INTRODUCTION: PURPOSE OF THE REPORT
On December 20th 1995, the Government of Ukraine (“GoU”), the Governments of the G-7 countries and the European Commission (“EC”) signed a Memorandum of Understanding (MoU) on a programme to support the closure of the Chernobyl Nuclear Power Plant. Nuclear safety is one of the four areas developed in accordance with this MoU.
The “Ukrainian NPPs Safety Upgrade Package Program” (SUP) was developed by SE NNEGC “Energoatom” and takes into account all recommendations issued through the final report of the joint project ECIAEA-Ukraine (IAEA report date February 2010 IAEA-EC Agreement 2007/45268) , in accordance with the “Road Map For Nuclear Safety of Operating Ukrainian Nuclear Power Plants” of the MoU.
Within the frame of the SUP preparation, Energoatom selected the Kharkiv and Kiev-based Nuclear Engineering Design Institutes to prepare project technical documentation.
The SUP involves safety improvements at existing NPPs, with no new construction, no capacity increase and no life extension.To comply with the requirements of environmental protection SUP should pass the Ecological Assessment (EA). One of EA tasks is to disclose and discuss the EA report in terms of the public consultation process and working over it after the public consultation process is over. .
The Ecological Assessment (EA) is to be carried out in compliance with the national legislation and international conventions signed by Ukraine, as well as the best international environmental and social guidelines for projects financed by IFIs (including EBRD and EU environmental requirements).
Thus, since SUP foresees the safety upgrade of all 4 operating NPPs wihouth new construction or capacity increase EA of SUP is not fully under the requirements of state construction norms concerning environmental impact assessment (EIA) for new construction. EA process is regulated by the normative document specially elaborated for this case.
This Ecological Assessment Report (EAR) is aiming at providing the wide presentation of EA results including the public consultation results

1.5.3 Purpose of the Upgrade Program The purpose of SUP is further implementation of safety upgrade works in terms of long-term state safety upgrade strategy of power units of Ukrainian NPPs. The selection of measures to be included in the SUP is based on the following: 1. the measures should improve the safety of NPP's operation, under both normal and emergency (accident) conditions; 2. the measures should not change the basic design of the NPPs; 3. the measures were identified on the following basis: • measures that are required by Ukrainian norms, regulations and standards; • international recommendations after IAEA and RISKAUDIT assessments; • measures recommended by the Safety Analysis Reports; • measures required by Ukrainian national supervisory authorities; • measures based on operational experience (feedback from the NPPs).

Energoatom estimated that the total cost to carry out all safety upgrade measures will be in the order of 1.18 G€ and implementation will take 7 years (2010-2017). Energoatom started the upgrade programme with its own resources and will continue to do so in the future, but will require substantial loans to finance the implementation of all measures. The portion of the SUP for which finance is sought is expected to be implemented during the period 2012-2017. The implementation of the measures identified for the SUP is planned according to their priority. The prioritization of the measures was based on a probabilistic assessment of their impact on safety improvement: • quantitative impact of each measure on safety: based on each measure's impact on core damage frequency (CDF) and large release frequency (LRF); and • qualitative impact of each measure on safety: through an estimation of the decision- making factor defined in view of number of factors (frequency of accident initial events, possible consequences, safety functions touched by the measure). As a result of the assessment, measures were classified into 5 categories:
Table 5 – Categorization of SUP measures
Quantitative criterion Qualitative criterion Category - expected impact on safety improvement CDF, 1/year LRF, 1/year Decision-making factor Category 0 - limited impact <1Е-07 <1Е-08 1 Category I - small impact <1Е-06 <1Е-07 2-8 Category II - medium impact <1Е-5 <1Е-6 9-16 Category III - high impact <1Е-4 <1Е-5 17-25 Category IV – very high impact >1Е-04 >1Е-05 >25
Based on this categorization, the SUP activities are organized into 3 priority groups: • Priority I: measures having high/very high impact on safety (Categories III & IV); • Priority II: measures having small/medium impact on safety (Categories I & II); • Priority III: measures having a limited impact on safety (Category 0).

