EXTERNAL - STOP & THINK before opening links and attachments.
All,
I am  looking for insight on the way that each of your stations post your drywell during refueling outages and online.


  *   During operating periods, how do you post your Drywell interlock door? LHRA, Grave Danger or other?
  *   During refueling outages, do you control your Drywell as a LHRA or based on conditions can you down post it to HRA?



At NMP, we post the Drywell Airlocks VHRA/Grave Danger during online, and down post to LHRA during refuel periods.
