INVESTIGATION OF [beta]-EMISSION METHODS OF MONITORING COOLANT WATER LEVEL IN NUCLEAR POWER PLANTS

This investigation was performed on a vessel heat-engineering bench. The working medium was water under pressure up to it 20.5 MPa and temperature from 20 (cold) to 350[degrees]C (hot). The controllers were a [beta]-emission sensor of level and a Sapfir-22DD differential manometer as the standard. T...

Description
Summary:This investigation was performed on a vessel heat-engineering bench. The working medium was water under pressure up to it 20.5 MPa and temperature from 20 (cold) to 350[degrees]C (hot). The controllers were a [beta]-emission sensor of level and a Sapfir-22DD differential manometer as the standard. The objective was to determine the characteristics of a [beta]-emission sensor under the conditions of the working medium. Analysis of the experimental data showed that the indications of the [beta]-emission sensor and differential manometer were identical and linear as a function of the level of both the cold and hot water. The characteristics of the [beta]-emission sensor are: minimal response time and measurement error, very small dimensions, serviceability at pressures to 20.5 MPa and temperature to 350[degrees]C, at least 10 years life, and energy independence of the primary converter.
