2018 | AFC ACCOMPLISHMENTS 13 Accomplishments: Instrument capabilities were improved by adding a new Experiment Instru- ment Panel (EIP) on top of the reactor that is connected to the Data Acquisition System (DAS) for use with experi- ments with instrument leads and heater controls completing a Level 2 milestone “Complete design and build experi- ment support equipment to support instrumentation and controls for each experiment.”The EIP was designed and assembled by Eric D. Larsen.TREAT Maintenance personnel installed the new EIP and made the connections to the DAS plus completed System Oper- ability (SO) testing to verify the EIP functions as expected. Instrument capabilities were improved by installing instrumentation into the TREAT reactor during prescription testing. Installed into the core was micro-pocket fission detector (MPFD), self-powered neutron detectors (SPNDs) and optical fibers/pyrometers. Having the instruments in-core during operations has proven the instruments are very reliable.The instrument team included Colby Jensen,Austin Fleming, KevinTsai and theTREAT operations team. Instrument capabilities were improved with a joint nuclear instruments testing inTREAT project with Massachusetts Institute ofTechnology (MIT).A sensor package consisting of four self-powered gamma detectors (SPGD), one SPND, one dual channel MPFD, one single channel MPFD, two typeT thermocou- ples, and one type K thermocouple was installed into theTREAT reactor during temperature limited transients.The project was a proven success.The team includedTREAT operations and experi- ment engineering personnel working with MIT students. TREAT capabilities were proven by the assembly of five Separate Effects Tests Holder (SETH) capsules in the Hot Fuel Examination Facility (HFEF) in preparation AccidentTolerant Fuel (ATF)-3-0 experiment campaign which commenced on September 18, 2018. The assembly included fresh fuel pins, welded thermocouples, fiber optic instrumented leads, filling capsule with helium gas, leak check, and radiography. The assembly team consisted of Nicolas Woolstenhulme, Devin Imholte, Doug Dempsey, ConnorWoolum, Nathan Jerred, Lance Hone,Austin Fleming, and Aaron Craft. TREAT capabilities were improved by designing and fabricating a shielded pig and stand for use to remove a SETH capsule from the primary can.The design was completed by Steve Swanson and Collin Knight; MFC fabrication shop fabricated the pig and stand.These proved to reduce the dose received to workers by a large amount allowing handling of the SETH capsule after the transient experiment.
