containment structure definition

Existing Structure An existing containment structure is defined as one whose installation began on or before November 16, 2006. The containment method, design, and capacity are determined by good engineering practice to contain the most likely discharge of oil until cleanup occurs. An approach using multiple fission product barriers has been adopted to deal with such accidents.

Practically all nuclear power plants built during the last few decades include a containment building. Containment is the process of preventing pollution or contamination of the immediate site environment by dust, debris, abrasives, chemicals, sprays and other materials that have been applied to prevent corrosion. Existing Structure An existing containment structure is defined as one whose installation began on or before November 16, 2006. Other articles where Containment is discussed: Walter Reckless: …generalized this finding into a containment theory, which argued that there are inner and outer forces of containment that restrain a person from committing a crime: the inner forces stem from moral and religious beliefs as well as from a personal sense of right and wrong; the outer forces come… Walter Reckless, in fullWalter Cade Reckless, (born January 19, 1899,Philadelphia,Pennsylvania, U.S.—died September 20, 1988, Dublin, Ohio), American criminologist known for his containment theory ofcriminology, which stated that juveniledelinquencycommonly arises from a breakdown inmoral and social forces that otherwise “contain”deviantbehavior. Definition 3.1 (Subset and Containment Query Problem, Subset Dictionary) Let D be a set of n subsets over a universe Γ.The Subset Query (C ontainment Query) problem asks for any query set q ⊆ D if there is any p ∈ D with q ⊆ p (p ⊆ q).. A subset dictionary is an abstract data structure providing insertion of sets to D while supporting subset and containment queries. 2. uncountable noun. Containment Policy .
