U1.03/06A1 - lot 1 Incinerator for Zaporozhye

In the framework of the TACIS 2006 Programme, the European Commission agreed with NAEK-Energoatom and Rivne & Zaporozhe Nuclear Power Plants (RNPP and ZNPP) on the funding of the Solid Radioactive Waste Treatment Projects for these NPPs, which included the design, purchase and installation of equipment for the retrieval and the treatment of solid radioactive waste on the Rivne and Zaporozhe NPP sites.

The objective of the Radioactive Waste Treatment project was to resolve the issues of treatment of radioactive waste, whether already accumulated or to be produced during plant operation. The project enabled ZNPP to

• improve efficiency of the radwaste treatment processes;
• reduce of the radwaste volumes in the storages by incineration / super compaction and fragmentation
• obtain the end products compliant with the recommended criteria of the long-term storage/disposal;
• ensure compliance with the international safety requirements, implementation of the ALARA principles in the course of the radwaste handling.

The specific objective of the project is the radwaste preparation and subsequent treatment with the use of high-technology equipment and with the application of incineration, a super compacting and fragmentation equipment. The end product of treatment is high-density product suitable for long-term storage. The use of the advanced equipment with the maximal level of mechanization and automation will reduce the time of the personnel in contact with radwaste. The state-of-the art control systems with the minimum of controlled parameters should allow to effectively respond in case of emergency. Also, the system should allow to minimize the amount of radwaste accumulated at the storages as a result of the NPP operation and maintenance.
The TACIS-financed contribution to the Radioactive Waste Treatment project was split into 3 supplies:

• U1.03/06A1 Lot1 - Incineration facility
• U1.03/06A1 Lot2 – Emission Monitoring Systems, Surveillance Camera System, Mobil Decontamination Device for the incinerator facility
• U1.03/06A1 Lot 3: Super Compaction facility.
• U1.03/06A3 Lot 4: Fragmentation Equipment.

The present project covered the supply of the Incinerator facility.
The Incineration Facility has a capacity of 30 kg/h solid waste and about 12 kg/h liquid waste.
The operating area of the Incineration Facility begins at the acceptance point of the 280 l drums containing the SRW in primary packages (polyethylene bags) and ends with the output of the 170 l drums filled with the ash from the ash removal module.
The solid radwaste, in primary packages, will be transported in 280 l drums from the existing radwaste treatment building to the feeding module of the incinerator, in the new extension building.
The liquid radwaste will be conveyed to the new extension building via pipelines and stored in an existing buffer tank of 5 m3 capacity; subsequently, it shall be injected into the incinerator as required.
The furnace ensures a sufficient and effective incineration of the solid and liquid radwaste, in accordance with the requirements of the Directive 2000/76/EC, as well as the reference levels for the radiological emissions valid for ZNPP. Its design characteristics meet the requirements set out in the Technical Specification.
The Incineration Facility shall consist of the following main modules:

• Feeding systems
• Furnace and afterburner chamber
• Flue gas cleaning system
• Ash removal system
• Instrumentation and control (I&C) system

The process of incineration shall be possible in the automatic, as well as remote manual control modes.

The first set of Technical Specifications for the project was developed in 2004 under the service contract "Radwaste Treatment Complex for Zaporozhe NPP – U1.03/04" (Contract 99687). After failure of the tender procedure in February 2008 the Technical Specifications were revised under the service contract "On-site Assistance to Zaporozhe NPP – U1.03/06A1" (Contract 132885) and retendered in May 2008 (EuropeAid/126869/D/SUP/UA).
The contract with the supplier of the facility IBERDROLA, Spain was signed in January 2009.
The new equipment has been installed in the new extension of the existing Radwaste Treatment Facility building. The new extension building has been planned, erected and financed under the responsibility of Energoatom and ZNPP.
The equipment was installed by ZNPP under supervision of the supplier. The site acceptance test (SAT) was performed in November 2015 and the Provisional Acceptance Certificate (PAC) was signed on 23.12.2015. The Final Acceptance Certificate (FAC) was signed after expiration of the warranty period.
The achievement of this project, when the rad-waste building is completed and all equipment (EU and Energoatom financed) is installed, is to ensure the safe handling and storage of radioactive waste originating at Zaporozhe Nuclear Power Plant.
Follow-up project has CRIS number 370110.
