and fauna / ecosystems, public health, ionizing and non-ionizing radiations, landscape).

• Accident analysis in energy plants and models for evaluation of the most significant parameters during accidents and the effects on health and environment. Use of predictive models apt to a correct design of systems that prevent and mitigate accidents (~ 70 h):
- Hazardous substances: physical-chemical properties, toxicity, eco-toxicity; legislation governing their classification, labeling and Safety Data Sheets.
- Accidental releases of hazardous materials, gaseous, liquid and two phase flow: failures causes and their prevention; models to evaluate mass and flow rate versus time; prevention and mitigation techniques.
- Liquid pool evaporation: models to estimate the evaporation rate for releases on land within/without bounds.
- Vapour cloud dispersion: hints on calculation models to provide concentrations as a function of time and space in case of turbulent free jet and heavy gas releases.
- Fires: types of fires, models to provide heat flux on the receiver; personal injuries and material damages; prevention and mitigation techniques.
- Explosions: types of explosions, hints on calculation models to estimate the characteristic variables of the shock wave; personal injuries and material damages due to explosions or to fragments originated from the explosion source
Delivery modes
Exercise session in class (~ 22 h):
- Application of the predictive models explained during lectures to practical cases;
- Description of the case studies and available software in LAIB.
Exercise session in PoliTO LAIB (~ 12 h):
- Two exercises on the evaluation of the quality change of air and acoustic environment due to real energy plants are proposed. The software available in PoliTO LAIB will be utilized The exercises will be assigned to group of 4๗6 students and a report is required for each of them.

If possible, a visit to an energy plant in Piemonte will be carried out.

Further material can be provided on the course website.
Assessment and grading criteria
The two reports of the LAIB exercises must be uploaded on the course website at least two working days before the date of the exam.
The exam consists of written test (at LAIB) including both numerical exercises and theoretical open questions regarding the reports and all the topics treated during lessons.
Students who obtain a score ≥ 26 in the written test may ask to have an oral discussion, which will include discussion of the reports and the topics treated during lessons will be verified in depth.
Notes

In case the score of the written exam cannot be determined with certainty, the teacher can required an oral discussion to the student in order to optimize the score.
