CONTENT OF SYSTEM DESIGN DESCRIPTIONS

Outline of an SDD

CHAPTER 3

Requirements and Bases

3.1

General Requirements

SDDs shall adhere to the following outline to the

3.1.1 System Functional

extent that it is relevant to the system being

Requirements

described. When a section of the outline below is

3.1.2 Subsystem and Major

not applicable to the system, the section should be

Components

retained in the SDD with a simple statement that the

3.1.3 Boundaries and Interfaces

section is not applicable. It is preferred that a brief

3.1.4 Codes, Standards, and

explanation of its non-applicability also be provided,

Regulations

especially if the reason for the non-applicability

3.1.5 Operability

might not be immediately obvious to some readers.

3.2

Special Requirements

Conversely, the outline might need to be expanded

3.2.1 Radiation and Other Hazards

to address aspects of some systems not covered by

3.2.2 ALARA

the outline.

3.2.3 Nuclear Criticality Safety

3.2.4 Industrial Hazards

Note: The outline below is not

3.2.5 Operating Environment and

intended to define some minimum

Natural Phenomena

content requirement, but rather to

3.2.6 Human Interface Requirements

provide general guidance. This outline

3.2.7 Specific Commitments

is intentionally exhaustive to

3.3

Engineering Disciplinary

encompass important aspects of

Requirements

virtually any system. The content of

3.3.1 Civil and Structural

specific SDDs is expected to vary with

3.3.2 Mechanical and Materials

the type of physical system being

3.3.3 Chemical and Process

described (for example,

3.3.4 Electrical Power

ventilation/confinement systems,

3.3.5 Instrumentation and Control

electrical power systems, chemical

3.3.6 Computer Hardware and

processes).
