Docket No. 50-263 Renewed Facility Operating License No. DPR-22 2017 Annual Report of Changes in Emergency Core Cooling System Evaluation Models Pursuant to 10 CFR 50.46
References:
- 1) Letter from P. Gardner (NSPM) to NRC, "2016 Annual Report of Changes in Emergency Core Cooling System Evaluation Models Pursuant to 10 CFR 50.46," (L-MT-16-071), dated December 19, 2016
- 2) Letter from P. Gardner (NSPM) to NRC, "June 2017, Thirty-Day Report of Changes in Emergency Core Cooling System Evaluation Models Pursuant to 10 CFR 50.46," (L-MT-17-045), dat-ed June 22, 2017 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 or errors identified in the Emergency Core Cooling System (ECCS) evaluation models for the Monticello Nuclear Generating Plant (MNGP).
Provided within Enclosure 1 is a report concerning any changes or errors identified in the AREVA ECCS evaluation models for MNGP. This report is for the period between July 2016 and July 2017 for the ATRIUM 10XM fuel. During this period there was a notification of changes or errors resulting in a change to the calculated Peak Clad Temperature (PCT) of 51 oF and therefore reported in a 30-day report (Reference 2).
There have been no additional changes since that report. The previously report PCT of 2085oF for the ATRIUM 1OXM fuel since the 30-day report is unchanged.
Provided within Enclosure 2 is a report concerning any changes or errors identified in the General Electric-Hitachi (GEH) ECCS evaluation models for MNGP. This report is for the period between July 2016 and July 2017 for the General Electric (GE) GE14 fuel.
During this period no notification of any changes or errors resulting in a change to the calculated PCT were received from GEH. Therefore the PCT of less than 2170°F for the GE14 fuel and the PCT summary provided in the 2016 annual report (Reference 1) is unchanged.
Document Control Desk L-MT-17-086 Page 2 of 2 Until all the GE14 fuel is permanently discharged from the MNGP core, the annual ECCS reports will continue to be provided for the associated GEH evaluation models (GE14 fuel) and AREVA evaluation models (ATRIUM 10XM fuel).
Should you have questions regarding this letter, please contact Mr. Stephen Sollom at (763) 295-1611.

<2140 Monticello Constant Pressure Power Uprate" G2 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 G3 +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 G4 +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 G5 +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 20 14-03)
This change is due to the use of a minimum ~p that could be G6 +20 non-conservative offering inappropriate steam cooling benefit above the core two-phase level.
