Safety Related Design Standards and Criteria

DOE-HDBK-6004-99

2. Display parameter values necessary for operator response to off normal systems operating

parameters or transient conditions.

3. Operate permissive or interlock functions designed to prevent facility systems from:

a) entering into off normal operating parameter or transient conditions, or

b) allowing an existing transient condition to continue its off normal excursion.

4. Operate automatically to:

a) respond to off normal or accident conditions,

b) move the facility toward or attain a safe operational state, or

c) mitigate the consequences of the off normal or accident conditions.

5. Enable operator manual initiation of safety related control actions or bypasses.

6. Detect and indicate parameters necessary to ensure the integrity of designated defense in depth

barriers. These parameters may include but are not limited to:

a) indicators of radioactive, toxic, or other material leakage or migration to detect breach

of a barrier,

b) temperature conditions indicative of trends toward undesired material conditions (e.g.,

nil ductility considerations or high-temperature loss of strength),

c) over or under pressurization detection for facility systems, or

d) chemical or gas mixture potential flammability or deflagration detection.

7. Monitor safety barriers and provide for response or mitigation action designed to prevent the

breach of a barrier or to control the effect of barrier breach.

8. Post accident monitoring or control functions necessary for indication, data logging or required

continued systems operations.

9. Measure, display, and alarm conditions approaching or exceeding parameter limits defined by

Technical Specification Requirements or Technical Standards.

Safety Related Design Standards and Criteria

The following listed standards and criteria provide a cohesive philosophy and set of principles

appropriate for application to the analysis and design of I&C Systems and components for fusion

devices. The concepts and principles contained in these documents, including referenced standards,

should be applied, using the necessary adjustments required to account for any specific fusion

technology special considerations.
