Pursuant to 10 CFR 50.46(a)(3)(ii), the Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, is providing this annual report concerning changes/errors identified in the Emergency Core Cooling System (ECCS) evaluation models for the Monticello Nuclear Generating Plant (MNGP). The MNGP Loss of Coolant Accident (LOCA) analyses of record (AOR) are contained in the General Electric Hitachi (GEH) reports submitted for the MNGP Extended Power Up rate and the Maximum Extended Load Line Limit Analysis Plus (MELLLA+) license amendments (Reference 1 and 2).
A 30-day report was completed in June 2014 due to the issuance of several GEH Nuclear Energy 10 CFR 50.46 Notification Letters (Reference 3). The changes/errors discussed within those notification letters resulted in a cumulative increase in Peak Cladding Temperature (PCT) that exceeds the 50°F reporting threshold of 10 CFR 50.46(a)(3)(i), and hence, were reported in accordance with the regulation. There are
Document Control Desk L-MT-14-101 Page 2 of 2 no new notifications of changes or errors from GEH since submittal of the 30-day report sent in June of 2014. The nature of these changes/errors and their effect on PCT is summarized in Table 1 of Enclosure 1. These changes result in an adjusted PCT increase from the previously reported 2150°F (Reference 4) to 2170°F.
As prescribed by the regulation a proposed reanalysis schedule or an evaluation is needed to demonstrate the facility remains in compliance with 10 CFR 50.46 requirements. In accordance with 10 CFR 50.46(a)(3)(ii) the following evaluation is provided. The adjusted PCT is 30°F below the 2200°F acceptance criterion of 10 CFR 50.46(b)(1 ). This provides sufficient margin to justify taking no further actions. No further reanalysis or other actions are planned. provided additional information on the nature of the changes and their effect on the MNGP LOCA analysis. This information is being submitted in accordance with the requirement of 10 CFR 50.46(a)(3)(ii) for the MNGP.
If you have any question regarding this request, please contact Mr. Stephen Sollom at (763) 295-1611.

GE14 NEDC-33322P, Revision 3, Safety Analysis Report for Monticello 1 &2 <2140 Constant Pressure Power Uprate PRIME Fuel Properties Implementation for Fuel Rod T/M Performance, replacing GESTR Fuel Properties (1 0 CFR 50.46 Notification Letter 2012-01, Revision 1)
This change is due to the application of an NRC-approved 3 +10 procedure to estimate the change in Peak Clad Temperature (PCT) due to the change in fuel properties from GESTR to PRIME primarily to address inaccuracies in fuel pellet thermal conductivity as a function of exposure.
SAFER04A E4-Maintenance Update Changes (1 0 CFR 50.46 Notification Letter 2014-01)
This change is for a new version (E4) of SAFER04A that 4 +0 resolves several accumulated observations that are code maintenance items. Sensitivity calculations show these items have an insignificant effect on calculated PCT.
SAFER04A E4-Mass Non-Conservatism (1 0 CFR 50.46 Notification Letter 2014-02)
This change is due to a logic error that occurs when upper plenum liquid mass and core spray flow rate are low. System 5 +15 mass is gradually lost due to core spray being discarded, resulting in marginally less ECCS flow credited as reaching the core.
SAFER04A E4-Minimum Core DP Model (1 0 CFR 50.46 Notification Letter 2014-03)
This change is due to the use of a minimum ~P that could be 6 +20 non-conservative offering inappropriate steam cooling benefit above the core two-phase level.

GE14 SAFER04A E4-Bundle/Lower Plenum CCFL Head (1 0 CFR 50.46 Notification Letter 2014-04)
This change is due to the counter current flow limitation (CCFL) 7 -15 calculation representing the pressure head slightly different from that of the calculated water level in the bundle.
