On March 12, 2012, the NRC staff issued Order EA-12-050, "Issuance of Order to Modify Licenses with Regard to Reliable Hardened Containment Vents," (Reference 1) to all NRC power reactor licensees and holders of construction permits in active or deferred status. The NRC Order was immediately effective and directs Northern States Power Company (NSPM), a Minnesota corporation, d/b/a Xcel Energy, to have a reliable hardened vent (RHV) to remove decay heat and maintain control of containment pressure within acceptable limits following events that result in the loss of active containment heat removal capability or prolonged station blackout (SBO) for Monticello Nuclear Generating Plant (MNGP). Specific requirements are outlined in Attachment 2 of Reference 1.

Document Control Desk Page 2 Reference 1 requires submission of an initial status report 60 days following issuance of the final interim staff guidance. The final Interim Staff Guidance (ISG) JLD-ISG-2012-02, Revision 0, "Compliance with Order EA-12-050, Reliable Hardened Containment Vents," (Reference 2) was issued August 30, 2012. The purpose of this letter is to provide the initial status report pursuant to Section IV, Condition C.2, of Reference 1 within 60 days following issuance of Reference 2. This report confirms NSPM has received Reference 2 and is in the process of evaluating the guidance for the purpose of having a RHV to remove decay heat and maintain control of containment pressure within acceptable limits following events that result in the loss of active containment heat removal capability or prolonged SBO as described in Attachment 2 of Reference 1.

NSPM has installed a Hard Pipe Vent System from the wetwell vapor space in response to NRC Generic Letter 89-16, "Installation of Hardened Wetwell Vent," dated September 1, 1989 (Accession No. ML031140220).

Section 4.0 of Reference 2 contains the specific reporting requirements for the initial status report. The following information provides the status pursuant to Section 4.0 of Reference 2.

Major activities completed during this reporting period:

Resources are being identified and project plans initiated, including development of milestones, to assure compliance with Reference 1.

Planned activities for the next six months:

Technical difficulties encountered that could affect the ability to provide the licensee's February 28, 2013, submittal:

None at this time.

Project milestones schedule through completion of installation and testing:

A project milestones schedule will be provided with the overall integrated plan.

Implementation of the order will be completed for MNGP prior to startup from Refueling Outage (RFO) R27 (Spring 2015).
