Subject:

Shutdown Margin Calculation Mr. Lee, What did the OIG decide regarding whether or not, as Region IVclaims, Callaway Plant had performed a Shutdown Margin Calculation on October 21, 2003 prior to tripping the turbine and relying on Xenon-135 to maintain the reactor subcritical for 106 minutes? Did the OIG decide to look into it? Will anyone ever be following up with me?

Thanks, Larry From: Criscione, Lawrence Sent: Wednesday, February 02, 2011 1:27 PM To: Lee, David
