tion capability. Events involving such failures and the potential common-mode failure mechanisms involved are described in Information Notices 82-19, 83-77, 86-63, and 87-57. 41. Current PRB names and Editorial change made to reflect the current PRB abbreviations abbreviation for SRP Section 15.4.6. 42. Current PRB names and Editorial change made to reflect the current PRB abbreviations abbreviation for SRP Section 15.4.6. SRP Draft Section 15.4.6 Attachment A - Proposed Changes in Order of Occurrence Item Source Description DRAFT Rev. 2 - April 1996 15.4.6-14 43. Current PRB names and Editorial change made to reflect the current PRB abbreviations abbreviation for SRP Section 15.4.6. 44. Editorial Revised to reflect that SRXB is the current PRB for SRP section 4.2. 45. Editorial Eliminated unnecessary gender specific pronoun. 46. Current PRB names and Editorial change made to reflect the current PRB abbreviations abbreviation for the Instrumentation & Controls Branch. 47. Editorial Revised to use previously defined DNBR abbreviation for departure from nucleate boiling ratio. 48. No change proposed, See Potential Although NRC Information Notices generally do not Impacts 24590 and 24592 provide sufficient basis for SRP changes under the SRP-UDP, SRXB may wish to emphasize consideration of the conservatisms necessary for reliable use of flux measurement/flux ratio increases as an indication of boron dilution. Information Notice 91- 54 describes new event sequences identified by NRC based upon foreign studies of boron dilution events. Information Notice 93-32 describes nonconservative inputs for boron dilution event analysis of Westinghouse boron dilution mitigation systems. 49. SRP-UDP Guidance, Implementation Added standard paragraph to address application of of 10 CFR 52 Review Procedures in design certification reviews. 50. Editorial Eliminated use of a gender specific pronoun. 51. Editorial Revised for consistency with previously defined DNBR abbreviation for
