Optimization of the fusion accumulator with a porous heat-conducting nozzle is carried out. Calculation of temperature dependences of the cooled object on the time of cooling and porosity of the heat-conducting nozzle are obtained. Results of experimental study of the cold accumulator with the porous nozzle are submitted. Calculation and experimental data are compared. %8 2008-12-10
