SUMMARY In this paper, we have attempted to review the extent of our statistical design and analysis activities for the NAEG since 1971. This review includes our activities during Calendar Year 1977 with regard to Mound Study 2, nuclear site studies, and planning for possible future cleanup efforts at Clean Slate 2. We have also pointed out the current status of these projects for future planning purposes. We wish to note again the following: 1. Pu and Am concentrations on over 500 new soil and vegetation samples from safety-shot sites are essentially ready for statistical analysis to update estimates of Pu spatial pattern and inventory. These data are in the NAEG data bank and also on computer cards at Battelle-Northwest. Three hundred twenty soil samples have been collected at the grid intersections in Figure 5 at NS-201, but have not been shipped to analytical laboratories for radionuclide analyses. If these data are obtained, they would be useful for estimating spatial pattern and inventory of radionuclides at NS-201l. Plans are ready for Phase 1 sampling to begin at several nuclear sites including NS-200 discussed in this paper and NS's-202 and 203 as discussed by Essington (1978). Design plans for additional studies at Clean Slate 2 in anticipation of a possible cleanup effort at that site have been submitted to the NAEG. Samples of the type specified in recent EPA guidelines should be collected for evaluation of their applicability to NTS and TTR sites. Statistical analyses for the estimation of Pu inventory in blow-sand mounds at Area 13 and Clean Slate 3 are completed (Gilbert and Essington, 1977). Particle size and spatial distribution aspects of Pu and Am are suggested as future blow-sand mound studies. FIDLER and other mobile field detectors should continue to be evaluated for their applicability to field studies. Special studies aimed at calibrating more closely these instrument readings to Pu concentrations in field samples are encouraged. A comprehensive synthesis of NAEG data needs attention. A defini- tion of "synthesis" is needed before such an effort begins. 475
