Field Validation. For the design reconstitution program, the process of providing reasonable assurance

that design requirements are properly reflected in the physical configuration and in the associated

facility documentation. Field validation tests the strength of the basic CM relationships among the

design requirements, physical configuration, and facility documentation.

Formal Review. A process through which design information is identified and retrieved from on-hand,

top-level, summary-type design documents such as the Safety Analysis Reports, Technical Safety

Requirements, and System Design Descriptions.

Graded Approach. A process by which the level of analysis, documentation, and actions necessary to

comply with a requirement are made commensurate with a number of considerations, including the

relative importance to safety, safeguards, and security; the magnitude of any hazard involved; the

life cycle stage of a facility; the programmatic mission of a facility; the particular characteristics of a

facility; and any other relevant factor.

Horizontal Slice Assessment. An evaluation conducted on a program-by-program basis, such as change

control or document control, across various facility systems to determine the effectiveness of the

program or procedure. It compares existing program implementation against evaluation criteria,

performs an effectiveness review through field evaluations, identifies program strengths and

weaknesses, and develops recommendations for program improvement.

Life Extension. Actions specifically designed to reduce aging stresses or reduce the effects of aging

stresses for facility potentially life-limiting components, as might be necessary to achieve the desired

lifetime.

Lite-Limiting Component. A structure, system, and component whose failure could result in termination

of facility operations.

Material Condition & Aging Management. An adjunct program to the CM program that encompasses the

functions of: developing associated program plans and procedures; screening components to

determine those that are potentially life-limiting for the facility; evaluating, aging degradation

mechanisms; estimating the facility remaining lifetime; evaluating feasibility of continued operations

and extended operations; performing detailed material condition and aging analysis; and developing

necessary life extension techniques to achieve the facility desired lifetime defined by DOE.

Mission Design Requirements. Those design requirements that are necessary to prevent or mitigate

substantial interruptions of facility operation or severe cost impacts or are necessary to satisfy other

DOE mission considerations.

Monitoring. Continuous or periodic observation or measurement to verify that the performance or physical

characteristics of a structure, system, or component conform to acceptance criteria.

Non-reactor Nuclear Facility. Those activities or operations that involve radioactive and/or fissionable

materials in such form and quantity that a nuclear hazard potentially exists to the employees or the

general public. Included are activities or operations that: (1) Produce, process, or store radioactive

liquid or solid waste, fissionable materials, or tritium; (2) Conduct separations operations; (3)

Conduct irradiated materials inspection, fuel fabrication, decontamination, or recovery operations;

(4) Conduct fuel enrichment operations; or (5) Perform environmental remediation or waste

management activities involving radioactive materials. Incidental use and generating of radioactive

materials in a facility operation (e.g., check and calibration sources, use of radioactive sources in

research and experimental and analytical laboratory activities, electron microscopes, and X-ray

machines) would not ordinarily require the facility to be included in this definition. Accelerators and

reactors and their operations are not included. The application of any rule to a non-reactor nuclear

facility shall be applied using a graded approach.
