چکیده

عناصر پرتوزا در قلب رآکتور پژوهشی تهران با استفاده از کد محاسباتی 2.1 ORIGEN بررسی شدند. ابتدا، برای اطمینان از نحوه­ی مدل­سازی، نتایج با نتایج «گزارش تحلیل ایمنی رآکتور پژوهشی تهران (SAR)» برای قلب مشابه، مقایسه شد. پس از اطمینان از درستی نتایج، محاسبه برای قلب C-57 رآکتور، انجام شد. براساس نتایج حاصل و با استفاده از کدهای مربوطه، امکان ارزیابی اثرهای پرتوشناختی ناشی از آزاد شدن عناصر پرتوزا در صورت بروز حادثه­ی فرضی محتمل در رآکتور پژوهشی تهران فراهم شد.

چکیده [English]

Core radionuclide inventories calculations were performed for Tehran Research Reactor (TRR) using computer code ORIGEN 2.1. At first a comparison was made between the present calculations and the existing results for the source terms of the equilibrium core that had already been presented in the Safety Analysis Report (SAR), which showed a good agreement. Then, the core radionuclide inventories calculations were carried out for a recent TRR core configuration. The resulting source terms may be used for the evaluation of radiological consequences of the corresponding accidental release of the radio nuclides from the TRR.
