Passive safety systems have been widely applied to advancedwater-cooled reactors (WCRs), to enhance the safety ofnuclear power plants. For the near term and medium term,the Chinese government decided for advanced pressurizedwater reactors with an extensive usage of passive safetysystems. The International Workshop on Passive SafetySystems of Advanced PWR (IPASS’08) was held in Shanghaion April 28–30, 2008, coorganized by the Shanghai Jiao TongUniversity and the Pisa University. The main purposes ofthe Workshop IPASS’08 are (a) to provide a platform to theinternational nuclear community for exchanging researchresults and design experience on passive safety systemsapplied to advanced WCR and (b) to enhance the contact andcollaboration between the Chinese research institutions andinternational partners.
More than 100 scientists and nuclear engineers fromeight countries, that is, Canada, China, France, Germany,Italy, Korea, Pakistan, and USA, were participating in thisworkshop. More than 60 technical papers were presentedcovering the following topics:
(a) safety injection and decay heat removal systems,
(b) passive containment cooling systems and hydrogensafety research,
(c) passive systems for severe accident mitigation,
(d) assessment and application of numerical tools,
(e) single effect and integral verification experiments,
Eight papers were selected for this special issue. The firstpaper of Cheng et al. [1] gives a summary about the Chineseresearch activities on passive safety systems of advancedPWR. Experimental studies and validation of numerical
codes are presented in the following two papers [2, 3].The paper of Gou et al. [4] deals with numerical analysisof the performance of passive safety systems; whereas themethodology for the reliability assessment of passive safetysystems is investigated in the paper of Pierro et al. [5]. Thelast three papers are devoted to hydrogen safety issue, whichis a main topic of the workshop [6–8].
The editors of this special issue express thanks to allauthors for their contribution.
