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 reaching theoretical accidental conditions. An out-of-pile experiment was designed to study accelerated inward thermal creep and outward displacement of a cladding that occurs after pellet-cladding interaction. Four different materials deposited by the cold-spray technique were studied as well as the reference uncoated one. The results confirm theoretical prediction that due to a mismatch between the fundamental physical properties of each layer, high stresses will build up and the plastic strains expected will lead to coating cracking.

“…Despite two previous IRPs funded in 2012 with focus on experimental study of metallic and ceramic Zircaloy coated claddings 2 , this IRP still included a coating program. This was a testament to the project leadership's belief that the coated clad concept will be the primarily initial pathway for near term industrialization of ATF technology due to presence of enrichment penalty and licensing hurdles of the alternative clad concepts.…”

The following integrated research project (IRP) was originally led by Professor Mujid Kazimi of Nuclear Science and Engineering (NSE) Department at Massachusetts Institute of Technology (MIT). Without Prof. Kazimi's leadership and experience in this area the formation of such unique team would not have been possible. Professor Kazimi's sudden passing in July 2015 provided major blow to the NSE department and the IRP. Many thanks for Professor Jacopo Buongiorno for providing leadership when needed to take over Prof. Kazimi role and act as a senior advisor to the project. The efforts of Dr. Thomas McKrell who was in charge of the experimental activities of the IRP at MIT require a special acknowledgment before his unfortunate passing in 2017. In addition following individuals are acknowledged:

“…This model was used to analyze the performance of different multi-component claddings considered as potential candidates for the ATF development. Some of the concepts have been developed at the CTU [14] or MIT [15] and some are considered as alternative options and will be investigated in future research. All studied concepts are based on the Zircaloy-4 alloy substrate (isotopic material composition is noted in Table 2).…”

Abstract. The paper summarizes preliminary results of neutronic analysis of candidate ATF cladding materials that are under development at the CTU in Prague. To evaluate basic neutronics-related characteristics the Serpent code was used which is a Monte-Carlo based simulation tool. A model of WWER fuel was developed and basic neutronic analysis performed. All coating materials entail certain reactivity penalty compared to reference uncoated cladding that was quantified. The coating of cladding affects also other neutron-physical parameters of cores that modify the performance of the WWER reactors that are discussed.
