In this booklet the uranium atom nucleus fission as well as electricity generation in a nuclear power plant (primary circuit, reactor, reactor pressure vessel, fuel assembly, control rod and reactor power control) are explained. Scheme of electricity generation in nuclear power plant and Cross-section of Mochovce Nuclear Power Plant unit are included. In next part a reactor scram, refuelling of fuel, instrumentation and control system as well as principles of nuclear safety and safety improvements are are described
The Slovak Republic is the country with very insufficient amounts of primary sources. That is why almost 90% of used fuel has to be imported. In addition Slovakia does not have direct access to the sea and cheap tankers transportation is not available. The only possibility for Slovakia in the near future from the point of needs and increasing electricity generation is nuclear power. As part of the former Czechoslovakia, Slovakia started to build the second nuclear power plant in the Mochovce village. Consequently with huge political and social changes in November 1989 and essential deficiency of investment money construction of nuclear power plant was stopped. Under considerable press by the non-governmental organizations (i.e. Greenpeace etc.) one of the main reason was to find out the formulation of feasibility and economic advantages of Mochovce completion very thoroughly and precisely even though the first unit has been completed approximately by 80%. As a grant from the European Union some financial sources were given to promote training process. Some financial sources obtained from the grant by the European Union have been given to promote the training process in the Slovak Republic. A brief description of methods which have been carried out to determine the best economic option for development of the company is part of material. Result is the only reasonable option is to complete nuclear power plant Mochovce not only from economic point of view. Several international pre operational audit team reviews by nuclear safety teams were sent by IAAE Vienna. Goals of these teams were to examine if safety is at the appropriate and accepted level and if the next operation would be acceptable. Models which are presently used in Slovenske elektrarne, a.s. have all the features of integrated resource planning

Purpose of the Feasibility Study was to define in detail all technical, economic, financial, legal and authorization aspects of Mochovce NPP Unit 3 and 4 completion in order to provide Slovenske Elektrarne, a. s. (SE) and ENEL Top Management with all the necessary information for a final decision on Mochovce Unit 3 and 4. Feasibility study has started in January 2006. SE had the commitment to complete the Feasibility Study within 12 months from Closing of SE acquisition (April 2007). In order not to delay completion of Mochovce Unit 3 and 4, SE has decided to perform, in parallel to the Feasibility study, also all design and permitting activities which are required for the completion of Plant. This has involved anticipation of expenses for approximately 700 MSKK (or approx. 20 MEuro). SE was able to announce the positive decision about completion on Mochovce NPP Unit 3 and 4, two months in advance of the deadline.
On 4 and 5 December, 2006, Fulvio Conti, Executive Director of ENEL, visited Slovenske elektrarne (SE). On the first day of his visit, he met with the Slovak Prime Minister Robert Fico. At the meeting, apart from energy prices, they discussed the completion of Blocks 3 and 4 of Mochovce Nuclear Power Plant. ENEL, which holds 66 % of shares in Slovenske elektrarne, should present to the Government within end of April a study on completion of construction of the blocks MO34. The completion of construction of the Mochovce blocks would amount to approximately EUR 1 billion 600 million. In the afternoon, he met with the representatives of SE's management, who presented to him the results achieved in the area of operational safety, costing, and electricity trade. On the second day, he visited the Mochovce nuclear power plant, where in the morning, there was held a meeting with financial analysts at international level. SE's General Director and Chairman of the Board of Directors, Paolo Ruzzini, had a presentation on introducing SE, then Marco Arcelli, Director of Strategic Development of ENEL Group for Central and Eastern Europe and Vice- Chairman of the Board of Directors of SE, had presentation on an Enel's increase in the Centrel region. Jaroslav Holubec, Director of Mochovce Nuclear Power Plant, summed up the operational results, and Giancarlo Aquilanti, Director of MO34 Power Plant, summed up the plans for the completion of Blocks 3 and 4 of Mochovce Nuclear Power Plant. After answers to the questions, the guests viewed a control room and turbine room of Block 1. (author)
Mochovce NPP was originally planned for operation with four WWER-213 440 MW reactor blocks. Mochovce units 1 and 2 were commissioned in 1998 and 2000, respectively. Construction of Mochovce units 3 and 4 was temporally suspended in 1992 due to a lack of financial resources. At present, construction of units 3 and 4 is approximately 30% complete in terms of technology and approximately 70% complete with respect to construction works, representing a total investment currently valued by Slovenske elektrarne, a.s. (SE) at approximately of SKK 18.9 bn. It is currently estimated by SE that the expenditures necessary to complete Mochovce units 3 and 4 amount to approximately SKK 42.5 bn, 45% of which for supplies and 55% for construction and assembly works. SE is considering various financial options for financing of the investments, including using project finance techniques as Mochovce units 3 and 4 are still considered as a plant under the construction
In Mochovce site the construction of four units of WWER 440 NPP with V-213 type of reactor is being carried out. The financing of Mochovce units completion was resolved in April 1996. The completion work commenced at the construction site under leadership of SKODA Prague, the general supplier. The completion work on building part and tests of constructional electric distributions and lightning constructors started. The revisions in technological part were finished, and final protocols from revisions are the basis for starting of completion work. The assembly of transport container anchorage,ventilation system in hermetic areas and hermetic coverage of pools for stored spent nuclear fuel is being carried out. The pre-completion tests of instrumentation and control of ventilation systems, individual dosimetric control in medical station, and tests of nuclear programme according to commissioning and assembling work schedule at the equipment for physical protection of the NPP area started. Inspection activities at Mochovce were performed in accordance with inspection plan for 1996. Evaluation of routine inspections was performed by means of quarterly protocols. Main findings from the inspections performed in Mochovce were in the following areas: (a) deficiencies in the knowledge of the respective regulation and conditions from the Resolution of the state regulatory body, concerning selected employees; (b) training of the selected employees; (c) aim of the measures imposes by inspectors is to eliminate deficiencies in preparation of programmes for pre-completion and completion testing. NRA SR assessment activities at Mochovce NPP were focused mainly on approving and inspecting of design modification to approving programmes for pre-completion and completion testing of system s and equipment and on approving quality assurance programmes. The suggestions of international missions, which reviewed Mochovce safety in the years, were taken into consideration in the programme
Mochovce Nuclear Power Plant has been an open project involving a wide international co-operation of numerous organisations of countries stretching from the Atlantic coast up to the Urals that make it a truly European project. The units at Mochovce are the later V-213 type of Soviet-designed WWER-440 reactors. They therefore incorporate a number of improvements over the earlier V-230 type. There are four units at Mochovce site: unit 1 has been in operation since summer 1998, unit 2 is currently in the stage of commissioning tests and scheduled for operation by the end of this year, and unit 3 and 4 are still waiting for the final governmental decision about their completion, currently 40% and 30% completed respectively. Beginning in 1981, the construction works were stopped in early 90's due to the decision on replacement of the original I and C system, as well as lack of funding afterwards. Slovenske elektrarne, a.s. have been working to resuscitate the project focusing initially on completion of the units 1 and 2 with assistance of western companies. one month later the governmental guarantees were given for loans and Slovenske elektrarne signed loan agreements to finance the project completion, as well as construction completion agreements with contractors.

At the end of 2002 Mochovce NPP as the first Slovak energy operation got the international certificate of environmental managership according to norm ISO 14 001:1996 on production and electric energy supply from nuclear power plant praised by reputable testimonial company Det Norske Veritas. Slovenske elektrarne, a.s. management has intention to pass a certification process in all of its operations in this and following year. Certification presentation is one of the results of project of Environmental policy of SE, a.s. as it was specified by company executive in 2000. This project comes out from Environmental protection conception of SE from 1997. The basic condition of success of whole project is total orientation of Slovak electric energetic on energy production with minimal environmental load. It means the maximal exploitation of water and nuclear production of electric energy at the expense of technologies based on energy raw materials incineration. In 2002, of totally produced 32 805 MWh of electric energy almost two thirds were produced by nuclear power plants, almost one fifth by water power plants and 16% by thermal power plants. Thanks to this electricity production structure it is sharply possible to cut back the emission capacity produced by thermal power plants

FluBlok contains three times more HA than TIV and does not contain egg‐protein or preservatives. This review discusses the four main clinical studies that were used to support licensure of FluBlok under the ‘Accelerated Appro...
Minister of Economy of the Slovak Republic Pavol Rusko would like to see the power plant in Mochovce finished. Press agency SITA quoted his statement that in case of privatisation of Slovenske elektrarne (SE), a.s., Bratislava investor should be searched that would be willing to complete the third and fourth blocks of the nuclear power plant. Last week a tender for sale of a 49-percent stake in SE was repeatedly launched when a privatisation advertisement was published in local and international press. Through a resolution announced last summer the cabinet allowed other companies to participate in the tender (as a reaction interest shown by Czech CEZ). CEZ would be interested in all areas of SE and not only in its conventional part as the other prospects. It is well possible that the number of prospects interested in nuclear energy may increase. Boss of SE, Miroslav Rapsik shares this view and last week announced that there would be probably at least two or three prospects that may be interested in SE as a whole. Amongst them some Russian companies. General Manager and Chairman of Board of Directors, Jaroslav Mil does not wasn't to speculate on under what conditions CEZ may agree with completing of Mochovce. He adds that building any source of nuclear power anywhere in Europe is very difficult without a clear support of wide political spectrum of the specific country. And he needs another assurance: that the cabinet would guarantee that it would eliminate all political pressure from side of the European Union.' In regards to a semi-finished source, according to J. Mil, it made a difference whether this was offered free or with all the fixed costs. 'First we have to see the figures,' he adds. Works on the third and fourth block were stopped in 1992 due to lack of funds. Based on the advise of privatisation advisor the semi-finished blocks were taken out of the privatisation. According to latest analysis the finalization would cost up to 43 billion Sk (1.04 billion
The design of Mochovce NPP was based on the Novo-Voronez type WWER-440/213 reactor - twin units. Seismic characteristic of this region is characterized by very low activity. Mochovce NPP site is located on the rock soil with volcanic layer (andesit). Seismic reassessment of Mochovce NPP was done in two steps: deterministic approach up to commissioning confirmed value Horizontal Peak Ground Acceleration HPGA=0.1 g and activities after commissioning as a consequence of the IAEA mission indicate higher hazard values.

