eference Updated the title for Regulatory Guide 1.68, “Initial Test Verification Programs for Water Cooled Nuclear Power Plants.” 168. Integrated Impact # 605 Added a reference to Regulatory Guide 1.155, “Station Blackout” to address staff guidance and positions on the station blackout event. 169. Integrated Impact # 600 Added a new reference for Regulatory Guide 1.157, "Best-Estimate Calculations of Emergency Core Cooling System Performance." 170. SRP-UDP Format Item, Editorial. Revised the clarification at the end of this reference to indicate that the Branch Technical Position RSB 6-1 is attached to this SRP Section. 171. Integrated Impact # 602 Added a reference to SECY 90-016 to support the Review Procedure added to address ECCS design configurations necessary to support inservice and functional testing. 172. Integrated Impact # 602 Added a reference to the SRM for SECY 90-016 to support the Review Procedure added to address ECCS design configurations necessary to support inservice and functional testing. 173. Integrated Impact # 602 Added a reference to SECY 93-087 to support the Review Procedures added to address the evolutionary BWR ADS general criteria and ECCS design configurations necessary to support inservice and functional testing. 174. Integrated Impact # 602 Added a reference to the SRM for SECY 93-087 to support the Review Procedure added to address the evolutionary BWR ADS general criteria and ECCS design configurations necessary to support inservice and functional testing. 175. Integrated Impact # 599 Added a reference to Generic Letter 83-02 which provides staff guidance on the minimum and maximum expected response times for the pipe-break-detection circuitry. This function ensures that pressure spikes resulting from HPCI and RCIC system initiation will not cause inadvertent system isolation. 176. Integrated Impact # 606 Added a reference to Generic Letter 88-17, “Loss of Decay Heat Removal” that contains guidance and staff positions
