Significance Colors in the SDP

• GREEN (Licensee Response Band )

• Cornerstone objectives fully met. Nominal risk with nominal deviation from expected performance.

• Cornerstone objectives met with minimal reduction in safety margin. Changes in performance consistent with CDF<10-5 (LERF<10-6).

• YELLOW (Required Regulatory Response Band )

• Cornerstone objectives met with significant reduction in safety margin. Changes in performance consistent with CDF<10-4 (LERF<10-5).

• RED (Extensive Regulatory Response Band )

• Performance within the cornerstone represents an unacceptable loss of safety margin. Changes in performance consistent with CDF>10-4 (LERF >10-5). Sufficient safety margin still exists to prevent undue risk to public health and safety.
