Definition of data bases, codes, and technologies for cable life extension
The substantial number of cables inside containment for a typical nuclear facility provides a strong motivation to extend cable life rather than replace cables. Hence, it is important to understand what information is necessary to accomplish life extension. This paper defines utility-specific as well as collective industry actions that would facilitate extending cable life. The focus of these recommendations is (1) to more realistically define the environmental profiles during which cables must function, (2) to better understand the validity of accelerated aging methodology through examination of naturally aged cables, (3) to better understand the validity of accelerated aging methodology via selected experimentation, (4) to support cable aging analysis by improving nonproprietary data bases, (5) to reduce the impact of the design basis accident assumptions on cable performance so additional cable aging can be accommodated during extended life, and (6) to complement life predictions with more powerful cable condition monitoring techniques than those currently available.
