    Full Text Available Na plochách v Tatranskom národnom parku, ktoré boli postihnuté veternou kalamitou v roku 2004 a požiarom v roku 2005, sme študovali pôdne mikrobiálne spoločenstvo. Cieľom tejto práce je porovnať odozvu pôdnych mikroorganizmov na rozdielny manažment plôch a hodnotiť vývoj mikrobiálneho spoločenstva v priebehu rokov 2006-2013. Pôdne vzorky sme odoberali z A-horizontu pozdĺž 90 m dlhého tranzektu na 4 plochách (referenčná plocha, plocha s vyťaženou drevnou hmotou, plocha po požiari, plocha s nevyťaženou drevnou hmotou. V pôdnych vzorkách sme stanovovali bazálnu a potenciálnu respiráciu, mikrobiálnu biomasu, N-mineralizáciu, aktivitu katalázy, abundanciu a diverzitu funkčných skupín pôdnych mikroorganizmov použitím BIOLOG Eco platní. Vo všeobecnosti, najvyššiu aktivitu a biomasu pôdnych mikroorganizmov sme zaznamenali na ploche referenčnej a ploche po požiari. Nezistili sme významné rozdiely medzi plochou vyťaženou a nevyťaženou. Na všetkých kalamitných plochách sme v sledovanom období zaznamenali mierny trend nárastu hodnôt mikrobiálnej biomasy, potenciálnej respirácie a N-mineralizácie, čo poukazuje na proces postupnej obnovy mikrobiálneho spoločenstva na kalamitných plochách.

    VUJE foundation is closely connected with the history of Bohunice nuclear power plant. The team of research and development employees in Bohunice nuclear power plant formed the basis for foundation of the Vyskumny ustav jadrovych elektrarni (Nuclear Power Plant Research Institute - hereinafter referred to as VUJE or Company). Institute started its operations on January 1, 1977 as a concern company of Slovenske energeticke podniky (Slovak Power Enterprises). One year later VUJE became an independent organization controlled directly by the Federal Ministry of Fuels and Power. Excellent results were the impulse for the federal government to accredit VUJE in 1983 to lead the scientific commissioning of all nuclear power plants in Czechoslovakia. In 1983 started VUJE the branch education and training centre, which was in the next year equipped with a full-range simulator of WWER 440/213 reaktor unit. This centre gradually achieved international recognition. The international Atomic Energy Agency in Vienna also carried out training courses here. VUJE moved its headquarters to Trnava in 1985, however multiple experimental facilities, development workshops and some laboratories stayed in the area of nuclear power plants in Jaslovske Bohunice. At the end of the eighties VUJE counted 759 employees and gained an important position not only in Czechoslovakia, but also within international nuclear power industry. Important changes in the whole society in 1989 also influenced the future in the institute. Management developed a new organizational model of VUJE and step-by- step also the institute's strategy and line of business. Company retained its focus and was transformed in to a state company. In the following privatisation the joint-stock company established by the institute's employees bought the state research institute. The institute was transformed into a private joint-stock company Vyskumny ustav jadrovych elektrarni Trnava, a.s as of November f 1, 1994. A The

    This contribution deals with the form, present state, and results of the Nuclear Power Plants Research Institute (the Slovak acronym is VUJE - Vyskumny Ustav Jadrovych Elektrarni) participation in the NPP V-2 Jaslovske Bohunice Modernization and Safety Improvement Project. A short description of VUJE history, activity, and results is also presented as well as NPPs Jaslovske Bohunice characterization. VUJE was established in 1977 and deals with scientific and research needs of nuclear power plants, such as design, construction, commissioning and operation. The next fields of VUJE activity are, NPP reconstruction, NPP personnel training, radioactive waste management technology, and NPP decommissioning. The nuclear power plant, Jaslovske Bohunice, is situated approximately 15 km from the district town of Trnava in the southwestern region of the Slovak Republic. The construction of the first Czechoslovak NPP A-1 began on this site in 1957 .The construction of the double-unit NPP V-1 with WWER-440 (type V-230) reactor began in 1972. The first unit of NPP V-1 began operation in 1978 and the second in 1980. NPPs construction on the Bohunice site continued with NPP V-2, which has two units with WWER-440 (type V-213) reactors. Unit 1 and Unit 2 of NPP V-2 were commissioned in 1984 and 1985, respectively. Slovak electric utility Slovenske elektrarne (SE) is the owner/commissioner of NPP V-2. This NPP is responsible for more than 20% of the total electrical energy production of SE, making it an essential supporter of the Slovak economy. (authors)

