2018 | AFC ACCOMPLISHMENTS 26 The overall objective of this program is to introduce EnCore®*,Westinghouse’s accident tolerant fuel (ATF), lead test rods and lead test assemblies (LTRs/ LTAs) for coated zirconium cladding with ADOPTTM* (a doped UO2) and UO2 and SiGATM** SiC with U3Si2 fuel into commercial reactors by 2019 and 2022, respectively.The objective of the current work is to design, test and build LTRs using commercially scalable technologies for up to 6 year-long exposure at pressurized water reactor (PWR) conditions using U3Si2 and Cr coated Zr alloy cladding. Test programs at MIT and ATR support the LTR work. The data from this 6-year test reactor exposure and test evaluation will be used as the basis to license and load LTAs into commercial reactors. • EnCore and ADOPT are trademarks or registered trademarks of West- inghouse Electric Company LLC, its affiliates and/or its subsidiaries in the United States of America and may be registered in other countries throughout the world.

EnCore fuel will provide not only significant fuel cost savings, but also enable operating cost savings for current nuclear plants due to the reclassification of safety related equipment and testing requirements to lower safety classifications due to enhancement of the ability of the fuel to better withstand beyond design basis events.
