Transitioning to High Assay Low Enriched Uranium-fueled reactors will alter the material requirements of current nuclear fuel cycle, in terms mass enriched uranium and Separative Work Unit capacity. This work simulates multiple cycle scenarios using Cyclus compare how type advanced reactor deployed energy growth demand affect transition reactors. Fuel considered include fleet Light Water Reacto...

Brazilian systematic investigations on the use of thorium fuel cycles in nuclear power reactors started in 1965. During the 60's and early 70's the work was mainly concentrated on the thorium utilization in heavy water reactors (HWRs). This work was performed in the framework of a cooperation agreement with the, French CEA. In the frame of the International Nuclear Fuel Cycle program, Brazil st...

Recently, a second Target Accuracy Requirements (TAR) exercise is launched in the framework of WPEC/S46 on “Efficient and Effective Use Integral Experiments for Nuclear Data Validation”. The TAR aims at quantifying nuclear data needs, terms uncertainty reduction, to meet target accuracies specific integral parameters. These are driven by reactor fuel cycle design. goal provide NEA/HPRL with new...

Fast reactor fuel cycle (FRFC) is regaining importance because of its vital role in the long term development of nuclear power. The safety issues associated with the fast reactors are now well understood and newer designs can address those from the lessons learned in the past. The same cannot be ascertained about their safeguards issues. Primary reason being the presence of special nuclear mate...

The article provides an overview of the FSUE Atomflot activities aimed at improving infrastructure and production facilities for management spent nuclear fuel radioactive waste ensuring nuclear, radiation environmental safety, both in Murmansk region throughout northwestern Russia. Carrying out work within Federal Target Program “Ensuring safety 2016—2020 period up to 2030” cooperation with str...

The basis of the MOX (Mixed OXide) energy equivalence principle is keeping in-core fuel management characteristics (cycle length, feed size, etc.) a nuclear reactor unchanged when replacing UOX (Uranium assemblies by MOX. If effect loading pattern neglected, such an obtained tuning Pu content in fuel, while considering specific isotopic vector at time core reload to obtain crossing reactivity c...

Purpose – Aims to make an industrial robot work as a telemanipulator with force feedback, in order to carry out various tasks for remote handling in nuclear fuel cycle plants. Design/methodology/approach – The robot STABLI RX170 (used as a slave arm) has been fitted with a force-torque sensor and an electronic system for sensors’ signals multiplexing. The overall system has been made tolerant ...

background: nowadays, application of nuclear technology in different industries has largely expanded worldwide. proportionately,the risk of nuclear incidents and the resulting injuries have, therefore, increased in recent years. preparedness is an important part of the crisis management cycle; therefore efficient preplanning seems crucial to any crisis  management plan. equipped with facilities...

The transmutation of spent nuclear fuel is considered as a prospective alternative concept to the current concept based on the non-reprocessed spent fuel disposal into underground repository. The Czech research and development programme in the field of partitioning and transmutation is founded on the Molten-salt Transmutation Reactor system concept with fluoride salts based liquid fuel, the fue...