The present position of Slovenske elektrarne, a. s., Bratislava (SE) before its privatisation is presented. Privatisation of SE will be encumbered by problematic spheres, which no potential investor is interested in. E.g. nuclear devices operation and also specifically solution of questions connected with liquidation of A-1, laying up of V-1, completing of the third and the fourth block in Mochovce, encumbered by old debt as well as making the largest water energy centre in Gabcikovo operational, limited by international contract with Hungary by international court decision. Czech CEZ, a.s. was interested in purchase of SE as last, encouraged by considerations about possible advantages of re-fusion of Czech and Slovak energetics. It can be expected the decrease of installed output in SE sources (about in 1400 MW) after 2006 in consequence of early laying up of some production capacities, e.g. Bohunice NPP V-1

Implementation of the Severe Accident Management (SAM) in Slovenske Elektrarne, subsidiary of ENEL, is a process initiated well before the Fukushima Daiichi accident. The main goal was to cover, comprehensively, level 4 of the Defense in Depth (DiD). The process included development of plant specific severe accident management guidelines (SAMGs) and installation of hardware modifications dedicated to mitigation of severe accidents as an upgrade the original VVER-440/V213. The SAM modifications have been developed with the aim to address all main generic vulnerabilities of VVER-440/V213 containments identified during initial analysis supporting the development of plant specific SAMGs. SAM modifications, in addition to their original purpose, improved plant response also at the level 3 of DiD. SAM modifications installed on VVER-440/V213 units in operation or under construction in Slovakia can be considered as an independent and diverse provision for the main safety functions: core subcriticality, core heat removal and confinement integrity. Basic set of SAM modifications includes independent diesel generator (DG), independent external source of borated water and containment vacuum breaker. Major contribution to safety from SAM modifications has been proved to be the implementation of in-vessel retention, hydrogen management in the containment and reliable depressurization of RCS. The complete set of SAM modifications installed incorporates dedicated SAM I and C to allow for determination and monitoring of plant status via dedicated instrumentation and control of SAM equipment installed at plants during a severe accident. SAM project including updating of SAMGs has been successfully completed on both units of Bohunice NPP and respective activities are continuing on operating units no. 1 and 2 in Mochovce with expected deadline in 2015. The basic design of Mochovce units no. 3 and 4 that are under construction has been modified to incorporate hardware changes
The approach of the Mochovce nuclear power plant to nuclear safety improvement is highlighted. The solution of major safety problems is described for the following areas: general problems, reactor core, component integrity, technological systems, instrumentation and control system, electrical systems, containment, internal risks, external risks, accident analyses, operation.

Full text: Brief description of nuclear facility. Slovenske elektrarne - ENEL utility operates two nuclear power plants in southern Slovakia - Bohunice and Mochovce nuclear power plants. Both plants are of the same design (WWER 440/V213). The Mochovce plant operates two units; Unit 1 has supplied electricity to the network since 1998, and Unit 2 since 2000. The Mochovce units rank among the newest WWER 440/V 213 nuclear blocks and benefit from all the improvements already made at the plant. Overview of OE arrangements. The basic management expectations concerning the OE programme are defined by the utility's policy. Assessment of the effectiveness of the OE programme is performed locally at the plant and independently at the utility level. This utility assessment serves as input to overall improvement process of OE programme at the plant. Management arrangements. The IAEA performed a pre-OSART mission in 1994 before the Mochovce plant began operation. Based on the recommendations of the mission, the Mochovce plant established an OE programme and an organizational structure to support it. The plant operation started with a fully functioning OE system. The plant director is responsible for implementation of an effective OE programme, in accordance with the national regulatory body requirements, WANO and IAEA expectations and the utility's policy. The OE programme owner is head of the safety division, who ensures that reported events and near misses are screened and analysed, and that corrective actions are taken with regard to the safety significance of the problem. Implementation of daily activities connected with the OE programme, screening, investigation of events, assessment of effective implementation of the corrective actions taken, assessment of OE programme effectiveness through performance indicators, and updating information in the OE database are the responsibility of head of the OE section. The section is located in the Safety Division and consists of
The cooperation between the western countries and the countries of ex-eastern block in the field of nuclear safety is recent and still limited. The main reasons for this situation are limited or non existent capabilities of these countries for financing as well as non acceptable legal conditions concerning the third party nuclear liability in this part of Europe. Nevertheless, Framatome and Siemens associated in the consortium named EUCOM, have signed in April 1996 the contract of about 100 million US dollars with Slovak electricity company (SLOVENSKE ELEKTRARNE-SE) for upgrading the Units 1 and 2 of Mochovce Nuclear Power Plant according to the western safety standards. This is the first important project involving west-european companies in the modernisation of Russian type of pressurized water reactor (VVER 440/213). The consortium will cooperate with other partners involved in the project: Slovak, Czech and Russian. The financing of the project will be provided mainly form Slovak and Czech sources. The safety upgrading will be financed through French and German buyer credits. French company Electricite de France (EDF) will be the consultant for SE. The safety upgrading measures have been elaborated taking into account the recommendation of Vienna International Atomic Energy Agency (IAEA) and the evaluation of the safety realised by RISKAUDIT, the common organization of German and French safety authorities (GSR and IPSN). Hence all guaranties have been taken to fulfil the western safety criteria for Nuclear Power Plant Mochovce. (author)

History of Mochovce NPP is quite long and reflects political changes that happened in Europe in the end of 80'ties. The plant site was chosen in south-west of Slovakia in the frame of Nuclear Industry Development Plan adopted by former Czechoslovak government in 70'ties. In that time was decided to build in Mochovce four VVER 440/213 units together with other NPP's (Dukovany, Temelin, Kecerovce)
The report gives the basic technical data and history of the construction of the units 3 and 4 of the Mochovce NPP.The current status of the units completion according to the original plan is: civil part - 70%; mechanical part - 30%; electric and IC equipment - 1%. Strategic plan for the preservation of the units 3 and 4 has been developed in accordance with TECDOC-1110. In implementation of the plan preservation activities are performed for the components located and built-in on the site and in storehouses. Preservation with dryers and protective coatings is applied. The factors of possible component degradation are determined. Ventilation components are used for improving the climate conditions in the primary part of the reactor building. Temperature and humidity measurements are done and temperature control is set. Special pre-service inspections beyond the basic scope of preservation and protection works are conducted of steam generator and reactor pressure vessel. The implementation of the design data protection and enhancement is discussed. The feasibility study of units 3 and 4 completion funding has been developed in 2002

The so called 'Mochovce Problem' was one of the major topics in Polish media in the period from May to July 1998. The nuclear power plant commissioning caused an unexpectedly strong reaction, especially in the newspapers, slightly less so in electronic media. Faced with clearly hostile media reaction to Mochovce NPP, the National Atomic Energy Agency representatives, together with atomic and nuclear experts, undertook to change these attitudes. In numerous interviews, letters to the editors and talks with journalists, they attempted to correct the mistakes, explain the true safety situation in the nuclear power plant, by whom it was constructed, who supervised and tested the systems and so on. The completion of Mochovce NPP construction improved significantly the electricity balance in Slovakia, thus decreasing the pressure for continuing the operation of older Bohunice V1 units beyond their design lifetime. For this reason, as well as in view of striving for improvement in environmental factors beyond Polish southern border, especially after Kyoto/97 decisions on greenhouse gases emissions, the public opinion in Poland should support the Mochovce NPP construction. In 1996 Poland has signed with Slovakia a bilateral inter-governmental agreement on the prompt notification on nuclear accidents and on the cooperation in the nuclear safety and radiological protection matters. On the basis of this agreement the experts from Polish National Atomic Energy Agency are in perpetual contact with Slovakian Nuclear Regulatory Body and in each and every moment can obtain full and comprehensive information on the plant parameters iportant for nuclear safety. The experts explanations, together with the NAEA top management visit to the plant itself, brought some results. The media became less aggressive, and Polish public and authorities - contrary to the Austrians - do not protest loudly against the commissioning of this newest European NPP. Now, in December 1998, the tune of
The Project 'Mochovce Units 3 and 4 Completion' started in 2009 and it will be finished in 2013. VUJE, Inc. is one of the five main Project contractors for the Nuclear Island and it is responsible, inter alia, for Mochovce Units 3 and 4 commissioning. The commissioning of Units 3 and 4 includes the stages of Physics Commissioning and Power Commissioning. This paper deals with the preparation of Mochovce Units 3 and 4 Physics Commissioning. In the paper there is presented a preparation of some commissioning documents, e.g. 'Quality Assurance Programme', 'Commissioning Programme', 'Stage Programme for Physics Commissioning', 'Test working programmes', 'Neutron-physics characteristics for Physics and Power Commissioning', etc. The scope of Physics Commissioning is presented by list of tests. For assessment of tests results so-called three-level acceptance criteria will be applied: realization, design and safety criteria. In the paper there are also presented computer codes, which will be used for neutron-physics characteristics calculation and the fuel loading scheme for the reactor core of Mochovce Unit 3. (Authors)

The challenge that SE a.s. took up in April 1996 to start Mochovce units 1 and 2 within a very demanding time frame and in satisfactory conditions is on the way to being wined. EMO managed to put in place an organisation able to ensure the continuity of the design and construction works and to integrate the requirements of modern safety. EDF is proud and happy to contribute to this effort by making available its expertise and experience in building and operating nuclear power plants. The success of Mochovce will not only contribute to the Slovak electricity needs coverage, but will be the first demonstration of a soviet design nuclear power plant brought to international safety standards.

Paper is focused on new acceptance criteria for physical startup tests of Mochovce Units 1, 2. The acceptance criteria are discussed at the stage of their development. The acceptance criteria determination is based on statistical processing of differences between the experimental and theoretical values of neutron-physical characteristics. The experimental values were taken from physical startup tests of Bohunice Unit 1, 2 and 4 and Dukovany Unit 1 - 4. The theoretical values were calculated by code BIPR-7. The acceptance criteria were established for critical boron concentration, core loading symmetry measurement, boric acid worth, temperature reactivity coefficient, 'ejected' control rod worth, pressure reactivity coefficient and power reactivity coefficient. The new acceptance criteria were applied to evaluate results of physical startup tests of Mochovce Unit 1 in June 1998. The acceptance criteria showed to be adequate. The summary results of statistical processing and the comparison of earlier, new and US acceptance criteria for physical startup tests are presented.(Authors)
For the Mochovce NPP safety measurements project realisation, a list of totally 87 safety measures grouped according their purposes to reach recent international requirements on nuclear safety and reliability was elaborated. In this paper an overview of the Mochovce NPP safety measures is given and it is stressed on the measures related to the PSA (AA-08 - Shutdown and Low Power PSA (SPSA) and AA-10 - Full Power PSA Level 1). The scope of PSA level 1 and SPSA projects developed for Unit 1 are described and the main results are discussed. The Core Damage Frequency (CDF) calculation, contribution of the IEs to the shutdown CDF (total CDF=3.83E-06/year) and to the full power CDF (total CDF=1.66E-04/year) are shown. The developed PSA models can be adopted in the future for the following purposes: living PSA; real time risk monitoring; technical specifications and STIs optimization; level 2 PSA
The approach taken by the Mochovce NPP management to safety culture is described. Activities implemented at the plant since 1986 with the aim to enhance the safety culture level through each employee's firm awareness of the safety culture issue and so to minimize the impact of the human factor on operational events in all safety areas are highlighted. The approach to safety culture at the plant was ultimately reflected in the culture of the whole company. (orig.)

