Title:

Cortu'm-Coolant Interactions Fin No.: A1030 Contractor: Sandia Site: Albuquerque State: New Mexico NRC Technical Monitor: J. L. Telford Principal Investigators: M. Beman, B. Marshall, M. Corradini (Un Wisc.)

(Consultant: R. Anderson, ANL)

Objective: To perform designed experiments, conduct analyses, and develop or improve models for the phenomena governing corium-coolant interactions.

Budget Activity: 601930 FY 1986 PROGRAM: $585K FY 1986 Scope: THIS ORDER: $146K (10/1/85 - 9/30/86)

1. Conduct a set of designed experiments in the FITS vessel to investigate the effects of three independent variables on energy conversion ratio, hydrogen generation, steam generation, debris characteristics, quench rate, and the fraction of corium participating in the interaction.

A. The independent variables are: water depth, number of holes in a submerged stainless steel plate, and delayed trigger at time of corium stratification on the bottom of the water chamber.

(1) The two levels for water depth are: " low" is 29.7 inches; "high" is 52 inches. The depth of water is measured from the bottom of the water chamber to the top of the stainless steel plate with about 0.25 inches of water above the steel plate.

(2) The two levels for " number of holes" are: " low" is four (4) holes arranged in a " triangular" array, each 1.6 inches (4 cm) in diameter, with th(~ hole spacing center to center of 2.1 inches (5.3 cm); "high" is seven (7) holes arranged in a

" triangular" array, each 1.6 inches (4 cm) in diameter, with the hole spacing center to center of 2.1 inches (5.3 cm). These holes are in two different stainless steel plates each of which

, will represent a submerged lower grid forging in their respective tests.

(3) The two levels for delayed trigger are: " low" is no trigger; "high" is a delayed trigger. The trigger is to be fired af ter the corium is stratified in a pool on the bottom of the water chamber.

V Fin A1030 2 October 1, 1985 B. The fixed experimental conditions are:

(1) Corium mass is about 50 kg, to be verified in Item 2 below.

(2) Water temperature is saturation.

(3) System pressure is one atmosphere (1 bar).

(4) Rigid (wall and bottom) steel water chamber of a selected (fixed) diameter. This allows any explosions to expand in only one direction.

(5) Melt entry velocity is about 4 m/s.

C. The experimental matrix is given below.

Corium-Coolant Conversion Ratio Series Test Water Depth Number of Holes Delayed Trigger 1 52 in. 4 no 2 29.7 in. 7 no 3 29.7 in. 4 yes 4 52 in. 7 yes

2. Conduct one or two tests, not in the FITS vessel, to accurately and precisely measure energy conversion ratio under the same experimental conditions given in Iterr. I above, as preparation for the four tests described in item 1 above except that iron thermite melt may be used for these tests to reduce cost.
3. Conduct test 3D to cortplete the FITS D Series for 20 kg melts. Analyze these four test results for 20 kg melts to determine the effects of the other five independent variables.
4. During the second half of the fiscal year, conduct repeat tests from the FITS D Series.
5. As proposed in your 189a. the University of Wisconsin subcontract is acceptable. We estimate that the cost of this effort will not exceed $65K and that the scope will include:
a. Analyzing test results and comparisons to model or code predictions.
b. Corium-coolant interaction model or code predictions for

. experimental or full scale conditions,

c. Corium-coolant interaction model development or improvements,
d. Technical assistance on any aspect of corium-coolant interactions, as required.

6. Analyze the experimental conditions or approach of item 1, given above, for possible improvements; provide the written analysis to the NRC Technical Monitor before start of tests. All work, tests, and experiments not specified in this work brief, or changes in experimental conditions (e.g., as given in Items 1, 2, and 3) previously specified will be reviewed and approved in writing by the NRC Technical Monitor before start of work or testing.
7. Develop or adapt improved measurement systems for mixing, expansion, quench rate, energy conversion ratio, and related pressures for Items 1, 2, and 3 given above. Post test examination of debris will include characterization using scaning electron microscope pictures comparing edge vs. center for samples of debris particles. Candidate measurement devices include: impact plates, accelerometers, strain gages, and conductivity or temperature probes. Measurement system effectiveness will be demonstrated before start of experiments.
8. Provide technical consultation on specific topics related to corium-coolant interactions and make presentations, as requested by the NRC Technical Monitor.
9. Approximately six progress review meetings will be held during FY 1986,
10. Provide preliminary data reports on a timely basis (e.g., within 60 days) to the NRC Technical Monitor after completion of each test for work specified in Items 1, 2, 3, and 4 given above. -
11. Provide monthly reports itemizing project costs and progress by subtask activity and travel. Summarize project activities for the past month and identify any problems that might affect project milestones. This report will be submitted to the NRC Technical Monitor by the 10th of each month.
12. Provide a final draft report by September 30, 1986 for work Items 1 to 5 given above. The final draft report will contain a complete analysis of all test results for Item I given above (4 tests) and Item 3 given above (FITS D Series for 20 kg). For Items 1, 2, and 3, given above, a schedule is: complete the tests by April 1, 1986; complete post-test chemical, physical, and data analysis by June 1,1986; complete draft report and issue for comments by August 31, 1986.

, 13. Provide copies of any trip reports to the NRC Technical Monitor for trips which used project funds.
