Accident Tolerant Fuel Analysis [PDF]
, 2014 Safety is central to the design, licensing, operation, and economics of Nuclear Power Plants (NPPs). Consequently, the ability to better characterize and quantify safety margin holds the key to improved decision making about light water reactor design, operation, and plant life extension.

Material Selection for Accident Tolerant Fuel Cladding [PDF]
Metallurgical and Materials Transactions E, 2015 Alternative cladding materials to Zr-based alloys are being investigated for accident tolerance, which can be defined as >100X improvement (compared to Zr-based alloys) in oxidation resistance to steam or steam-H2 environments at ≥1473 K (1200 °C) for short times.

On the oxidation mechanism of U3Si2 accident tolerant nuclear fuel
Corrosion Science, 2020 The oxidation mechanism and products of U3Si2 accident tolerant nuclear fuel in flowing air up to 750C is reported. Differences between observed and theoretical mass gains for complete oxidation is due to un-oxidised Si that forms nano-crystalline regions of Si.

STUDY OF THERMAL CREEP OF COATED CLADDING MATERIALS
Acta Polytechnica CTU Proceedings, 2018 Coated cladding materials are considered as a near-term concept for so-called Accident Tolerant Fuel materials. Their behavior in accidental conditions is mainly studied around the world, however, they need to survive in-reactor normal operation before ...

Accident tolerant fuels to replace uranium dioxide
Journal of Physics: Conference Series, 2020 Abstract The thermal conductivities for the traditional fuel UO2 and for the Accident Tolerant Fuel (uranium Molybdenum alloy, U-10Mo and uranium silicide, U3Si2) are calculated and compared. Then the temperature distributions on these core reactor, namely on the surface of the rod and in the center line of the rod were determined.
