Subject:
Prairie Island - Units 1& 2- LAR - 3/25/04 - Main Steam Line Mass & Energy release using BAW-10169-A In reference to the above submittal, NRC staff has following questions which they would like to discuss with you. Please indicate your availability to have a teleconference with the staff.
- 1. Page 5. Explain the choice of 0.6 ft2 for the lower bound break size for the sensitivity study.
Are split breaks considered?
- 2. Verify that both cases with and without loss of offsite power will be considered to determine the limiting case.
- 3. Describe or provide a reference for the treatment of entrainment in the break flow. Was this included in the core response calculations?
- 4. Page 5. The statement is made that liquid inventory is maximized. But this corresponds to zero power. How is this consistent with sensitivity study to select limiting power?
- 5. Page 5. Why isnt a single failure of the auxiliary feedwater automatic run-out protection analyzed?
- 6. Page 5. Is the description of the modeling of the steam system consistent with the current licensing basis?
