The phrase "accidental sequence" is correct and usable in written English.
It can be used to describe a series of events or elements that occur by chance or without intention.
Example: "The accidental sequence of events led to an unexpected outcome that surprised everyone involved."
Alternatives: "unintentional order" or "chance arrangement".
The accidental sequence is described: fire, LNG release, further safety valves release, flames impingement on vessel unprotected wall, vessel failure mode, explosion and fireball.
In particular, this paper shows an application of MELCOR code to model beryllium steam reaction in a particular accidental sequence for the long term cooling.
Safety analysis of the reference accidental sequence has been carried out for Lead Lithium cooled Ceramic Breeder (LLCB) Test Blanket Module (TBM) system; India's prototype of DEMO blanket concept for testing in International Thermonuclear Experimental Reactor (ITER).
The re-irradiation phase is not a part of the LOCA accidental sequence but it is modeled to provide a study concerning the nominal and abnormal conditions by finding out the device thermal-hydraulic limits.
A deterministic assessment of the main accidental sequences has been performed.
Because of this, some of the most relevant accidental sequences see a reduction of releases and of doses to public, due to radioactive source terms reduction.
The deterministic analysis has achieved the following results: the Ignitor machine, both during routine operation and accidental sequences, presents a negligible environmental impact and radiological risk.
Since, in this way, it is possible to advance in the development of safety systems, prediction of situations likely to produce accidental sequences, etcetera.
For the Helium Cooled Pebble Bed (HCPB) blanket concept (version 2014) three representative accidental sequences of LOCA have been simulated using system code MELCOR 1.8.6 for fusion.
This paper analyzes the deterministic consequences of two accidental sequences, serving as the "design basis accidents" because of the extent of radioactive release involved, either outside or inside the building.
Crossword-puzzle solvers rely heavily on the relative probabilities of letter sequences in written words to suggest an answer to a partly filled line, and, depending on the particular style of the originator, crossword clues make use of many sorts of formal features in the language, among them spelling puns, spoken puns, and accidental letter sequences in words and phrases.
