A cargo containment system is the total arrangement for containing cargo including, where fitted: A primary barrier (the cargo tank), Secondary barrier (if fitted), Associated thermal insulation, Any intervening spaces, and; Adjacent structure, if necessary, for the support of these elements.
Cargotec was formed in June 2005 when Kone Corporation was split into two companies to be listed: Cargotec and new Kone. After the split, Kone Corporation's marine cargo handling (MacGregor), container handling (Kalmar Industries AB) and load handling (HIAB and Moffett, the latter being based in Ireland and acquired in 2000) business units formed Cargotec.
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
This system consists of a series of pumps and spargers that spray coolant into the upper portion of the primary containment structure. It is designed to condense the steam into liquid within the primary containment structure in order to prevent overpressure and overtemperature, which could lead to leakage, followed by involuntary depressurization.
This is a list of primary and secondary school tests. Tests available at the end of secondary school, like Regents Examinations in New York , California High School Exit Exam , GED across North America , GCE A-Level in the UK, might lead to a school-leaving certificate ( diploma ).
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in inadvertant criticality.
Most nuclear power plants feature a containment building whose role is to be the ultimate barrier, as per the defense-in-depth principle, against the release of radionuclides in the environment during accidents involving partial or total reactor core damage, that is, in which the integrity of the nuclear fuel (first barrier) is lost.
It has 4 coolant loops with 1 steam generator per loop. There are concrete walls between loops and the hot and cold parts of each loop to protect against failures. Besides the double layer containment there is a concrete wall surrounding the primary system components inside the containment. [18]
