Q

What are the Adherence Principles for Procedure Use?

A

1) Where there is a procedure that covers a specific activity, the approved procedure shall be used.
2) Understand the purpose, scope, and intent of the procedure.
3) Review the procedure before use to identify adherence issues. Resolve the issues prior to performing the task.
4) Follow the procedure in order unless specific direction is given to deviate.
5) If the procedure cannot be used as written place work in a safe condition and resolve the issue.
6) Activities plant configuration activities not covered by a technical procedure:
A. Qualified plant personnel are required to take appropriate actions to place the plant in a safe condition, Independent of procedures.
B. Configuration control is maintained by admin procedure, clearance, WO, etc until the condition is restored.
7) Departure from Tech Specs is accomplished using 10CFR50.54(x). This departure is made by an SRO.