1.7 SUP Connection with Other Programs
1.7.1 Previous programs related to safety upgrade Beginning in the 1980's, several safety improvement programs were developed and implemented by Energoatom at the nuclear power plants. The main programs are listed hereafter in order of their implementation: 1 - Consolidated safety improvement measures for operating power units with VVER and RBMK reactor types” SM-88 and SM-90; 2 - “Safety improvement program for NPPs with VVER-1000, 440 reactor types”, 1994; 3 - “Program of priority measures on safety improvement at NPPs with VVER-1000, VVER-440 reactor types”, 1994; 4 - “Set of safety measures for NPPs in operation with VVER-1000 reactors”, 1999; 5 - “Program of priority safety improvement measures for Ukrainian NPPs”, 1999; 6 - “Complex NPP modernization and safety improvement program” approved by the resolution of the Cabinet of Ministers of Ukraine No. 504-r of 29 August 2002 (this program was developed after Ukraine ratified the Nuclear Safety Convention in December 1997); 7 - “Safety improvement concept for operating NPP power units” approved by the resolution of the Cabinet of Ministers of Ukraine No. 515-r of 13 December 2005 (this program was developed in 2005 after the completion of the previous “Complex NPP modernization and safety improvement program”, and was completed in 2010); 8 - “NPP modernization and safety improvement program of VVER-1000 (В-320) reactor types, part 2 (Khmelnitsky Bloc 2) and part 3 (Rivne bloc 4) 2004-2009. The current safety upgrade program (SUP) for Ukrainian NPPs was developed to further improve safety within the frame of the long-term state strategy on safety improvement of NPPs.

2) while introduction of SUP measures a non-significant increase of rad-wastes is possible. 3) depending on the results of the program, the reassessment of power units safety is possible for relevant aspects.
The possible links between the implementation of mentioned tasks 1-6 and residual impacts of operating NPPs of Ukraine are analyzed in chapters. 2.5.11, 3.5.11, 4.5.11, 5.5.11. The expected impact of SUP implementation to those links is reflected in chapter 2.5.12, 3.5.12, 4.5.12, 5.5.12.
1.8 Alternatives to SUP Implementation
1.8.1 "No-project" alternative The objective of the SUP is to upgrade the operational safety of the 4 operating NPPs of Ukraine through a set of over 800 measures. In this context, the "no project" alternative refers to the absence of implementation of any safety improvement measure included in the SUP. The consequences of the "no project" alternative would be: • the absence of improvement of the operational safety of the NPPs and, therefore, no reduction of the exposure of workers and the public to accident risks; • the non-compliance with Ukraine national standards, norms and safety upgrade requirements concerning NPPs of Ukraine; • the non-compliance with SNRIU requirements, which would be illegal; • the non-compliance with the requirements of international audits carried out by IAEA and RISKAUDIT; • the absence of implementation of the lessons learned from operational experiences. The "no-project" alternative is unacceptable and will therefore not be further discussed. Power unit decommissioning – at the end of a fixed period of operation or earlier- requires that all its security systems and other essential safety equipment are kept operating until the final stop and the first phase of the decommissioning, i.e. until the unloading of spent nuclear fuel. Most of these systems and equipment are also required at the following stages of decommissioning - to complete removal of all wastes from the unit. SUP involves introducing safety upgrade measures that are needed while the certain balance to date of all of their life cycle (the stages of operation and decommissioning). Therefore, the early shut off of NPP without implementation of the SUP activities refers to the non-program alternatives. It should be noted that “Energoatom” does not offer early decommissioning of power units of operating nuclear power plants of Ukraine on its own initiative and the external solution according to the Law of Ukraine “Concerning the Nuclear Energy and Radiation Safety” will be approved by the state authorities which made decisions about construction and is to be brought to the attention of the operating organization no later than two years before final closure. Moreover, as the world (eg, experience of NPP “Greifswald”, Germany) and domestic (experience of the Chernobyl NPP) practice show that in case of early decommissioning duration increases significantly compared to the planned final stop
1.8.2 Other alternatives The objective of the SUP is to upgrade the operational safety of the 4 operating NPPs of Ukraine through a set of over 800 measures. In this context, the word "alternative" refers to any solution aiming at upgrading the safety of the 15 reactors under operation, in a way different from the way proposed in the SUP.
