IAEA announces installation of new diesel boilers at Zaporizhzhya NPP
Kyiv • UNN
The IAEA notes that Zaporizhzhia NPP is installing four new mobile diesel boilers to perform important nuclear safety functions. Nine boilers are currently in operation, and experts are monitoring safety and maintenance, despite the ongoing challenges posed by the war.
Zaporizhzhya Nuclear Nuclear Power Plant (ZNPP) is installing four new mobile diesel boilers to to generate additional steam needed to perform various nuclear safety functions at the site. safety functions at the site, including waste treatment. This was announced by the Director General Director General of the International Atomic Energy Agency (IAEA) Rafael Mariano Grossi, reports UNN.
Details
It is noted that the team of of IAEA experts present at the ZNPP observed the installation work during the last Sunday, and was subsequently informed that the new boilers would be ready in the near future. Currently, there are nine mobile boiler rooms at the site, eight of which are used for winter heating. of which are used for winter heating.
Nuclear power plants require a significant amount of steam to carry out important operations on the sites. This also applies to Zaporizhzhia NPP, although it has not been generating electricity for more than a year. has not been generating electricity for more than a year. The IAEA encourages the installation of diesel boilers for this purpose, and we welcome the planned additional capacity
Five reactors remain in cold shutdown mode, while unit 4 is in hot shutdown mode to produce steam and heat, including the neighboring hot shutdown to produce steam and heat, including for the neighboring Enerhodar, where most of the plant's personnel live.
Almost three weeks after ZNPP suffered the eighth complete blackout during the war, ZNPP remains connected to two external power sources: the main 750 kilovolt (kV) main power line and a 330 kV backup power line.
Addendum
In recent days, the IAEA experts IAEA experts also visited the 750 kV electrical distribution station, the entry point for the external electricity needed for the plant, and at the on-site water treatment plant. on site. During another walk, they inspected the ZNPP cooling pond, cooling towers, inlet and outlet channels, as well as the outlet channel of the Zaporizhzhya CHPP, located nearby. This time, however, they were not allowed to the isolation gate of the of the cooling pond.
Separately, IAEA experts were informed by ZNPP that they were unable to access the reactor roofs as planned on December 19, due to security concerns. No alternative date has been set has not yet been determined. This year, the IAEA has already gained access to three roofs reactor roofs - units 2, 3 and 4 - but not the others.
In addition, the IAEA team was again denied access to the northwestern part of the turbine hall of the reactor during a site visit last Monday, despite a request, made prior to the visit. The IAEA was unable to visit the northwestern part of of any of the six turbine rooms since mid-October.
