Safety Envelope Verification

DOE-STD-3006-2000

SAFETY ENVELOPE VERIFICATION (SE)

OBJECTIVE

SE.1 Facility safety documentation is in place that describes the "safety envelope" of the facility. The

safety documentation should characterize the hazards/risks associated with the facility and should identify

mitigating measures (systems, procedures, administrative controls, etc.) that protect workers and the

public from those hazards/risks. A system to maintain control over the design and modification of

facilities and safety-related systems is established. (CORE REQUIREMENT 7)

Criterion

The safety documentation addresses appropriate hazards/risks associated with operations.

Administrative controls are in place to ensure that repairs (or modifications) are adequately

analyzed to identify and to ensure that design changes are documented and approved prior to

implementation. (5480.23, para 8, Attachment 1, section 3 and 4, DOE-STD-1073-93, Ch.1.3,

S/RID FAs 03 and 08)

Approach

Record Review: Review safety basis documentation to assess whether the safety basis adequately

includes appropriate hazards/risks associated with XXX operations. Review recent design

changes and modifications to the facility to ensure that they have been reflected in drawings and

documents available to operators and maintenance personnel.

Interviews: Interview personnel associated with developing/processing facility modifications to

determine if they understand configuration management requirements for the facility.

Shift Performance: Perform a facility walk down to determine that there are no uncontrolled

modifications to safety systems. This walk down should evaluate the accuracy of drawings and

other documentation for plant operation and maintenance. At least one recently completed

modification should be observed and changes verified, including changes to operating procedures

if applicable.
