AGR-5/6/7 Irradiation Test Final As-run Report
This document presents the as-run analysis of the Advanced Gas Reactor (AGR)-5/6/7 irradiation experiment. AGR-5/6/7 is the last of a series of experiments conducted in the Advanced Test Reactor (ATR) at Idaho National Laboratory in support of the development and qualification of tri-structural isotropic low-enriched fuel for use in high-temperature gas-cooled reactors. The test train […]
Future TRISO fuel irradiations in the Advanced Test Reactor
AGR-5/6/7 was thought to be the last experiment in the AGR series and the last experiment directly sponsored by DOE. Over the last five years three developments have caused a reevaluation of that assumption. First is that interest in TRISO fueled reactors has spiked dramatically. Virtually all of the new reactor designs are for SMRs […]
Complete high temperature test of neutron flux sensors in NRAD
The purpose of this test was to characterize operation of Self Powered Neutron Detectors (SPNDs) at high temperature and shake out any bugs in the data acquisition equipment prior to testing at higher flux in MITR.
AGR-5/6/7 Experiment Monitoring and Simulation Progress
Advanced Gas Reactor (AGR)–5/6/7 is the last of a series of AGR experiments conducted in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) in support of development and qualification of tri-structural isotropic (TRISO) low-enriched fuel for use in high temperature gas-cooled reactors. The test train contains five separate capsules that are independently controlled […]
Irradiation Testing of Nuclear Flux Sensors – Presentation for 2021 ASI Annual Webinar
This power point presentation is a summary of the work produced in FY2021 under the Irradiation Testing of Neutron Flux Sensors project funded by DOE’s Advanced Sensor Initiative, and the outlook for FY22. The objective of this portion of the ASI program is to “Test and demonstrate in-pile instrumentation in conditions similar to those expected […]
Summary of Thermocouple Performance in the Advanced Gas Reactor Experiment AGR-5/6/7 During Irradiation in the Advanced Test Reactor
This is a conference presentation ppt file. The following abstract is for the entire conference paper – which will later be the subject of a PRS artifact The Advanced Gas Reactor -5/6/7 (AGR-5/6/7) experiment was the fourth and final experiment in the AGR experiment series and completed irradiation in July 2020. It serves as the […]
Completion of Irradiation of Sensors in ATRC Milestone
This set of PowerPoint slides demonstrates how milestone “M2CT-21IN0702023: Perform test of neutron flux sensors in the Advanced Test Reactor Critical Facility”. It supports an entry in PICS claiming achievement of the milestone. These slides provide a good summary of the purpose and impact of the milestone for our DOE Headquarters colleagues.

Development and Test Results of Thermocouples Used in the TRISO-Fuel Irradiation Experiment AGR-5/6/7
High-temperature gas reactor experiments create unique challenges for thermocouple-based temperature measurements. High-temperature industrial thermocouples suffer rapid decalibration due to transmutation of the thermoelements from neutron absorption. For lower temperature applications, Type K and Type N thermocouples are affected by neutron irradiation only to a limited extent. But until recently, the use of these nickel-based thermocouples […]
