In response to the Fukushima Daiichi accident, the development of advanced technology and accident tolerance fuels (ATFs) aims to enhance accident tolerance. The International Atomic Energy Agency (IAEA) launched a Coordinated Research Project (CRP) on Testing and Simulations for ATFs (ATF-TS) in 2020, which consists in four key Work Tasks (WTs) [1]. The work task 3 aims at development and...
In the frame of various Euratom and other international projects, (enhanced) accident tolerant fuel properties (ATF) have been implemented in the TRANSURANUS fuel rod performance code of the JRC. The impact of ATF has been addressed in different studies by means of the TRANSURANUS code. In the first study the focused was on steady-state performance in a case of the coordinated research project...

Following the successful Coordinated Research Project (CRP) on Fuel Modelling in Accident Conditions (FUMAC) [1][2], the International Atomic Energy Agency (IAEA) initiated a new CRP ATF-TS in 2021 to support the development and evaluation of Advanced Technology and Accident Tolerant Fuels (ATFs) [2].
TRACTEBEL's contribution to the CRP ATF-TS focused on developing a methodology to assess...

Enhanced accident tolerant fuel (EATF) were developed in the wake of Fukushima accident to provide some delays in case of severe accident. Today the highest TRL product is clearly coated cladding, more specifically chromium coated cladding.
EDF is currently investigating the benefits that would be provided by EATF in its own plants. Some lead test rods are irradiated. They reached their first...
In the era of rapidly advancing technologies, the capacity of regulatory bodies to conduct thorough and timely safety reviews has become increasingly critical. Approaches to evaluate novel nuclear fuel technologies vary across regulatory bodies; however, a shared objective remains to assess the safety benefits of advanced fuels, particularly Accident Tolerant Fuels (ATFs) and to shape future...
In the United States, recent legislative actions and executive orders have spurred significant interest in utilizing advanced fuel technologies and analytical approaches to support power uprates and extended cycles at current operating boiling and pressurized water reactors. To facilitate efficient and timely licensing reviews while continuing to protect public health and safety, the U. S....
