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

Conceptualizing a Water Loop Test in TREAT

15

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)