Commissioning of the Mochovce Nuclear Power Plant unit 2 fully completed the Mochovce unit 1 and 2 project. The power plant construction passed through a complicated evolution since early 80's. The genesis started with the change of the plant location due to a seismic resistance requirement raised by the former Czechoslovak Atomic Energy Commission, change of the design and contractor of the Instrumentation and Control system in early 90's, halt of construction in 1993 till 1996 due to a lack of funding, as well as a series of international reviews of safety aspects. All the obstacles had been overcome in the end, and completion works were re-started in 1996. Looking back to the unit 1 and 2 completion project, I would like to highlight some aspects of the project, particularly the level of safety, technical and organisational conditions, and terms of funding. The most important argument for completion of the plant was that VVER 440/213 reactor units were distinguished with very high level of passive safety, even overcoming Western-type PWR's in some aspects. The replacement of the original I and C system was another important contribution to the initial level of safety. International safety reviews performed at Mochovce NPP between 1990 and 1995 (Siemens, EdF, IAEA, RlSKAUDIT) confirmed the high level of safety of VVER 440/213 reactors, however, pointed out at some safety issues which had not been dealt with in the design. Those included e.g. the 'external risks', primary-to-secondary leaks, qualification of pressurizer safety valves, and others. It is necessary to stress that the Safety Improvement Programme defined for Mochovce NPP to comply with international standards did not become the most important part of the completion project due to external pressures, but based on natural requirements on nuclear power plant safety level generally accepted in 90's. The good example could be the seismic resistance of the plant which, though designed as seismic resistant
The system dynamic approach presented in this study by modelling the behaviour of Slovak market on the basis of system dynamic model (Forrester model), enables real mix in the extend of 12 years and helps understanding of the market limits. In addition this tool can be used for sensitivity calculations depending on many parameters to develop possible trends in the economic development of the Slovak Republic. If both nuclear power options are maintained then it becomes obvious that electric excess energy is produced and could be exported. This export option remains for the situation that a strong growth of the gross national product is assumed without any increase in energy efficiency. Between these extremes is the scenario that Bohunice 1, 2 off is balanced by Mochovce 3, 4 on and increasing demand this will lead to more moderate but still not negligible potential of CO2 increase. Switching off Bohunice 1, 2 and not switching on Mochovce 3, 4 leads to energy need which must be counterbalanced either by investments in other power plants or by import energy. As far as domestic production is concerned even assuming 50 % CHP production leads to partly remarkable additional CO2-production which might infringe on a long term basis with the Kyoto goals. Assuming additional CO2-emissions from increasing traffic real problems can be expected in such a case. To maintain national nuclear capabilities in Slovakia is very important for today and for future of nuclear energy option in enlarged European Union. (authors)
In this presentation author deals with actual status of project Mochovce NPP units 3 and 4 completion. Present state of Mochovce NPP, Units 3 and 4 enables real assumption to completion. It is expected that such supplier companies can be used which are experienced in field of nuclear projects. Based on budget of 2002, it seems that completion costs of 45 billions SKK are real. These figures were confirmed by study performed by TRACTEBEL in 2004. Based on experience from Bohunice NPP completion as well as from Mochovce NPP, Units 1 and 2 completion and if decision milestone and project start up deadlines will be observed according to modified preliminary schedule of Mochovce NPP Units 3 and 4 completion, it seems as real that Unit 3 will be completed till 06/2011 and Unit 4 - till 12/2011.
A draft is described of starting geodesy points for the delineation of deforestation of the Mochovce site and for the detailed layout of rough ground grading. Later, a basic layout of control points was suggested that was gradually implemented in line with the progress of building work on the main site. The layout of foundations was done using the polar method and instrumentation by Kern. A rectangular layout micro-network was set out on the foundation slabs of the main production units to serve a detailed layout of the buildings. A large part of geodesy measurements is used as complementary measurements for producing the basic map of the plant. (E.J.). 3 figs

assumptions was included in work of Blok's disciple--Jewgienij Spektorski. An attempt of objective, free of emotions look at Błok's output to some extent makes us verify one-sidedly its critical estimate. In Błok's writings one can observe several earlier unnoticed values--author's wide mind horizons, his erudition, interesting but not accomplished research conceptions, competence for analysing difficult issues fringing upon social, political and philosophical thought.

Slovenske elektrarne (SE), a.s., Bratislava were, according to the time schedule of the previous government, expected to receive a new strategic co-owner this year. But this will not come true. Even though last year potential investors were invited to a tender and they even submitted their offers by the end of September but the new Privatisation Committee only started evaluating them in April. In the meantime a new Commission was established, the relevant Ministry prepared new plans and fights for chairs in SE's managing bodies were fought. A document containing privatisation alternatives for SE was sitting on the desk of Minister of Economy, Robert Nemcsics. The Coalition Board was busy discussing other topics and so, according to the Minister, SE should get on the agenda this week. R. Nemcsics claims that this privatisation requires political will as well. This political will will decide how the cabinet will handle an offer Czech CEZ submitted after deadline - in May this year - in a letter sent to privatisation agency National Property Fund (FNM). Spokesman of the Czech company, Ladislav Kriz explained that this step was motioned by signals from official and unofficial Slovak sources that CEZ could possibly be a suitable partner for SE. The whole debate about these two companies joining together was started at the beginning of this year by Vincent Pillar short after his sudden resignation from position of General Manager of SE. Production and export of electrical energy in years 1999-2002 is presented graphically
Programs ESTE EMO and ESTE EBO are emergency response systems that help the crisis staff of the NPP in assessing the source term (predicted possible release of radionuclides to the atmosphere ), in assessing the urgent protective measures and sectors under threat, in assessing real release (symptoms of release really detected and observed), in calculating radiological impacts of real release, averted or avertable doses, potential doses and doses during transport or evacuation on specified routes. Both systems serve as instruments in case of severe accident (DBA or BDBA) at NPP Mochovce or NPP Bohunice, accidents with threat of release of radioactivity to the atmosphere. Systems are implemented at emergency centre of Mochovce NPP and Bohunice NPP and connected online to the sources of technological and radiological data from the reactor, primary circuit, confinement, secondary circuit, ventilation stack, from the area of NPP (TDS 1) and from the emergency planning zone (TDS 11). Systems are connected online to the sources of meteorological data, too. (authors)

The paper presents general approach, used methods and form of documentation of the results that have been applied within the shutdown and low power PSA (SPSA) study for Mochovce NPP, Unit 1, Slovakia. The SPSA project was realized by VUJE Trnava Inc., Slovakia in 2001-2002 years. The Level 1 SPSA study for Mochovce NPP Unit 1 covers internal events as well as internal (fires, floods and heavy load drop) and external (aircraft crash, extreme meteorological conditions, seismic event and influence of surrounding industry) hazards. Mochovce NPP consists of two operating units equipped with VVER 440/V213 reactors safety upgraded before construction finishing and operation start. 87 safety measures based on VVER 440 operational experience and international mission insights were implemented to enhance its operational and nuclear safety. The SPSA relates to full power PSA (FPSA) as a continuation of the effort to create a harmonized level 1 PSA model for all operational modes of the plant with the goal to use it for further purposes as follows: Real Time Risk Monitor, Maintenance Optimization, Technical Specifications Optimization, Living PSA.

The nuclear power industry has been recently perceived by the general public as a specific industrial branch stretching its activities far beyond the conventional industrial standard. Similarly, the stage of testing and commissioning of a nuclear power plant is perceived as a specific stage in the plant life-cycle. This is a complicated process not only in technical terms, but in the context of nowadays, it is also one of the key periods in terms of public relations and public acceptance. The stage of commissioning unit 1 of Mochovce Nuclear Power Plant evoked a real communication media war between defenders and opponents of the nuclear industry started early in 1998 in Slovakia, as well as in other, mostly neighbouring countries. It should be noted, however, that the Mochovce plant has never been a technical problem as confirmed a number of international regulatory missions and audits, even though its construction was stopped in early 90's. The result of the war between the opponents and 'nuclear experts' was more or less clear to a thinking human being - a compromise could have been the only result. The compromise which is in fact a victory of the side of technical development, and loss of those lobbying for a nuclear-reactor-free central Europe. This article brings a review of events that accompanied commissioning activities of Mochovce NPP unit I which were important in terms of public relations

Analyses of external events had been first time performed at the design stage of the Mochovce NPP showing sufficiently low contribution of external hazards to core damage frequency. But, based on IAEA document 'Safety problems of WWER-440/213 NPPs and the categorization' (IAEA-EBP-WWER-03, 1996), the need of new reassessment arose due to discrepancy of some origin recommendations in compare with present IAEA ones. Mochovce NPP Nuclear Safety Improvements Program elaborated at the same time included the IAEA recommendations and following improvements were proposed to perform in context of external events. 1. Seismic project and new locality seismic evaluation This safety improvement includes also some 'on site' technical improvements in seismic stability of structures and equipment. 2. Unit specific analyses of extreme meteorologic conditions. This safety improvement focuses on impact of feasible extreme conditions on NPP systems caused by rain, snow and hail storms, frost, winds, low and high temperatures. 3. Analyses of external hazards caused by humans. In this safety improvement were specified: feasible sources of explosions; analyses of hydrogen, gas and propane-calor gas depots; air crash risk. The results of these implemented safety improvements were considered in the PSA study. The External hazards analysis is also part of Level 1 PSA Mochovce NPP performed by PSA Department of VUJE Trnava Inc., Engineering, Design and Research Organization, Slovakia. Some partial analyses are performed in cooperation with following companies DS and S - SAIC, USA and Geophysical Institute Academy of Science, Slovakia Relko, Slovakia. Basic documents are: NUREG/CR-2300 'PRA Procedures Guide - A Guide to the Performance of Probabilistic Risk Assessments for Nuclear Power Plants' and IAEA SS No. 50-P-7 'Treatment of External Hazards in PSA for NPPs. The external hazards analysis consists of following parts: 1. Geography and plant locality; 2. Nearby industry; 3. Extreme
The incorporation of the measurement of displacements of buildings in the construction documentation of the Mochovce nuclear power plant is dealt with. Each project design shows the points of ground control, the method of their stabilization, the intervals, accuracy and method of measurement, etc. Of great importance is the measurement of the turbine bearing frame, the turbine equipment, the main production units and the buildings of auxiliary operations handling radioactive material. The measured values of displacement were within the expected limits for all buildings. (E.J.)
The results are discussed of four years of investigating the technical and economic parameters of drilling and blasting equipment employed on the building site of the Mochovce nuclear power plant. The technical and operating characteristics are given of tested breaking and drilling sets manufactured by various foreign companies. The final choice was based on output, hard currency prices, power demand, operating reliability and number of personnel required for operation. The optimal set consists of two Hausherr HBM 70 drilling systems (holes with a diameter of 130 to 150 mm) and two ROC 601-02 Atlas Copco machines (auxiliary work, breaking foundation holes for nuclear reactors). (J.C.)

