The REPAS Study: Reliability Evaluation of Passive Safety Systems
10th International Conference on Nuclear Engineering, Volume 2, 2002The strategy of approach to the problem moves from the consideration that a passive system should be theoretically more reliable than an active one. In fact it does not need any external input or energy to operate and it relies only upon natural physical laws (e.g.

Abstract The design concept of integrated passive safety system (IPSS) which can perform various passive safety functions is proposed in this paper. It has the various functions of passive decay heat removal system, passive safety injection system, passive containment cooling system, passive in-vessel retention and cavity flooding system, and ...

18th International Conference on Nuclear Engineering: Volume 3, 2010
The paper presents three types of a passive safety containment for a near future BWR. They are tentatively named Mark S+, Mark D and Mark X containments in the paper. They all have a leak tight secondary containment vessel (SCV) in order to meet the reactor site criteria without relying on an active standby gas treatment system at a DBA LOCA.

Abstract The paper presents two types of a passive safety containment for a near future BWR. They are named Mark S and Mark X containment. One of their common merits is very low peak pressure at severe accidents without venting the containment atmosphere to the environment. The PCV pressure can be moderated within the design pressure.

TEPSS–Technology enhancement for passive safety systems
Nuclear Engineering and Design, 2001Abstract The objective of the technology enhancement for passive safety systems (TEPSS) project TEPSS Final Report, INNO-TEPSS(99)-D21 (1999)) was to make significant additions to the technology base of the European simplified boiling water reactor (ESBWR). The project focused on mixing and stratification phenomena in large water pools, passive decay

From Passive to Active Safety Systems
2007State of the art automotive restraint systems have reached a very high level of occupant protection. Vehicle construction, belt and airbag systems are the most important lifesavers in this respect. The vehicle installation rate of restraint systems covers almost 100%.

Passive safety system of a super fast reactor
Nuclear Engineering and Design, 2015Abstract Passive safety systems of a Super Fast Reactor are studied. The passive safety systems consist of isolation condenser (IC), automatic depressurization system (ADS), core make-up tank (CMT), gravity driven cooling system (GDCS), and passive containment cooling system (PCCS).

Passive modular gas safety system for a reactor
Atomic Energy, 1993Reactor safety systems have developed gradually. Today in particular, auxiliary systems are being developed which are based on nontraditional operational concepts, by using gaseous neutron absorbers. The Scientific-Research and Design Institute of Power Technology (NIKIET) and the Institute of Nuclear Reactors, Kurchatov Institute Reactor Science ...

Intelligent safety systems integrating active and passive safety
2007Side crashes occur relatively often and the injury risk in a side crash is higher than in a frontal crash due to the small distance between the occupant and the impacting object. For the same reason, little time is available for optimal deployment of collision mitigation measures using in-crash detection technology.
