Containment Checking for Tightness Successfully in Progress

Tightness checks of Unit One containment at Temelin nuclear power plant have started their second half. The twenty-four hour guaranteed measurements checking tightness of the containment at the positive pressure of 70kPa will be completed today at 8 p.m. The test proper in which fifty NPP and contractors' workers have been directly taking for five days part will be finished in the night from this 3rd to 4th August. "Tests are carried out under the direct supervision of experts from the State Office for Nuclear Safety and Institute of Technical Inspection. Results as per protocol to be prepared by VUEZ Tlmace, the research institute carrying out the measurements, will be known on Thursday at about midday," added Temelin NPP press spokesman Milan Nebesar.

"The preliminary measurement results achieved so far indicate that the containment will pass very well also the verification tightness test. The next verification test, periodical one this time, will be carried out on the Unit One containment at the first replacement of fuel, i.e. in about a year following the start of operation of the unit. Later this year strength and tightness tests of Unit Two containment will be carried out," supplemented the information Pavel Vojta from the section of containment integrity tests at Temelin NPP.
