Rozhodl jsem se psát tuto práci, protože si myslím, že o jaderné energii koluje dost pověr polopravd a omylů.Např. lidi si myslí, že reaktory jsou nebezpečné, ale to nebezpečné na nich je hlavně možnost lidského selhání. Ta se ovšem může snížit v tom případě, pokud u reaktorů budou pracovat kvalifikovaní a opatrní lidé. Uvést to vše na pravou míru je velice zajímavé téma na seminární práci. V této práci se například dozvíte: kdo první spustil řízenou řetězovou reakci, co se stalo 26. dubna 1986, jaké jsou různé typy reaktorů , jak pracují jaderné reaktory na 235-U, 238-U i 239-Pu či o přeměnách atomu na jiný, což vyvrátilo základ chemie a mnoho dalšího. 2.CO je Radioaktivita ??? Radioaktivita je způsobená tím, že pro některé izotopy různých prvků není jejich (energetický)stav výhodný. Můžou použít různé typy radioaktivního rozpadu, aby v jednom či více krocích dosáhly stability- 3 3 např.

We found that, in a sample of five random years, the worldwide historical frequency of a nuclear major accident, defined as an INES level 7 event, is 14%. This value is 67 % to have at least one nuclear accident rated at level ≥ 4 on the INES scale. These numbers are subject to uncertainties because the fuzziness of the definition of a nuclear accident.

  • Manuscript Title in Title Case
    Natural Uranium as Alternative Fuel for TEPLATOR Tomáš Peltan University of West Bohemia Univerzitni 8 30100, Pilsen, Czech Republic [email protected] Eva Vilímová, Radek Škoda University of West Bohemia Univerzitni 8 30100, Pilsen, Czech Republic [email protected], [email protected] ABSTRACT The TEPLATOR is an innovative solution for district heating using nuclear energy. It is a special thermal reactor with specific arrangement of the reactor core with 55 fuel assemblies which is moderated and cooled by heavy water and operated at atmospheric pressure with low output temperatures compared to the commercial nuclear power plants. The TEPLATOR DEMO is designed for using irradiated fuel from LWR reactors. In case that the irradiated fuel is not available in terms of high burnup or other reasons, there is a possibility to use SEU or natural uranium as a fuel. This solution is suitable because of the favourable price of natural uranium. This article focuses on development of the alternative suitable fuel for the TEPLATOR, which is based on irradiated fuel reactor core arrangement. It is mainly concerned with neutronic development of the fuel assemblies with appropriate parameters for this application. This article contains various fuel modifications with different time of operation. All calculations were performed by the Monte Carlo code Serpent. 1 INTRODUCTION The TEPLATOR is designed as a new type of reactor for operation with the irradiated VVER-440 fuel assembly with optimal burnup. The reactor will be used as a district heating station. This solution could be interesting for countries, which operate VVER-440 reactors, and which have a large amount of irradiated fuel assemblies stored in long-time storage.

  • NRC Regulatory History of Non-Light Water Reactors (1950-2019)
    BNL-211739-2019-INRE NRC Regulatory History of Non-Light Water Reactors (1950-2019) Manuscript Completed: June 10, 2019 Prepared by: Pranab Samanta, David Diamond, and William Horak Nuclear Science and Technology Department Brookhaven National Laboratory Upton, NY 11973-5000 Prepared for: Imtiaz Madni and George Tartal Office of New Reactors U.S. Nuclear Regulatory Commission ABSTRACT This report describes the U.S. Nuclear Regulatory Commission’s (NRC’s) history with the licensing of non-light water reactors (non-LWRs). The focus is on regulatory policy and licensing issues that have arisen in the past so that NRC staff will be in a better position to deal with these matters in the future. It is not an objective to discuss in any detail the technology of non-LWR designs. Documenting the historical policy issues and licensing approaches is particularly important to NRC staff unfamiliar with non- LWRs and is an important incentive for the report. Hence, the report is written as a tutorial rather than as an historical archive. The subject is approached chronologically going from the early days of the Atomic Energy Commission to the formation of the NRC, then into the era when the regulatory structure newly developed for LWRs provided guidance for other types of reactors, followed by the era when policy was made specifically for advanced reactors including non-LWRs. This background provides the transition to current planning for future non-LWR licensing and policy─also described herein. iii TABLE OF CONTENTS ACRONYMS ...................................................................................................................vi 1 INTRODUCTION ................................................................................................... 1-1 1.1 Background ............................................................................................... 1-1 1.2 Objective ..................................................................................................

