t necessary to determine the general orientation and placement of main turbines. This can be done using general information normally provided in an FSAR. 35. Integrated Impact No. 230 Added the phrase "the containment and other" in the sentence to determine whether the turbine is favorably or unfavorably oriented. 36. Integrated Impact No. 230 Added text to define review responsibilities to determine favorable or unfavorable turbine orientation. 37. Integrated Impact No. 230 Deleted the review procedures that refer to mitigation of strike and damage probabilities from turbine missiles. The acceptance criteria was changed to allow standardized numbers for these quantities based on the general orientation of the turbine with respect to the containment and other safety-related equipment. Accordingly, review procedures related to strike and damage probability of turbine missiles are no longer needed. SRP Draft Section 3.5.1.3 Attachment A - Proposed Changes in Order of Occurrence Item Source Description 3.5.1.3-21 DRAFT Rev. 3 - April 1996 38. Integrated Impact No. 230 Added new item III.2 referring to review procedures to matching the acceptance criteria provided in subsection II of this SRP section. 39. Integrated Impact No. 230 Added new item III.3 to cover situations in which the applicant may propose to use barriers to mitigate or prevent damage from turbine missiles. 40. SRP-UDP format item Added standard paragraph to cover design certification reviews. 41. Integrated Impact No. 230 Deleted reference to calculations at the end of the sentence. The preparation of calculations to verify that barriers are competent will no longer be emphasized by the staff in its review of turbine missile hazards. 42. Integrated Impact No. 230 Deleted phrase that referred to the staff's review, in accordance with Regulatory Guide 1.115, for strike and damage probability. The staff's emphasis will now be focused on minimizing the probability of generation of turbine missiles. 43.
