Processing and interpretation of measured results during CILRT in nuclear power plant

Tokom 10. mjeseca 2016. provodio se integrirani test curenja na tlaku u slučaju nezgode u NE Krško. Test je proveden u pet faza i prije provođenja bilo je potrebno pripremiti kontejnment na način da se odrede lokakna curenja pomoću lokalnih testova curenja tipa B i C. Za vrijeme provođenja testa mjereni su tlak, temperatura, relativna vlažnost, temperatura kondenzacije i volumni protok. Obrada mjerenih podataka provodila se pomoću tri standardom predviđena postupka da se dobije podatak o curenju kontejnmenta. Rezultati testa zadovoljavaju sve kriterije i pokazuju da je curenje kontejnmentskih puteva ispod propisanih granica. Nakon završetka testa određeni su novi težinski faktori senzora temperature i relativne vlažnosti koji će u budućnosti služiti još boljoj obradi podataka.During the October of 2016., an integrated leakage rate test was performed at full pressure in NE Krško. The test was carried out in five phases and it was necessary to prepare the containment before the start in such a way as to determine the local leakage rate using local leakage rate tests of types B and C. The pressure, temperature, relative humidity, dew temperature and volume flow were measured during the test. The processing of measured data was carried out using three standard procedures for obtaining data on containment leakage rate. The test results meet all the criteria and show that the leakage rate of containment paths is below the prescribed limits. After the test was completed, new weight factors of the temperature sensors and relative humidity sensors were determined, which will enable even better data processing in the future
