A Duke Energy Company Scoping and Screening a Activities associated with plant components are divided along discipline function lines throughout the.

Integrated Plant Assessment a Rule of Thumb:

The discipline boundaries, with few exceptions, are as follows: if a component or parts of it carry electrical current, it is Electrical; if it supports, protects or restrains the movement of a component, it is Structural; everything else is Mechanical. Exceptions to this are noted where applicable.

m This orientation will lead us through each of the discipline approaches to scoping and screening to determine the structure and component set (C)

April 21, 1999 6

A Du er Scoping and Screening A4 Duke Energy Complay

  • Keys to each discipline to keep in mind:

Structural - relies on Oconee CLB definition to establish scope Mechanical - works through a functional review process to include plant components in scope Electrical - relies on an encompassing approach to include all plant electrical components in scope unless they are specifically scoped out or screened out April 21, 1999 7

A Duke Energy Company a Structures are classified according to their design function and relationship to public safety in the Oconee UFSAR.

  • Class 1 structures prevent uncontrol ed re ease of radioactivity and are 'designed to withstand all loadings without loss of function.

m Class 2 structures are those which do not perform a nuclear safety function but their failure could reduce the function of a nuclear safety system to an unacceptable level.

Component Screening A Duke Energy Company POCeSS m Consistent with guidance provided in NEI 95-10 Rev. 0, components subject to aging management review are those that are "passive" and "long-lived."

mA menu of every mechanical component commodity type installed in the plant was developed, going beyond the list of components in NEI 95-10.

M Using the "passive" and "long-lived" guidance, a determination was made for each of those mechanical component types.

Component Screening A Duke Energy Company Process m The components within the evaluation boundaries shown on the license renewal flow diagrams were "driven" through the menu to determine if they are subject to aging management review.

  • From this exercise, a list of components subject to aging management review was developed.
