SPECIFIC ADMINISTRATIVE CONTROL
Relevant information is provided, in the following SAC specific subsections, for
SACs with descriptions sufficiently detailed to provide an understanding of the
safety function of the SAC. Descriptions for each SAC must be complete enough to
indicate suitability of safety analysis inputs and assumptions (see DOE-STD-1186).
Provide a summary list of SACs. This summary list should identify, in tabular form,
SACs, the accidents from Chapter 3 for which the SAC is a designated control,
safety functions, functional requirements, and performance criteria judged to require
TSR coverage. The remaining subsections provide details that correlate to the
Note: The following format is repeated seque ntially for each ("X") SAC. The
examples provided are for illustration purposes only, and should not be construed as
a requirement to designate such administrative controls as SACs.
4.5.X [Applicable Specific Administrative Controls]
Identify the SAC.
This subsection states the reason for designating an administrative control as a
SAC, followed by specific identification of its preventive or mitigative safety
function(s) as determined in the Chapter 3 hazard and accident analysis. Do
not discuss non-safety functions.
Safety functions are top level statements that express the objective of the SAC
in a given accident scenario. For example, the safety function of a Material at
Risk limit could be stated as: "To limit the total quantity of nuclear material
present within the facility to no more than 2000 Curies." The specific
accident(s) or general rationale associated with the safety function should be
This subsection provides a description of the SAC and the basic principles by
which it performs a safety function (e.g., nuclear material control procedure for
the MAR limit discussed in section 4.5.X.1). Describe its boundaries and
interface points with any SSCs relevant to the safety function, such as
procedural actions interfacing with sensors/instrumentation and equipment.
If a SAC is utilized in lieu of the identification of safety SSCs, clearly identify
and discuss the rationale for this decision. Engineering controls are preferable
over ACs and SACs, and emphasis should be placed on identifying safety
SSCs. Include a discussion regarding why SSC(s) are not plausible or practical
for accomplishing the safety function.
Identify SSCs whose failure would result in losing the ability to complete the
action required by the SAC. These SSCs would also be considered safety-class
or safety-significant based on the significance of the SAC safety function.
