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.

Rekonstrukce jaderných deviací: Politika stigmatu a normy nešíření jaderných zbraní

OpenAIRE

Smetana, Michal

2017-01-01

In this dissertation, my aim is to unpack the relationship between deviant behavior and normative change in global nuclear politics. I draw on the interactionist approach in sociology to conceptualize "stigma politics" as an interactive, dynamic process of the social construction of deviance in international affairs. I connect these insights with contemporary IR theories on norm contestation to theorize the way how (re)constructions of deviance contest and affirm boundaries of appropriate beh...

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.

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.

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)
