5593-GPN-17149

The following notice refers to goods, works and services to be procured through open tendering for projects financed by the Kozloduy International Decommissioning Support Fund which is administered by the European Bank for Reconstruction and Development (EBRD).

Kozloduy Nuclear Power Plant Ltd

Kozloduy International Decommissioning Support Fund

In November 1999, the Bulgarian Government and the European Commission signed an Understanding in which the Bulgarian Government undertook a firm commitment to close and decommission Units 1 - 4 of the Kozloduy Nuclear Power Plant (NPP) at the earliest possible dates. The Kozloduy International Decommissioning Support Fund (KIDSF) has been established and administered by the European Bank for Reconstruction and Development (EBRD). One of the purposes of this Fund is to finance, or co-finance preparation and implementation of selected projects, which would require procurement of goods, works and services for modification of existing plant systems and construction of new decommissioning facilities in an environmentally safe and cost effective manner.

A Project Management Unit has been established and is in operation on the Kozloduy NPP site to manage the projects notified below.

This General Procurement Notice is an update to the General Procurement Notice published on 2nd August 2006, and draws attention to the following new upcoming procurement activities:

• Control of liquid and gaseous releases for the units under decommissioning at Kozloduy Nuclear Power Plant.

In 2004 the EC issued a Recommendation (2004/2/Euratom) to standardise the information for radioactive substance release from Nuclear Power Plants to the environment. This includes liquid and gaseous releases. During the decommissioning phase, decontamination operations will take place which could lead to airborne and liquid discharges that need to be monitored.

The procurement notice is for supply and installation of equipment in line with the recommendations.

• Facility for retrieval and processing of the solidified phase from evaporator concentrates tanks located in auxiliary buildings I and II at Kozloduy Nuclear Power Plant.

Evaporator concentrates are currently stored in 10 tanks in Auxiliary Buildings 1 and 2 in a volume of about 5000 m3. Some of these concentrates have been stored in the tanks since 1974 and have precipitated out to form solid crystalline and liquid phases in the tanks. The removal of the liquid and solid crystalline phases is required to empty and clean the tanks and allow dismantling work to start.

The procurement notice is for the two following scope:

Provision of a service for detailed sampling of the contents of the tanks to determine the chemical, radiological and physical properties of the concentrates. 

Supply of technology and equipment for retrieval, conditioning and storage of the evaporator concentrates (salts). One of the key requirements is not to increase the volume of the salts as a result of removal and conditioning.

• Evaluation of the radiological inventory of Units 1-4 optimisation of the conditioning and packaging regimes for the wastes associated with the dismantling process.

This procurement notice is for the following two phases:

First phase:

Provision of complete service for detailed evaluation of the radiological status of equipment, structures, compartments and rooms of Units 1-4 of the Kozloduy NPP. Assessment of the total radiological inventory of the units in order to harmonise the dismantling process with waste packaging and storage.

Second stage:

Based on the results of the radiological inventory, provision of service in form of a feasibility study, for optimisation of the packaging and the storage regimes of waste.

The optimisation of the waste storage facilities in Bulgaria will also be reviewed, particularly with respect to very low level near surface waste facilities.

• Dismantling and Decontamination Tools and Equipment

The procurement notice is for design, supply and installation of technologies, tools and devices for the dismantling process. This will include equipment for fragmentation and decontamination workshops, for dismantling of civil structures other than buildings e.g. foundations, concrete tanks, etc.

• Preparation of the implementation of “Construction of Heat Generation Plant”

As part of the physical separation of infrastructure of Units 1-4, an independent source of steam and heat will be required. This source will be powered up only if both units 5 and 6 are shut down temporarily for maintenance purposes. However it will have to have enough capacity to supply heat for all 6 units and for the district heating loop of Kozloduy town

The procurement notice is for design, supply and implementation of a heat generating station.

• Preparation of the implementation of the separation of infrastructure of Units 1-4

Some interconnecting items of infrastructure (power, water, steam, etc.) will have to be modified in order to fully separate the units under decommissioning (Units 1 to 4) from the ones under operation (Units 5-6).

