Description: Analysis of atmospheric response data from three nuclear chimneys, DH3, DH5 and DH6, has been made using two different analytical solutions. A simple one-dimensional linearized model is used to predict the pressure response at depth in a chimney to surface pressure variations. Comparison of computed and measured downhole pressure histories shows a good fit over times of up to 25 days for all three chimneys. Assuming a nominal value of 1/3 for porosity, the permeability in darcies is computed to be 63 for DH3, 12 for DH5, and 57 for DH6. (auth)