Full text: The Mochovce repository is a shallow land burial facility for disposal of low-level and intermediate-level radioactive wastes in the Slovak Republic. Waste generators include nuclear power plants, laboratories, hospitals, research institutes, and other radiological facilities. A performance assessment (PA) is required to determine the degree of potential risk posed to workers and the future public by these wastes, and to inform decisions about how that potential risk might be reduced. Since 1993, PAs of Mochovce have evolved as knowledge has improved, as computerbased analytical platforms have become more sophisticated, and as the repository has been upgraded to improve its operational capabilities and its long-term performance. The experience gained in this evolutionary modeling informs the current chain of deterministic one- and two-dimensional process models that constitute the bulk of the PA modeling. In order to evaluate the significance of different modeling techniques and of the uncertainty inherent in the parameters that are entered into such models, a probabilistic modeling framework has been developed using the GoldSim systems analysis computer program. In the new GoldSim model presented here, the essential behaviors of the process models are captured in simpler equivalent functions that are implemented in the GoldSim model. The uncertainty inherent in the imperfect state of knowledge about the repository's engineering, failure modes, the natural environment surrounding the repository, and the locations and behaviors of potential future human receptors is reflected in the definition of modeling parameters as stochastic variables. The new, integrated 'Mochovce repository GoldSim Model' is part of the evaluation of the facility. The model facilitates comparison of the repository's performance to regulatory dose limit objectives. In this new probabilistic implementation it can be used for other purposes as well. For example, analysis of the
The paper presents results of nuclear criticality safety analysis of spent fuel storage for the first and second unit of NPP Mochovce. The spent fuel storage pool (compact and reserve grid) was modeled using the Monte Carlo code MCNP5. Conservative approach was applied and calculation of keff values was performed for normal and various postulated emergency conditions in order to evaluate the final maximal keff values. The requirement of current safety regulations to ensure 5% subcriticality was met except one especially conservative case. (Authors)
The projects are described which were implemented by Doprastav Bratislava within the preparation of the site for the Mochovce nuclear power plant. This includes a railway siding in a length of 11.2 kilometres which includes a railway bridge, two other bridges and the reconstruction of the Kalna nad Vahom railway terminal. Also reconstructed or newly built were road communications in a total length of 23.3 km. The said project included the construction of a road flyover over the railway track and the construction of five other smaller bridges. In order to provide the utility water supply to the Mochovce nuclear power plant, a large reservoir is being built at Velke Kozmalovce. The reservoir will have a total capacity of 2.6 mill. m3 of water, of this the effective capacity will be 2.1 mill. m3 on a flooded area of some 90 ha.

JAVYS, the Nuclear Decommissioning Company owner and operator of National Radioactive Waste Repository (NRR) at Mochovce, is planning the enlargement of the existing NRR. The enlargement consists of the construction of new structures (double rows) like the ones existing for LILW and of the new facility for the disposal of Very Low Level Waste (VLLW). A VLLW disposal site is being planned in Mochovce where a LILW disposal site is already located. As a part of ongoing licensing process for this change in utilization of the NRR we have updated the already existing assessment of potential radiological impact to members of the public after closure of the site, both from the migration of leachate in groundwater from the site and from possible inadvertent intrusion into the site, including future residence on the material excavated for the construction of the road. The radionuclides from the ground water reach the biosphere through a spring flowing into the lake. It is conservatively assumed that individual in the critical group uses biosphere of the lake (for irrigations, fishing and recreation). In the case of unintentional intrusion into the repository, the exposed group consists of a small number of workers who excavate or examine repository materials. The assessment is based on preliminary conceptual design for VLLW module, estimation of future volumes for the different waste classes and their radiological inventories and considers some common aspects and potential interactions between both disposal systems, such as radiological criteria, critical group definition, institutional period, site environment, total activity inventory.

Benchmarking efforts in the fall of 2006 showed significant performance gaps in multiple measured processes between the Slovenske Elektrarne (SE) nuclear organization and the highest performing nuclear organizations in the world. While overall performance of the SE nuclear fleet was good and in the second quartile, when compared to the worldwide population of Pressurized Water Reactors (PWR), SE leadership set new goals to improve safety and operational performance to the first decile of the worldwide PWR Fleet. To meet these goals the SE nuclear team initiated a project to identify and implement the Best Practice nuclear processes in multiple areas. The benchmarking process identified the Standard Nuclear Performance Model (SNPM), used in the US nuclear fleet, as the industry best practice process model. The Slovenske Elektrarne nuclear management team used various change management techniques to clearly establish the case for organizational and process change within the nuclear organization. The project organization established by the SE nuclear management team relied heavily on functional line organization personnel to gain early acceptance of the project goals and methods thereby reducing organizational opposition to the significant organizational and process changes. The choice of a standardized process model used, all or in part, by approximately one third of the nuclear industry worldwide greatly facilitated the development and acceptance of the changes. Use of a nuclear proven templated software platform significantly reduced development and testing efforts for the resulting fully integrated solution. In the spring of 2007 SE set in motion a set of initiatives that has resulted in a significant redesign of most processes related to nuclear plant maintenance and continuous improvement. Significant organizational structure changes have been designed and implemented to align the organization to the SNPM processes and programs. The completion of the initial
SE/ENEL, on a voluntary basis, has prepared new EIA Study for the completion of Units 3 and 4 of Mochovce Nuclear Power Plant (MO34 NPP) according to International current practices and European Directives. The results of the analysis, according to SE/ENEL Environment and Corporate Social Responsibility policies, will be provided to local Communities and Public Authorities. The Environmental Impact Assessment is performed: - in compliance with appendix 11 of Slovak Act. No. 24/2006 'On the assessment of the effects on the environment and on the modification and enlargement of some laws'; - meeting the requirements of the Exhibit II 'Illustrative list of potential social and environmental issues to be addressed in the Social and Environmental Assessment documentation' as reported in the document 'Equator Principles' of 2006 July developed by the International Finance Corporation (IFC). The area of Mochovce NPP is situated in Central Europe in the south-western region of the Slovak Republic (SR) at the western border of the Levice district. The area lies in the south-western part of the Kozmalovske hills mainly in the Hron highlands. From the point of view of the terrestrial and administrative organization of the SR, Mochovce NPP is situated in the eastern part of the Nitra region, in the north-western part of the Levice district, close to the border with the Nitra and Zlate Moravce districts. Mochovce NPP is approx. 12 km from the district capital Levice, which is the largest town within a 20 km distance from the power plant. Initial site preparation began in August 1983. In April 1998 the first fuel was loaded into Unit 1 of Mochovce NPP. The operation started in August 1998. Unit 2 started operation in January 2000. The original Construction Permit No. Vyst. 2010/86 for MO 34 was issued by the District National Committee in Levice on the basis of the Land Planning Decisions on 12 November 1986. This Permit has been renewed firstly on 5 May 1997 by letter of the
This paper presents genesis of Level 1 PSA project preparation for all operational modes of Mochovce NPP unit 1 including the description of its' main objectives, scope and working method. The PSA study which includes full power (FPSA) as well as shutdown and low power conditions (SPSA) Level 1 PSA has to support the nuclear safety improvements of the unit.

Mochovce NPP consists of four reaktor units of WWER 440/V213 type and it is located in the south-middle part of Slovakia. At present units 1 and 2 are in operation. As these units represent the second generation of WWER reactor design, additional safety measures were implemented to enhance operational and nuclear safety according to the recommendations of international audits and operational experience from other simular units (such as Dukovany and Bohunice). These requirements result into a number of safety measures grouped according to their purpose to achieve recent international requirements on nuclear and operational safety. The paper presents the bases used for specification of safety measures including their grouping into comprehensive tasks covering different areas of safety goals as well as structural organization of project management including participating companies and work performance. Results are also given regarding the contribution of selected safety measures to reduction of total core damage frequency. (authors)

Observing the given deadlines of the construction of the Mochovce nuclear power plant and the required volumes of breaking to the total value of 6.2 million m3 of rock, the required output was derived for the 7th five year plan to the value of 200,000 m3 per month, i.e., 10,000 m3 per day and 700 m3 per hour. The basic task is to build a flat building site with an area of 2,300 by 700 m2 which requires the removal of a masiff of rocks rising to a height of 37 m, and by compacting the mined rock to build heaps to a height of 20 m. The rocks were disintegrated by blasting. Surface blasting was used for mining faces and ribs. POLONIT 2 or PERMON DAP 1 were mainly used for blasting (ammonium nitrate explosives). The Danubit 1 detonator was used in holes flooded with water. For drilling a combination was used of drilling machines HBM 70 Hausherr with a drilling diameter of 130 to 155 mm and Ingersol Rand ECM 350 with a drilling diameter of 80 mm. The compressors used are Atlas Copco XRHS 350 Dd and PTS 900 Dd. As the optimal combination of machines for the removal of disengaged material for the daily output of 15,000 m3 the combination was used of 6 excavators with a shovel volume of 2.5 m3 ORENSTEIN-KOPPEL RH 25 with 12 Kockum 445 trucks and 18 ORENSTEIN-KOPPEL RH 40 excavators with a shovel volume of 4 m3 and a total of 64 Caterpillar 769 C, Belaz 548 A, Tatra T 200 and T 138 S1 trucks. The planned targets are being fulfilled and the work performed up to now on the Mochovce site equals 2.5 million m3 of excavated and removed rock. (B.S.)
There were 14 contributions presented of the conference focused on the integrated quality management systems in completion EMO34. Contributions were focused both on theoretical problems from the project management area and on the applications in practice in management systems implementation in accordance with the standards: STN EN ISO 9001:2000, STN EN ISO 14 001:2005, and OHSAS 18 001:1999 at the completion of the Nuclear Power Plant Mochovce of units 3 and 4
In this paper author deals with privatization of Slovenske elektrarne (SE), a.s. Bratislava and their influence on economy of the Slovak Republic. Country made the first step in privatization in the case of SE at the beginning of 90's by transformation of state enterprise to a. s. with state dominant position (95.8% of stocks was held by Fond narodneho majetku (National Property Fund), the rest was divided between SPP, a.s. and Restitucny investicny fond (Restitution capital fund). In the next phase two newly founded separate a.s. TEKO, a.s. (Teplaren Kosice) and SEPS, a.s. (Slovenska elektrizacna prenosova sustava) were set aside from a.s. Government adopted two basic variants of sale of SE, a.s. stocks by resolution N. 700/2002. Possible variants of SE privatisation are discussed. Energy position of Slovak Republic in European context is relatively favourable in present time because production capacities exceed domestic consumption and part of energy (up to 600 MWh) is exported. Future of thermal power plants Novaky and Vojany is interrogative because of tightened ecological norms, besides Slovak Republic undertook to lay up both blocks of Bohunice NPP V1. Forecasts show that Slovak Republic will stop to be self-sufficient in electric power production about 2010. (Author)
The important aspect is testing if the nuclear energy in the Slovak Republic is due to obligatory rules acceptable and its operation is regulated by the state through the independent institution - The Nuclear Regulatory Authority of the Slovak Republic (UJD). UJD considers the whole area of public relations an essential component of its activity. UJD intends to serve the public true, systematic, qualified, understandable and independent information regarding nuclear safety of nuclear power plants, as well as regarding methods and results of UJD work. Generally, public information is considered as significant contribution to the creation of confidence into the regulatory work. The public relations are understood as attempts to establish, keep and improve UJD-s good relations to its neighbours through purposeful informing. An Information centre at the offices of UJD was built and opened in October 1995 with IAEA Director General as the first visitor. NPP Mochovee is an example of international co-operation in achieving internationally acceptable safety standards. Companies from France, Germany, USA, Russian Federation, Czech Republic and Slovakia and last, but not least also the IAEA participated significantly on increasing the safety level of this NPP. We have been fully aware of the importance of good communication with press, TV and radio broadcasting in this pre-operation and operation period about nuclear safety, nuclear standard and other nuclear aspects commissioning of the NPP Mochovce in the UJD. The information policy of the UJD was in this period focused on the preparation an actual press releases for general and specialised news- paper and national press agencies. Very important were the frequent presentations the requirement safety stages of the NPP Mochovce inIV and radio broadcasting by headquarters of the UJD. UJD as the state authority provides information related to its competence, namely information on safety of operation of nuclear installations

