chment A - Proposed Changes in Order of Occurrence Item Source Description DRAFT Rev. 3 - April 1996 3.5.1.3-18 15. Editorial modification Deleted "instrumentation and." Instrumentation is reviewed by HICB, and the review responsibilities are explained in new text added at the end of the paragraph. 16. Editorial modification Changed "its" to "their" to reflect the reference to two branches. 17. Current review branch responsibility Added "The Instrumentation and Control Systems Branch (HICB), in cooperation with the EMEB and SPLB, reviews seismic and environmental qualification of instrumentation as part of its secondary review branch responsibilities for SRP Sections 3.10 and 3.11." This change reflects current secondary review branch responsibilities. 18. Current review branch responsibility Changed review interface branch to SPLB. 19. Editorial modification Deleted "primary." Secondary review branch responsibilities are described in the subsection, so the word no longer applies. 20. Editorial modification Deleted redundant phrase "section of the corresponding primary branch" and replaced it with the word "sections." 21. Integrated Impact No. 230 Deleted obsolete acceptance criteria. The staff's emphasis focuses on lowering the probability for generating turbine missiles rather than mitigating their effects. Accordingly, the obsolete text was deleted. 22. Integrated Impact No. 230 Added items 1 and 2, which describe acceptance criteria that are in accordance with the staff's current position, as outlined in a number of documents. This text was adapted from Supplement 3 to NUREG-0887 (Perry SSER) and reflects the staff's emphasis on preventing turbine missile generation. Similar text can be found in Appendix U to Supplement 6 of NUREG- 1048 (Hope Creek SSER). The Hope Creek SSER is cited in subsection 3.5.1.3 of the CE80+ FSER, NUREG-1462. Item 1 describes the regulatory bases for protecting equipment from turbine missiles. Item 2 describes the calculation of damage
