چکیده
صنعت برق از صنایع زیربنایی می‌باشد و توسعه اقتصادی و اجتماعی بدون آن امکان‌پذیر نخواهد بود. در عین حال نیروگاه‌های برق در مرحله ساخت و بهره‌برداری تأثیر به‌سزایی بر محیط‌زیست دارند. از این‌‌رو ضروری است که جهت کاهش مخاطرات و پیامدهای سوء ناشی از فعالیت نیروگاه اقدامات مدیریتی مناسب اتخاذ نمود. این مقاله با هدف ارزیابی و رتبه‌بندی ریسک‌های محیط‌‌زیستی نیروگاه سیکل ترکیبی در مرحله بهرهبرداری انجام شده است. پس از شناسایی ریسک‌های محیطزیستی، با استفاده از روش آنالیز مقدماتی خطر (PHA) و براساس معیارهای شدت و احتمال وقوع عوامل مخاطره آمیز ارزیابی و سطح ریسکها محاسبه گردید. سپس برای اولویتبندی جنبه‌‌های بارز محیطزیستی، از روش مارکوس استفاده شد. بر اساس نتایج به‌دست آمده، از میان ریسکهای محیطزیستی شناسایی شده، جنبههای انتشار گازهای احتراقی با عملکرد مطلوبیت 741/0، تولید پسماندهای صنعتی با درجه مطلوبیت 738/0 و انتشار گاز در اثر پوسیدگی و یا ترکیدگی لوله‌های انتقال با مطلوبیت 708/0 به‌عنوان مهمترین جنبههای محیطزیستی نیروگاه مورد مطالعه تعیین شد. در نهایت اقدامات اصلاحی و کنترلی برای کاهش ریسکهای محیطزیستی ارائه گردید.

چکیده English

The electricity industry is one of the fundamental infrastructure sectors, and economic and social development cannot be achieved without it. At the same time, power plants exert significant environmental impacts during both construction and operational phases. Therefore, it is essential to adopt appropriate management measures to reduce the risks and adverse consequences arising from power plant activities. This study aimed to assess and prioritize the environmental risks of a combined cycle power plant during its operational phase. Following the identification of environmental risks, the Preliminary Hazard Analysis (PHA) method was employed to evaluate risk factors based on the criteria of severity and probability of occurrence, and the corresponding risk levels were calculated. Subsequently, the MARCOS (Measurement Alternatives and Ranking according to the Compromise Solution) method was applied to prioritize the significant environmental aspects. The weighting of criteria was determined using the Shannon Entropy method. The results indicated that among the identified environmental risks, combustion gas emissions, with a utility degree of 0.741, industrial waste generation, with a utility degree of 0.738, and gas leakage resulting from corrosion or rupture of transmission pipelines, with a utility degree of 0.708, were identified as the most significant environmental aspects of the studied power plant. Finally, corrective and control measures were proposed to mitigate environmental risks and improve environmental performance.
