Monticello Inspection p Activities 2013 Ref Refueling eling O Outage tage

  • In July y 2013, Monticello completed p a three month refueling g outage g

during which several substantive plant modifications were made to support the extended power uprate.

  • The NRC identified numerous examples of human performance issues associated with inadequate contractor control, inadequate procedures or work instructions, and with management decision making/oversight which resulted in several findings of low safety making/oversight, significance.

Action Matrix Summary January 2013 - December 2013 Licensee Regulatory Multiple/Rep Unacceptable Response Response Degraded Degraded Performance I II Cornerstone Cornerstone V III IV In the first quarter of 2013, Monticello was in Column 1 Licensee Response Column. In the second quarter, the plant moved to Column 3Degraded Cornerstone Column. This was due to a (substantial safety significance) involving the plants failure to have procedures in place to fully address the effects of an external flooding scenario.

9

Monticello Assessment Results Monticello was one of only 9 plants nationwide to be assessed in the Degraded Cornerstone Column.

Monticello was also the only Region III plant to be assigned a substantive cross-cutting issue in the area of human performance, specifically complete, accurate and up-to-date design documentation, procedures and work instructions.

Due to the decline in performance, Monticello will receive increased inspection and oversight until corrective actions taken prove to be effective and sustained performance improvement is observed.

NRC Actions In 2014

  • Supplemental 95002 inspection for Fl di Flooding
  • Routine, baseline inspections
  • Substantive Cross-Cutting Issue in Human Performance
  • Dry Cask Storage

Monticello Inspection p Activities Yello Finding for External Yellow E ternal Flooding

  • On June 11,, 2013,, the NRC issued a Yellow findingg for the licensees failure to maintain a procedure fully addressing the design basis external flooding event. The issue was documented in Inspection Report 2013009.
  • This issue was identified as part of the agency follow up actions in response p to the Fukushima nuclear event.
  • This finding will remain open until the NRC completes a 95002 supplemental inspection.

12

2014 Supplemental 95002 Team Inspection

  • The objectives of the 95002 inspection are to provide assurance that:

- the causes of the deficiency are understood

- the extent of the issue has been identified

- corrective actions will prevent reoccurrence

- safety culture has been evaluated 13

Monticello Inspection p Activities Dr Cask Storage Dry

  • Monticello has loaded 16 dry fuel storage canisters
  • In October 2013,, the NRC identified that weld tests were performed improperly on one canister. Subsequently, the licensee identified five additional canisters with improper weld tests.
  • The NRC is confident the casks are leaktight because multiple additional tests were performed on the closure welds that demonstrated no leakage. The casks are also subject to radiation monitoring which has not shown any elevated radiation levels.
  • The NRC is evaluating the licensees actions to address this issue.

14

Monticello Inspection p Activities E tended Power Extended Po er Uprate

  • On December 10,, 2013,, the NRC approved pp the licensees request for an extended power uprate (EPU) , to raise the current licensed power from 1775 to 2004 MWt (a 13%

increase).

  • The NRC is evaluating the licensees actions to implement the EPU.
