1 Transient Reactor Test Loop (TRTL) Model Development Emory Brown WORKING GROUP MEETING FLL 2016 TSK 2 BREKOUT SESSION BOSTON, M

2 Outline Task Description Current Model Status With model projections Preliminary TRCE/RELP5 comparisons Problem description report 1

3 Task 2.2 Overview 2

4 Task : Modeling of benchmark test with TRCE OSU will develop a TRCE model for one of the benchmark tests performed using the U.S. NRC code TRCE. Modeling of the benchmark test will be done blindly, based on the design package put together as a part of task The data will not be made available until the modeling and results have been completed. 3

5 Transient Reactor Test Loop Model Currently Hydraulic Loop Simplified pump Variable area check valve Simplified Tee offtake at exit Heat Structures Heat flux annulus heater rod Simple heat exchanger BCs 4

6 5

7 6

8 Pump Currently Single Junction Components (SJC) with constant liquid and vapor velocities Near Future Controlled SJC pump for transient ramps and test section flow matching. Include fluid volume heating for pump inefficiency. Ultimately Fully implemented pump curve. Head loss vs flow rate. Frictional heating. Impeller momentum for ramp up and coast down. 7

9 8

10 Check Valve Currently Controlled flow area vs P. 1 st order lag implemented to eliminate chatter. Full close at 1.47 psi. Full open at 14.7 psi. Near Future K value implemented along with flow area vs P. djust full open and close stops. Ultimately Develop flow curve based on actual operation for lookup table based implementation. 9

11 10

12 Heated Test Section Currently Heat flux BC on paper thin Nichrome annulus. Table based heat flux vs time. 3 point interpolation pulse shape (triangle). 10 axial nodes. Biasi CHF correlation. Near Future True pulse shape input. Psuedorepresentative heat structure (contains representative mass and averaged thermal properties). Ultimately True geometry (as much as possible). Sufficient radial and axial nodes. Power input and profile based on experimental data. 11

13 12

14 Test Train Exit and Expansion Region Currently Offtake from pipe component to create a tee from which fluid Near Future More representative geometry at expansion. K value implemented between test train and pressure shell Ultimately Determine actual fill level of loop. Even more resolved geometry for fluid bypass regions (purple in previous slide) 13

15 14

16 Heat Exchanger Currently SS 316, 3 radial nodes heat structure. Constant velocity and temperature fluid fill. Near Future Higher nodalization (if necessary). More representative fluid fill. Ultimately Final nodalization. Possibly heat rejection via simplified HX to atmosphere. 15