The contribution defines the way of management of safety and protection of health and protection against the fire during completion of units 3. and 4. in NPP Mochovce. The creation of the management of safety raised from the legal and other requirements applied in the civil activities and mainly from the requirements for coordination of safety on the site. The whole system is methodically managed through the 5 basic documents so-called 'Building rules': 1) Safety-technical conditions of performance in SE, Inc. Bratislava (project MO34); 2) MO34/1/MNA-003.00-02 the elaboration of the integrated safety plan; 3) MO34/1/NA-003.00-03 risks analyse; 4) PNM3460100 Integrated safety plan for completion of Units 3.and 4 in NPP Mochovce; 5) Project of construction organization. The system itself of the management of the safety prevention must by provided by the supplier in compliance with the standard OHSAS 18 001 and ISO 14001, and in compliance with the requirement of the builder applied in the technical specification for the contract. Most of necessary related documentation of Safety plan for the site is usually part of the documentation for quality management of contractor. Therefore it is necessary to put the reference in each chapter of the Safety plan for site and the standpoint how to apply it for the particular specific situation. The coordinator is mandatory to manage the prevention for the part of safety of specified site and to coordinate the activity of suppliers during the works tie in this way, that the each contractor shall meet the safety requirements given by safety plan and also to identify and to eliminate the risks menaced in the particular work places or the suppliers each other. The builder established its own control system and for this purpose he settled the data base so-called 'The system of corrective and precautionary activities'. The system registers in its data base all discrepancies determined during the regular controls of the head workers
During joint development and designing of the bubbling vacuum system (BVS) equipment for localization of under-loss of coolant accident (LOCA) consequences on NPPs with WWER 440/213, a large volume of experimental and calculational activities have been performed by VTI and SverdNIIchimmash for the substantiation of functionality of this system, and in particular, for bubbler-condenser (BC) design, as a part of BVS. However, not looking on broad introduction of BVS on 16-th NPP units with WWER 440/213, its functionality was subjected to a doubt from experts of different countries. Sequentially, that promoted issue of the IAEA, document and OECD document. Therefore, before commissioning of the NPP 'Mochovce' unit 1 it was decided to execute additional experimental and computational researches for Safety Analysis Report preparation. Within the framework of these BVS thermodynamic behavior researches, in particular the following problems were chosen: (1) The check of a capability of valves DN 250 blocking in an opened position, as a result of return pressure differential on BC, during vent clearing process of the hydro-lock, that can sequentially result in an a drop of efficiency of stem condensation in BC pool; (2) To provide by direct measurements the absence of pressure oscillations dangerous for strength of a BC design in different modes of steam condensation in BC and to execute computational researches of instability of steam condensation processes (for such mode as 'chugging'); (3) Study influences of pool swell and water carry over through check valves DN 500 in the air traps on a BVS functionality; (4) To determine by a computational way the maximum pressure in NPP premises during LOCA, with taking into consideration additional failures of the BC equipment: absence of a water on two and more BC plates and DN 250 valves have blocked in an opened position (conservative conditions).

In the first decade of June 2008, during the power commissioning of the reactor at the Mochovce NPP unit 1, the experiment with reducing the thermal power of core almost to the balance-of-plant (BOP) needs was performed. After the reactor has operated for seven hours at low power (about 200 220 MW (thermal)), its power was increased (at a rate of about 0.25% of Nnom/min) to the initial level, close to 107% (1471 MW). During the experiment, core parameters, which were subsequently used for comparing the measured data with the results of experiment simulation calculations, were recorded in the reactor in-core monitoring system database. Calculated and measured levels of critical concentrations of boric acid were compared, along with power density distributions by fuel elements and assemblies obtained both by the KRUIZ in-core monitoring system and on the basis of calculations simulating reactor operation in accordance with the given core power variation schedule. The final stage consisted of assessing the methodical component of power density micro- and macro-fields calculation error in the core of Mochovce-1 reactor operating with varying load. (author)
In this paper authors describe the experience gained during commissioning and trial operation of Mochovce NPP (EMO). The first year of EMO operation from the point of view of safety and reliability was successful. Evidently we were challenged with certain problems characteristic to this stage of operation which resulted in automatic reactor shutdown. There were 11 automatic shutdowns in 1998 by action of the quick emergency protection AO-1 and two manual shutdowns by the AO-1 key. In 1999, there were 6 automatic shutdowns by action of the quick emergency protection AO-1. Three of them was connected to the falsely activated binary signal of MCP switch of, in two cases the reason came out from the turbo-generator (TG) cooling water system. Very positive trend in the operation of both units shows the fact that during all commissioning period of the second unit there were only three automatic reactor shutdowns by the signal AO-1. All these actions were done in frame of commissioning tests. All causes which activated the automatic unit shutdowns were found out and rectified, the overall tuning of the cooling water system is on the process now. The solution of this problem is possible only power commissioning, and in the stage of the trial operation had no direct impacts on the nuclear, radiation, or technical safety respectively. In 1998 two events according to the INES scale after second unit commissioning because of two unit links of the cooling water system. The operational events during the commissioning tests, start-up tests, physical commissioning, were ranked the category 1 ('Action of SIS U040 ppo <8,34 MPa at the system 2 and 3' and 'Breaching the L and C'). In 1999 only events occurred that were ranked in the category safety insignificant events and lower (category 0, or off the scale respectively). In the frame of the safety culture principles adopted, such as critical attitude, exact and careful approach, and communication, these problems were given the
The Mochovce-Nuclear Power Plant is one of the WWER-440/213 plants which has been designed against earthquake. Nevertheless, the design earthquake has not been assessed adequately to the seismic hazard at the site. A new seismic design shall include an increased seismic input and assure an acceptable standard of safety. This contribution is related to some design aspects of civil structures for this nearly finished plant, such as: existing design and its margins with regard to the employed codes; requirements for a new design concept; effects to be expected by an increased design earthquake; applicable design methods; use of inelastic design spectra, behavior factors and capacity design; feasible upgrading measures.

In 1982 to 1983, the composition was studied of natural populations of yeasts and yeast-like microorganisms in the area of the construction of the nuclear power plant at Mochovce. Samples were taken from fruits of plum trees (Prunus domestica L.) and grape vine (Vitis vinifera L.). Totally, 394 strains were isolated that were identified and classified according to the monography of Lodder into the following families and genera: Saccharomycetaceae (Saccharomyces, Hanseniaspora, Hansenula, Debaryomyces, Kluyveromyces, Pichia), Spermopthoraceae (Metschnikowia), Cryptococaceae (Torulopsis, Candida, Kloeckera). On plum tree fruits the species Hanseniaspora uvarum and Saccharomyces rosei and on grape vine fruits Hanseniaspora uvarum and Metschnikowia pulcherrima were most abundantly represented. The trees and plants were not treated with pesticides and on both the fruits of plum trees and grape vines the species Pullularia pullulans was frequently present that had never been isolated before from regularly treated vineyards.

A comparison is given of ecological damage for the nuclear power plant in Mochovce and a conventional power plant with the same power. Ecological effects and damage are divided into three groups: comparable damage, ecological damage caused only by conventional power plants and ecological damage caused only by nuclear power plants. In the first group the factors compared are land requisition, consumption of utility water and air consumption. In the second group are enumerated losses of crops (cereals, sugar beet, potatoes, oleaginous plants) and losses caused by increased disease rate owing to polluted environment by conventional power plants. In the third group health hazards are assessed linked with ionizing radiation. Also considered are vent stack escapes. (E.S.)

In this paper the history of delivery of technological part for NPP V-1 Mochovce as well as of reconstruction and safety improvements by the Skoda Praha a.s. is presented. Primary contractor of technological part Skoda Praha together with its final suppliers proved ability to realize under hard conditions such a complicated work what was indisputedly Units 1 and 2 finishing. Company proved capability to conform itself flexibly in the course of work to requirements of customer for realization of safety measures which means that Units 1 and 2 fully satisfy international standards. By fulfilment of primary contractor of technology obligations and above all by takeover of complex responsibility for both Units putting in operation including responsibility for 'past' Skoda Praha put away one of basic problems which occurred in decision making to whom will be assigned construction finishing contract. These facts fully qualify Skoda Praha to be selected for possible Units 3 and 4 construction finishing as one of chief construction finishing participant

Enel will only answer the basic question whether Slovenske elektrarne will complete the reactors 3 and 4 in nuclear power plant in Mochovce next year. Initial analyses made by Enel indicate that the completion of Mochovce would cost over 60 billions Sk (1,54 billions EUR). Since National Property Fund has approved the strategic investment plan two more conditions have to be met before Enel can acquire Slovenske elektrarne. The first condition is that a part of the company assets has to taken over by state owned joint stock company GovCo. This regards reactor V-1 in nuclear power plant Jaslovske Bohunice that should be made ready for closure by end of 2008, damaged reactor A-1, nuclear equipment decommissioning and disposal unit VYZ and hydroelectric power plant in Gabcikovo. The other condition that still has to be fulfilled is passing of a new act on disposal of nuclear power generating equipment. The new act should distribute the fund's resources amongst the individual nuclear energy sources. M. Arcelli (regional manager of Enel for Slovakia) stresses that the money nuclear power station in Mochovce and V-2 earned and will earn during their time in operation will have to remain in the fund to cover their later liquidation i.e. should not be used on liquidation of reactors V-1 or A-1.

Since the 90-ies Slovenske elektrarne have been gradually improving the environmental aspects of their generation. At the thermal power plants of Novaky and Vojany they have developed the equipment for fl u-gas desulphurization and denitrification, replaced the old boilers by fluidized-bed boilers, and installed automatic monitoring systems. At Vojany they have increased the share of co-fi red wood-chips, and at this site and at Mochovce they have built two new photovoltaic power plants. Clean energy from the nuclear and renewable sources increased 85% in 2010. (author)
This year (2007) in March a reputable international agency GfK conducted a poll, which was focused primarily on the questions relating to the presence and future of nuclear energy sector in Slovakia as well as brand awareness of Slovenske elektrarne. It results from the poll that 2/3 of Slovak population is not against the completion of Units 3 and 4 of Mochovce NPP (EMO34), and this relates to as much as 87 % of the asked in the region within a 10 km distance from EMO!

