Preparation and Issuance of Design Information Summaries

DOESTD107393

1.3.6.6 Preparation and Issuance of Design Information Summaries

Extracted design requirements should be entered into the CM equipment database promptly after

verification and technical validation. Design information summaries should include a system description

(including systems interface information), system operability requirements, system-level design

requirements, component-level design requirements, the design basis, and related design topical

information. They also should identify design requirements by type; attributes of the design that were

not mandatory for the designer should be distinguished from other types of design requirements. The

authorization basis should be clearly distinguished from other aspects of the design basis. The DISs

should be written for easy use by individuals at all levels of experience.

A DIS should be initially issued when the design requirements are complete and technically validated,

including the regeneration of missing critical design requirements. This Initial version should also

contain available technically validated design basis information and should identify open items to be

resolved. The DIS should be revised and reissued when the design basis has been reconstituted

(including regeneration of missing critical design basis) and the field validation has been completed.

The objective of the MCA adjunct program is to prevent the failure of facility life-limiting components

from aging degradation and the associated impact on facility operations. Aging degradation can so

impair the performance capability of equipment that it no longer meets its design requirements, and this

can compromise the CM program basic relationships.

1.3.7.1 Program Plans and Procedures

A program plan, an action plan, and implementing procedures should be developed for the MCA

adjunct program. The program plan should be based on the initial assessments and the graded

approach. The program plan should address the same topics identified for the CM program plan

(described in criterion 1.3.1.1.c).

1.3.7.2 Component Screening

Components in the facility, including passive components (e.g., structures), should be screened to

identify those that are potentially life-limiting for the facility.

1.3.7.3 Aging Degradation Evaluations

The remaining lifetime for each potentially life-limiting component should be evaluated. Major aging

degradation mechanisms that could affect potentially life-limiting components should be identified. The

present material condition of each such component should be determined.

1.3.7.4 Estimation of Facility Remaining Lifetime

The remaining lifetime of each potentially life-limiting component, with no life extension techniques

applied, should be estimated using engineering judgment. The facility remaining lifetime is the shortest

estimated remaining lifetime for a potentially life-limiting component.

1.3.7.5 Feasibility of Continued Operations and Extended Operations

If DOE has not specified a facility desired lifetime, the contractor should request that it do so. If not

specified, the desired lifetime should be taken to be the same as the remaining lifetime without the
