Definition of data base, code, 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 as part of an overall plant life extension strategy. 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 define plant configuration and operational changes which may enahnce cable life, (3) to better understand the validity of accelerated aging methodology through examination of naturally aged cables, (4) to better understand the validity of accelerated aging methodology via selected experimentation, (5) to support cable aging analysis by improving nonproprietary data bases, (6) to reduce the impact of the design basis accident assumptions on cable performance so additional cable aging can be accommodated during extended life, and (7) to complement life predictions with more effective cable condition monitoring techniques than those currently available.
