Hot functional testing has begun at Slovakia’s Mochovce-4 nuclear power plant in southwest of the country, owner and operator Slovenské Elektrárne said.
Hot testing typically spans several weeks and involves a series of tests on key systems to verify their performance under standard operating conditions, conducted without loading any nuclear fuel into the reactor core.
“With the hot hydro test, we are in the next stage of the inactive testing programme,” said Branislav Strýček, president and chief executive Slovenské Elektrárne.
He said first fuel loading for the VVER-440 pressurised water reactor (PWR) plant is expected to happen this year, but subject to a series of testing.
