On June 6, 2013, the Nuclear Regulatory Commission (NRC) issued Order EA-13-1 09 (Reference 1) to Northern States Power Company, a Minnesota corporation (NSPM),
doing business as Xcel Energy. Reference 1 was effective immediately and directs NSPM to install a reliable hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris, for Monticello Nuclear Generating Plant (MNGP). Specific requirements are outlined in Attachment 2 of Reference 1.
Reference 1 required submission of a Phase 1 Overall Integrated Plan (OIP) pursuant to Section IV, Condition D. Reference 3 endorses industry guidance document, NEI 13-02, Revision 0 (Reference 4) with clarifications and exceptions identified in Reference 3. Reference 5 provided the MNGP Phase 1 OIP .
Reference 1 requires submission of a status report at six-month intervals following submittal of the Phase 1 OIP. References 2 and 4 provide direction regarding the
Document Control Desk Page 3 content of the status reports. References 6 and 7 provided the first and second six-month status reports for Phase 1 of the order.
In Reference 9, the NRC endorsed industry guidance document NEI 13-02, Revision 1 (Reference 8) with clarifications and exceptions identified in Reference 9. NEI 13-02, Revision 1 provides guidance for implementing Phase 2 of Order EA-13-1 09.
Reference 10 provided a combined Phase 1 and 2 OIP and provided an updated status of Phase 1 of the order.
The purpose of this letter is to provide the fourth six-month status report pursuant to Section IV, Condition D, of Reference 1, that delineates progress made in implementing the requirements of Reference 1. The enclosed report provides an update of milestone accomplishments, including any changes to the compliance method, schedule, or need for relief and the basis, if any.

L-MT-16-034 ENCLOSURE MONTICELLO NUCLEAR GENERATING PLANT FOURTH SIX-MONTH STATUS REPORT FOR THE IMPLEMENTATION OF NRC ORDER EA-13-1 09, "ORDER MODIFYING LICENSES WITH REGARD TO RELIABLE HARDENED CONTAINMENT VENTS CAPABLE OF OPERATION UNDER SEVERE ACCIDENT CONDITIONS, PHASES 1 AND 2" 1.0 Introduction Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, developed a Phase 1 Overall Integrated Plan (OIP) (Reference 1),
documenting the installation of a Hardened Containment Vent System (HCVS) that provides a reliable wetwell hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris for the Monticello Nuclear Generating Plant (MNGP), in response to Reference 2. Starting with this six month status report, updates of milestone accomplishments will be based on the combined Phase 1 and 2 OIP dated December 17, 2015 (Reference 9). Previous status reports for Phase 1 only were provided to the NRC in References 6 and 8.
NSPM developed an updated and combined Phase 1 and 2 OIP (Reference 9),
documenting:
- 1. The installation of a HCVS that provides a reliable hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris, in response to Reference 2.
- 2. An alternative venting strategy that makes it unlikely that a drywell vent is needed to protect the containment from overpressure related failure under severe accident conditions, including those that involve a breach of the reactor vessel by molten core debris, in response to Reference 2.
This enclosure provides an update of milestone accomplishments since submittal of the combined Phase 1 and 2 OIP, including any changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any.
2.0 Milestone Accomplishments None.

L-MT-16-034 3.0 Milestone Schedule Status The following provides an update to Part 5 of the combined Phase 1 and 2 OIP (Reference 9). It provides the activity status of each item, and whether the expected completion date has changed . The dates are planning dates subject to change as design and implementation details are developed (i.e., not considered formal regulatory commitments). This schedule is current as of May 31, 2016.
One Milestone activity is being revised in this report. The Phase 1 Design Engineering On-site/Complete milestone target completion date is being revised from June 2016 to July 2016. A potential change to the scope of the design modifications was recently proposed that may impact the revised milestone date. If the additional scope impacts the milestone date, then additional information will be provided to the NRC in a future 6-month update.
The revised milestone target completion date does not impact the order implementation date.