The procurement notice is for design, supply and implementation of these modifications.

• Decontamination and Treatment Equipment (DTE), Emergency Boron Tank EBT equipment

The purpose of the Decontamination and Treatment Equipment (DTE) is to remove the loose contamination from the surfaces, floors and other components of the pools and tanks.

• Independent Environmental Impact Assessment for Project for supply of a Facility for Treatment and Conditioning of Radioactive Wastes with High Volume Reduction Factor (VRF)

This Project is to provide an Independent Environmental Impact Assessment (EIA) for the described facility.

Among the currently available technologies, the Plasma Melting Technology will achieve the volume reduction factor required and a Plasma Melting Facility will be installed at KNPP for processing the historic Solid Low and Intermediate Level Radioactive Wastes currently stored and for the future wastes yet to be generated.

The assignment has to be carried out in compliance with the relevant environmental standards and regulations of Bulgaria and in compliance with the EBRD’s Environmental and Public Information Policies. Under the EBRD Environmental Policy the project would be screened as A-level, requiring an Environmental Impact Assessment and public consultation as set out in the Bank’s Environmental Policy.

• Supply of Vehicle Exit Monitors, Weighbridges to Gates 3 and 6 and Supply of Additional Monitors

Vehicle Exit Monitors

Vehicle Exit Monitors to be provided at Gate 3 and 6 to ensure the activity of materials leaving the KNPP site is below the radiological threshold for release. The monitors shall be based on multi channel gamma radiation detection The Contractor shall supply, install and commission the monitors at each location. The Contract will also provide operator training for the site staff.

Weighbridges

Weighbridges to be provided at Gate 3 and Gate 6 to enable logging of material weight as it leaves the KNPP site and ensure the road transport regulations are complied with. The weighbridge shall be road surface mounted and use load cell technology. The Contractor shall supply, install and commission the weighbridges at each location. The Contract will also provide operator training for the site staff.

Supply of Additional Monitors

A portable germanium detector for in-situ measurement of gamma radioactivity  is required for monitoring the areas outside the controlled area. One unit has already been purchased for use within the controlled area, this additional unit will remove the need to transfer the monitor across radiological zones.

• Supply of size reduction and decontamination workshops for Kozloduy NPP Site

This project is to provide a range of facilities and equipment for size reducing and decontaminating dismantled materials from the Turbine Halls and Auxiliary Buildings at Kozloduy NPP Units 1-4 as addressed in PMU-DTR-ENPR-0617. The proposed facilities are envisaged to be used also for size reduction and decontamination of the dismantled materials from the other plant areas, including the Reactor Building.

Project will be implemented and split into the following phases:

 Design, construction and supply of equipment for size reduction and decontamination workshop.

 Design and supply of equipment for size reduction areas inside the Turbine Hall

 Supply of hand-held equipment for size reduction and decontamination workshop

• Environmental Impact Assessment for decommissioning at KNPP site

The purpose of this project is to prepare an independent Environmental Impact assessment as required by Bulgarian regulations

An updated Decommissioning Strategy has been established; it has been approved by KNPP and the Bulgarian Authorities in June 2006. This Strategy is based on a continuous and immediate dismantling process. Dismantling can be started only after the Issuance of a Decommissioning Permit by the Bulgarian Nuclear Regulatory Agency (BNRA). Prior to issue of this permit, an Environmental Impact Assessment (EIA) for the decommissioning shall be prepared. The Decision made by the Ministry of Environment and Waters based on this EIA is a prerequisite for the Decommissioning Permit Issuance.

The assignment has to be carried out in compliance with the relevant Environmental Standards and Regulations of Bulgaria and in compliance with the EBRD’s Environmental and Public Information Policies. Under the EBRD Environmental Policy the Decommissioning of a NPP would be screened as A-level, requiring an Environmental Impact Assessment and public consultation as set out in the Bank’s Environmental Policy.

• Supply of Equipment for Removal of Liquid Borate Waste

Provision of materials and equipment to allow KNPP personnel to install pipe-work systems to remove the liquid phase from the Borate salt tanks prior to removal of the solid phase
