Freezing underwater temperatures and high pressure foiled an earlier attempt to place a containment dome over the leak.

This next attempt will be similar to a containment dome that failed to work.

Shell had to postpone drilling after a spill containment dome was damaged by an accident during testing in the summer.

Next it placed a 125-tonne (280,000 lb) containment dome over the largest leak and piped the oil to a storage vessel.

The three containment domes over the reactors are made of 4ft m thick concrete.

But officials admit only one in ten has so far been contacted, making it harder to enforce the new containment measures.

Police could also use containment measures, such as 'kettling', to control crowds.

Their containment measures have also been helped by having small populations.

Activity in large parts of the economy has stalled since the government introduced containment measures.

Ideas for the reopening of travel between the members include the harmonisation of containment measures, such as social distancing and masks, and agreed hygiene requirements for airports and planes.

The key known unknowns are a containment strategy and a vaccine.

The government's containment strategy has caused businesses to temporarily shut down or scale back activity, putting the livelihoods of millions of people at risk.

When the authorities announced they were providing the bank emergency liquidity support in 2007, rather than reassuring depositors, the containment strategy scared them.

The lockdown bought the time to design a containment strategy.

Vaccines could be an effective element of a containment strategy, but only if they were to be widely available within two months of the start of a pandemic.

Within two weeks, that containment system will be able to swallow the entire daily flow.

The extra time will be used to develop a containment system that can withstand explosions or the burning heat of a forced reentry.

However, the design of a complex pressure containment system involves much more than the application of this formula.

She hit a rock pinnacle at 14 knots and received some severe damage to the outer hull and the containment system.

Remaining materials would be treated in place and then contained within an engineered containment system.

He said that as time passed, the risk of an actual breach of the containment vessel would also decrease.

If the containment vessel were to rupture from excess pressure, however, a plume of radioactive material would be released.

The document claims airstrikes left the steel containment vessel with 1,700 holes, letting in hundreds of tonnes of rainwater.

Has the containment vessel been breached?

Recent scans of one revealed the worst possible result: all the nuclear fuel that was in the reactor's furnace has melted and dripped down into the concrete outer containment vessel.

The group said performance was driven by 'very strong income performance and cost containment'.

We have carefully managed our resources throughout this period, implementing cost containment and liquidity enhancement measures so as to ensure the long-term resilience of our firm.

In the interests of cost containment, the regulations place a limit on the number of components that can be used.

Critics of the program suggest that this lack of structure represents a missed opportunity for public health advancement and cost containment.

Financially focused efforts in recent years have primarily focused on cost containment and stimulating attendance and hospitality revenues.
