Current Status of Hardware
May 29, 2017
11
Shakedown (2.2.5) Activities
• Preliminary Wire Tracing for DAS and PLC complete
• Preliminary P&ID Walkthrough (Mechanical Systems/Components) complete
• Controls System in progress (40% complete)
May 29, 2017
12
Operations and Benchmarking Tests (2.2.6)
• Role of TRTL is to provide as much useful information (qualitative and quantitative) for development and implementation of water loop test section in TREAT
• Scientific questions steer the focus of engineering; experimentation provides the feedback
• Consider the ‘life cycle’ of a water loop test in TREAT
May 29, 2017
13
Conceptualizing a Water Loop Test in TREAT
• Determine the form factor
• Loading fuel and instrumentation in HFEF
• Preparing the loop for testing• Water fill• Pre-emptive pressurization• Gas Fill/Purge

Operations and Benchmarking Tests
• TRTL can emphasize: • Optimization of test prep procedures• Instrumentation and equipment
loading/unloading/performance• Various cladding types (SS, Zirc-4, etc.)
• Benchmarking tests are a natural extension/continuation from operations tests
May 29, 2017
16
Benchmarking Tests
• Three types of benchmark tests:• Steady-state, no external heat added• Steady-state, additional heat source• Unsteady, heated
• Call on parameter space defined in previous TREAT/RIA tests for boundaries on energy deposition
• Gradual ramp tests for the pulse heater
May 29, 2017
17
Benchmarking Tests• TREAT capabilities are still being
determined, but historically produced pulses for sodium loop tests
• Bridging the gap between TREAT and LWR RIA (pulse) conditions
• Based on guidance from INL and lit review for pulse and energy deposition ranges, our target ramp duration is 25-50 ms for high energy pulses (> 100 kW)
• Investigate longer ramp durations at lower energies

Next Steps
• 30-60 days• As-built drawings (2.2.11 & 2.2.12)• Pre-Conditioning Pulse Heater installation• Controls System commissioning• Complete Operations Testing• Procure Cladding Sleeves for Benchmarking
• 90 days• Analysis and Evaluation of Operations Testing• Begin Benchmarking Testing• Progress on TRACE and R5-3D Models
• 180 days• Completion ‘in sight’ for Benchmarking Testing,
TRACE and R5-3D Models• Analysis of Completed (to date) Benchmarking
May 29, 2017
19
Topics for Discussion
• What parameters/techniques should TRTL operations tests emphasize?
• How well can TRTL align with previous transient modes?• Temperature limited• Shaped transients• Extended power transients
• Limiting scope of benchmarking tests to take advantage of previous TREAT campaigns (e.g. limited access to TREXR)