Ukraine NPP Safety Upgrade Program – Ecological Assessment Report – version 5 Energoatom - Date 31.01.2012 Page 23
1.8.2.1 Alternative content of the safety upgrade program The SUP aims at implementing measures that improve the safety of NPP operation in both normal and emergency conditions. The notion of "safety upgrade" refers to any action that allows limiting the exposure (in terms of probability or intensity) of workers, the public and the environment to accidental impacts potentially caused by the operation of NPPs. The SUP includes not only a set of safety upgrade measures, but comprehensively includes all measures that were identified and considered as necessary (1) in compliance with the requirements of Ukraine’s nuclear safety authorities, (2) according to new standards and normative requirements of Ukraine, (3) following the recommendations of international experts from IAEA and RISKAUDIT and (4) based on the operational experience feedback from NPPs. There are no safety upgrade measures that were identified, but then not included in the SUP. The only alternative to the SUP would have been not to include all identified measures in the SUP, and subsequently to lower the level of safety improvements. Such an option was not considered by Energoatom.
1.8.2.2 Alternative planning of implementation of the safety upgrade measures As described in chapter 1.5, the SUP measures were categorized and prioritized in order to identify those which would have the strongest impact on safety improvements. Together with other constraints (procurement and supply times, outage periods, etc…), the SUP implementation plan takes into account the order of priority of the measures, in a way that allows the earliest implementation of those measures which have the strongest impact on safety improvements. The alternative approach to the program implementation with no consideration of the measure priority is less effective.
1.9 State Policy on protection of environment and population health The Law of Ukraine on Environmental Protection (25.06.1991 № 1264) is a framework law that defines general legislative, economical and social rules and requirements for the protection of the environment in the interest of future generations. It is detalized by the list of special laws and codes listed in chapter 1.3.2 adopted aiming at the exact regulatory issues concerning environment. In accordance with the Decision of the Council of National Security and Defense of Ukraine dated 8th April 2011 “Concerning safety upgrade of NPPs operation in Ukraine” approved by the Order of the President of Ukraine No585/2011, “Energoatom” in terms of preventive measures resulting from the analysis of accident on NPP in Japan had elaborated the review of SUP (see chapter 1.6.2).
1.10 Public and occupational safety management at NPP level
1.10.1 Health Safety Environment (HSE) management
1.10.1.1 Legal and regulatory requirements The right of workers to the protection of their life and health on work site, as well as the right to safe and healthy labour conditions is defined by the Law of Ukraine “On labour protection” of 21.11.2002 №224-IV. The key laws that regulate labour protection are: • Law of Ukraine “On labour protection” of 21.11.2002 №224-IV; • Labour Code of Ukraine; • Law of Ukraine “On compulsory state social insurance from accidents at work and occupational diseases that lead to loss of ability to work”;

1.10.1.2 Implementation of HSE requirements In compliance with Article 13 of the Law of Ukraine on “Labour protection”, there is a labour protection department (LPD) in every NPP. LPD is a structural component of an NPP. The main role of LPDs is to organize the implementation of all necessary legal, organizational, technical, sanitary and hygienic measures ensuring safe labour conditions, the prevention of occupational accidents and diseases within each department of the NPP department. LPD together with other departments addresses the following issues: • safety of production and technological processes; • safety of production equipment; • safety and health of working conditions; • sanitary and household services for workers; • provision of individual and collective protection equipments; • organizational and methodological guidelines on labour protection issues; • participation in the elaboration of LPD measures, and elimination of adverse impact of production factors on workers; • control of the effective implementation of LPD measures and assessment of their efficiency. The LPD work concerns all the aspects of industrial safety and factors of potential negative impact on the employees: radiation impact factors, hazardous chemical substances impact, fire danger factors impact, noise impacts, electrical and mechanical risks, negative climate factors impact, etc. LPD also organizes and manages the use of individual protection equipments: glasses, helmets, gloves, respirators, protective electrician’s belts and safety ropes… Besides the general labour protection requirements, specific measures and instructions for the protection and safety of staff are defined for works, operation or technical maintenance of each equipment type.
