ENCLOSURE 1
'l
QUESTIONS FOR JUNE 10, 1993 MEETING ON CONDENSATION TESTS FOR THE SIMPLIFIED BOILING WATER REACTOR (SBWR) 1.
How will the data base be used in the overall validation process? Will it be restricted to the passive containment cooling system (PCCS) containment condenser or will it be also used for the isolation condenser (IC)? If it is intended to apply to all condensers, identify those tests that are intended to apply to the IC.
2.
It appears to the staff that this is the only testing program at the University of California at Berkeley (UCB) related to the SBWR and that condensation testing related to the SBWR at the Massachusetts Institute of Technology (MIT) is complete. Are there any other programs either completed or under way at UCB or any other university, such as MIT, that will be used in the validation program of the SBWR7 3.
Provide a complete test matrix for all program phases.
Parameters for each test should include, as a minimum, the following information:
Supply conditions such as pressure, temperature, and flow rate.
Concentrations of steam and noncondensible gases throughout the test apparatus.
Exhaust conditions such as pressure, temperature, and flow rate.
4.
Provide a discussion of any preliminary results and conclusions reached.
5.
Discuss the schedule and type of reports that are planned to document the testing results.
6.
Provide e discussion of how this testing program represents the actual conditions of the SBWR, and a corresponding discussion of how the program differs.
In particular, the staff is interested in the degree of inlet /
exit plenum simulation, a., well as how the test hardware configuration simulates (or fails to simulate) the actual SBWR design.
7.
Provide a discussion on the repeatability of results and whether or not an error analysis has been incorporated into the results.
8.
There have been earlier discussions concerning whether vibration is a significant load for the intended range of operating conditions, in particular, the relationship between concentration of noncondensible gases and vibratory loading. How is vibratory loading in the tests being simulated?
)
i QUESTIONS FOR JUNE 10, 1993 MEETING, continued 9.
Provide a discussion of the preliminary findings of reaching steady state operation.
In other words, does the process appear to be rapid and j
consistent or do there appear to be oscillatory instabilities.

- 10. GE Nuclear Energy's draft supplement to the SBWR standard safety analysis report was submitted to the staff on May 7, 1993.
Nine references are listed in this supplement which relate to the University Condensation Tests at UCB and MIT. Are there any other reports which are related to these tests which have not been submitted? Please provide copies of the j
folloiting references listed in the supplement which the staff has not yet received:
