tion 5.4.7 Attachment A - Proposed Changes in Order of Occurrence Item Source Description DRAFT Rev. 4 - April 1996 5.4.7-46 168. Integrated Impact # 109 Added a reference to NUREG-1316 which provides technical findings and regulatory analysis related to the resolution of Generic Issue 70 “Power Operated Relief Valve and Block Valve Reliability.” 169. Integrated Impact # 105 Added a reference to NUREG-1449 which documents the staff’s evaluation of the shutdown and low-power issue. This reference supports the new Review Procedure developed to address RHR specific issues related to shutdown and low-power operations. 170. PRB Comment Added reference to NUREG-0927 in response to PRB comment, NRC Memo Li to Lyons dated November 1, 1995. 171. SRP-UDP Format Item, Editorial Added a parenthetical reference for the current PRB responsibility for BTP RSB 5-1. Reactor Systems Branch is currently responsible for this branch technical position. 172. SRP-UDP Format Item, Editorial. Changed "including" to "include" to make this sentence grammatically correct. 173. SRP-UDP format item, Metrication The cold shutdown condition, as described in the Policy Implementation Standard Technical Specifications, refers to a sub critical reactor with a reactor coolant temperature no greater than 200 F for a PWR and 212 F for a BWR. The temperature values were converted to Celsius in accordance with the metrication policy. 174. Integrated Impact # 109 Added a parenthetical statement to address the inclusion of instrumentation for monitoring and control functions consistent with the discussion on natural circulation cooldown contained in the FSER for the ABB-CE System 80+. 175. Integrated Impact # 108 Added a clarification to the Branch Technical Position on RHR system isolation valve interlocks. To improve overall reliability the NRC staff has recommended but not required that the autoclosure interlock be removed. The sentence was revised to eliminate the "shall" statement and to ensure