1.10.1.3 Certification of workers, selection of sub-contractors By the law, workers have to undergo specific training and medical examination before they work in the NPP. As a result of this procedure, each worker is certified for certain type of work in certain parts of the NPP. Employers are responsible for the certification of their workers, which means that the NPPs do not organize the certification of workers hired by sub-contractors.

In practice, NPPs have less HSE concerns with local sub-contractors who they know well and which are trained and examined by the same services as NPPs workers. Conversely, NPPs have more concerns with occasional sub-contractors and therefore control them more closely. One of the criteria for the selection of sub-contractors who comply with certification or license requirements is the price of their services. NPPs cannot reject from a bidding procedure a sub- contractor with whom they had previous unsatisfactory experience. Nevertheless, they can stop the contract of a sub-contractor who does not meet the HSE requirements when working in the NPP.
1.10.2 Early warning and preparedness
1.10.2.1 Information and emergency centers
SNRIU Emergency-Information Centre and Sub-Divisions In accordance to the Decree of the Cabinet of Ministers of Ukraine No 1198 dated 03.08.1998 SNRIU is managing the creation and activities of functional sub-system of Common State System “Safety of nuclear power objects”. On the national level the key element of the sub-system if Information-Analytic Center (IAC) of SNRIU. Activity on the object level is undertaken by the local state Inspections for Nuclear and Radiation Safety USSE functional subsystem "Safety of Nuclear Power Facilities" operates at national, regional and facility levels. Facility-level activities are carried out by on-site State Nuclear Safety Inspectorates while regional-level activities are carried out by State Regional Inspections on Nuclear and Radiation Safety. At the national level, the SNRIU Emergency and Information Centre (EIC) is the key element of the subsystem. The IEC is staffed with skilled SNRIU experts and subordinated organizations. In normal mode of operation, a 24-hour duty is maintained and operational information is received from Ukrainian NPPs, analyzed, recorded, and disclosed via the SNRIU website www.snrc.gov.ua. It is planned to implement at IEC the RODOS decision support system in the event of a radiation accident. To fulfil intergovernmental agreements with other countries on early notification of a radioactive accident, information exchange and cooperation in nuclear safety and radiation protection, communication tests with competent contact centres in Austria, Belarus, Bulgaria, Latvia, Germany, Norway, Poland, Romania, Slovakia, Turkey, Hungary, Finland and Sweden were conducted. SNRIU, as a national point of contact established within the Convention on Early Notification of a Radioactive Accident, participated in IAEA ConvEx-1а and ConvEx-2а exercises to test the communication with the IAEA emergency centre and in ConvEx-2b exercise to work out information exchange with the IAEA emergency centre in the event of a radiation accident.
Energoatom Emergency Centres Energoatom's emergency preparedness and response system is integral part of the USSE functional subsystem of nuclear energy and fuel-energy complex, which is within the competence of the Ministry Energy and Coal Industry of Ukraine. This part of the functional subsystem of USSE includes, assubjects, (i) the main and reserve emergency centres of Energoatom, (ii) and NPPs support centre which have the status of the separated subsidiary ("Technical Emergency Centre" located in the village of Bilohorodka, Kyiv district), and (iii) the separated subdivision "Atomremontservis". In the event of an emergency at NPP, experts of the support centres are sent to the site where they are at the disposal of the site incident commander. Energoatom’s main emergency centre is located at the Headquarters in Kyiv and the reserve one is located in the village of Dniprovske, Chernigiv oblast (former managing centre of Chernobyl NPP). National regulations envisage the establishment of the on-site and off-site emergency centres at each NPP.

An on-site emergency centre is designed to manage accident localization and mitigation actions at the NPP site and in the controlled area. An off-site emergency centre is located in the monitoring zone and is to be involved in the event of such accidents when the onsite centre cannot be used. When an accident occurs at NPP, the whole network of Energoatom emergency centres is activated including, if needed, emergency centres of other NPPs, as engineering and technical support. To ensure a reliable video communication link in emergencies, Energoatom installed a satellite communication system that provides the connection between the main and reserve emergency centres, support centres of NPPs, and emergency centres of separated subdivisions. In 2008 a fibre optic communication link was arranged between Energoatom and Rosenergoatom emergency centre. This link is designated for obtaining consultations from Russian scientific and technical organizations in case of an accident at Ukrainian NPPs.
