C. Source for bases (justification) of TSRs

In the development of limits, set-points, staffing

requirements, and other parameters for input

into the individual TSRs, the facility/operation-

specific Safety Analysis Report (SAR),

particularly the accident analyses contained

therein, is normally the primary basis.

The limitations that are included in the TSRs

should be derived from the facility-specific safety

analysis, which considers all credible accidents.

This includes the most significant possible

releases of radioactive and hazardous materials,

criticality scenarios, and the accidental releases

expected during the life of the facility.

Careful and thorough examination of these

accident analyses will provide values for defining

the operational limits necessary to ensure that

facility operations do not occur outside the

bounds assumed in the analyses. Such an

examination will also identify parameters and

operating conditions that should be limited in

order to reduce, provide warning of, and mitigate

the uncontrolled releases of hazardous materials

and to prevent inadvertent criticality.

Examples of requirements expected to be

developed include:

Operating limits for principal process

parameters

Technical and administrative conditions that

must be met

Availability of safety equipment and systems

Critical functions of instrumentation and

controls
