Survey of Piledriver results and preliminary interpretation of three postshot cores in and near the cavity

Description: A summary of measured data collected by numerous agencies cooperating in the Piledriver event, is presented together with calculations based on empirical relations deduced from past events in comparable media. Of 9 relations that have been proposed to predict cavity radius, 5 result in radii accurate to <3.5%. The remainder are off by about 10 to 18%. Three postshot recovered cores (U-15.01 PS-1, -2, -3) were examined on a gross scale prior to extensive detailed sampling for laboratory tests… more

Half-plant low dichromate evaluation at KW Reactor: Production Test-176. Final report

Description: This final report details production test-176, the primary purpose of which was to provide a quantitative comparison of fuel element 8001 aluminum alloy cladding corrosion in cooling water containing 0.5 and 1.0 ppm sodium dichromate inhibitor. Secondary purposes were to provide information on cladding corrosion as a function of temperature and as a function of time at both inhibitor concentrations. The primary purpose was well fulfilled: Equations were developed to describe and predict fuel el… more
