SUBJECT: NOTICE OF VIOLATION (INSPECTION REPORT 05000263/2005003);

MONTICELLO NUCLEAR GENERATING PLANT

Dear Mr. Conway:

The NRC acknowledges the receipt of your letter dated October 24, 2005. In your letter, you

denied the revised Notice of Violation and documented your understanding that the partial

primary containment group II isolation actuation that occurred following a loss of Bus 16 on

April 2, 2005, was not a valid actuation as defined by NUREG-1022. Therefore, the actuation

was not reportable under 10 CFR 50.72(b)(3)(iv)(A). You concluded that the partial primary

containment group II isolation actuation was not the result of a valid signal because it was

caused by a loss of power to radiation monitors, following the loss of Bus 16, and not for the

radiation monitors sensing a high radiation signal. You also stated that the radiation monitors

response was not a valid safety system function because the loss of power response was not a

function specified in the Technical Specifications. Based on your analysis, you did not make an

8-hour report to the NRC Operations Center.

The NRC is currently reviewing your basis for disputing this violation in accordance with the

provisions in the Enforcement Policy. You will be advised by separate correspondence of the

results of our deliberations in this matter.

If you have any questions regarding this letter, please contact Mr. Bruce L. Burgess, Chief,

Reactor Projects Branch 2, at (630) 829-9629.

Sincerely,

/RA/

Mark A. Satorius, Director
