Generation III Russian reactor, which is planned to be built in Hungary As it is developed from the earlier approved design model, there are several common features between the original and the new designs The main developments are the cycle length which can achieve 500 full power days meanwhile the probability of severe damage to the core for all operating regimes must be less than 10-7 1/yr In fact, reactor core cycle length depends mainly on the arrangement of different fuel assemblies with the type and concentration of poisons and cluster regulating system used inside the core Any improvements in these factors will increase the reactor cycle length and will also increase the average fuel burnup which will finally lead to enhanced economic performance Investigation of core improvements made for the new Russian reactor VVER-1200, has been done by the vendors, however appropriate indigenous calculation tools are advantages for the users, too In Hungary four VVER-440 Units work from the 1980 s As in-core fuel management of these reactors used to be performed by indigenous code system (Karate-440) which was developed in Hungary for VVER reactors about twenty years ago and used continuously, its development seems to be reasonable It was appropriate to create the new code complex Karate-1200 starting from the methods currently used very effectively for VVER-440 reactors This paper briefly summarizes the improvements of the code system and the properties of the possible fuel types can be applied to the AES-2006 reactor The new assemblies are modeled by using both the solvers of the Karate-1200 code system and MCNP respectively (author)}, year = {2018}, pages = {1159-1170} } @article{MTMT:3315948, title = {SFCOMPO-2.0: An OECD NEA database of spent nuclear

At the same time, new fuel types with higher enrichment and containing pins with gadolinium have been introduced. Due to these plans, the radiation load of the pressure vessel was evaluated up to 60 years irradiation, taking into account the past and planned future cycles. The computational procedure, elaborated and validated earlier for the fast flux calculation in the pressure vessel was modified for the new fuel types. The neutron source at the core boundaries was taken from core design calculations and the neutron transport from the source to and through the pressure vessel was followed by Monte Carlo calculations. A number of calculations were performed to adequately follow the change of the neutron source. The paper details this procedure, the used Monte Carlo model, the influence of the different reloading schemes on the radiation load and the calculated results.}, year = {2016}, eissn = {2100-014X} } @article{MTMT:3120735, title = {Reactor Dosimetry Aspects of the Service Life Extension of the Hungarian Paks NPP}, url = {https://m2.mtmt.hu/api/publication/3120735}, isbn = {9782759819294}, author = {Zsolnay, Éva and Czifrus, Szabolcs and Fehér, Sándor and Hordósy, Gábor and Keresztúri, András and Kresz, N and Oszvald, F}, doi = {10.1051/epjconf/201610602010}, journal-iso = {EPJ WEB CONF}, journal = {EPJ WEB OF CONFERENCES}, volume = {106}, unique-id = {3120735}, issn = {2101-6275}, year = {2016}, eissn = {2100-014X} } @inproceedings{MTMT:27188015, title = {Evaluation of the Full Core VVER-440 Benchmarks Using the KARATE and MCNP Code Systems}, url = {https://m2.mtmt.hu/api/publication/27188015}, author = {Hegyi, György and Hordósy, Gábor and Maráczy, Csaba and Temesvári, Emese}, booktitle = {24TH INTERNATIONAL CONFERENCE NUCLEAR ENERGY FOR NEW EUROPE, (NENE 2015)}, publisher = {Nuclear Society of Slovenia}, unique-id = {27188015}, year = {2015} } @inproceedings{MTMT:3019809, title = {Evaluation of theFullCore VVER-440 BenchmarksUsingthe KARATE and MCNP Code Systems}, url = {https://m2.mtmt.hu/api/publication/3019809}, author = {Hegyi, György and Hordósy, Gábor and Maráczy, Csaba and Temesvári, Emese}, booktitle = {NENE2015 Symposium}, unique-id = {3019809}, year = {2015} } @inproceedings{MTMT:3019653, title = {HPLWR Fine Mesh Core Analysis}, url = {https://m2.mtmt.hu/api/publication/3019653}, author = {Temesvári, Emese and Maráczy, Csaba and Hegyi, György and Hordósy, Gábor and Molnár, Attila}, booktitle = {The 7th International Symposium on Supercritical-Water-Cooled Reactors (ISSCWR-7)}, unique-id = {3019653}, year = {2015}, pages = {141-151} }
