Autoclave at the Westinghouse Research Laboratory to be used to examine sensor and cladding durability under prototypic PWR and ATR flow conditions prior to ATR insertion. what is learned and developed during this process may be applicable to the design of the next generation of LWRs. The ultimate goal of the Accident Tolerant Fuels (ATF) program is to demonstrate improved fuel and/ or cladding concepts offering the potential to replace the Zircaloy UO2 system currently used throughout the Light Water Reactor (LWR) industry. To support this goal, the congressional appropriation language for FY 2012 included specific language for DOE NE to initiate an aggressive RD&D program for LWR fuels with enhanced accident tolerance.The test data collected as part of the ATF program will support demonstration of Lead Fuel Rods or Lead Fuel Assemblies in a commercial LWR by the end of FY 2022.The ATF 2 ATR water loop experiments are a continuation of the ATF 1 drop-in capsule feasibility experiments with the primary objec- tive of testing ATF concepts under PWR prototypic conditions to demon- strate concept viability. Accomplishments: ATF-2 irradiation testing work performed in FY 2015 included: (1) design and analysis of a Sensor QualificationTest (SQT) in the ATR prior to inserting a fully loaded fueled test train (Figure 1), (2) continued conceptual design and scoping of the ATF-2 fueled test train in preparation for final design analysis, (3) fuel rod assembly development and mock-up demonstrations using dummy fuel rod materials, (4) identification and procurement of assembly equipment such as induction brazing equipment, a laser welder4 axis workcell, and portable x-ray radiography equip- ment, (5) design and planning for an out-of-pile flowing autoclave test replicating ATR water loop conditions for the SQT (Figure 2), and (6) design and procurement of sensors to be used in the autoclave, SQT, and ATF-2 experiments. INL collaborated with the Institute for EnergyTechnologies (IFE) in instrumented lead assembly development, sensor design and preparation for wiring at the ATR, and preparation for the autoclave test. INL is subcontracting the autoclave test support to Westinghouse to utilize existing autoclave equipment at their Churchill, PA research facility. A final conceptual design for the ATF-2 water loop experiment has been established in collaboration with the ATF Industry Partners Westinghouse, General Electric, and AREVA (Figures 3 and 4). The final design informa- tion for each of the Industry Partners is documented in FCRD reports.The final conceptual design will be used to perform final design safety analysis for ATR insertion, finalize design draw- ings, and perform fuel performance analysis for each ATF concept.
