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 hermetic compartments of VVER 440 NPPs fulfil the function of the containment used at NPPs all over the word. The purpose of the containment is to protect the NPP personal against radioactive impact as well as to prevent radioactive leakage to the environment during a lost of coolant accident. Leak-tightness enhancement in NPPs with VVER 440/213 and VVER 440/230 reactors is an important safety issue. New procedures, measures and methods were adopted at NPPs in Mochovce, J. Bohunice, Dukovany and Paks for leak identification and sealing works performed by VUEZ Levice. (authors)

The main reason for penetration of undesirable admixtures from cooling water in the condensate is the inleakage of steam turbine condensers. Briefly assessed are the means and methods of detecting and locating condenser leaks used in the world and in power facilities in Czechoslovakia. Equipment was developed based on measuring the difference between the pressure in a temporarily closed condenser tube and ambient pressure, for leak testing of condenser tubes during operation and during shutdown of WWER-440 units. Two types of the equipment were tested in practice. Type VUEZ-PHN 85P meets the requirements of objective leak tests and those of leak location in condenser tubes and of leak detection in tube expansion in the tube plates of WWER-440 unit condensers, this as concerns sensitivity, the objectivity of results, the cost of tests, and minimal losses of power during the test. Type VUEZ-PHN 85P can be used for leak location in all tube type heat exchangers with access to tube outlets in which under- or overpressure can be achieved in the space between the tubes relative to ambient pressure during the test.

The 'Institut de Radioprotection et de Surete Nucleaire' has decided to perform an experimental program of studies on the risk of sump plugging in a 900 MWe pressurized water reactor (PWR). A general overview of the literature has been conducted between October 1999 and November 2000, ending by the definition of an approach methodology and the written of technical specifications. The problem identified gave rise to an European call for tenders leading to four contracts signed in november 2001. Three contracts are managed by VUEZ (Slovakia), the last by EREC (Russia). The methodology and the facilities devoted to these studies are presented in this paper, the preliminary results observed are also presented. The objectives for 2003 to finalize the program and the safety assessment are presented. (authors)
In this paper the interview with engineer Peter Hlbocky, director of division of the Project of decommissioning of V 1 Nuclear Power Plant in Jaslovske Bohunice is presented. Project Manager Unit (PMU) was formed on the basis of directive of the General Director of the Slovenske elektrarne, a.s. The Director of the Division of decommissioning of the V 1 NPP and at the same time the Main manager of the PMU is engineer Peter Hlbocky. On this project participate 19 employees of the Slovenske elektrarne, a. s. (SE), 6 abroad employees of the consortium IBERINCO, 15 employees of the VUEZ and 25 abroad employees on the detached place of work in the Spain and France
The operational safety of the V1 nuclear power plant (NPP) is unsatisfactory and does not correspond to present requirements as to nuclear safety. Further NPP operation after 1995 is conditional on nuclear safety enhancement to a level comparable with that in West European countries. This aim should be achieved by a principal reconstruction involving in addition to others also backfitting the V1 NPP with technical facilities aimed at coping with a design basis accident (DBA).To cope with such an accident the Power Equipment Research Institute (VUEZ) designed an accident localization system with jet condensers. This system consists of (a) an air trap (one for each unit, mutually interconnected) with an expansion bell enclosed within, placed on a plate with 200 pipes of jet condensers passing through, and (b) a connecting duct between the hermetic zone and the air trap. The vertical jet condenser is an essential element of the system designed for steam condensation. Apart from condensation it serves as a water seal separating units 1 and 2.Demonstration tests of the jet condenser (model 1:1) condensing function were carried out at the testing unit of the All-Union Research Institute for NPP Operation (VNIIAES), Moscow in Kashir, 11-22 September 1992. These experiments proved the jet condenser ability to ensure complete condensation of the steam produced. Experimental verification of the sealing function (model 1:1) was carried out at the testing unit of the VUEZ Tlmace. These experiments concerning the dynamics and overpressure in the free space above the pool were close to the conditions in the air trap during DBA. The jet condenser height was proved to be sufficient to ensure the sealing function. Design and experimental work has been implemented in close cooperation with Russian experts Mr. V.N. Bulynin from the VNIIAES, Moscow, and Mr. M.V. Kuznecov from the Scientific and Engineering Center for Nuclear and Radiological Safety, Moscow. (orig.)
In order to meet its obligation to keep a 90-day emergency reserve of oil and oil products, Slovakia must purchase about 40% of the required volume of these commodities and complete storage capacity for the reserves. In addition, it must also create a system of storage management for the reserves including a regular exchange of the contents of the tanks. If it does not meet the 2008 deadline, EU structural funds will be decreased. In order to create the missing storage capacity, the Sprava statnych hmotnych rezerv (SSHR - Administration of Public Material Reserves) is considering a solution which Slovnaft, a.s. sees as a major risk for the state. Should the hundreds of millions needed for the building of new tanks not be found in the budget, the state would invite private investors to build the tanks, stated SSHR Chairman, Jan Tusim. Private investors will not endanger public control over the emergency reserves. Other countries also lease tanks. But according to information provided by its chairman, SSHR also wants to make the private investors responsible for the regular exchange of the emergency reserves that must be carried out every four to five years. Given an accurate forecast of price development on international markets, a lot of money can be made on these exchanges. Slovnaft stresses that if the state were no longer responsible for the exchange of the tanks' contents, it would be the state that was at risk not the refineries