Conditioned radioactive wastes from Jaslovske Bohunice NPP and from the decommissioning process of the A-1 NPP are deposited in the Republic disposal site of radioactive wastes in Mochovce since 2000 year. These wastes are transported nowadays by the roads. Slovenske elektrarne, a.s. (SE) are implementing new model of transport of dangerous expenditures. During 2005 radioactive wastes open to transport not only by the Slovak roads but by railway too. For needs of transport three special wagons and 12 transport-operating frames were manufactured, which will serve for fixation during all transport cycle. Within one transport 12 containers will be transported by the same mail. At the transhipment station in Mochovce they will be reloaded on the lorry-trailer combination, which will transport them by the road to the object of the disposal site
After transformation of filial companies of Slovenske elektrarne (SE) a.s, Bratislava to separate enterprises, a change of its managers also arose to 1 August. The changes were announced by executive chairman and general manager of SE Miroslav Rapsik. Minister of economy Robert Nemcsics has not participated in companies manager selection. Robert Gunis was named as Bohunice NPP manager, Jaroslav Holubec was named as Mochovce NPP, Eduard Seboek was named as Novaky thermal power plant. Martin Slezak is chief of imposition company, Milan Fedorco is manager of Vojany thermal power plant. Vladimir Majercak has remained manager of Trencin water power plant and Jozef Guba has remained manager of uncompleted Mochovce 3-4 NPP
Final treatment of liquid radioactive wastes which are produced by 1st and 2nd bloc of the Mochovce NPP, prepares the NPP in its natural range. The purpose of the equipment is liquidation of wastes, which are formed at production. Wastes are warehoused in the building of active auxiliary plants in the present time, where are reservoirs in which they are deposited. Because they are already feeling and in 2006 year they should be filled definitely, it is necessary to treat them in that manner, so as they may be liquidated. Therefore the Board of directors of the Slovenske elektrarne has disposed about construction of final treatment of liquid radioactive wastes in the Mochovce NPP. Because of transport the wastes have to be treated in the locality of power plant. Technically, the final treatment of the wastes will be interconnected with building of active operation by bridges. These bridges will transport the wastes for treatment into processing centre

The NPP's first document dealing with ageing management procedures and responsibilities was issued in 1996, hence, before any of the units was operable. The concept described in the document is highlighted in the article. The description encompasses the responsibility system, procedures to set up ageing management programmes for the various equipment items, and co-operation among the various departments in implementing the ageing management programmes. The Ageing Diagnosis and Management department has available both hardware and software to fulfil the ageing management programmes. (author)
A review of the construction and operation of nuclear power plants in Slovak Republic which belong within Slovenske Elektrarne is made. Since 1993 with the applying of the Least Cost Planning Methods and Financial Feasibility Analysis the optimal variant, considering construction completion of the two units at Mochovce NPP, has been adopted and a project for safety enhancement has been implemented. Some changes have been made in siting project in order to meet the seismic requirements, following by change of the control system design and supplier. The most important result of the safety enhancement program, important not only for NPP Mochovce, but also for all NPPs of WWER 440/213 type, is the fact, that operability of containment with passive bubbler-condenser system for pressure suppression and its acceptability from safety point of view, has been fully confirmed. Results of safety enhancement program have been re-evaluated not only by International Atomic Energy Agency, but also by other international authorities and professional organisations with positive result. Especially significant is the conclusion of RISKAUDIT, which has carried out repeated evaluation of safety level of NPP Mochovce based on PHARE project and which is accepted by European Commission. A similar approach for enhancing the safety has been applied for the NPP V-1 units at Jaslovske Bohunice
The need to expand nuclear power and its advantages are discussed publicly nearly each week. According to politicians and the nuclear lobby investing tens of billions Sk at Mochovce will bring Slovakia the often cited 'independence and energy self-sufficiency'. It will also mean profit for Slovenske elektrarne and the company's shareholders - the state and Italian company, Enel. In addition to the lively discussion on the pros and cons of nuclear energy, TREND was also interested in the living conditions around the concrete and strictly guarded, potentially dangerous plants and in the opinion of the people most affected by Mochovce and Jaslovske Bohunice on expansion of the existing and the building of new nuclear power plants. The construction of nuclear powers stations in these regions was not only about new jobs. The state 'prescribed' iodine pills and did not allow any construction in the region and, in the case of Mochovce, ordered the complete demolition of a village. The only thing that remained from Mochovce village was the church. 'And when it was found that the power plant would not reach it, it was even given a new roof. Former inhabitants, especially the older ones that had problems accepting the evacuation, used to visit it often,' explained Jan Foldy, the head of the local municipality in Kalna nad Hronom. After many years, life in the neighbouring villages is not bad. Their budgets are overflowing and so they can afford to spoil their inhabitants with free cable TV and high standard sport facilities, which should partly compensate for the fact that the people are living so close to a nuclear facility.

Izkoriščanje sonca je v zadnjem času vedno bolj pogosto. Sonce, večni jedrski reaktor, je praktično neizčrpen vir obnovljive energije. Čist in donosen vir, ki nam lahko zagotovi pomemben del energije za naše potrebe. Energija, ki jo sonce seva na zemljo, je 15.000 krat večja od energije, kot jo porabi človek. To je energija, ki se obnavlja, ne onesnažuje okolja in je hkrati brezplačna. Zato, mora biti cilj izkoriščati to energijo v največjem možnem obsegu. Da bi sonce lahko čim boljše izkori...

This Environmental Report contains the results of the joint stock company Slovenske Elektrarne (SE) in relation to the natural environment primarily for the year 2003, but it also lets us compare results with preceding years. In 2003 Slovenske Elektrarne generated a total of 26,048 GWh of electricity. In terms of the market share in the Slovak Republic, this volume accounts for almost 84 % of electricity produced. Despite an extremely dry year, when outages in production of hydropower plants were 23 % more than planned, we managed to maintain the share of production from nuclear and hydroelectric power plants at a level in excess of 80 %. The outages in production at the hydro plants meant above all that we had to increase the output of thermal plants. Despite this fact, thanks to the ecologization of units we kept up the trend of progressively reducing the volume of production of basic pollutants, which is our long-term goal. This report contains the following headings: (1) Address by the Chairman of the SE Board; (2) Environmental Policy of join-stock company SE; (3) Atmospheric protection; (4) Water management; (5) Waste management; (6) Environmental management system in SE, a.s.; (7) Funding for environmental protection; (8) Bohunice Nuclear Power Plant SE-EBO; (9) Mochovce Nuclear Power Plant SE-EMO; (10) The Facility for decommissioning of nuclear facilities, radioactive waste and spent fuel management SE-VYZ; (11) Vojany Power Plant SE-EVO; (12) Novaky Power Plant SE-ENO; (13) Hydroelectric Power Plants SE-VE; (14) Units 3 and 4 of Mochovce Nuclear Power Plant SE-MO 34

Full Text Available Epidural volume extension (EVE is a modified form of combined spinal epidural with normal saline injected into the epidural space after the intrathecal dose. EVE techniques increases the level of sensory block resulting from the volume effects when the volume of fluid in the epidural space suppresses the dural sac and causes the cephalad spread of local anesthetic. The aim of this research was to assess differences in the effects of 5 mL EVE and 10 mL EVE by 0.9% saline with 10 mg 0.5% bupivacaine on sensory block height and motor block recovery in caesarean section patients. This research was carried out from mid September to November 2014 in Dr. Hasan Sadikin General Hospital Bandung. This was a randomized controlled clinical trial conducted on 30 patients who underwent caesarean section (SC and divided randomly into two groups, namely group receiving 10 mL EVE and group receiving 5 mL EVE with a spinal epidural combination anesthesia. The assessment of sensory block height was performed using the pinprick test while bromage score test were used for motor block recovery. The data was analyzed using t test. The results showed a faster recovery of motor block in the research subjects using 10 mL EVE compared to those using 5 mL EVE (p<0.001. The conclusion from this study is that the administration of 10 mL EVE in patients who underwent caesarean section leads to a faster motor block recovery with the same sensory block height.

A brief account of activities carried out by the Vyskumny ustav energetickych zariadeni, a.s. (VUEZ) in 2006 is presented. These activities are reported under the headings: (1) Introductory address by the Chairman of the Board of Directors; (2) Company profile; (3) Organisational structure; (4) Portfolio of products and services in 2006; (5) Quality management system; (6) Human resources; (7) Financial statements and auditor's report; (8) Auditor's certificate; (9) Basic and contact data. The year 2006 was a year of changes in the Slovak energy sector what, in a certain degree, became evident also in the related sphere of supplies. In the course of the year, Slovenske elektrarne a.s. Company was divided into two entities and its proprietary structure was changed. At the same time, the number of capital investment projects was reduced and the related procedure of procurement was changed. VUEZ, as a supplier to the energy sector, had to promptly respond to the changes. That was why in the first half of 2006, the organisational structure of VUEZ was modified. In the course of the year, also the structure of customers on the domestic market was partly changed. To stable partners such as Slovenske elektrarne (and its successors after the company splitting), another important partner was added - Vodohospodarska vystavba s.p. Bratislava. As to Slovenske elektrarne, our supplies were oriented mainly on nuclear reactor units in the Jaslovske Bohunice and Mochovce NPPs. At the end of the year, a joint convention was agreed and concluded on application of the results of the joint research at third parties. In the preparation for the decommissioning of the Jaslovske Bohunice V1 NPP, VUEZ continued its participation in on-going projects of an international consortium of companies. Similarly important were the customers such as CEZ a.s., Czech Republic (in particular its Dukovany NPP), and the Paks NPP (Hungary)
The degradation of reactor pressure vessel (RPV) steel is a complex process depending on many factors (thermal and radiation treatment, chemical compositions, preparing conditions, ageing, operation environment, etc.). This paper describes tests based on Nondestructive Methods used for evaluation of material characterisation at Slovenske Elektrarne a.s. Positron Annihilation Spectroscopy (PAS), Moessbauer Spectroscopy (MS) and Transmission Electron Microscopy (TEM) investigate microstructure changes of Reactor Pressure Vessel steels caused neutrons irradiation. There are showed results of investigation of reactor pressure vessel steel specimens after five years irradiation in reactor nature by mentioned NDT methods. Investigated specimens has been prepared for the Extended surveillance specimen program which has run out on the 3rd and 4th units of NPP Jaslovske Bohunice and for the Modified surveillance specimen program in the 1st and 2nd unit which is continued in NPP Mochovce (Slovakia). PAS and MS spectra showed that the degradation of the steel properties associated with the effects of neutron irradiation can be well detected. The samples from RPV base metal (15Kh2MFA) and weld metal (Sv 10KhMFT) were measured by PAS and MS before and after irradiation. Samples have been irradiated in VVER-440 reactor (units 3rd and 4th in Bohunice as well as 1st and 2nd units Mochovce) by neutron fluency from 7.8 1023 m-2 up to 2.5 1024 m-2. Measurement results are presented and discussed in detail.(author)
The purpose of this report is to describe the re-starting phase of DNPP MO 34 Project, mainly focusing on management issues. The report consists of three main parts dealing with the Project management organization during the three different periods of the of DNPP re-starting process. The first part (Chapter 2) begins with the general background information about the NPP and then focuses on the pre-feasibility and feasibility study. The second part (chapter 3) deals with the current status of the plant and it stresses the main steps of the DNPP Project resuming after completion of the feasibility study. The third part (Chapter 4) outlines the main issues related to the criticality of a typical DNPP Project (e.g. preservation and maintenance of equipments, updating to technological and regulatory requirements, human resources, protection of design documentation, etc.) and the measures implemented in MO 34. The hereby presented content reflects the experience and good practices concerning the following main management issues: - project control measures; - human resources; - preservation and maintenance of site installations, structures and equipment; - updating of the whole Project to meet licensing requirements and technology upgrades; - preservation of Project documentation.

