ted Impact 223. Added generic text referring to the applicable acceptance criteria to ensure that thermal-hydraulic stability is considered for all appropriate operating conditions. The generic nature of the text allows application of the review procedure to both PWRs and BWRs. 57. Integrated Impacts 220 and 221. Added a paragraph for the reviewer to evaluate the thermal-hydraulic stability of BWR applicants. The paragraph provides a lead-in to specific items to be reviewed. 58. Integrated Impact 220. Added guidance to Review Procedures for long-term resolution of thermal-hydraulic concerns by incorporating the long term required actions from Generic Letter 94-02. 59. Integrated Impact 221. Added guidance to Review Procedures for resolution of thermal-hydraulic stability during ATWS events by reference to Topical Reports NEDO-32047 and - 32164. 60. Integrated Impact 224. Added guidance to Review Procedures for (N-1) loop operation by incorporating information from Generic Letter 86-09. Similar information from the ABWR FSER were provided for inoperable Reactor Internal Pumps (RIPs). 61. GSI B-3 Resolution Corrected "anticipated transients" to be "anticipated operational occurrences." 62. Current PRB names and Editorial change to reflect the current PRB name and abbreviations responsibility for SRP Section 4.4. 63. Current PRB names and Editorial change to delete the text stating the CPB will abbreviations provide consultation to the RSB. The responsibilities of the previous CPB and RSB are combined under the current SRXB. 64. GSI B-3 Resolution Corrected "postulated accident" to "design-basis accident." 65. Current PRB names and Editorial change to add "The" to the beginning of the abbreviations sentence and to update the abbreviation for the Mechanical Engineering Branch from "MEB" to "EMEB." 66. GSI B-3 Resolution Added "design-basis" prior to the word accident. 67. Current PRB names and Editorial change to reflect the current PRB name and abbreviations
