The following question was asked by a member of the public during the ICP CAB's October 25, 2018 meeting in Sun Valley, Idaho. The answer to the question is provided by DOE-ID staff.
Answer: Not directly. We’d been aware of degradation in the CPP-749 wells for some time prior to the fire water leak. In 1997, our contractor made five fuel transfers out of the CPP-749 dry wells to begin dealing with the situation. When we received authorization to construct a spent fuel packaging facility, fuel transfers were put on hold to avoid handling the fuel more than necessary. However, the spent fuel packaging facility was later cancelled. We are now in the process of addressing the problem by improving the ventilation of the dry wells, and making plans to eventually remove the fuel from the first generation vaults where the problem is focused.

The following questions were submitted via question cards by a member of the public during the ICP CAB's February 21, 2018 meeting in Idaho Falls. Answers to the questions are provided by DOE-ID staff.
Answer: DOE signed a Record of Decision in the mid-1990s to consolidate fuels with similar cladding at specific sites. DOE has not decided to fully implement this decision at this time.
Answer: The well was located next to CPP-666. It was used to dispose of service wastewater, which consisted primarily of plant cooling water, demineralizer and boiler blowdown water, and condensates from the Process Equipment Waste Evaporator (PEWE). The well was fed from the PEWE building. It was used from 1950 to 1984, and was officially closed in 1989.
Answer: DOE is prepared to provide the CAB with information about what studies have been done on calcine storage facilities if requested.
Answer: The DOE analysis of AMWTP continuing mission is not complete. DOE is refining its analyses to assess the challenges, cost-effectiveness and viability of a continuing mission for AMWTP.
Answer: INL/ICP carbon tetrachloride releases to air are well below levels that require ambient air monitoring at the INL Site, Idaho Falls, or other locations.