Described is the common project for completion of bubbler condenser qualification for nuclear power plants in Bohunice, Mochovice, Dukovany and Paks. Functionality of the bubbler condenser was elaborated during the simulation of the main steam line brake, medium break and small break LOCA. On this basis the appropriate operation of bubbler condenser containment under accident conditions can be positively confirmed
A major element of providing information is the demonstration that the area of nuclear energy uses has its binding rules in the Slovak Republic and the observance thereof is controlled by the state through an independent institution Slovak Nuclear Regulatory Authority (UJD). As early as 1995 were laid on the UJD the foundations of the concept of broadly keeping the public informed on UJD activity and the safety of nuclear installations by opening the UJD Information Centre that provides by its activity communications with the public and mass media, which is instrumental in creating in the public a favourable picture of the independent state nuclear regulation. Clear communication policy is the key to credibility and is based on perceptions which give ride to varying levels of confidence. It has been consistently found in opinion research that credibility is the single most powerful persuasive force. Public communication programmes are the principal currency for the Regulatory Authority to inform the public on issues like costs, benefit requirements and risks
Bubbler condenser strength behavior at maximum pressure difference possible under-loss of coolant accident (LOCA) conditions was evaluate. The results and observations of static testing: static overpressure was gradually increased until the stipulated maximum of 30 kPa was reached; plastic deformations of the walls include ribs; plastic hinges at mid height of the side wall stiffeners; deformation of bottom and ceiling sheet remained elastic; functional capability of BC remained preserved. It was concluded: an overpressure of 20 kPa is adequate for the structural evaluation at the initial phase of the accident; low frequency pulsation effects during condensation have amplitudes less than or equal to 5 kPa; relevant swell or chugging effects have not been observed. Conclusions for upgrading: sheet structures of the tray chambers in the regular floors (1st to 11th floor) are evidently capable to resist an overpressure of 20 kPa without a reinforcement; functional capability remained preserved under a static overpressure of 30 kPa in the experimental verification; a similar strength capacity of the tray chamber on the 12th floor has not been demonstrated by analysis and could not be verified by experiment; a sufficient functionality of BC is preserved even when this way tray level would fail. The global stability of the storey remains preserved. A reinforced of the sheet construction is not proposed; main floor beams located under the side walls shall be upgraded. Spacers with screw jack shall be inserted between the tray wall elements at the bottom of BC in the 2nd to 11th floor, and between the interrupted ceiling ribs in the 1st to 10th floor. Main floor beams under the side walls in the 1st to 11th floor will be upgraded using existing beams and new or modified anchorage; beams in the bottom floor shall be protected from uplift. Struts installed between the beams of the 1st and 2nd floor are designed for
V današnjem času si je skoraj nemogoče predstavljati naš vsakdan brez potrebe po rabi električne energije. Ljudje iz dneva v dan postajamo vse večji porabniki električne energije, s tem pa se posledično povečujejo potrebe po dodatni proizvodnji električne energije. Da se s povečanjem potreb ne poveča obremenjevanje okolja pri proizvodnji elektrike s pomočjo termoelektrarn, so obnovljivi viri energije (OVE) prava pot za prihodnost. Prav tako cene fosilnih goriv strmo naraščajo in prekomerna po...
This Environmental Report contains the results of the joint stock company Slovenske Elektrarne in relation to the natural environment primarily for the year 2003, but it also lets us compare results with preceding years. In 2003 Slovenske Elektrarne generated a total of 26,048 GWh of electricity. In terms of the market share in the Slovak Republic, this volume accounts for almost 84 % of electricity produced. Despite an extremely dry year, when outages in production of hydropower plants were 23 % more than planned, we managed to maintain the share of production from nuclear and hydroelectric power plants at a level in excess of 80 %. The outages in production at the hydro plants meant above all that we had to increase the output of thermal plants. Despite this fact, thanks to the ecologisation of units we kept up the trend of progressively reducing the volume of production of basic pollutants, which is our long-term goal. I would just like to point out some of the key events of 2003 with regard to the environment. In the preceding year, the Mochovce nuclear power plant was first to be awarded the environmental management system certificate in line with ISO 14001:1996. We progressed in 2003 and managed to successfully pass the certification process also for Novaky thermal power plant and Bohunice nuclear power plant, with this process also being started in the group of hydroelectric power plants. Another significant achievement in 2003 concerned the results regarding emissions of pollutants at Vojany power plant. After extensive investments into the ecologisation of SE-EVO, emissions of SO2 are now just 3 %, emissions of dust pollutants 23 %, and emissions of NOx 24% - in comparison with the year 1980.

The Environmental Report for 2002 of the Slovak Electric, plc (Slovenske elektrarne, a.s.) is intended to provide information on the results achieved regarding the protection and creation of the environment over the course of the year and continue the communication process. A significant process, which began at SE, a. s., in 1998, was the construction and implementation of an environmental management system in accordance with the ISO 14 001:1996 standard. From August to September 2002, a pre-certification audit and certification audit was successfully undertaken at Mochovce nuclear power plant, and the certificate was awarded at a ceremony held on 11. 12. 2002 in Levice. The company plans that in the period 2003 to 2004 all the branch plants of SE, a. s., will undergo the certification process. After Mochovce nuclear power plant obtained the certificate the environmental management system became part of the overall management system. In accordance with our stated long-term and short-term environmental goals, the company is gradually redirecting its focus from atmospheric protection to water protection. Last year, a significant investment project in this area was the ecologisation of the external substation at the SE-VYZ branch plant. The main benefit of this project was a significant reduction of the risk of the contamination of the soil and groundwater by oil-based substances. At Vojany power plant, the test operation of units 5 and 6 of EVO I with an output of 2 x 110 MWe continued in 2002. These units were upgraded in past years to use the more environmentally friendly fluidized-bed combustion of semi-anthracite black coal. Thanks to their satisfactory test operation, the production of SO2 at SE-EVO fell to the lowest level in the plant's history - 6 041 tons, which represents a reduction in comparison with 2001 by 40 %.

A brief account of activities carried out by the Vyskumny ustav energetickych zariadeni, a.s. (VUEZ) in 2008 is presented. These activities are reported under the headings: (1) Introductory address by the Chairman of the Board of Directors; (2) Company profile; (3) Portfolio of products and service 2007; (4) Quality management system; (5) Organisational Structure; (6) Human resources; (7) Financial statements and auditor's report; (8) Basic and contact data; (9) Contact data. The year 2007 was arduous and, with regard to contracts and projects performed and related profits, also successful for VUEZ, a.s. On the domestic market, our principal customers have bee companies such as Slovenske elektrarne - Enel, Bratislava, in its locations of Jaslovske Bohunice and Mochovce, Jadrova vyradovacia spolocnost, Jaslovske Bohunice, and Vodohospodarska vystavba, Bratislava. Equally important customers for our company have been operators of foreign nuclear power plants, namely CEZ, a.s. (Czech Republic) and the Paks NPP (Hungary). In the course of 2007, negotiations and offer proceedings were initiated with WWER nuclear power plants in Ukraine and Russia
The specifications are presented of the cooling tower and the calculation is described of the permissible geometric shape deviation. The polar method was used in laying out the cooling tower and the process was based on the local layout network. The least squares method was used in calculating and aligning the coordinates. Digital theodolites were used in measuring the profile. The instruments allowed automating the collection and processing of the measured data. (E.J.)
The following major requirements and criteria fulfillment concerned the super-emergency feedwater system (SEFW) system were proposed: to provide sufficient water amount for accident conditions, inclusive seismicity, even during required SEFW system operation for the time period of 72 hours; to analyse ensuring of residual heat removal in case of a station black-out; to state criteria for water supply by the SEFW system into the steam generators (SGs); to simplify the existing connection scheme inclusive decreasing the number of valves, which are in series; to analyse and provide the system protection against a common cause failure, which the SEFW system did not provide in some parts (possibilities of three systems failure due to flooding; vulnerability of all tanks by the operation building fall in case of a seismic event; vulnerability of all tanks due to extreme climatic conditions; vulnerability of all tanks during new seismic loading and consequent mutual endangering; the possibility of three systems failure due to common routing in the vicinity of high; energy media on the +14,7 m floor in the intermediate machinery building and due to inconsistent electrical valves secured power supply systems); to analyse temperature increase impact on the number of uses and lifetime of SGs; to perform a change of SEFW system pipelines routing layout outside the dangerous area of the +14,7 m floor in the intermediate machinery building with high energy media; checking the thanks autonomy. There were performed analyses of selected transient operation modes. The analyses had the following objectives: necessary flowrate of the SEFW in case of the primary side stabilised temperature of 140 C till 72 hours of the process duration; sufficient capacity of one subsystem for the supply of sufficient water amount; sufficient water reserve in the tanks at given conditions; and other. Accident situations were evaluated using an analysis and three characteristic operation modes were selected, out of them each covers a group of ana-logical processes: operating mode with feedwater loss; operating mode with station black-out; operating mode during an earthquake
After the earthquake and subsequent tsunami in March 2011 Fukushima nuclear power reactors in Japan were damaged. As a result of damage of reactors escaped into air iodine radioactive isotopes which were dispersed by air masses over Europe and Slovakia. Isotope I-131 was identified in samples of the atmosphere and the abstraction of Radiation Control SE EBO. The air from the atmosphere contaminated with isotopes of iodine from the Fukushima ventilation systems that do not contain iodine filters, sucked into the interior of the controlled area, then released in organised way and then measured in the ventilation chimneys of EBO NPP. The measured values thus entered a balance of radioactive discharges. Drain of I-131 from SE EBO was in that period plus a contribution coming from Fukushima NPP and measured activity I-131 had to be corrected.
The lawyers of Enel will be spending the pre-Christmas period studying the transaction documents relating to the privatization of a 66% stake in Slovenske elektrarne, a.s. (Slovak Electric). At the beginning of the year, the Italian company Enel is set to sign the document that Cabinet approved in December 2004. Neither the draft privatization documents, nor the version approved by Parliament are publicly available. The Ministry promised to publish them after Enel signed the contracts. But Cabinet-level discussions prior to the approval of the documents uncovered problematic parts of the agreements related to the relationship between Enel, Slovak Electric and the state. Lawyers are examining the changes that were implemented based on recommendations of Cabinet members during the period after the postponement of the signing of the contract. Minister Pavol Rusko does not expect that Enel will reject the approved conditions, as that would mean the end of negotiations. But despite this, TREND asked whether he had an alternative plan prepared for such an eventuality. The Minister repeated that he had no doubt that the sale would be completed successfully and as of June Enel would become the new majority shareholder of Slovak Electric. He believes the 'the contract, which was very thoroughly prepared, will be very acceptable for both the selling and purchasing parties'. However, both the lawyers of Enel and the Minister should be aware of new facts they cannot be found in the privatisation documentation. And this is good news for both parties. This week Slovak Electric completed the process of financial restructuring and fulfilled the 'stabilization scenario'. Debt repayment has been postponed, debts will be repayable under standard conditions and will reflect the current capacity of the loan market. State guarantees have been decreased to a minimum and Slovak Electric will be able to request a new rating. More good news, mainly for P. Rusko, although he has not spoken
Slovenske elektrarne (SE), a.s, Bratislava in present time operates some sources, which would be off at normal conditions. It was caused by high electricity price on European markets. It is possible to sell 1 MWh for 12 thousands Slovak crowns abroad in last months. It is also advantageous to initialise thermal sources for power plant, where variable expenses are higher - from 1200 to 1300 Slovak crowns per MWh. SE are mainly trying to sell most of electricity on domestic market because returnability of dominant nuclear power plants was projected for this market. Utilizing capacities profit via domestic market covers fixed costs of power plants. Besides, power plant can demand regulated price 1272 Slovak crowns per 1 MWh. SE sources have capacity of 6800 MW, but maximal daily load uses for example in December approximately 4000 MW. Overflows are more higher in the summer - load dropped to 2200 MW in the beginning of September in last year. It is noted in issue that price increase in Europe is noticed. Price of primary power electricity will remain at liquid markets at 28 Euro (1176 Slovak crowns) in the following year prices fluctuate from 38 to 40 Euro (to 1700 Slovak crowns) per 1 MW at load peaks. Price increase is caused by lack of sources - it does not keep up to satisfy demand increase. Sources are gradually laid up and no new sources are built. Production capacities will decrease also in SE - by laying up of two 440 MW blocks of Bohunice NPP V-1. Price increase trend will continue according to SE businessmen till it is advantageous to build new source. Present price trend can be accelerated by decision about completing of Mochovce NPP 3-4
A brief account of activities carried out by the Vyskumny ustav energetickych zariadeni, a.s. (VUEZ) in 2003 is presented. These activities are reported under the headings: (1) Introductory address by the Chairman of the Board of Directors; (2) Mission and vision; (3) Basic data; (4) Product portfolio and customer services; (5) VUEZ - Quality mark; (6) Economic data; (7) Auditor's certificate; (8) Contact persons and addresses. In 2003, a number of important events took place in VUEZ. From the standpoint of international activities, a significant event was VUEZ involvement in the process or the preparation for the V-1 NPP decommissioning. VUEZ company became a subcontractor to the Consultant to the Project Management Unit who is an international Consortium consisting of Iberdrola Ingenieria Y Consultoria S.A., Electricite de France, Empresarios Agrupados Intemacional S.A. and Soluziona Ingenierfa S.A. In the field of experimental research, activities within the research and development project with IRSN Paris were successfully continuing. As to increasing the leak-tightness of NPP hermetic compartments, relevant works were executed at the Dukovany and Paks NPPs. For a business partner from Hungary, a project was initiated related to the manufacture and delivery of air locks. Predominant VUEZ capacities concentrated on Slovenske elektrarne, a.s. (SE) a.s. Company in the Jaslovske Bohunice and Mochovce sites. In addition to major sealing works and periodical integrated leakage rate tests at individual reactor units, VUEZ participated also in the upgrading of the V-2 NPP. Design work was implemented through ADVING, a daughter company of VUEZ; erection and installation works within the project were performed by relevant VUEZ departments during refuelling outages at the V-2 NPP
Slovenske elektrarne, a. s. (SE) entered the year 2008 with a determination to achieve the best possible profit from power production. During the process of production optimization were taken into account external conditions, which were mentioned in the last issue. The result is SE supply reaching 22 251 GWh. Very satisfactory for us is the fact that high fulfillments by nuclear power plants have exceeded the expectations. Bohunice V1 NPP up to 103%, Bohunice V2 NPP up to 104,5% and Mochovce NPP up to 102, 9%. Nonfulfillment of hydroelectric and thermal power plants is a result of objective reasons- as for thermal power plants due to market conditions and in case of hydroelectric power plants this has been a result of hydrological reasons. Just a few words to a crisis that appeared in January 2009. When we look back, we have to divide the issue into two periods (crises). The first one is an economic crisis the consequences of which were apparent already in December, where the providers of supporting services among industrial customers were unable to guarantee those services (the service is activated by reduction of consumption and since then there was no sale of their products, they cut off their production, i.e. power production, and as a consequence, no reserve for Ss remained.) Missing supporting services have been purchased by a transmission system provider on both daily and monthly basis. There was a demand for SRV, TRV30MIN, + TRV3MIN+, however, there were no extreme values. (author)

