CFR Title: 

Content:
piping systems must be arranged so that the differential pressure between the sump and the RWST (or BWST), even if there is a single active failure, will not result in a loss of core cooling or a path that permits release of radioactive material from the containment to the environment. 3. Implementation A. Applicants for a construction permit for which an SER was published prior to April 16, 1975 will not be required to comply with the provisions of this item. B. For plants with an operating license issued prior to July 1981 and operating license applications docketed prior to July 1981 the position will not be completely applied. Specifically, locking out power to valves will be permitted. For most plants it is expected that this will be sufficient to meet the single failure criteria. However, in other plants changes to the piping and valving arrangements may be required to satisfy the single failure criteria. BTP 6-5-3 Revision 3 - March 2007 C. Applications docketed on or after July 1981 will be reviewed according to the provisions of this item.
