bypass and inoperable status indication. 49. Editorial, SRP-UDP format item Deleted title and added identification of IEEE 279 by reference number for the first citation of this non- CFR/RG reference citation. 50. SRP-UDP format item Revised to discuss why BTP-21 is relevant to this branch position and therefore listed as reference 4. SRP Draft Section recommendations Attachment A - Proposed Changes in Order of Occurrence Item Source Description 8A-25 DRAFT Rev. 3 - April 1996 51. Integrated Impact 1532, Reference Updated reference to where a diesel generator unit is verification defined noting that RG 1.108 which was withdrawn with the issuance of RG 1.9, Rev. 3. 52. Integrated Impact 1532 Added listing of features that are part of a diesel generator unit as reflected in RG 1.9 and IEEE Std 387-1984. 53. SRP-UDP format item Added citation of the IE Circular listed as reference 5. 54. Integrated Impact 1532, Editorial Revised to reflect that bypass/inop conditions that Global Change throughout this BTP might not prevent starting the engine but that could cause subsequent failure to achieve/maintain proper speed, failure to connect to the bus, failure to sequence loads, and/or failure to supply adequate power to the Class 1E bus should also be considered. It should be noted that Regulatory Guide 1.9, Rev 3 reliability and testing program guidance reflects evaluation of diesel-generator performance and operability in terms of the overall demand, not just the ability to start the engine. 55. Editorial Moved (from position 1) the list of examples of inop/bypass conditions to the background section because the list may have been incomplete and therefore misleading when provided in conjunction with a position addressing inop/bypass indication. The list could have been interpreted to constitute a default minimum acceptable compliment of inputs to inop/bypass indication for a diesel-generator when provided as it was in conjunction with a position. Items such as autostart
