The quality of the isotopic composition of plutonium fuel degrades as the number of recycles increases in thermal reactors. There are in addition incentives to better utilise fuel by increasing the b...

A wealth of technical information exists on nuclear fuel cycle options – combinations of nuclear fuel types, reactor types, used or spent nuclear fuel (SNF) treatments, and disposal schemes – and mos...

New NEA task force on partitioning and transmutation kicks off

Attitudes towards plutonium management vary from country to country and from utility to utility: some regard plutonium as a liability and others as a valuable source of energy.

The purpose of this st...

Studies on fast reactors have historically concentrated on their capability to use plutonium produced in thermal reactors as initial fuel, and subsequently their capacity to produce electricity while...

The quality of the isotopic composition of plutonium fuel degrades as the number of recycles increases in thermal reactors, requiring an increase in the total loading necessary in mixed plutonium-ura...

The NEA has studied multiple recycling issues associated with various reactor systems fuelled with mixed-oxide (MOX) and published a series of computational physics benchmarks. This has led to improv...

Although the recycling of plutonium as thermal mixed-oxide (MOX) fuel in pressurised water reactors (PWRs) is now well-established on a commercial scale, many physics questions remain. The main quest...

This study updates the 1985 NEA report and presents a comprehensive analysis of the individual and total costs of the nuclear fuel cycle for a pressurised water reactor (PWR) to be commissioned in th...

Fuel cycle technology and innovation relates to all stages of the nuclear fuel cycle, from the latest uranium enrichment technologies to design and implementation of small modular reactors (SMRs).

The goal of the Expert Group on Back-end Strategies (BEST) is to identify aspects of significant importance to countries’ decisions on whether to deploy partially and fully closed nuclear fuel cycles...

The long-term hazard of radioactive waste arising from nuclear energy production is a matter of continued discussion and public concern in many countries. Through partitioning and transmutation (P&T)...
