Subject:
Discontinuation Agreement Regarding Groundwater Monitoring at Zion ZionSolutions is requesting the Nuclear Regulatory Commission (NRC) concurrence regarding the termination of the groundwater monitoring program at the Zion facility. Groundwater monitoring has been ongoing throughout the decommissioning process and is performed on a quarterly basis.
During the ZionSolutions monitoring period, only 'very low levels of tritium have been identified.
ZionSolutions is proposing that the groundwater sampling program be discontinued one quarter after the completion of all demolition activities and removal of all radwaste from the site. The last of the sacrificial soil used to demolish the Containment Buildings has been shipped offsite. Therefore, the last groundwater samples will be taken in the fourth quarter of,2019.
A summary of groundwater sample results to date is provided in Attachment 1. Tritium was not detected at a concentration greater than 200 pCi/L in the eleven samples collected during the 3rd quarter 2019 RGPP sampling round. Additionally, gamma-radionuclides, hard-to-detects (Fe-55 and Ni-63, and Sr-90 wt:;re not detected in groundwater samples collected during the 3rd quarter 2019 RGPP sampling round. The attached table summarizes the findings of the August 2019 sampling round. If any sample result anomalies occur between now and when the final samples are taken, ZionSolutions will commit to additional sampling as agreed to with the NRC.
Several verbal discussions with the NRC have taken place regarding the termination of the groundwater monitoring program and it is our understanding that there is mutual agreement regarding the proposal for termination of the program. We are requesting NRC concurrence of this proposal via written communication.
