The progress of the two-phase flow research can be divided into four stages. These period are 1948-1958, 1960-1970, 1971-1979, and 1980-1990. In this 8th Report, the development of researches on the flow oscillations and flow instabilities in boiling channels in the latter period of the second period (1960-1970) has been described. And the experimental studies on the flow instabilities in boiling channels related to boiling water reactors conducted at nuclear power laboratories in variuos countries have been introduced.
