Design and Construction Turnover cont'd

As discussed in program criterion 1.3.2.1.b, a technical management review should be performed to

determine the adequacy of the facility design requirements and design basis. Judgments of adequacy

should be based on completeness, accuracy, and full documentation. The conclusions and the basis

for the conclusions regarding the adequacy of the facility design requirements and design basis should

be documented in the facility CM program plan. If the conclusion is that the design requirements and

their design basis are not fully documented, not complete, or not accurate, then they should be

reconstituted to the extent called for by the design reconstitution adjunct program.

This technical management review should identify the actions necessary to evaluate the current status of

facility design requirements and design basis. It should consider the results of applicable assessments,

especially the initial CM assessments. The completeness and accuracy of the facility design

requirements and basis is one of the most significant areas to be evaluated during the initial

assessments. By correlating the design basis with the design requirements and the design requirements

with the physical configuration and facility documentation, the vertical slice assessment can provide

unique insights into the completeness and accuracy of existing design requirements and basis, as well

as into the effectiveness of past and present CM practices.

If the initial assessments support a definitive conclusion regarding the adequacy of the facility design

requirement and design basis, no further activities may be necessary other than a review of the

assessment results by technical management. However, if the initial assessments do not support a

definitive conclusion, the management review should identify additional actions to supplement the

findings of the initial assessments. The technical management review should include technical

managers having broad design backgrounds and experience and representing the various design

disciplines. Several different approaches to this review are possible. Whichever approach or

combination of approaches is chosen, it should focus on whether any design information is missing.

The technical management review process may include the following methods of assessing

completeness:

Comparisons with industry codes and standards that identify expected design information

Comparisons of like design requirements for comparable components

Comparisons of like design basis for comparable design requirements

Review of design information to identify SSCs with missing or incomplete information

Review of open items and discrepancies that have not been resolved

Review by independent, external, technical experts

In conjunction with the approaches listed above, a template approach may be used. A generic template

is prepared to identify the types of design requirements and design basis typical for a given SSC type.

The template is comprehensive and includes both the expected and possible design requirements and

design basis. The design requirements and design basis would be compared with the template to

identify missing requirements and design basis. For example, a template for piping might check for

design requirements such as basic flow diagrams, layout and arrangement diagrams, isometric

diagrams, support detail, material specification, testing requirements, and many other items. For the

design basis, the template for piping might check for pipe sizing/flow analysis, minimum wall thickness

evaluations, corrosion/erosion allowances, American Society of Mechanical Engineers (ASME) code

conformance, DOE commitments, system interface input requirements, design procedure

documentation, and many other items. Other examples of design requirement and design basis

information that could be appropriate for the templates are presented in Appendix IIB.
