Subject:

Response to July 5, 2022 Request for Additional Information for Class 1 Excavation and Basement Survey Units

Reference:

1) Marlayna Doell, U. S. Nuclear Regulatory Commission, E-mail to Gerard van Noordennen, EnergySolutions, Questions for La Crosse Solutions - July 7, 2022 Call, dated July 5, 2022 As a follow-up action to a conference call held on July 7, 2022 with the NRC Staff, and in response to a request for additional information (RAI) in Reference 1, LaCrosseSolutions is providing the enclosed additional information. The conference call was initiated to resolve any remaining questions on the NRC review of the Class 1 final status survey (FSS) area reports for the La Crosse Boiling Water Reactor site.

As a result of discussions on June 7, July 7, and August 24, 2022, with the NRC staff on the ongoing LACBWR FSS report review, an error was identified in the release record for the Waste Treatment Building (WTB) Excavation (Survey Unit L1-010-101C related to judgmental sample L1-010-101-FJ-GS-C16-SB). The sample result shows a concentration of 154 pCi/g of Cesium-137, which was determined to be a typographical error based on LaCrosseSolutionss determination that scans of the excavation slopes performed on September 12, 2017, identified no elevated areas.

The response to the RAI is provided in the attachment. The enclosed CD contains the supplemental information discussed in the RAI response and requested by the NRC Staff.

There are no regulatory commitments made in this submittal. If you should have any questions regarding this submittal, please contact Gerry van Noordennen at (860) 462-9707.
