Abstract

The water flowing in a nuclear reactor is analyzed, while the reactor is in operation, by conducting water from the reactor vessel substantially without reduction in pressure or temperature past test surfaces (e.g. tubes) with different electrochemical potentials relative to the reactor water. Deposits formed on the test surfaces, which are substantially caused by colloidal particles in the water, are examined, preferably with regard to radioactive content.
