Simulation and analysis of pipe and vessel blowdown phenomena using RELAP5 and TRACE

Gurgacz S., Pawluczyk M., Niewiński G., Mazgaj P.

Journal of Power Technologies

2014

Vol. 94, nr 5

61--68

This paper presents the results of a pipe and vessel theoretical blowdown analysis in order to identify and assess rapid depressurization phenomena occurring during a Loss of Coolant Accident in a nuclear power plant. Calculations were performed in conditions similar to those in a reactor pressure vessel. Due to critical two-phase flow occurrence, RELAP5 mod 3.3. and TRACE v 3.0 system codes were used for this purpose and a computational model was built on the basis of available literature and implemented in MATLABr code. Finally, pipe depressurization results were compared to experimental results taken from the literature.

Implementation of pre-operational version of RODOS System in the Center for Radiological Events of the National Atomic Energy Agency in Poland

Borysiewicz M., Potempski S., Żelazny R.

Journal of Technical Physics

2002

Vol. 43, no 3

287-307

This paper is devoted to the comprehensive description of the implementation of the RODOS System in the Center for Radiological Events (CEZAR) of the National Atomic Energy Agency in Poland. First the history of the RODOS Project of the European Commission is presented, followed by the description of the structure and modules of this comprehensive Software Package, aimed to assist in the management of the nuclear emergency problems following the nuclear accident in Europe. Then the adaptation of the software to Polish national conditions is explained taking into account the radiological data prevailing on the Polish territory. All the data bases connected with meteorology, contamination transport parameters in humans and their ecological systems have been collected and applied to meet the specific dietary habits, soil structures, agricultural situation and other specific condition in this country. Those data have been introduced into the system after appropriate adaptations to the specific requirements of the modules of the RODOS System. Furthermore, the network system connected with the RODOS prc-operational version in CEZAR is described enabling on-line cooperation with the Institute of Meteorology and Water Management (IMWM) and the Central Laboratory for Radiological Protection (CLOR) as well as with the Institute of Atomic Energy (IAE), which plays the role of Technical Support Organization with respect to this System. IAE has participated in the development of the RODOS System within tlie 4-th and 5-th Research Frameworks of EU and acknowledges here with gratitude the Implementation Grant from the State Committee of Scientific Research and National Atomic Energy Agency in Poland. This Grant has created the basis for the implementation of the RODOS System in Poland within tlie framework and assistance of the ECHO contract of the EU.