  • Manuscript Title in Title Case
    MCNP Calculations in Connection to the Decommissioning Scenario Amine Bouhaddane Institute of Nuclear and Physical Engineering, Faculty of Electrical Engineering and Information Technology, Slovak University of Technology in Bratislava Ilkovičova 3 Sk-81219, Bratislava, Slovakia [email protected] Gabriel Farkas, Vladimír Slugeň Institute of Nuclear and Physical Engineering, Faculty of Electrical Engineering and Information Technology, Slovak University of Technology in Bratislava Ilkovičova 3 Sk-81219, Bratislava, Slovakia [email protected], [email protected] ABSTRACT This paper is focused on the detailed look on the radionuclide inventory determination as an essential part of the decommissioning strategy selection process and as a prerequisite for the radioactive waste management. Based on the radionuclide inventory calculation, it is possible to optimize the time frame and to choose the appropriate dismantling procedure during the disposal of reactor internal and external components in the decommissioning phase of a nuclear power plant (NPP). MCNPX code enables precise three-dimensional modelling of these components. Due to high technological and financial demands in the case of in situ measurements or sampling, it is important to use validated code systems to precisely estimate the radionuclide inventory. The required precision of modelling depends on the expected decommissioning method. The essential part of a correct calculation is the collection of reactor operation data. In this paper, the ability of the MCNPX code in this field is presented by the example of calculation for the reactor internal components used in a VVER-440 reactor. As parts next-to the reactor core these are the most radioactive components besides the spent nuclear fuel.

    e-news issue 45, Summer 2014 http://www.euronuclear.org/e-news/e-news-45/issue-45-print.htm European Nuclear Society e-news issue 45: July 2014 ENS NEWS N° 45 : Learning the lessons of Rio I was recently in Budapest for an international nuclear conference that was attended by senior government and EU officials, representatives of the nuclear industry and other stakeholders. It focused on the current state and future direction of the nuclear industry in Europe, on EU energy policy in general – and nuclear in particular – and on the latest reactor technology in support of global new build. The importance of the agenda and the stature of the speakers present, which included ENS Secretary General, Jean-Pol Poncelet, were matched only by the keen interest shown by delegates in a global phenomenon that is currently sweeping the world. No, it’s not nuclear new build, but a sporting event that generates commercial and media interest of gigantic proportions; an event that fires the imagination, stirs the passion and involves sums of money that make your eyes water. Well, unless you have spent the past couple of weeks on a penal colony on Venus, you can’t have failed to notice that the 2014 FIFA Football World Cup has been monopolising the world’s TV channels, dominating the media and preoccupying the waking hours of millions of football addicts around the world. I am reliably informed that this sporting extravaganza, with its iconic pictures of the Copacabana Beach, the Sugar Loaf Mountain and the Corcovado, is even popular with people who don’t usually follow football.

  • Nuclear Regulatory Authority Requirements - First Phase of Npp A-1 Decommissioning
    WM’01 Conference, February 25-March 1, 2001, Tucson, AZ NUCLEAR REGULATORY AUTHORITY REQUIREMENTS - FIRST PHASE OF NPP A-1 DECOMMISSIONING Jana Burclová, Ladislav Konecný Nuclear Regulatory Authority of Slovak Republic, Okruzna 5, Trnava , Slovakia E-mail address: [email protected] ABSTRACT Pilot nuclear power plant A-1 was a HWGCR (heavy water gas cooled reactor) with channel type reactor KS 150 (refuelling during operation) and power output of 143 MWe. This NPP was operated from 1972 and was shutdown in 1977 after integrity accident of the primary coolant system. Significant damage and corrosion of the fuel cladding during the operational accident and during spent fuel storage at NPP A-1 caused consequently to existence of abnormal radioactive waste (containing alpha nuclides) and to the contamination of NPP parts. However decision on decommissioning of NPP A-1 was assumed in 1979, the start of A-1 decommissioning was delayed and progressing slowly. The start of decommissioning was based on "case by case" strategy for the lack of specific regulations. First activities were focused to the transfer of spent fuel from the site and to dismantling of some non-radioactive parts. The decommissioning plan for the first phase prepared in 1993 – 1994 was amended in 1995/96. Under Atomic energy act requiring decommissioning plan (1998) the permission for the first phase was issued. The goal of this phase (planned till the year 2008) is: a) to transfer spent fuel to Russian Federation or to improve the safety of its storage b) to improve the safety standard for storage of radioactive wastes and enable their conditioning and disposal c) to remove contamination and prepare some parts for dismantling and demolition INTRODUCTION Nuclear power plant A-1 in Jaslovské Bohunice was commissioned in 1972 and was shutdown in 1977 after primary coolant system integrity accident with local melting of the fuel.
