- 1. General - Added revision numbers to PSAT cale references.
A
- 2. Item 1 - Added NUREG reference.
- 3. Item 2 - Finalized reference and removed exception (based on deletion ofItem 2.4, see 5 below).
- 4. Item 2.3 - Corrected typo in note and added clarification that "Other" could be included in dose calculation of record if contribution negligible.
- 5. Item 2.4 - Deleted because power purge is not being used to model Case 2 SGTS bypass.
- 6. Item 3.7 - Provided steamline/drainline volume and reference.
- 7. Item 3.8 - Changed MC volume to be slightly more conservative.
- 8. Item 3.20 - Finalized reference, changed value, and removed option for flow from torus (not needed because Case 2 SGTS bypass is being modeled using a specific flowpath from drywell - see 5 above).
- 9. Item 3.23 - Provided "two-step" drywell leakrates to steamline and clarified reference.
- 10. Items 3.24 and 3.25 - Provided values for steamline and MC volumetric flows and references.

- 11. Items 3.27 and 3.28 - Added " free" for clarification.
- 12. Item 3.29 - Added "per line" MSIV test limit.
- 14. Item 4.1 - Clarified " bid" spec.
- 15. Items 4.3 and 4.4 - Added clarification that values are medians over cited intervals.
- 16. Items 4.7 and 4.8 - Changed "DF" to " filter efficiency", provided values and references for Item j
4.7, and deleted item 4.8 because Item 4.7 particulate removal is so high that Item 4.8 not needed.
- 17. Item 5.1 - Made fumigation X/Qs 1.5 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> instead of 0 to 0.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.
- 18. Item 5.4 - Changed reference to TVA cale.
- 19. Items 7.3,7.4, and 7.5 - Added steamline ID, effective steamline length, and approximate containment dimensions.
- 20. Item 8.9 - Added use: steamline initial temperature determination.
- 21. Item 8.15 - Added site-specific " standard conditions" reference pressure for converting drywell to steamline volumetric flow.
