Return to operational states

Returning to an operational state is the final stage of any MS I activity, or of any other action involving temporary deviations from the normal operational state of a power plant. The return to an operational state should be carried out in accordance with appropriate operational procedures. 

Before returning to an operational state, it is important to ensure that  

Any necessary precautions and restraints on operation with temporary configurations or conditions should be clearly specified to all relevant personnel, and training should be carried out if necessary. 

Completion of any MS I activity should include a verification that all temporary connections, procedures and arrangements that were necessary for its implementation have been removed or cancelled and the plant has been returned to fully operational status. 

All safety related SSCs which were changed from their normal states should be returned to normal operational states. Their configuration should be verified by authorized personnel in accordance with prescribed procedures before the system is returned to operation. More information on the management of temporary configurations can be found in Ref. [4],
