Over a year after the war in Ukraine began, the NEA continues to collect information from verifiable and reliable sources to support its members’ efforts to maintain an understanding of the state of nuclear safety and radiological protection in that country. The OECD has continued to further broaden, deepen and strengthen its engagement and co-operation with Ukraine. The NEA, in partnership with the United Kingdom, has recently launched an NEA-Ukraine Visiting Experts Programme, which will bring Ukrainian nuclear energy experts to the Agency.
Because our Ukrainian colleagues are faced with a highly uncertain, ever-changing and very challenging situation it is to be expected that obtaining detailed information on a regular basis may not be possible.
Electricity grid
- The electricity grids of Ukraine and Moldova were successfully synchronised with the Continental European Grid on 16 March 2022.
Nuclear power plants
- In Ukraine 15 pressurised water reactors of Russian VVER design are operated by the State Enterprise National Nuclear Energy Generating Company “Energoatom” at four plants. These plants operate under nuclear safety regulations implemented by the State Nuclear Regulatory Inspectorate of Ukraine (SNRIU).
Zaporizhzhia nuclear power plant has six reactors.
- 4 October: The Zaporizhzhia nuclear power plant (ZNPP) restarted Unit 4 to generate steam for safety systems, following repairs to address a water leak. Unit 4 had been shut down after a leak was found in a steam generator pipe weld. With the pipe now repaired and tested, Zaporizhzhia will transition Unit 4 from cold to hot shutdown, allowing it to produce steam again. Unit 6, which had been providing steam since mid-August, will now return to cold shutdown.
- 29 September: With the completion of an eleventh groundwater well, the ZNPP is now able to supply around 250 cubic metres of water per hour. This is the level estimated to be necessary to maintain the level of the 12 sprinkler cooling ponds used to cool the six reactors and spent fuel stored at the plant. The Ukrainian authorities report that the level of the cooling pond remains stable.
- 22 September: A tenth groundwater well was completed, bringing the plant closer to a longer-term solution for the provision of cooling water to reactors in a shutdown state. Over 200 m3 of water per hour can now be supplied to the sprinkler ponds that cool the ZNPP’s six reactors and spent fuel. The wells were bored following the destruction of the Nova Kakhovka dam downstream from the site on 6 June and the subsequent draining of water from the Kakhovka reservoir.
- 22 September: A significant number of staff are reported to have left the ZNPP since the start of the war, including licensed operators from the main control rooms. IAEA observers at ZNPP were informed that recruitment of additional staff from Russian nuclear power plants is ongoing and that these staff are being trained and licensed to operate the plant under Russian Federation regulations.
- 15 September: A further two groundwater wells to supply the sprinkler ponds that cool the six reactors and spent fuel were brought on line, bringing the total of new wells to nine. The water supply situation at the plant will be reassessed once a tenth well has been constructed in order to assess whether more will be needed.
- 8 September: ZNPP staff indicated that there were now seven wells operating at the site supplying just over half of the water currently needed (250 m3 per hour) to maintain the cooling water in the plant’s sprinkler ponds. The remaining volume of cooling water is currently pumped from the site’s drainage system. As a result of the new wells, the ZNPP staff reported that the height of the groundwater had only declined by a very minor level.
- 4 September: Each ZNPP reactor has three separate and independent redundant systems (commonly called “safety trains”) that together comprise the unit’s safety systems. Safety trains are normally in stand-by mode, ready to activate if needed to maintain the reactor unit’s safety. A single safety train is capable of maintaining the reactor unit’s safety. A water leak was detected in a recirculation valve of one system of one safety train of the ZNPP Unit 5. In order to repair the valve, one safety train of Units 5 and Unit 6 had to be placed offline. Once the valve had been repaired, the Unit 6 safety train was returned to standby mode, while the Unit 5 safety train was kept offline for maintenance.
- 1 September: ZNPP staff reported that four groundwater wells were now in operation, out of a total of 10-12 wells planned to be drilled around the plant’s sprinkler ponds. The wells are intended to become the main source of cooling water for the six shutdown reactor units and spent fuel pools, following the destruction of the Nova Kakhovka dam downstream from the site.
- 22 August: ZNPP began pumping water from a new groundwater well to serve its cooling needs. The well was bored following the collapse of the Nova Kakhovka dam downstream from the site on 6 June and the subsequent draining of water from the Kakhovka reservoir. The new well was reportedly providing about 20 m3 of water an hour. It is planned to drill an additional 10-12 wells at the site.
- 13 August: ZNPP reactor Unit 6 reached a hot shutdown state to generate steam for various nuclear safety purposes at the plant, replacing Unit 4.
- 11 August: ZNPP reactor Unit 4 was moved from hot shutdown to cold shutdown following the detection of a water leak in one of its four steam generators. To continue production of steam at the site preparations to move Unit 6 into hot shutdown mode were begun. The 750kV power line providing ZNPP with the electricity needed for reactor cooling and other essential nuclear safety and security functions was disconnected twice in the course of the day, meaning that the plant had to rely on its only remaining 330 kV backup power line to supply the required electricity.
- 29 July: The planned transition of ZNPP Unit 4 to hot shutdown was completed, while unit 5 transition to cold shutdown. The planned maintenance activities include inspecting and testing safety systems which protect the reactor and its fuel as well as cleaning of the heat exchanger.
- 12 July: Preparations to move the ZNPP reactor Unit 4 from a cold shutdown state to hot shutdown began. The ZNPP unit 5 is currently in hot shutdown, a state used to generate steam for various safety purposes that include the processing of liquid radioactive waste collected in storage tanks. Once in cold shutdown preventive maintenance activities that can only be carried out while in cold shutdown will be performed. All other units remained in cold shutdown. The SNRIU, Ukraine’s national regulator, issued regulatory orders on 8 June to limit the operation of all six units on the site to cold shutdown state only.
- 5 July: The main 750 kilovolt (kV) power line providing the ZNPP with the electricity needed for reactor cooling and other essential nuclear safety and security functions was disconnected at 01:21am local time on 4 July. A recently reconnected 330 kV line prevented full loss of external power until the restoration of the 750 kV line some 12 hours later.
- 3 July: A 330 kV line to help supply the ZNPP’s external electricity needs for the ZNPP was reconnected to the plant on 1 July. This line supplements the existing 750 kV line currently meeting these needs. Before the war began in February 2022, four such 750 kV lines were available to the plant.
- 21 June: Some of the cooling water needs for the ZNPP were reportedly being met using a discharge channel of the Zaporizhzhia Thermal Power Plant (ZTPP). This water was used to supply the ZNPP’s spray ponds which cool the six reactors in shut down mode and the plant’s spent fuel storage. The ZNPP spray ponds have also been replenished using a drainage system fed by underground water near the ponds.
- 8 June: The SNRIU issued a regulatory order for the ZNPP reactor 5 to be placed into a cold shutdown state. The unit is currently in hot shutdown to produce process steam for such site operations as the treatment of liquid radioactive waste. Such waste is collected from all six reactors, even when in cold shutdown.
- 6 June: Water levels in the reservoir that supplies the ZNPP fell throughout the day following the breach of the Nova Kakhovka dam downstream from the facility. Onsite back-up options remain available and are estimated to be sufficient for up to several months. Water is needed for residual heat removal from the reactors and used fuel ponds, as well as to cool emergency diesel generators when they are in operation.
- 22 May: The National Nuclear Energy Generating Company Energoatom reported that the 750 kV main external power line providing the electricity needed for reactor cooling and other essential nuclear safety and security functions at ZNPP was cut.
