Abstract
The experiment on recording neutrino bursts has been carried out since the mid-1980.
As the target, we use two parts of the facility with the total mass of 242 tons.
Over the period from June 30, 1980 to December 31, 2018, the actual observational time is 33.02 years.
No candidate for the stellar core collapse has been detected during the observation period.
An upper bound of the mean frequency of core collapse supernovae in our Galaxy is 0.070 year-1 (90% CL).
