Performance data shall be collected and recorded either continuously or at

19、specifi ed intervals throughout the test duration. If data are not continuously mon-itored, the sampling intervals must be suffi cient to demonstrate compliance with the performance criteria. Performance criteria, such as current, insulation resistance, and impedance, shall be pertinent to the sampl

A basis for the post-DBE duration shall be established, recognizing that compression of that period may need to be accomplished for practical purposes. An approach such as the evaluation

23、of equipment that must remain operable in the long term, including the use of alternative means to maintain the reactor in safe condition, may provide a suitable basis for compression of the post-DBE duration.6.5.4.2 Post-design-basis event simulation testUpon completion of the DBE simulation, to de

25、ap water at room temperature for a period of one hour. While still immersed, the specimens shall pass the voltage withstand test specifi ed in 6.5.2 item d). Some specialty cables, such as certain coaxial or triaxial cables, are selected for their added insulation. In these instances, margin may be

26、demonstrated at lower withstand test voltages. If the test voltage selected is other than the test voltage specifi ed in 6.5.2 item d), the voltage shall not be less than twice rated plus 1000 V.6.5.5 Retained fl exibilityTo demonstrate the retention of a degree of fl exibility, a sample of the cabl

Qualifi cation for normal and mild eventsCables and splices located in normal and mild environments shall be specifi ed, designed, and selected to per-form in their intende

28、d service conditions. This includes evaluating thermal and radiation data to establish the service life. A qualifi ed life is not required for cables and splices located in a mild environment. Qualifi cation for cables and splices located in mild environments shall be demonstrated by providing certi

29、fi ed evidence that the cables meet or exceed the specifi ed requirements, including those of recognized industry associations and 6.5.2. For the purposes of this standard, recognized industry associations are the Association of Edison Illumi-nating Companies and the National Electrical Manufacturer
