This paper describes possible regimes of thermohydrodynamic processes in a closed natural-circulation; loop including a heat exchanger with vertical steam-generating pipes in which water boils within the pressure range 8-90 kPa. A diagram is presented of the experimental unit. The vertical steam generating pipes of the heat exchanger are made of stainless steel 0Kh18N10T. There are 101 pipes. Oscillograms of fluctuations in pressure above the steam-generating pipes, the pressure in the condensation chamber, and the liquid level in the down pipe are shown. The dependence of the periods of the thermohydrodynamic oscillations in the natural circulation loop are presented.
