This report describes the results of the Shawnee Lime and Limestone Wet Scrubbing Test Program conducted by EPA s Industrial Environmental Research Laboratory, Research Triangle Park, North Carolina (IERL-RTP). In this program, flue gas desulfurization (FGD) tests were conducted at the EPA 10 MW prototype Shawnee Test Facility located at the Tennessee Valley Authority (TVA) coal-fired Shawnee Power Station near Paducah, Kentucky. Bechtel Group, Inc. of San Francisco was the major contractor and test director, and TVA was the constructor and facility operator. Results of the program before July 1978 have been reported elsewhere (1.2) ... 

A primary objective of the EPA alkali wet scrubbing test program during the last several years has been to enhance SO2 removal and improve the reliability and economics of lime and limestone wet scrubbing systems by use of adipic acid as a chemical additive.

The Melt Attack and Coolability Experiment (MACE) program is addressing the ability of water to quench and thereby terminate a MCCI. This paper provided a summary of MACE Test MIB, which investigated the interaction of 416 kg of 70% oxidized PWR corium with a limestone/common sand concrete basemat in the presence of a water overlayer. Key findings from this experiment are summarized as fol1ows ... 

The decreasing levels of SO2 and increasing frequency of car traffic has resulted in a new multi-pollutant situation in many urban and industrial areas. In order to possibly quantify the corrosion effects caused by this new multi-pollutant situation an extended exposure program was performed that took place between 1997 and 2001 and involved some 30 test sites in 18 countries in Europe and North America [91]. Specimens of carbon steel, zinc, copper, bronze, limestone, paint-coated steel, and glass representative of medieval stained glass windows were exposed for up to four years. At each site, the environmental data measured included climatic parameters (temperature, relative humidity, and sunshine radiation), gaseous pollutants (SO2, NO2, HNO3, and O3), particles (presented as PMio, i.e., concentration of particles with diameter < 10 pm), and precipitation (total amount, conductivity, and concentration of, i.e., H+, S04 , N03, Cl", NH4+).
