Water and Heat Flow Simulation After Underground Nuclear Test

Based on the information about the damaged zone and local hydraulic data of CHESHIRE which is an underground nuclear test at the Nevada Test Site, a model was developed to simulate water and heat transport process using FEFLOW software. The temperature descending curve of the melt glass was acquired. The simulated temperature was consistent with the measured data. According to the simulation result, the temperature descending process obeys an exponent decay function, and the groundwater convection mainly affects the melt glass temperature descending process.
