Fully Developed Element

2.2.3 FULLY DEVELOPED ELEMENT

A schematic for the fully developed design requirements element and its program interfaces is

presented as Figure 29. The design process can be initiated through change control processes that

involve requests for a wide range of engineering design support - from major permanent facility physical

changes to engineering evaluations for adjusting operations setpoints or revising maintenance and

testing requirements. Requests for engineering design typically include a description of the problem and

sometimes include a requested or proposed facility change. This information contributes to the design

inputs for the design process.

After the design process establishes new or revised design requirements and their basis, the approved

design requirements are processed through the change control processes necessary to authorize,

implement, test, and document physical changes in the facility or changes in facility documentation.

When a design change affects neither the physical configuration of the facility nor facility

documentation, the approved design output documents may go directly to the document control

program element for a records update and distribution as appropriate. An example of this type of

design change would be a design reanalysis that discloses the need for a reduction in heat exchange

capacity from 88 to 80 percent. Design basis documentation may also be forwarded to document

control for storage and future retrieval. Revisions to the design requirements that affect the

assessments element should provide appropriate review and for execution of the various assessments

element functions. For example, a design change might specify in-service testing or post-modification

testing requirements. Additionally, design requirements might specify periodic monitoring criteria and

methods.

2.2.4 SPECIFIC APPLICATION OF GRADED APPROACH: DESIGN REQUIREMENTS ELEMENT

With respect to the establishment of the design requirements and design basis, a distinction is made

between new work and reconstitution. Design requirements and design basis should be developed for

new design work. For the reconstitution process of retrieving and regenerating existing design

requirements and design basis, these functions should be adjusted according to a graded approach, as

described in Chapter 3.

2.3 DOCUMENT CONTROL ELEMENT

Development of the document control element is discussed below in two stages: the initial

development activities and the fully developed program element. The initial development activities

include those actions necessary to identify and evaluate the existing population of documents and

document processes. The fully developed program element comprises the activities involved in

ongoing, steady-state document control.

2.3.1 INITIAL DEVELOPMENT ACTIVITIES

Initial development of the document control element is depicted in Figure 210.

2.3.1.1 Identification of Documents To Be Included In CM Program

Early in CM program development, a determination should be made as to which documents will be

included. The steps necessary to accomplish this are as follows:
