2.0 Site Status Summary

The La Crosse Boiling Water Reactor (LACBWR) is owned and was operated by the Dairyland Power Cooperative (DPC). LACBWR was a nuclear power plant of nominal 50 Mw electrical output, which utilized a forced-circulation, direct-cycle boiling water reactor as its heat source. The plant is located on the east bank of the Mississippi River in Vernon County, Wisconsin. The plant was one of a series of demonstration plants funded, in part, by the U.S Atomic Energy Commission (AEC). The nuclear steam supply system and its auxiliaries were funded by the AEC, and the balance of the plant was funded by DPC. The Allis-Chalmers Company was the original licensee; the AEC later sold the plant to DPC and provided them with a provisional operating license.

LACBWR was shut down on April 30, 1987. The SAFSTOR decommissioning plan (DP) was approved on August 7, 1991. The DP is considered the post-shutdown decommissioning activities report (PSDAR). The PSDAR public meeting was held on May 13, 1998. DPC developed an onsite independent spent fuel storage installation (ISFSI) and moved the spent fuel to the ISFSI in 2012. DPC had been conducting incremental dismantlement and decommissioning activities until the middle of 2014, when it was decided to return the facility to SAFSTOR until additional personnel resources could be acquired to complete the decommissioning effort.

On June 1, 2016, the operating license was transferred from DPC to LaCrosse Solutions for the purpose of completing decommissioning at LACBWR. On September 24, 2019, the NRC approved an order that will allow the LACBWR license to be transferred back to DPC upon completion of decommissioning at the site and termination of the Part 50 license outside of the ISFSI.

The license termination plan (LTP) for LACBWR was submitted on June 27, 2016 (ADAMS Accession No. ML16200A095). The staff issued the LTP amendment, safety evaluation, and environmental assessment on May 21, 2019 (ADAMS Accession No. ML19008A079).

On May 24, 2022, the NRC approved the partial release of certain Class 1, 2 and 3 survey units based on the Final Status Survey Report and supporting information (ADAMS Accession No. ML22122A230).

On February 24, 2023, the NRC approved the release of remaining Class 1 survey units based on the Final Status Survey Report and supporting information (ADAMS Accession No. ML23055A027).

Final license termination activities at LACBWR, and the LACBWR 10 CFR Part 50 license is effectively terminated outside the footprint for the remaining onsite Independent Spent Fuel Storage Installation (ISFSI), which encompasses approximately 39 acres.
