	Effects of Notches on the Intermediate Creep-Rupture Life of Alloy 617 Weldment	Effects of Notches on the Intermediate Creep-Rupture Life of Alloy 617 Weldment	Fast Reactor Structural	A Code Case has recently been completed that adds Alloy 617 to Section III, Division 5 of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, which covers high temperature nuclear components. However, additional information is needed to address concerns raised by the Nuclear Regulatory Commission that are not covered by the Code Case.	9/16/2020
	Status of INL Aged A709 Mechanical Testing	Status of INL Aged A709 Mechanical Testing	Fast Reactor Structural	A709 was selected to be qualified in Section III, Division 5 of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code. Idaho National Laboratory (INL), Argonne National Laboratory and Oak Ridge National Laboratory are collaborating to develop and qualify A709 plate. Aging A709 to form beneficial precipitates prior to service is investigated. One tensile test, five creep-rupture tests, and eight cyclic tests have been completed on aged A709. Two creep-rupture tests are in progress.	8/24/2020
	Single-Bar SMT Testing on Alloy 617 using Software Controls	Single-Bar SMT Testing on Alloy 617 using Software Controls	Fast Reactor Structural	NL has performed simplified model testing using a variable in the software control program to compare with the testing performed at ORNL, which uses hardware to modify the control signal. The INL tests compared well with the ORNL tests, showing similar stress and strain values, as well as similarly shaped hysteresis loops. This demonstrates that possibility of performing simplified model testing without any hardware modifications.	7/25/2020
