{{#Wiki_filter:_ SfaY 1) Quanti y and categorize by volume, point f storage, activity level and isotopic content the radioactive wate, inventory a t TMI 2.

Response

Table 1 contains a list of the contaminated water volumes in Unit 2. 2 The list is divided by approximate activity levels of Cs-137 which should be the contrciling isotope at the time of processing. The source of the water is also included. M W h tanks containing radioactivity are located in the a siliary, M ara '- ~ f' : ' ' ' :_;. Figure 1 is a map of the Unit 2 site shcaing the locations of tne various builoings and structures. Figures 2 and 3 show the location of the discharge points to the Susouchanna River. Figure 4 shows the location of the water intake at Columbia, approximately 15 miles down river from TMI.
