Study of Reduced-Enrichment Uranium Fuel Possibility for Research Reactors

Thermal -Hidraolyc Study of Trr Core in Fuel Conversion Frome Highly Enriched Uranium to Low Enriched Uranium Fuel (RESEARCH NOTES)

Minimization of waste from uranium purification, enrichment and fuel fabrication

FOREWORD As any industry, nuclear industry generates a diverse range of waste which has to be managed in a safe manner to be acceptable to the public and the environment. The cost of waste management, the risks to the public and employees, and the detriment to the environment are dependent on the quantity and radioactive content of the waste generated. Waste minimization is a necessary activity...

Modal Analysis of Spent Fuel Cask for WWER-1000 Reactors

The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...

Public Health Risks of Substituting Mixed-Oxide For Uranium Fuel in Pressurized- Water Reactors

The U.S. Department of Energy (DOE) has awarded a contract to the consortium Duke Cogema Stone and Webster (DCS) to dispose of up to 33 tonnes of excess weapons-grade plutonium (WG-Pu) by irradiating it in the form of mixed-oxide (MOX) fuel in four U.S. commercial pressurized-water reactors (PWRs). This paper estimates the increase in risk to the public from using WG-MOX at these reactors and f...

محاسبات مصرف سوخت و پارامترهای نوترونیک مربوط به رآکتورهای آب سنگین تحقیقاتی با سوخت اورانیوم- توریوم توسط کد MCNPX

One of the main characteristics of heavy water research reactors is their high production of plutonium. This work demonstrates the possibility of reduction of plutonium production and other actinides in heavy water research reactors. Among the many ways for reducing plutonium production in a heavy water reactor, in this research, changing the fuel from natural uranium to thorium-uranium mixed f...