Many of the operating nuclear power plants are approaching their design life. In response, the IAEA initiated Extrabudgetary Programme on Safety Aspects of Long Term Operation (SALTO) of Water Moderated Reactors (Programme). The Programme's objectives are to assist those Member States considering LTO of water moderated reactors in how best to reconcile the related processes and practices; how to establish a general LTO framework; and finally, it provides a forum in which Member States can freely exchange information. The main goal of project was to develop an internationally agreed document that will provide MS with specific guidance for long term operation. Collection of WWER specific information by all participants increased quality and unification of national programmes. Original design plant life of 30 years is planned to be extended by 10 years to the overall period of 40 years of operation. The Programme activities were guided by the Programme Steering Committee (SC), follow the overall SC Programme Workplan and SC Terms of Reference, and are implemented in 4 Working Groups (WG). The WGs focus on: - general LTO framework (WG 1); - mechanical components and materials (WG 2); - electrical components and I and C (WG 3); - structures and structural components (WG 4). VUEZ, a.s., Levice participated on activities for structural components implemented in 4 th Working Group. This programme was finished and final report was published. In this article we bring a short presentation of the SALTO project and the report. (authors)
Summary of findings: 1) Thermal and technological settings for PSS inside hermetic volumes of VVER-44%/213 are correct and reproducible. Performance with some specific features (passive spraying) is necessary to increase efficiency of thermal capacity of water in the bubble tower. Additional technological elements ensuring this function (special check valves, withholding and collecting device of water pouring-off from water trays). The PSS can withstand twice higher overload in comparison with DBA coming from flow of noncondensible gases, the flow cross section of the DN500 check valves to airlock volumes imposes limitation of overloading of the system because of pressure increase in the volume of PSS. 2) Generic checking of seismic resistance of PSS shows in some extent contradictory results. For combined loadings of two types-nominal operation + maximum computational earthquake and DBA + design earthquake - stress in the PSS piping exceed limiting values. Also dynamic forces in PSS bearing system for combined loading of nominal operation and maximum computational earthquake exceed limiting values (approx. 10%). At the analytical modelling of DBA, effects of pressure shock were not included. 3) Efficiency of the spray system depends on the flowrate of the coolant, temperature of water, and on the contents of air in the atmosphere. Coming from available data for air concentration in the hermetic volumes, design flow rates and temperatures of water the spray efficiency is sufficient. Experiment confirmed the design assumptions on spray efficiency if modelling conditions (pushing out of air and steam - air mixing) correspond to the NPP conditions. 4) VUEZ Tlmace results show different state of hermetic volumes for particular NPP units. Containment tightness of the older units is lower than design magnitude. Progression of corrosion does not impose limitation on lifetime of the units.
Intensive discussions within the OECD Support Group on 'VVER-440 Bubbler Condenser Containment Research Work' between 1991 and 1994 demonstrated the need for supplementary research work to achieve an adequate level of basic knowledge. In 1994, the European Commission (EC) asked for a specific 'VVER-440/213 Bubble Condenser Qualification Feasibility Study', which was finished early in 1996, confirming the need for additional research in this field. The Feasibility study formed the basis for the Bubble Condenser Experimental Qualification Project (BCEQ) with two separate experimental activities to be executed within the frame of the PHARE/TACIS 2.13/95 project of the European Commission. A first activity served to study the thermal-hydraulic phenomena and the associated structure dynamic interactions. This part of the project was performed at EREC, in Elektrogorsk, Russia. The design of the test facility was based on the prototypical bubbler condenser configuration for the Hungarian Paks nuclear power plant. A second activity addressed the structural integrity of certain components of the bubbler condenser steel structures under DBA-typical conditions. This part of the project was performed at VUEZ, in Levice, Slovak Republic. The design of the components of this facility was based on the structural properties of the Dukovany and/or Bohunice nuclear power plants. A third component of the BCEQ project was specified later asking for analytical studies, which should be supported by a number of small-scale separate effects tests to be performed at SVUSS, in Bechovice, Czech Republic. The main experimental and analytical results of the BCEQ test campaigns have been presented and discussed within the frame of the 4. meeting of the Technical Advisory Committee to the BCEQ (Bubble Condenser Experimental Qualification) Project in Brussels in December 1999 and on occasion of the 11. OECD Support Group Meeting in Berlin in April 2000. The discussions had evidenced several