    The paper reviews the domestic efforts devoted to the safe and reliable operation of the Krško nuclear power plant (NPP) at full power, close to the design limit of the steam generators (18% of plugged tubes) for a full decade. This includes an overview of the recent status and history of the degradation processes, discussion of repair criteria, defining the acceptable size of defects and selected results from safety analyses supporting the operation of degraded steam generator (SG) tubes.

  6. Should the service life of nuclear power plants be limited for technical reasons?; Mela by byt provozni zivotnost jaderne elektrarny z technickych duvodu omezena?

    German nuclear power plant operating licenses take into account the fact that the design lifetime of the facilities is 40 years. The technological lifetime, however, is governed by actual ageing processes and operational burden. The service life of nuclear power plants can be extended by replacement of the steam generator and by repair or replacement of the reactor pressure vessel or parts thereof. Attention is also paid to the reactor protection systems. (J.B.). 8 figs.

    After almost half a century under the shadow of communism, the Czech Republic is set firm on a path of radical economic reform aimed at restoring its ranking among the most developed states in the world. Through a 145 million pound investment in the independent Czech heat and power producer: Elektrarny Opatovice (EOP), National Power is applying lessons learned during the privatisation of the UK electricity industry to capitalise on the new spirit of liberalisation sweeping through the nation which stands at the very centre of Europe. The National Power Office in Prague is staffed by three men who, together with other specialists from National Power, are in daily contract with their EOP counterparts to share knowledge and best practice in areas ranging from operational maintenance to find management strategies. In a two-way process, EOP is providing National Power with first-hand knowledge of large district heating schemes with efficiencies of up to 90%. EOP operates the coal-fired Opatovice power station supplying 360 MW of electricity and 750 MW of heat. 6 photos.

    Full Text Available Výskum sa zameral na mladé porasty buka lesného (Fagus sylvatica a smreka obyčajného (Picea abies rovnakého veku (12 rokov, veľmi podobných dimenzií stromov, rastúcich na totožnom stanovišti. Na základe odberu vzorníkov celých stromov (všetky časti okrem jemných koreňov sme skonštruovali alometrické vzťahy pre stromové komponenty. Ako nezávislá premenná sa použila hrúbka na báze kmeňa (d0. Modely vyjadrili nielen biomasu konárov, kmeňa, hrubých koreňov a asimilačných orgánov, ale aj plochu asimilačných orgánov a špecifickú listovú plochu (specific leaf area; SLA. Zistili sme, že základné morfologické vlastnosti asimilačných orgánov varírovali pri obidvoch drevinách pozdĺž vertikálneho profilu koruny. V prípade smreka sa zistili odlišné hodnoty plochy ihlíc a SLA medzi jednotlivými ročníkmi ihlíc. Na úrovni stromu mali buky oveľa viac biomasy drevných častí ako smreky, opačná situácia bola pri asimilačných orgánoch. Preto hodnoty podielu medzi biomasou asimilačných orgánov a celkovou biomasou stromu, ako aj pomeru medzi plochou asimilačných orgánov a celkovou biomasou stromu boli výrazne vyššie pri smreku než buku. Na úrovni porastu mala smrečina vyššie hodnoty indexu listovej plochy, t. j. LAI (18,64 m2.m−2 v porovnaní s bučinou (12,77 m2.m−2. Kým biomasa asimilačných orgánov bola 4,6-krát väčšia v smrekovom než v bukovom poraste, biomasa drevných časti bola porovnateľná v obidvoch porastoch. Tieto kontrasty naznačujú výrazne odlišnú rastovú stratégiu, resp. alokáciu biomasy medzi bučinami a smrečinami v mladých štádiách
