on and responsibility for SRP Section 6.2.3. 40. Integrated Impact 384 Added a review procedure for new applications verifying that analyses of the ability to draw a negative pressure on the secondary containment volume following a LOCA assume that all lines that do not receive an isolation signal are open and that the worst- case secondary containment isolation valve fails to close. 41. Current PRB names and Editorial change made to reflect the current PRB abbreviations abbreviation and responsibility for SRP Section 6.2.3. 42. SRP-UDP format item. Format change to make the citation of references consistent with the SRP-UDP format guidance. Also updated the reference numbers to reflect added reference for the CONTEMPT-LT28 computer code. 43. No change proposed, Potential Several updated versions of CONTEMPT4 were Impact 24449, Reference Verification identified from NUREG-0933 Issue B-15, "CONTEMPT Computer Code Maintenance" references and from SRP-UDP Recall index of NUREG Abstracts. It could not be determined with certainty that CONTEMPT-LT code limitations discussed have been resolved. Note that in the ABWR FSER, Section 6.2.1.2, it is indicated that the staff performed independent confirmatory analyses with the CONTEMPT-LT28 computer code (See Potential Impact 24449). No discussion of CONTEMPT-LT28 computer code limitations for calculating long-term containment responses were discussed in conjunction with the above. If the current version of the CONTEMPT-LT code is not subject to the limitations discussed, consideration should be given to deleting discussion of these limitations.