This is the tenth Environmental Report we have been regularly issuing annually since 1996 in order to give you information about our efforts and activities taken in the environmental protection area and, at the same time, to keep the mutual dialogue on a standard high level. The year 2005 was not easy for Slovenske elektrarne, a.s. Our company was subject to complicated internal changes to implement as effective company management model as possible. We strove, above all, to enhance the process management system that had already been developed previously. It is true that we also had to resolve personnel matters when looking for an effective power engineering company management model and we had to part from many of our colleagues during that stage. The second priority task we faced was to make preparations for the takeover of our company by the Italian company ENEL, S.p.A., and to complete the privatization process covering 66 % of Slovenske elektrarne, a.s., stock. It was especially the second half of 2005 that brought very intensive mutual discussions and working negotiations held on all management levels. The third, but not less significant, task consisted in detaching the assets which would not be covered by the privatization, namely to detach the Set of Gabcikovo Hydro Power Plants, to detach the VYZ - Decommissioning of Nuclear Installations, Radioactive Treatment and Spent Fuel Management Plant and the EBO V-1 Plant. Despite relatively complicated conditions and the opened and liberalized market in the Slovak Republic, our company produced 26,470,901 MWh of electricity whereby the target was met to 115.00 %. Our company kept the stability of the electric power supply system of the Slovak Republic, despite a complicated situation in the area of electric power supplies in Europe. We can really state that we produced in a safe, reliable, ecological and economical manner. The reliable operations of nuclear power plants in Jaslovske Bohunice and Mochovce where 17

The participants at the Conference called on decision makers both in the European Union (EU) and in Slovakia to provide fair treatment to nuclear power compared with other energy sources, especially with renewable, without prejudice to nuclear safety. This implies ensuring equality in terms of economics, tax, and accounting for externalities. The participants called on the Slovak government to initiate studies that compare the full life-cycle costs, impacts and risks, across the spectrum of energy sources and uses. They should also internalize the external costs. The participants called for a debate on the Slovak energy needs, taking into account the environmental impact of all potential sources of energy and the costs of providing electricity from those sources, and in addition a rational and objective analysis of the security of supply of those sources. It is necessary to have a range of sources for electricity generation that are cost effective and reliable, and respect the environment. The Slovak economy cannot withstand a sudden loss of its guaranteed energy supply. The participants believe that the major government role is setting overall policy for the economy, energy and the environment, with an adequate base in legislation and institutional competence. The Slovak government should have clear strategies for achieving self-sufficient energy-policy goals with reserve power and for meeting climate-change and air-quality goals. The Conference concluded that the nuclear option should remain open in Slovakia, as part of a balanced energy mix, in line with developments abroad and the EU Green Paper from 2000; the alternative is Slovak's failure to secure an affordable energy supply for its citizens. The participants supported the completion of Mochovce 3, 4, complying with enhanced safety requirements, as the most effective option. In Slovenske elektrarne, a.s.

Striving for energy efficiency means trying to obtain a certain result with a minimum of input (Schipper and Meyers, 1992; Blok, 2007). As energy is used to fulfil human needs, one may define the energy efficiency of an activity as the degree to which given human needs can be fulfilled with a minimu
Increasing efficiency, continuous improvement, ambitious investment plans. How we (Slovenske elektrarne) succeeded in overcoming crisis impacts and achieved excellent results, about the necessity to increase the company's safety culture - these issues were discussed at the Goal Setting Meeting 2010. The introductory meeting was held on 9 March 2010 in Bratislava. (author)

Instalment payments in this and the coming two years amount to 32 billion Sk (762.8 mn Euro) - that is about 60 percent of the overall credit burden of the electricity producer Slovenske elektrarne (SE). And so the situation from three years ago is repeating itself - a new financial department of the company is expected to lead the company out of the substantial cash-flow crisis caused by credit burden. This difficulties have been caused by decisions taken by state like building of power plant in Mochovce. Minister Nemcsics will not be in the position to complete his ambition to direct the activities of SE, his successor will need time to find his way and so the solution stays in hands of the company management. Where will they look for the necessary recourses? The operation generates virtually no cash-flow increase - reminds General Manager for Economy and Finances, Milos Sujansky. What the manager considers a possible solution is loan restructuring. 'We have to review the whole loan portfolio in order to eliminate the pressure caused by the necessity to repay the debts in 2004 and the beginning of 2005 and that would allow as to survive in a relatively normal state,' unveils the company plans M. Sujansky. That would mean postponing the instalment payments until 2007. Before this strategy was prepared the existing debts had to be analysed. The results of this analysis showed 'an inconsistent debt portfolio with many non-standard elements anchored in relevant contracts'. In the opinion of Director for External Financing this fact makes the loan management and decision making in regards to assets/liabilities structure difficult. 'When you have 35 different loans and every contract is different - communication and monitoring costs much effort,' he adds. According to an Auditors Report for 2002 prepared according to ISA standards even the share of third-party capital is high and inhomogeneous. The previous financial management managed to minimize the deficit. The fact
A brief overview is given of the power sources in Slovakia which include 6 operational reactor units (4 at Jaslovske Bohunice and 2 at Mochovce) and 2 units under construction (at Mochovce). The efforts undertaken in the past 10 years and aimed at upgrading the nuclear safety of the two older (V-230 Soviet type) units at Bohunice are highlighted. The relevant regulatory decisions are dealt with and the measures already carried out are listed. Also characterized are several IAEA international safety assessment missions and safety-aimed meetings which took place in 1998 and 1999 and are of concern to the older Bohunice units. (A.K.)

To evaluate, in a confirmatory fashion, whether baseline and change from baseline to 24-month follow-up in cartilage damage, bone marrow lesions and meniscal damage are predictors of knee replacement (KR) in subjects with a high risk of osteoarthritis (OA), independent of the level of physical activity, symptom severity and radiographic abnormalities. Data from the Osteoarthritis Initiative's (OAI) baseline and 24-month follow-up knee MRIs of 115 patients (age range: 45-78 years; 48 % female; BMI: 20.9-48.7) were analyzed. Cartilage, bone marrow and menisci were semi-quantitatively scored according to the Whole-Organ Magnetic Resonance Imaging Score (WORMS) and Boston-Leeds Osteoarthritis Knee Score (BLOKS) systems in all compartments. Baseline and 24-month interval changes in structural tissue damage assessed by BLOKS and WORMS were used as predictors of KR independent of clinical and radiographic parameters using Cox hazard analysis. Adjustments were performed for age, gender, BMI and physical activity (Physical Activity Scale for the Elderly: PASE), Western Ontario and McMaster Questionnaire (WOMAC) total score and radiographic Kellgren-Lawrence (KL) score. BLOKS and WORMS baseline cartilage scores were predictors of KR independent of the PASE, WOMAC and KL score. One score increase in the average baseline BLOKS full-thickness cartilage defect score was associated with a [hazard ratio (95 % CI)] 13.55 (3.61-50.89) times greater risk of KR independent of the PASE, WOMAC and KL score. Net reclassification improvements (NRIs) of the additional evaluation of 24-month follow-up MRI scores and assessment of changes were not significant for prediction of KR (NRI range: - 7.23 - 24.8 %). The BLOKS cartilage score for full-thickness cartilage defects had the highest hazard for KR. Follow-up MRI changes in structural tissue damage, detected by BLOKS and WORMS cartilage, bone marrow or meniscus scores (up to 24 months) had no significant predictive value in addition

In the 'Block by Block' project 13 local energy saving projects are supported in the development of concepts to realize large-scale energetic improvements of existing houses. In these projects the consortia develop strategies which are applied in the market. In addition, a number of projects is awarded with a so-called 'Green Deal' (agreements between governmental, public and private parties in the Netherlands). Part of the support is a knowledge and learning process. As part of the learning process a practice-oriented research has been carried out into the possibilities of database marketing (DBM) for energy conservation. The research focuses on the opportunities for DBM for energy savings and promising product-market combinations. The question is: can DBM contribute to improving the effectiveness of the 'Block by Block' projects? [Dutch] In het project 'Blok voor Blok' worden 13 lokale energiebesparingsprojecten gesteund bij de ontwikkeling van concepten ten behoeve van de grootschalige energetische verbetering van bestaande woningen.
