Pattern recognition algorithm for analysis of chugging direct contact condensation
(Elsevier, 2018)
Direct contact condensation of steam bubbles in a boiling water reactor suppression pool has long been studied utilizing video recording of experiments. The use of video recording enables observation of the behaviour of ...
System code analysis of accumulator nitrogen discharge during LOCA experiment at PWR PACTEL test facility
(Elsevier, 2019-08-20)
The hydroaccumulators in pressurized water reactors can inject nitrogen into the reactor system. In the primary system, nitrogen affects core cooling and accident management, both adversely and beneficially. The PWR PACTEL ...
Frequency analysis of chugging condensation in pressure suppression pool system with pattern recognition
(Elsevier, 2018-12-01)
Direct contact condensation (DCC) phenomena in boiling water reactor (BWR) pressure suppression pool systems need to be understood to properly assess the performance of the pool as a heat sink and as a safety critical ...
Reactor core conceptual design for a scalable heating experimental reactor, LUTHER
(MDPI, 2021-06-01)
In this paper, the conceptual design and a preliminary study of the LUT Heating Experimental Reactor (LUTHER) for 2 MWth power are presented. Additionally, commercially sized designs for 24 MWth and 120 MWth powers are ...
Image Analysis of Bubbling Mode Condensation Oscillations in Horizontal Sparger
(American Nuclear Society, 2019-08-23)
Pattern recognition based image analysis algorithm was developed for analyzation of bubbling mode
condensation oscillations in horizontal spargers. Safety relief valve test rig SEF-POOL was filled with a
heated up (85 ...
Efficiency of Passive Open Loop Heat Removal Over Wide Range of Loop Flow Resistances – PASI Loop Tests in the EU-PASTELS Project
(American Nuclear Society, 2023-11-23)
The PASI test facility, designed and constructed at LUT University, is a model of a containment cooling system using an open passive heat removal loop. The PASI facility consists of a pressure vessel simulating containment ...
Development and Validation of Pattern Recognition Algorithm and Suppression Pool Flow Modelling
(American Nuclear Society, 2023-08-25)
The comprehensive understanding of the dynamics of vapour bubbles and jets discharged from vent pipes and spargers into subcooled liquid has a significant role in assessing the capability of nuclear safety systems to perform ...
