ntegrated Impact 327, Editorial Revised so that this statement provides design overspeed determination criteria rather than simply requesting information. Also revised to clarify the existing criteria addressing reactor coolant piping breaks to reflect that breaks should be assumed consistent with the design basis for reactor coolant piping, so that pipe breaks need not be considered in any piping that has been acceptably analyzed to leak- before-break. This change incorporates PRB comments reflected in the September 21, 1995 Memorandum to R.W. Borchart from R. Hermann. 30. Editorial Removed extra word. 31. Reference Verification The latest version of Regulatory Guide 1.14 specifies inservice inspection in subsection C.4.b. 32. Incorporation of PRB Comment Added clarification regarding operating vs calendar years at the request of the PRB (see Memorandum to R.W. Borchart from R Hermann dated September 21, 1995). 33. SRP-UDP format item, develop Technical Rationale were developed and added for the Technical Rationales. Acceptance Criteria, GDC 1 and 10 CFR 50, §50.55a(a)(1) and GDC 4. Technical Rationale is a new SRP-UDP format item. 34. Integrated Impact 881 Revised list of materials suitable for fabrication of reactor coolant pump flywheels to include an additional grade of material. 35. SRP-UDP format item. Only the first citation of a reference will have a parenthetical notation. 36. Editorial Add information on the location of the material specifications listed in this paragraph. 37. Editorial Revised to incorporate PRB comment regarding grammar/structure (see Memorandum to R.W. Borchart from R. Hermann dated September 22, 1995). 38. Integrated Impact 330 Revised the terminology for fracture toughness to be consistent with current designations used in ASME code, section III, Appendix G. 39. Editorial Revised to incorporate PRB comment regarding grammar/structure (see Memorandum to R.W. Borchart from R. Hermann dated September 22, 1995). 40. Editorial Revised to
