Title | Offsite Notification Due to Release of Amertap Balls Into the Mississippi River |
Event Description | On 2/14/2013, Xcel Energy personnel determined that approximately 44% of the Amertap balls recently used were not recovered. Monticello Nuclear Generating Plant is required to report to the Minnesota Pollution Control Agency (MPCA) when greater than 20% of the Amertap balls are not recovered. This is based on an agreement with the MPCA dated September 12, 2008. The MPCA was notified at 1710 CST on 2/14/2013.
The licensee has notified the NRC Resident Inspector.
Update for 50.72 non-emergency notification number 48754: The referenced report number was made at 1831 EST on 2/14/2013. This report stated the Minnesota Pollution Control Agency (MPCA) was notified that 44% of Amertap balls recently used were not recovered at 1710 CST on 2/14/2013. Due to a miscommunication between the Monticello Nuclear Generating Plant Chemistry Department and the Xcel Energy Corporate Environmental Services contractor, the actual MPCA notification was not made until 0930 CST on 2/15/2013. This update report is to ensure the correct time of the MPCA notification was documented. The licensee notified the NRC Resident Inspector. Notified R3DO (Pelke). |
