چکیده
عملکرد سیکل‌های تولید قدرت و حوادث مربوط به آنها از موضوعات اساسی حوزه ایمنی نیروگاه‌ها به شمار می‌رود. در صورتی که به هر دلیلی این حوادث به‌درستی مدیریت نشود عواقب آن جبران‌ناپذیر خواهد بود. در این میان نقش عملکرد اپراتور می‌تواند یکی از تاثیرگذارترین فاکتورها در زمان وقوع حوادث باشد. در این پژوهش عملکرد اپراتور در حادثه شکست خط لوله اصلی بخار متصل به توربین به همراه فقدان کامل آب تغذیه برای نیروگاه تولید توان بوشهر مورد ارزیابی قرار گرفته است. در ابتدا داده‌ها در حالت پایا و گذرا با گزارش نهایی آنالیز ایمنی نیروگاه بوشهر به عنوان یک مرجع قابل اعتماد صحت‌سنجی شده که نتایج به دست آمده نشان از تطابق مناسب و منطقی در شرایط زمانی دارد. در ادامه نقش عملکرد اپراتور به‌منظور کنترل پارامترهای ترموهیدرولیکی اعم از دما و فشار مورد ارزیابی قرار گرفته است. در نهایت نیز با انجام آنالیز حساسیت روی عملکرد اپراتور در حادثه شکست خط لوله اصلی بخار به همراه فقدان کامل آب تغذیه، حداکثر زمان احتمالی برای دخالت اپراتور برای مهار حادثه ۷۶دقیقه برآورد شده است.

چکیده English

The operation of power generation cycles and their related events are one of the main issues in the field of safety of power plants. If these events are not properly managed for any reason, the consequences will be irreparable. In the meantime, the operator action can be one of the most effective factors in the management of the accident. In this research, the operator action has been evaluated in the main steam line break connected to the turbine and total loss of steam generator feed water for the Bushehr power plant. Firstly, the data has been validated in both steady and transient states with the final safety analysis report of the power plant of Bushehr as a reliable reference. The results indicate a good agreement with the final safety analysis report. In the next step, the operator action has been evaluated to mitigate the thermohydraulic parameters, including temperature and pressure. Finally, by performing an operator sensitivity analysis in the main steam line break connected to the turbine followed by total loss of steam generator feed water, the maximum possible time for operator intervention has been estimated 76 minutes.