Emergency Training and Exercises National legislation of Ukraine requires emergency training of the operator’s personnel involved in emergency response actions the NPP personnel and SNRIU specialists inclusive. In detail, SNRIU participates in the following emergency exercises: • on-site emergency situations exercise at NPP with full EIC activation; • on-site emergency exercise without EIC activation, with involvement of the personnel of the Emergency and Information Department; • full-scale emergency exercise, with full activation of EIC; • EIC internal emergency exercise based on a radiation accident scenario with radiological terrorism issues; • international IAEA CONVEX-3 exercise of response to a conditional radiation accident at Laguna- Verde NPP in Mexico without EIC activation and with involvement of the personnel of the Emergency and Information Department; • on-site emergency exercises at NPPs without EIC activation. In 2008, the State Nuclear Safety Inspections at NPP participated in 160 emergency exercises at NPPs, including 39 on-site emergency exercises. Based on the results of such exercises, EIC procedures are subject to revision or improvement.
1.10.2.2 Public awareness In case of accident requiring the information of the public, the NPP informs local and regional authorities and administrations according to existing pre-established lists. The responsibility for informing the population lies on the MoES of Ukraine. On practice the population strongly lacks the information concerning the signals and messages of the early awareness and also concerning the actions which should be undertaken in case of this signal (see chapter “Social environmental impact”) The management of evacuation processes (if deemed necessary) in the satellite city and all other cities is fully under the responsibility of the MoES.
1.10.2.3 Incorporation of experience of Fukushima accident The key initial external action of the accident on NPP “Fukushima” was the beyond design- basis tsunami amplitudes caused by the earthquake which is not possible under conditions of NPPs in Ukraine. However, events such as a loss of energy for any reason, disfunctionning of control systems, inadequate emergency plans, impact of human factors and others require detailed analysis of conditions for all nuclear power plants in the world, including Ukraine NPPs. A possible external factor of severe accident at NPP in Ukraine is the earthquake, which is included in the safety analysis reports. Technical solutions for safety upgrade which are to be implemented in the SUP are the revision of seismic risks. It should be noted that SUP, as any long-lasting program, is a subject to periodic review and amendments and, if
Ukraine NPP Safety Upgrade Program – Ecological Assessment Report – version 5 Energoatom - Date 31.01.2012 Page 27
necessary, will be revised on the basis of detailed analysis of accidents at nuclear power plant of “Fukushima” by the international and national experts and the results of the additional testing of operating nuclear power plants ongoing. In particular the implementation schedule of SUP is revised toward the acceleration of certain measures that have the greatest impact on safety (see chapter 1.6.2). List of ecological and sanitary-hygienic legal limitations
1.11 List of ecological and sanitary-epidemiologic limitations According to Ukrainian legislation, the following ecological and sanitary-hygienic limitations apply to the project: • NPP internal personnel and external citizen exposure to radiation; • concentrations or values for emissions and liquid discharges of radioactive and non- radioactive substances into the environment; • level of impact of ionizing radiation open sources; • volume of chemical non-radioactive emissions into the atmosphere; • harmful substances concentration in the lower atmospheric layer; • volumes of specific water and waste treatment; • size of the sanitary-protection and supervision zone. The radiation safety norm of Ukraine NRBU-97 (НРБУ-97) defines two groups of irradiated persons: the personnel (A and B categories) and the population (C category). According to the НРБУ-97 the next persons are divided into 3 categories: • Category “A” (personnel) – people who are directly working with sources of the ionizing radiation (either permanently or on a short-term basis); • Category “B” (personnel) – people with are not directly working with the sources of the ionizing radiation but who can be irradiated because of the nature or location of their work; • Category “C” – the whole population. Ionizing dose limits set by the norms are presented in the table below.
