摘要

Callaway Nuclear Station is located in Callaway County,Missouri,80 miles west of St.Louis.The 5,228- acre plant site is also about 10 miles southeast of Fulton on an elevated plateau overlooking the Missouri River to the south.Callaway Nuclear Station is a single unit 1240 MWe Pressurized Water Reactor (PWR),owned and operated by AmerenUE,and has been in operation since October 1984. rnIn August 2000,Callaway Nuclear Station began evaluating their in-plant liquid waste processing system to determine if the plant's evaporators,which had been used since plant startup,should be replaced with a filter-demineralization system.The primary justification for performing a plant modification was the excessive dose received while operating the plant’s evaporators,as well as the cost of maintaining the current plant equipment and processing the residual bottoms from the plant’s evaporators. rnThis project was completed in two phases:Phase One of the project included evaluation,selection and installation of a temporary full size liquid waste processing system.Phase Two of the project included evaluation of the performance of the temporary system,and installation of a permanent system. rnFor Phase One,Callaway established the following evaluation criteria for the full size liquid waste processing system: rn1.Personnel exposure rn2.Processing cost rn3.Solid waste generation rn4.Effluent quality rn5.Equipment reliability rn6.Vendor experience rnCallaway received bids for liquid waste processing systems from three vendors.The technologies that were presented included:ultra-filtration,reverse osmosis,chemical injection and demineralization technologies.The decision was made by Callaway in December of 2000 to install a full-scale liquid waste processing system consisting of an ultra-filter(UF),solids collection system and demineralization vessels.The full-scale ultra-filtration system was installed as a Temporary Modification to the Callaway Plant.Following a two-year operation period,the system's performance was evaluated to determine whether to make it a Permanent Modification to the Callaway Plant.The results of Callaway’s evaluation were as follows: rn1.The Ultra-filtration System(UF)was very effective at removing solids and Co60 rn2.The self contained mechanical filter(solids collection system)worked well to remove the reject from the UF membranes rn3.Effluent quality matched the performance of the plant evaporators
