Working report: ABSTRACT

The bedrock at the Olkiluoto and Hästholmen research sites contain saline groundwaters. To locate
saline waterbearing zones, a new instrument was constructed. The instrument consists of a temperature
and fluid resistivity measuring unit and a special flow quide unit. The salinity (TDS) can be calculated
from the temperature and fluid resisitivity of the fluid. When pumping water from a hole water from
rock flows with the aid of flow quides to the sensor and the salinity of the section selected can be
measured. The new instrument was tested in VTT test hole and measurements were carried out at the
Olkiluoto site in boreholes KR1, KR2, KR3, KR4 and KR9.
