In the SBLOCA, all components of the passive safety system were put into work sequentially, which prevented the core uncover.
A SBO is one of the most important DECs in that without any proper operator actions, a total loss of heat sink leads to core uncover, to core damage, and ultimately a core melt-down scenario under high pressure.
Experimental data indicates that this LB LOCA is successfully mitigated by the functioning of Emergency Core Cooling System (ECCS) and Passive Containment Cooling system (PCCS), with no occurrence of core uncover or containment overpressure.
That apparently is what happened at least one of the reactors, leaving the upper part of the cores uncovered until technicians, in what has been described as a desperate measure, rigged up a way to pump seawater in.
A life-cycle assessment commissioned by Levi Strauss & Co in 2007 into two of its core products uncovered some unexpected results – one of the largest environmental impacts of its products was the use of water.
In addition, fixing the core can uncover the most natural sort of growth through adjacencies.
The objective of this research is to evaluate the ability of passive safety systems in this BWR to keep core from uncover and containment from overpressure during a SB LOCA transient by reproducing the LOCA transient in the test facility.
Computation of the core genome uncovered a number of essential gene clusters with a remarkably stable chromosomal position across species, in sharp contrast with the scrambled nature of their genomes.
One interesting effect, uncovered by the report, is the withdrawal of subjects that do not fit into, to use the DfE's words, "a core of academic subjects; English, maths, history or geography, the sciences and a language".
